1.6 Bus supply for RXB Konnex controllers
RXB controllers work without bus supply if the following conditions are adhered to:
Parameterize only using the Handy Tool (not with ETS3 or ACS). No integration in a building automation and control system (e.g. DESIGO, Synco). No changeover operation (sensor signal via bus). No outdoor temperature via bus. No master/slave combinations. Else, the Konnex bus, used by RXB room controllers for communications, requires a bus supply. Each controller consumes 5 mA. Thus, select the supply according to the number of controllers. We recommend the following products:
Manufacturer Type Designation
Siemens Building Technologies ACX95.320/ALG Power supply 320 mA
Siemens Automation and Drives 5WG1 125-1AB01 Power supply 160 mA
5WG1 125-1AB11 Power supply 320 mA
5WG1 125-1AB21 Power supply 640 mA
1.7 RXB Konnex controller communications
The RXB Konnex controllers support communications as defined in the Konnex specification.
This specification defines the following modes among others:
S-Mode = System mode. LTE mode= Logical Tag Extended Mode
This is a new mode which supports simpler engineering and is used with Synco.
1.7.1 S-Mode
This mode corresponds to EIB communications. Connections are established via ETS3 Professional and group addresses.
This ensures a link to the existing EIB environment. Refer to the EIB manual for more information on this mode.

Siemens RXB (KNX) Applications library CLC and RAD description of functions for CC-02 CM110384en_04 Building Technologies Introduction 21 Sep 2010
1.7.2 LTE mode
LTE mode was specifically designed to simplify engineering. Unlike with S-mode, there is no need to create the individual connections (group addresses) in the tool. The devices establish the connections themselves. To make this possible, the following was defined:
Every device or sub-device is located within a zone. Every data point (input or output) is assigned to a zone. Every data point (input or output) has a precisely defined name. Whenever an output and an input with the same name are located in the same zone, a connection is established automatically as shown in the following diagram.

2.2 Supported tools
The RXB Konnex controllers can be commissioned either with the Konnex tool ETS3 Professional, the Synco ACS Service too or the HandyTool.
Be careful when using different tools. The following rule applies: Last one's right!
When you use an OCI700 as the interface, connect it to the controller's or room unit's service socket. The OCI700 must be powered via USB by the computer as long as it is connected to the service socket. Otherwise, the LCD display for the room device goes dark and the controller goes to addressing mode.

2.7 Test the periphery using room unit QAX34.3
This function requires a QAX34.3 with index D or higher!
The HandyTool allows you to test the connected field devices (sensors, actuators). This works only for the controller connected to the HandyTool; master/slave operation is not possible. An application must be selected and fully parameterized in the controller (address and zones can contain default values). Start parameterization mode:
Press buttons < , > and – simultaneously for about 2 s until the display turns dark. Release the buttons. Press button – twice briefly. Press buttons + and – simultaneously for approx. 2 s The display goes dark. Press button + twice briefly. The display now shows 0 (mode 0).
Use + and / or – to choose between the following modes:
0 = Normal mode (normal room unit functions). 1 = Test mode 2 = Display mode (see 2.5.2). 3 = Parameterization mode (see 2.5.2). 4 = Upload (see 2.6). 5 = Download (see 2.6). 6 = Service mode. The following positions can be selected depending on the type of parameterization. They are displayed with prefix "T". The list shows all theoretically possible positions. However, only positions that are available for selection based on the type of parameterization are displayed.
Theoretically possible positions for periphery testing:
T 01 Sensor input B1 9) Value of B1 in °C.
T 11 Digital input D1 9) True state of the contact at D1 (0 = open; 1 = closed).
T 12 Digital input D2 9) True state of the contact at D2 (0 = open; 1 = closed).

3 Select communications mode
Section 1 shows that RXB room controllers can work in both S- and LTE mode. They are used in S-mode when networked with the DESIGO automation and control system, and in LTE mode with Synco. The factory setting of all controllers and the basic setting of the tools is 0 = S-Mode. This minimizes the bus load. Exception: ACS Service changes the setting immediately to 1 = LTE + S. The ETS3 Professional is used in DESIGO networks. It can be used for operation in
– S-mode. – LTE-mode and S-mode.
The send heartbeat and receive timeout are described in section 10.1.

3.1 Address zones in LTE mode (together with Synco)
This section applies only to LTE mode.
Zone addresses must be allocated in cases where RXB Konnex controllers are used in LTE mode (e.g. together with Synco). These must be defined together with the Synco devices at the planning stage.
The zones to be defined are:
Geographical zone (Apartment . Room . Subzone) Apartment = ---, 1...126 Room = ---, 0...63 Subzone = ---, 0...15
Zone in which an RXB Konnex controller is located. Other room-specific devices may also be located in this zone.
The designations "Apartment, Room and Subzone do not need to be taken literally. For example, Apartment can be used to refer to a group of rooms, floor, or section of a building. Room, however, really does refer to a room.. Subzone is unlikely to be used much for HVAC devices – it is more relevant to other disciplines such as lighting (keep the setting 1).
Time switch zone
(Apartment . Room . Subzone) Apartment = ---, 1...126 Room = ---, 0...63 Subzone = ---, 0...15
This zone has the same structure as the geographical zone. It indicates the source of the schedule for the RXB Konnex controllers. The same zone must also contain a device to provide the schedule (e.g. a Synco RMx7xx or RMB795).
In a Synco network, Room and Subzone must always be set to 1.
Refrig distr zone cooling surface
Zone = ---, 1...31
Chilled water-specific information of a chilled ceiling is exchanged within this zone (e.g. cooling demand). This zone also includes a Synco device to process the information (e.g. RMU7xx or RMB7xx).
Heat distr zone heating surface
Zone = ---, 1...31
Hot water-specific information of a radiator is exchanged within this zone (e.g. heating demand). This zone also includes a Synco device to process the information (e.g. RMU7xx or RMB7xx).

The outside temperature is exchanged in this zone (all Synco 700 devices).
Master/slave zone
(Apartment . Room . Subzone) Apartment = ---, 1...126 Room = ---, 0...63 Subzone = ---, 0...15
In cases where RXB controllers are to be operated in master/slave mode, a master/slave zone must also be defined. For the master, it is usual to enter the geographical zone of the master. The same master/slave zone is used for the slave as for the master.

The zones are defined under Communication.
Individual zones can also be disabled via command if they are not being used. This has the advantage of reducing the load on the bus.

3.2 RXB application example with RMB795 for geographical and time switch zones
The room group philosophy is applied to the following example. This example uses FNC applications. CLC and RAD applications, however, apply the same principle.
The building has three stories used by different companies for their headquarters. The following companies rent offices on the third floor:
– Company Sport AG with conference room and two offices. – Company Logistics GmbH with 6 offices and 1 meeting room.
Each of the two companies wants to operate their room groups at different operating modes, i.e. with the following separate items: – Schedules. – Setpoints. – Fire and smoke extraction functions.
The following example shows the rooms on the third floor for the two companies Logistiics Ltd and Sport Ltd:

D = Device address, G = Geographical zone (Apartment . Room . Subzone).
On the KNX bus, several rooms are summarized in a room group via geographical zone addressing. This address comprises three parts:
Geographical zone: Apartment . Room . Subzone (e.g. 2 . 1 . 1)
A geographical zone must be assigned:
– To each RXB room controller. – To each room group of the RMB795 control station. Here, all devices to be part of the same room group must have the same apartment number. The RMB795 control unit only allows for setting the room group, i.e. the geographical zone (apartment).

The room and subzone are fixed (room = 1, subzone = 1).
To set the room group at the control unit, the following applies: Room group = Geographical zone (apartment . 1 . 1).
The following settings are available in the RXB room controllers:
– Geographical zone (apartment). – Geographical zone (room). – Geographical zone (subzone). For HVAC applications with RXB room controllers, use only the geographical zone (apartment) and the geographical zone (room).
Extending the address by the geographical zone (room) results in room control by means of RXB room controllers. This in turn allows for individual operating interventions (from an operator unit and the control unit via the bus) such as room setpoint correction in any room or on any device.
For additional division of the geographical zone (room), the RXB room controller offers the geographical zone (subzone). This subzone can be meaningful in lighting installations, e.g. if a geographical zone (room) must be subdivided into two subzones "lighting along window" and "lighting along hallway". For HVAC applications, keep the subzone at = 1.
The supplementary labels "apartment", "room" and "subzone" are predefined by Konnex. However, apartment does necessarily denote an actual apartment. Each KNX member requires an individual device address, entered in the floor plan above with D:11x. The device address in our example was assigned based on the bus topology.

5 Room operating modes 5.1 Description
The operating modes in DESIGO RXB are Comfort, Precomfort, Economy and Protection. In addition, the controller has a frost Protection limit, at which an alarm can be triggered. Each room operating mode has separately adjustable heating and cooling sequence setpoints.
Heating Cooling Y [%]

85D
01
Comfort Precomfort Economy Protection Frost risk
Y Output signal (valve or damper actuator). TR Room temperature.
Comfort is the room operating mode in an occupied room. The room temperature is within the Comfort range. The room controller operates in the heating or cooling sequence with the resultant Comfort setpoints. In Precomfort room operating mode (in an unoccupied room), control uses setpoints that are slightly under the Comfort setpoint for heating and slightly above for cooling.
Comment: Since Standby is used in standardization specifically for boiler standby, we now use the term Precomfort for the room operating mode. (Exception: The switching state in the schedule room occupancy is still referred to as Standby). If a room is unoccupied for an extended period of time (e.g. night setpoint via schedules, see pages 35, 47, 57), energy supply to the room can be reduced significantly. In the Economy room operating mode, control uses setpoints that are slightly under the Precomfort setpoint for heating and slightly above for cooling. If the building is unoccupied over an extended period of time (e.g. vacation), the temperature setpoints can be reduced or raised so that the building and all equipment are protected against heat or cold at any time. If the room temperature drops below the risk of frost limit value, an alarm is triggered that can be further proceeds in the building automation and control system. The room controller continues to operate at the relevant setpoint (e.g. Protection, Economy, etc.). The alarm value in the controller is set to 5 °C.

If a window is opened, the room controller always switches to room operating mode Protection, i.e. the heating or cooling output is reduced to a minimum. If a window is opened outside the building-in-use period, it is possible to, e.g., trigger an additional alarm in the building automation and control system.
The table below shows the Effective room operating mode as a function of the window contact input. Window contact status

Window closed No effect. Lower-priority inputs determine the operating mode.

The window contact is connected directly to a digital input on the room controller (see page 102). Alternatively an EIB/KNX window contact (connected to the bus) may be used. The application evaluates both items of information (logic OR operation). Since EIB/KNX window contacts are available from a variety of manufacturers, the name of the S-mode output communication object varies accordingly.

This schedule determines the overall period of time for which the entire building is in use. Typically, it is used for night setback throughout the building or for long periods when the building is not in use.
When the building is not used, interventions of third priority are disabled. This prevents demand signals from being sent to the primary plant when e.g. a security guard enters a room.
The table below shows the three possible occupancy states and the resulting Effective room operating mode.
Switching state Description Effective room operating mode
Building in use Full availability of all plants. Building enabled for use. Priority 3 influences are enabled (schedule
occupancy, presence detector, room unit, and Temporary Comfort mode).
According to schedule occupancy, presence detector, or room unit
Building not in use Reduced availability of the plants. Priority 3 influences are disabled (schedule
occupancy, presence detector, room unit, and Temporary Comfort mode).
Application: For temporary vacancy. The building must reach the Comfort temperature within hours.

The Effective occupancy is determined by the occupancy schedule and the presence detector. It controls the room operating mode of a room controller while the building is in use.
The central time schedule transmits the anticipated occupancy of a room or group of rooms. It controls the room operating mode of a room controller while the building is in use. Outside the building-in-use period, the time schedule is disabled.
The time schedule can be used, e.g. by a building tenant to specify occupancy times of his or her rooms.
The occupancy schedule has three possible states:
State Description
Occupied Occupancy expected. Room controller switches to Comfort.
Standby Occupancy is probable; the room must be ready for use shortly (Comfort temperature).
Room controller switches to Precomfort.
Unoccupied No occupancy expected. Room controller switches to Economy.
A presence detector detects the presence of people in a room.
It controls the room operating mode of a room controller while the building is in use. Outside the building-in-use period, it is disabled.

5.3.8 DESIGO examples
The following examples show two typical applications of schedules and local control of the room operating mode. Rooms without room unit or presence detector
The room operating mode of rooms 1…3 in a building is determined by the two schedules Use and Occupancy. Window contacts are installed in all rooms.
The following conditions are specified:
The building is in use from 06.00 to 22.00 (Use schedule). Outside this period the opening of a window trips an alarm (2).
Rooms 1 ... 3 are used by the same tenant and are controlled by the common schedule occupancy: Night setback is between 17.00 to 8.00 (not occupied), lunch between 12.00 and 13.00 (standby).
In Room 3, the window is opened briefly once in the morning and once at night (1).

Rooms with a room unit ( /Auto button) or presence detector
The room operating mode in rooms 1 and 2 of a building is determined centrally by the Use and Occupancy schedules. The RoomOccupancy schedule defines the period during which both rooms must be available (standby). Comfort room operating mode is then initiated locally via the room unit (room 1) or presence detector (room 2).
The following conditions are specified:
The building is in use from 06.00 to 22.00 (Use schedule). Rooms 1 and 2 must be available from 08.00 to 18.00 (room occupancy schedule:
standby). The occupants of Room 1 continue working in the evening beyond the programmed
occupancy period. At the end of the programmed period of occupancy, the room operating mode changes to Economy even if the room unit is set to Auto (1). Comfort mode can now be reactivated with the Auto switch on the room unit (2). Comfort remains active for the set Temporary Comfort mode period (see page 103). At the end of the building-in-use period, however, the Temporary Comfort mode period is overridden and the room controller returns to Economy mode (3).
Room 2 is occupied in the evening beyond the building-in-use period (4). However, at the end of the building-in-use period, the room operating mode still changes to Economy. An alarm can be triggered if required.

5.4 Determine the room operating mode with third-party products (S-mode)
In S-mode, the Effective room operating mode of the room controller depends on the central Room operating mode schedule and/or on local influences such as window contact, presence detector, or room unit.

5.4.8 Third-party (S-mode) examples
The following examples show two typical applications of schedules and local control of the room operating mode. Rooms without room unit or presence detector
The room operating mode in Rooms 1..3 of a building is determined by the room operating mode schedule. Window contacts are installed in all rooms.
The following conditions are specified:
Overall, the building is in use from 06.00 to 20.00. The rooms are used and controlled by the room operating mode schedule as follows:
– Night setback from 17.00 to 08.00, – Protection from 20.00 to 06.00 – Lunch from 12.00 to 13.00 (Precomfort).
In Room 3, the window is opened briefly once in the morning and once at night (1).

The following conditions are specified:
The building is in use from 06.00 to 20.00 (Protection from 20.00 to 06.00).
Rooms 1 and 2 must be available from 08.00 to 18.00 (Precomfort). The occupant(s) of room 1 are working overtime. At 18.00, the room operating mode
changes to Economy, even if the room unit is set to Auto (1). Comfort mode can now be reactivated with the Auto switch on the room unit (2). Comfort remains active for the set Temporary Comfort mode period (see page 103). In Protection mode, however, the Temporary Comfort period is also overridden and the room operating mode changes to Protection (3).
Room 2 is occupied in the evening beyond the building-in-use period (4). However, at the end of the building-in-use period, the room operating mode still changes to Protection. An alarm can be triggered if required.

5.5 Determine the room operating mode with Synco (LTE mode)
In LTE-mode, the Effective room operating mode of the room controller depends on the central room operating mode schedule and/or on local influences such as window contact, presence detector, or room unit.

If the room operating mode in the ACS (operating booklet) is AUTO, the priorities
1 to 3 apply. If the room operating mode in the ACS (operating booklet) is Comfort, Precomfort, Economy or Protection, these modes have absolute priority ("Prio 0").
The effects of Priority 1 and Priority 2 are similar in nature to states, which apply continuously
The influence of priority 3 is treated as event. The key point in time is the moment at which the state changes (edge). If another source of third priority later changes the state, the last known change is valid.

If the window is opened (1), the room operating mode changes to Protection and the room unit is switched again to .
Room 1 has a room unit.
As no presence detector is connected, the basic room operating mode is Precomfort and the timer (Temporary Comfort mode time, see page 103) is thus not available. The room unit allows for switching between Precomfort and Comfort (2).
Room 2 has a room unit and a presence detector.
If unoccupied, the basic room operating mode is Economy; if occupied, the room operating mode changes to Comfort (3) and the room unit is set to Auto. The room unit allows for switching between Comfort and Precomfort (2).
Room 3: To force the basic room operating mode Economy, a presence detector in
state unoccupied is simulated at an open digital input (occupied = contact closed, see page 102). The timer is available from Economy. The room has a room unit on which the timer is activated (Temporary Comfort mode period: see page 103). This is where the room operating mode is set to Comfort (2); when the window is opened (3), after timer expiration (4), or after pressing again the /Auto button (5), the room operating mode returns to Economy.

6 Setpoint calculation 6.1 Description
Each room controller knows 9 different room temperature setpoints: One heating and cooling setpoint each for the room operating modes Comfort, Precomfort, Economy, and Protection as well as Frost risk limit value.
The setpoints are: – Defined in the tool during engineering. – Adjusted during runtime by the communication objects (DESIGO, Synco).
This does not apply to Protection setpoints and Risk of frost limit values (page 31).
The setpoints are shifted: – Centrally via KNX bus from the building automation and control system
(only Comfort, Precomfort and Economy). – Locally via PPS2 by a room unit or a setpoint adjustment unit
(only Comfort and Precomfort). – The controller controls the values internally to ensure that sensible periods are
adhered to between the various room operating modes. The result are 8 present setpoints.
The Effective room operating mode selects one value each for heating and cooling from the 8 setpoints. These are the effective setpoints used by the controller.

HandyTool: If setpoints are irrelevant for the application (e.g. heating setpoints for chilled ceiling), they are hidden, and they are set equal to the Protection setpoints internally. For reasons of symmetry, all communication objects are always available.
6.3 Setpoint setting runtime
The setpoints are stored in the EEPROM so that they are retained upon a reset. If the communication objects Setpoints heating and Setpoints cooling receive a value different from the previous value, this is written to the EEPROM. The service life of the EEPROM depends on the number of write cycles.
The setpoints for Comfort, Precomfort, and Economy, for heating and cooling each, can also be defined during runtime as individual values or triplets via the bus.

6.4 Central setpoint shift
The Comfort, Economy and Precomfort setpoints can be adjusted separately for heating and cooling centrally from the BACS. Central setpoint shifts are used particularly e.g. for summer/winter compensation. Summer/winter compensation causes a gradual increase in room temperature as a function of the outside temperature. This prevents too great a difference between the indoor and outdoor temperature in summer and increases overall comfort in winter. Normally, only Comfort and Precomfort values are shifted. The room controller corrects the setpoints resulting from central shift by applying the following rules Comfort setpoints:
The value for the spacing must not be below the original value A .
Precomfort setpoints: The value for the spacing to Comfort setpoints must not be below the original values B .

7 Temperature measurement 7.1 Room temperature measurement
The value valid for temperature control can originate in various sources: – A room unit via PPS2 7.1.1 – An analog sensor via analog input B1 7.1.2 – Mean value of several sensors 7.1.3 – The bus. 7.1.6 If none of these sources supplies a valid room temperature, the following will happen: the controller uses the mean value from the effective heating and cooling setpoints
for control until a valid measured value is again received the controller issues an alarm "Room temp. sensor error" the bus output sends 0°C if slaves are connected, they receive an invalid temperatur (327.67°C) if a room unit is connected to a slave, the slave uses the temperature value of its
room unit when two heartbeat periods have elapsed.

If both a QAX3… room unit and a QAA24 LG-Ni1000 sensor are connected to a controller, the measured room temperature is automatically based on the average value from both sensors. Automatic detection prevents miscalculation. A QAX34 / QAX84 will display this average value.

8 Control sequences 8.1 Radiator (RAD01)
The radiator application has a continuous heating sequence. The room controllers operate with a PI algorithm optimized for thermal or motorized valve actuators. (For simplicity, the diagram below only shows the P-control action.)
This application can also be used for other heating types, e.g. floor heating. However, the control parameters are not optimized for this.
The control sequences come into operation at the effective setpoints for heating and cooling (see page 67).

8.1.1 Actuator type selection
All actuators have threads suitable for fitting to both normally-closed (push to open) and normally-open (pull-to-open) valves. However, the RX applications do not support inverse control, which means that only actuators with a pulling action can be used with "pull-to-open" valves and only actuators with a pushing action can be used with "push-to-open" valves. This is why, in RX applications, valves with mounted actuators are always closed when de-energized. Different valve types are available for selection for the radiator:
– Thermal actuators are controlled by an AC 24 V PDM signal. – Motorized actuators are controlled by an AC 24 V 3- point signal. – Electromechanical actuators (motors with spring return) have a special PDM
algorithm that ensures that 50 position changes per day are not exceeded. This causes a slower control behavior.
Thermal and electromechanical actuators, therefore, require one output while motorized actuators require two. The table below shows the possible combinations:

The RXB2… room controllers also support the use of motorized EIB/KNX bus actuators. In the tool, select Motoric bus. If thermal actuators are selected, Y1 / Y2 are always controlled in parallel to ensure
that several actuators can be connected at the same time. It is not possible to ensure exact parallel running of more than one thermal valve
actuator. If several radiators are controlled by the same room controller, preference should be given to motorized actuators. If thermal actuators must nevertheless be controlled in parallel, third-party thermal must be parameterized regardless of manufacture. This applies also if an external power amplifier is used to drive the actuators.
Thermal actuators operate at a raised temperature. To ensure a fast response, the actuators are continuously preheated to a slightly higher temperature (5% – 1 s ON / 19 s OFF). They therefore continue to receive pulses from the controller even when closed.
Möhlenhoff actuators have been tested successfully in our HVAC laboratory. Electromechanic third-party devices often have different runtimes for opening and closure. For optimal control, the longer of the two runtimes must thus be parameterized. When switching on the controller, after parameterization, after switching from test mode to normal mode and for valve protection (unblocking, see page 84), the actuators are synchronized:
Thermal heating and cooling valve actuators are controlled for 5 minutes with open (50% – 1 s ON/ 1 s OFF), then for 5 minutes with close" (5% – 1 s ON/ 19 s OFF).
Motorized actuators are opened first (110% runtime) and then closed (110% runtime).

With motorized actuators (conventional and bus actuators), third-party devices can also be connected. The actuator running time can be adapted and an offset set accordingly.

For electromechanic actuators, the actuator running time can be adapted.

8.1.5 Downdraft compensation
This function is only active in Comfort mode.
In situations where (owing to large internal heat gains) there is no heating demand from the room despite a low outdoor temperature (supplied via bus), large window surfaces can impair indoor comfort (through radiated cold, downward flow of cold air, condensation). A radiator located under the window can be used to slow the downward flow of cold air and compensate for cold radiation.
To achieve this, the radiator is switched on whenever the outdoor temperature drops below a predefined value (the outside temperature 0% valve position).
The maximum heating output (set under Max. valve position) is reached at the coldest outdoor temperature (which can be set under Max. outdoor temperature valve position).

The controller adds the values representing the valve position for downdraft compensation and the valve position for the heating sequence. – If the room temperature rises as a result of the downdraft compensation feature, the
heating sequence reduces the opening of the associated valve, so correcting the room temperature.
– When the sequence reaches zero, the room temperature is increased by the residual heat from the downdraft compensation feature.
The heat output calculated by the controller is achieved as follows:
LTHW radiators with motorized valve actuators
The valve is opened to the heat output value [%].
LTHW radiators with thermal valve actuators
The minimum heat output is 25% (LED08: 10%): 400 seconds "OPEN" (1s On, 1 s Off) 1200 s "CLOSE" (1s On, 19 s Off)
Heat output 50%: 400 seconds "OPEN" (1s On, 1 s Off) 400 s "CLOSE" (1s On, 19 s Off)
Heat output 80%: 1600 seconds "OPEN" (1s On, 1 s Off) 400 s "CLOSE" (1s On, 19 s Off)
The long cycle time ensures that the valves are fully opened and closed.
In a network containing several room controllers, the opening of the Siemens thermic actuators is staggered to prevent the heating load from fluctuating.
If a thermal radiator valve actuator and a thermal heating/cooling valve actuator work in parallel, the controller controls them alternately.

Before the valve actuators can be overridden, Test mode must be activated via the communication object Application mode (see page 105).
8.2.5 Dewpoint monitoring
Dewpoint monitoring is essential to prevent condensation on the chilled ceiling and the associated damage to the building.
DESIGO RXB provides passive dewpoint monitoring. If condensation occurs, the cooling valve is fully closed until no further condensation is detected. The cooling output is thus temporarily disabled. However, the room controller remains in its effective room operating mode.
The example below shows central dewpoint monitoring combined with passive dewpoint monitoring provided by the DESIGO RXB controller. The flow temperature is increased in accordance with a centrally calculated dewpoint temperature. If the dewpoint temperature in the room exceeds the flow temperature, condensation forms and the cooling valve closes.

8.2.6 Central/passive dewpoint monitoring
The dewpoint can be monitored in two ways: – A dewpoint sensor with a potential-free contact is connected directly to a digital input
of the room controller (see page 102). – Dewpoint sensor via bus. The two inputs are OR-linked: If one is active, dewpoint alarm applies.

For dewpoint monitoring, a logic OR operation is applied to the locally connected
sensor and the bus sensor. The result is used in the alarm object room dewpoint alarm output on the bus (see
10.13). When parameterizing, note whether the contacts are NO or NC (see page 102). Note the following for master/slave configurations:
– Dewpoint sensor on master: The sensor is evaluated locally cooling valve closes. This information is transmitted to the slaves.
– Dewpoint sensor on slave: The sensor is evaluated locally cooling valve closes. This information is NOT transmitted to the master and further slaves..
The controller immediately queries the dewpoint alarm input following a reset (if configured accordingly and provided a dewpoint is integrated).

Example for master/slave: Several controllers are installed in a large, open-floor office.
One controller (master) measures the room temperature and controls the other controllers (slaves) via the KNX bus. This ensures that future subdivision of the room into smaller rooms without the need to change the wiring is possible.

Master Slave Slave
Room 321 Room 322 Room 323
Controller A is configured as the master and controls the room temperature. Controllers B are configured as slaves and operate in parallel with controller A.
A slave controller may be controlled by one master controller only. A master,
however, can control any number of slaves subject to the limits of the KNX system (topology, bus load etc.).
Parallel operation of thermal valves among other factors primarily depends on the supplied voltage. We recommend to parameterize "3rd Party Thermic" for thermal valves regardless of make.
Master-slave bindings are possible only between same-version controllers (ASN) featuring the same applications and settings.
Parameter Description
Master Normal control.
Slave The slave controller is controlled by a master controller via the KNX bus. The master and slave controllers operate in parallel. The room temperature is measured only by the master.

10.1 Send heartbeat and Receive timeout
In a KNX network, S-mode and LTE mode communication objects can be exchanged between individual devices. The receive timeout defines the period of time within which all communication objects of a device must be received at least once. If a communication object is not received within this period, a predefined value is used and an error message generated. This ensures that interruptions in communication are identified at an early stage.
Similarly, send heartbeat defines the period of time within which all requested communication objects must be transmitted at least once.
The time intervals are based on the size of the network. Normally the basic setting can be retained. In the case of S-mode communication objects, shorter times may be selected for smaller networks or for test purposes. The receive timeout must always be longer than the send heartbeat. Parameter Basic setting Range Resolution
Receive timeout 60 min 0 ... 105 min 5 min

10.10 Test mode (Test, 7)
The following override functions are used to commission the controller and for service purposes, e.g. to test a valve actuator. The controller must first be switched to HVAC test mode by transmitting the value 7 =TEST via Application mode. To exit test mode, send first Application mode = 6, OFF and then = 0, AUTO. In test mode, valve actuators can be se to defined values via KNX bus signals. A soft reset is carried out after the controller exits test mode:
Motorized valve actuators and dampers are synchronized. Thermal valves are synchronized. The control algorithm but not the entire application is restarted. Test mode is available only for S-mode objects!
10.11 Emergency heat (8)
This function is used for emergency heating when the room temperature drops below the Risk of frost limit value. The function depends on the Effective room operating mode.
The function affects control of all installed heating aggregates.
When using a radiator and a heated ceiling the valve opens fully. An electric radiator is switched to the highest stage and is maintained there until the temperature rises above the Protection heating setpoint again.
When the room temperature rises above the Protection setpoint, the controller reverts to the original application mode (see page 105).

Enable alarm info can also be operated in LTE mode. Here, two types of information are provided: AlarmInfo_CS and AlarmText_CS. With Synco, the user does not need to deal with this, as connection is opened automatically.
The device in this case is active on the bus and sends its alarm as soon as it receives highest alarm priority. This ensures that the control station does not miss alarms.

10.14 Reset setpoint shift
When the system changes from Comfort or Precomfort to Economy or Protection, the setpoint shift can be reset (see page 72). This function can be enabled and disabled via Central functions. The setpoint shift can only be reset with the QAX34.1 and QAX84.1 room units, which have an LCD display. Enabling this function in room units with a mechanical setpoint shift (potentiometer) causes data transmission errors.

12 KNX information 12.1 Reset and startup response
A reset is initiated under the following circumstances:
Failure of the processor (e.g. watchdog). After a power failure. After a bus power failure. Upon completion of a self test (using communication object Status request). Via ETS (without startup delay)
– After downloading the physical address – After downloading the parameters – Via ETS (menu Commissioning, Reset).
After parameterization in ACS. After exiting Parameterization mode in the HandyTool. After Test with the HandyTool The application is restarted after every reset. Depending on the controller address, this may take 1 ... 255 s.
Then, the bus connection is opened and all connected valve actuators are synchronized. This takes the following time depending on application and actuator type:
Typically 170 s for closing (runtime + 10%) for motorized actuators.
300 s ON and 300 s OFF (3rd party: 400 + 400 s) for thermal actuators. The application is placed in a safe state. Any outputs that are not synchronized are not operated (triac outputs = 0, and relay = open). Normal operation is resumed after synchronization. When the controller exits test mode, only a soft reset is carried out: – Valve actuators are synchronized. – The control algorithm but not the entire application is restarted. Each time the control sequence reaches 0% or 100%, a limit position
synchronization takes place. – For motorized actuators close or open during (runtime + 10%). – 300 s ON and 300 s OFF (3rd party: 400 s) for thermal actuators.
12.2 LED flashing pattern
An LED is located at the controller's bottom right indicating the operating state by various flashing patterns:
Green, flashing Normal operation. Red, flashing Programming mode for address assignment (ETS3 / ACS). Orange / green, flashing
Startup phase (see above 12.1). No application selected (see 4.1). Loading. – Download from ETS3 or ACS. – Room unit QAX34.3 in HandyTool mode.
Other patterns After switching on the operating voltage, the controller flashes for 3 to 5 seconds in different patterns. If other patterns appear during normal operation, this indicates an error.

12.3 Startup delay
After a reset, it takes up to 5 minutes for all connected room controllers to restart. This is designed to avoid overloading the mains power supply at startup. At the same time, it reduces the load on the KNX network, as not all controllers transmit data at the same time.
The delay is determined by the device address of the controller.
12.4 Bus load
In a large KNX system, bus load can be a problem especially with central commands which cause the controllers to send state information simultaneously. This can even result in the loss of data telegrams.
The management station is normally connected to the KNX bus via the area line. This line thus requires special attention on bus load, as it can become the system’s bottleneck: The bus load acceptable on individual lines results in overload on the main lines and area line.
To avoid a KNX communications overload, note the following rules and precautions:
Define a rational topology, divided into lines and areas. Avoid cross-line functions: place sensor and actuators on the same line if possible. Load filter tables for the line and area couplers so that local information does not
burden the entire system. Meaningful integration in management station or visualization: Integrate only
information that is really required. For state messages, automatic transmission is not necessary if the display device
can actively read the values. The flags must be set accordingly in the ETS. Do not define too short an interval between heartbeats. Divide central commands which affect a large number of controllers over several
group addresses, and stagger transmission. Each group address must have a recipient to acknowledge the telegram, otherwise
unwanted repeat-telegrams are generated. Further notes on reducing bus load, see pages 23 and 83.

13 FAQ
What happens if the parameter download process is interrupted? (power failure, bus failure etc.) The parameter set loaded into the controller is incomplete. The controller does not start properly. Valves may not open. Reload the parameters. Why does the controller fail to start after a parameter download? (applies to HandyTool, ACS or ETS.) Parameter download was probably interrupted or exposed to interference. Reload the controller with the entire parameter set (via HandyTool, ACS or ETS). Why does the controller not start after adjusting certain parameters? (applies to HandyTool.) Parameter download probably interrupted or fault, or controller unloaded via ETS. A complete parameter set must be loaded in the controller (via HandyTool, ACS or ETS). Why does the HandyTool not display parameter 1 upon quick quit and restart of the Display mode? Communication to the HandyTool is relatively slow. You need to wait a brief moment before reopening the Display mode. Why does the HandyTool display "uuuu"? Other parameters have been changed so that the selected parameter became irrele-vant. Just continue your work;. the problem will disappear when the parameterization is started again. ACS: Why is reading back parameters so slow? Check to make sure that neither the operating booklet nor the plant image is active. Both applications cause a lot of bus traffic and thus slow down reading back parameters. ACS: CLC01 shows the lower limit of 21°C for the Comfort cooling setpoint. Setpoint data are only updated when the application (RAD01, CLC01, ...) has been selected.

ACS: Parameter download does not work, why? Make sure that the parameter tree is expanded prior to download.
Wrong Right
Download sometimes also works with a collapsed parameter tree. Why can I not parameterize the controller via HandyTool in service mode (n6)? There are two reasons: Download (HandyTool, ACS or ETS) was not exited correctly (interrupted). The controller was set to "unloaded" via ETS. Solution: Carry out a full download (via HandyTool, ACS or ETS). Why does a controller with thermal valves not respond immediately when it is enabled in the plant graphics in the ACS view and in the DESIGO graphics? After startup, the thermal valves are preheated first. This is not shown in the plant graphic. Why doesn’t the Master/Slave connection work? Master/slave zones must match for master and slave Create master/slave group addresses and add communication object. With master/slave configurations, why do the QAX34 room units not always show the same temperature values? The master-controller and slave-controller data is synchronized regularly. If a value changes just after synchronization, it may be a few minutes until it is resynchronized.

Why does the slave window contact/occupancy contact have no effect? The slave window contact can only be integrated via the CFC. The corresponding compound is available on Swan Web: [WndStaDtr], [OcStaDtr]. For one slave controller: Create group addresses for window contact and add communication object of master and slave. For one ore several slave controllers: In CFC by means of compound [WndStaDtr], [OcStaDtr]. Why does the ACS plant graphic not always display all values (e.g. room operating mode)? The controller is configured as a slave. These values are not available with slave controllers. Why doesn’t the ACS operator book show the current data? After a change of application (e.g. from FNC12 to FNC18), you must update the reference data points. ACS: CLC01 shows the lower limit of 21°C for the Comfort cooling setpoint. Setpoint data are only updated when the application (RAD01, CLC01, ...) has been selected. Why doesn't an RXB controller transmit S-Mode communication objects that it has received? RXB controller do not work as bus relays. If a communication object is required, the binding must be to the source, not to the RXB controller. Example: an RXB controller receives the room temperature from a bus sensor. A bus display is used to display the room temperature. The display must get the signal directly from the bus sensor.

15 Working with different tools
It is possible to prepare the RXB controllers in the office (parameterize in advance) so that only the physical address has to be entered on site. To this end, the HandyTool offers its “small parameterization”. In this case, preparatory work is probably carried out with ACS or ETS rather than the HandyTool. Special caution is required (data consistency) when using more than one tool.
First step Second step
