1 Notes on the documentation

The following pointers are a guideline for the

whole documentation.

This manual is to be stored in the vicinity of the

heat pump and must be easily accessible.

1.1 Symbols The precautionary pointers below will be

used in this document.

WARNING

Pointer which, if not heeded, can mean

danger to life and limb, and can also lead

to material damage. These pointers must

be heeded without fail.

ATTENTION

Pointer which, if not heeded, can lead to an

appliance malfunction and to material dam-

age (to system components, building, ...).

These pointers must be heeded without fail.

2 Safety instructions

Read this manual carefully before you begin to com-

mission/adjust the heat pump!

Converting or altering the appliance is

not allowed. Work on the appliance (re-

pairs, alterations) may only be carried

out by the manufacturer or by a special-

ist authorised by the manufacturer.

All circuit breakers in the heating sys-

tem are to be turned off before any

work is carried out on the terminal

strips or electrical

connections (wiring). The heating sys-

tem consists of the control, the auxilia-

ry modules and the components that

are connected to the control (heat gen-

erator, pumps, safety thermostats, etc.)

Contact with the terminal strips, wires

connected to them, or non-connected

wires by persons or by means of elec-

trically conductive

materials is prohibited as the terminals

strips could be live (danger of touching

power supply).

The control, auxiliary modules, terminal

strips and wiring of the

control can also be supplied with line

voltage by external switching (safety

thermostats, etc.), even if the control is

not connected or is receiving no power

The commissioning as well as the ser-

vicing of the appliances may only be car-

ried out by personnel which are authorised

by OCHSNER.

The installation of the appliances and

their electrical wiring may only be car-

ried out by a specialist according to lo-

cal regulations and codes of practice.

Protective functions for the heat pump can

be activated by the control. However, as

the control is not certified as a safety ap-

pliance, the protection against failure or

damage to the heat pump must be

adapted to the local instructions (for in-

stance, by additional external switching of

the safety appliances used.

In the event of Upgrades/Updates to the

control software, all parametered

heat pump functions are to be controlled

once again.

2.1 CE Labelling

The product you have purchased conforms to the

technical regulations valid at the time of manufacture,

and is CE-conform.


3 Description of the appliance

3.1 Heat pump OLWI

The appliance is an air/water heat pump which oper-

ates as a heat pump for heating purposes. The appli-

ance extracts heat at a low temperature from the out-

side air and emits it at a higher temperature to the

water in the heating system.

The water for heating can be heated to a flow tempera-

ture of up to 60 °C.

The appliance has an electrical emergency/auxiliary

heater (DAE) with 8.8 kW rating. In the monovalent

mode, the electrical emergency/auxiliary heater is

activated as soon as the temperature falls below the

bivalent point, so that the heating operation and hot

water heating is guaranteed. In the mono-energetic

operation, the electrical emergency/auxiliary heater is

activated as an auxiliary heater.

Further properties

- Suitable for under-floor and radiator heating

- Low-temperature heating systems are preferred.

- Heat can be extracted down to -20°C outside air

temperature

- The external cladding is of corrosion-protected,

galvanised steel plate with additional stove enam-

elling.

- All components and safety equipment necessary

for operation are built in to the appliance.

- Contains non-flammable safety refrigerant

If the heat pump is to be installed in the proximity of the sea, ensure that a distance >2km is maintained between the sea and the place of installation!

3.2 Function

The heat from the outside air is extracted by means of

an air heat exchanger (evaporator). The refrigerant

vaporises and is then compressed by means of the

compressor. Electrical energy is necessary for this.

The refrigerant is now at a higher temperature level

and transfers the heat from the air via a further heat

exchanger (condenser) to the heating system. The

refrigerant expands and the process begins again.

At air temperatures below ca. +7 °C, the humidity in

the air forms icing on the evaporator fins. This icing is

automatically thawed. The water formed by de-icing is

collected in a thawing sump and drained away by

means of a hose.

The fan switches off during the de-icing phase and the

heat pump circuit is reversed. The heat required for de-

icing is extracted from

the buffer storage tank or heating circuit. At the end of

the de-icing phase the heat pump switches automati-

cally back to the heating circuit

4 Preparation

4.1 Noise emission

The appliance is louder on its air-inlet and air-outlet

sides than on both closed sides. Take the following

pointers into consideration when selecting the place of

installation:

► Installation on beamed roofs is not permitted.

► Do not place the appliance directly under or beside

living or bedrooms.

► Make sure that the air inlet and outlet openings in

the outside walls are not pointed at living room or

bedroom adjacent windows.

► We recommend placing the heat pump on suitable

rubber matting in the event of reverberating bases

such as tiling.

► A more suitable noise reduction can be achieved

with a concrete foundation plate with rubber mat-

ting.

► Pipework conduits through walls and ceilings must

be noise insulated.

► Our heat pumps are distinguished by their especial-

ly quiet operation. Incorrect integration by the instal-

lation can, however, lead to undesired increase in

the sound level under unfavourable circumstances.

NOTE:

You can find information on the sound

power level in the "Technical Data / Data

Table" section.

4.2 Air ducting

► Short circuiting between air inlet and outlet must be

avoided in all events.

► It is practical to construct the ducting across a cor-

ner.

► If necessary, a separating wall or suitable plants

should be placed between air inlet and outlet.

► The weather and/or bird protection grilles should be

easily removed for cleaning.

► The hose length on the suction and exhaust sides

must not exceed 8m. Do not make more than four

90° bends. The bending radius must be at least

600mm, based on the hose middle.

► Due to its flexibility, the hose tends to sag and must

therefore be fixed at ca. 1m intervals.

► The ducting of the air inlet and air outlet to and from

the appliance takes place by means of special air

hoses. These are highly flexible, heat insulated and

are self-extinguishing.

Fig.1: Cross-corner air ducting without a shaft

Fig.2: Cross-corner air ducting with a shaft

Fig.3: Air ducting on an external wall


4.3 Minimum clearances

Dimensions in mm

Fig.4: Minimum clearances inside installation

► Adhere to the minimum clearances in order to en-

sure a trouble-free operation and to allow service

work to be carried out.

Appliance and environmental damage

Make sure that the outside air can enter

and exit the appliance freely without hin-

drance

Should the air inlet and outlet be hindered, a thermal

short circuit could occur.


The minimum air flow rate of the appliance

must be maintained at all times. Should the

air flow fall below the minimum, a trouble-

free operation cannot be guaranteed.

► Ensure that the minimum air flow is maintained.

See the information in the "Technical Data / Data

Table" section.

4.4 Foundation

General

► Make sure that the appliance is accessible from all

sides.

► Make sure that the foundation is horizontal, level,

firm and permanent.

► Ensure that the appliance frame fits uniformly on the foundation Uneven ground can influence the noise level of the heat pump.

4.5 Foundation

1 Concrete base

2 Footfall sound insulation

3 Floating floor screed

4 Floor coating

5 All-round cut-out

Fig.5: Base for inside installation

► De-couple the installation area

Observe the following pointer:

- Construct the pipework fixing and the wall

conduit in a sound-insulated fashion.

NOTE:

Dimension and positioning specifications for the air

inlet and outlet openings as well as the water and

electrical feed through can be found in the Section

"Technical Data / Dimensions and Connections".

4.6 Buffer tank

The use of a buffer tank is necessary in order to guar-

antee a trouble-free heat pump operation.

The buffer tank serves not only as a hydraulic decou-

pling of the water flow in the heat pump and heating

circuits, but also as a source of energy for defrosting.


5 Installation

5.1 Transport

► Be aware of the centre of gravity of the appliance

during transport. The centre of gravity is to be found

in the region of the condenser.

Lifting straps for transporting the basic appliance

can be hooked at any point way to the bottom frame

of the heat pump.

► Protect the appliance during transport from heavy

bumps. If you have to tilt the appliance during

transport, this may only be done for a short time on

the long side. The longer the appliance is tilted, the

more the refrigerant oil is distributed in the system.

► Wait for ca. 30 minutes before you operate the

appliance after it has been tilted.

The appliance must not be placed

on its side!

5.2 Placing and connecting the appli-

ance

NOTE:

- Two screws are provided in the top of the

heat pump frame. These are for fixing the

cowling to the frame.

- Two screws are provided in the bottom of the

heat pump frame, one for each side panel.

► Unscrew the 6 fixing screws in the frame and keep

them for later use.

► Place the appliance on the prepared foundation.

► Pay attention to the direction of the air outlet.

► By fitting the pressure hoses supplied between the

functional unit and the heat pump, no further pres-

sure hoses must be fitted as vibration dampeners.

Air hoses are fitted to the functional module. These

are for connecting the air inlet and outlet openings

in the wall.

► Wall conduits AWG 560H or AWG 560L are to be

used for the wall feed-through.

Installing the functional module:

Fig.6: Installing the functional module:

► Place the functional module on to the heat

pump and fix it with two screws.

► Stick the rating label supplied at the top front

of the right-hand side panel of the functional module so

that it is clearly visible.

Opening the functional module:

Fig.7: Opening the functional module:

► Remove the safety screw.

► Pull the level forward and the left hand flap opens.

► Open the right hand flap by pulling firmly.


Hydraulic connection:

► Connect the functional module to the heat

pump with the pressure hoses supplied.

1 Pressure hose flow

2 Pressure hose return

Fig.8: Hydraulic connection functional module:

► Check the plug connections on the safety

group for firmness and seal.


6 Heating water connection


The 3 electrical circuits for the appliance, the control

wiring and the electric emergency/auxiliary heater must

be protected separately.

► Flush out the system pipework thoroughly before

connecting up the heat pump. Foreign bodies (e.g.

rust, sand or sealant material) influence the opera-

tional safety of the heat pump.

► Connect the heat pump to the heating system.

Make sure all connections are sealed.

► Connect the flexible pressure hoses to their con-

necting sleeves.

The pressure hoses must be at least 1 metre in length.

The low-vibration design of the heat pump and the

flexible hoses, which act as vibration dampeners, pre-

vent the transfer of vibration from the heat pump to the

pipework to a large extent.

6.1 Oxygen diffusion


Avoid open heating systems or steel pipe installations

in connection with diffusion-sealed plastic-pipe under-

floor heating systems.

Diffusion-sealed plastic-pipe underfloor heating sys-

tems or open heating systems in conjunction with steel

pipework can lead to oxygen diffusion corrosion of the

steel pipework.

The products of such corrosion, such as rust silting,

can be deposited on the heat pump condenser and

lead to loss of performance or switching off due to the

restriction in the pipe cross section.

6.2 Second heat generator

In bivalent systems, the heat pump must always be

installed in the return from the external second heat

generator, for instance an oil furnace.

6.3 Filling the heating system

6.3.1 Properties of the water

In order to prevent damage due to scaling, the hard-

ness of the water must be tested before filling the

heating system.

The total hardness of the water must be < 1 °dH (0.18

mmol/l alkaline earths).

► The water must be softened if this value is exceeded.

Filling with prepared water

to VDI 2035 / Ö Standard5195


Desalinated water or rainwater must not be used as

this leads to increased corrosion. Suitable appliances

for softening as well as for filling and flushing the heat-

ing system can be obtained in specialist shops.

6.3.2 Filling

1 Emptying

Fig.9: Filling the heating system

► Filling the heating system via the drain valve.

► After filling the heating system, check the

connections for seal (visual inspection and feel).


6.4 Bleeding the heating system

1 Automatic air-vent

Fig.10: Bleeding the heating system

► Bleed the pipework system carefully

► Operate the automatic air vent on the appliance

6.5 Condensate drain

A condensate drain hose is attached to the de-icing

sump The condensate drain hose is in the compressor

space on delivery.

► Make sure that the condensate hose is not bent.

► Install the hose with a constant slope downwards.

► If the slope is not sufficient, a suitable condensate

pump must be installed Take the constructional fac-

tors into consideration.

► When using a condensate pump, make sure that its

rating is at least 6l/min.

Fig.14: Breakout plate for supply pipework

► Lead the condensate drain hose at an

oblique angle through the hole in the "Durchführung

Versorgungsleitung“ (supply pipework feed through)

► Fix the condensate drain hose in such a way

that it cannot slip.

► Drain the condensate into a drain

6.5.1 Check the condensate drain

After laying the condensate hose, make sure that the

condensate is draining freely. Proceed as follows:

► Pour water onto the evaporator so that it flows into

the de-icing sump. Ensure the maximum conden-

sate flow of 6l/min.

► Check that the water drains away via the conden-

sate drain hose.

6.6 Flow rate measurement The heat use system flow rate sensor is part of the heat pump and must be installed by the system installer according to the

OCHSNER installation instructions.

Please observe the instructions for the adjustment of

the flow rate (see Annex 18.1 - adjustment

of the flow rate).

If the flow rate meter is either not installed, or incorrectly installed, OCHSNER will not undertake the commissioning of the sys-tem.

OCHSNER accepts no liability for possible

damage which may occur if the flow rate

meter is either not installed, incorrectly in-

stalled, sized or wired up.

Fig.15: Flow meter installation in heating system


7 Electrical connection

DANGER of electrocution

Install all electrical connections according

to national and local Standards

The regulations of the responsible energy

utility and the relevant EN-standards are to

be strictly adhered to.

Connecting work may only be carried

out by a certified specialist according

to this instruction!

The heat pump connection must have

been approved by the competent utility

before it is carried out.

The stated voltage must be the same as the house

circuit voltage. Observe the rating label!

The circuit breaker for the main power supply circuit is

to be a 4-pole fuse that switches off all poles in the

event of a malfunction (for currents, see technical data

Pt. 14/). The supply cable must be protected against

overload and short circuiting. The control cable is also

to be protected by means of an all pole circuit breaker

C16A.

The values for the circuit breaker fuses in the Annex

are guideline values only! The correct sizing of the

safety measures is the sole responsibility of the electri-

cian connecting the heat pump.

OCHNSER provides no guarantee in cases of system

damage occurring due to incorrectly sized safety de-

vices!

Fig.16: Power supply to the heat pump

All three-phase drives (compressor,

pumps, fans) MUST be connected to a

CLOCKWISE field of rotation.

7.1 Cable cross sections

Position min. cross-

section

Connection cable 230V~:

(pumps, valve motors)

Connecting cables are always to

be sized according to on-site

conditions

1.5 mm².

Sensor cables:

(outside sensors, etc.) must al-

ways be run separately (min. 20

cm) from 230V/400V cables.

The maximum cable length must

not exceed 50 m.

1.0 mm².

Bus cables

(e.g. room remote control) bus

cables must always be laid as

sheathed cables. The sheathing is

to be earthed on one end -- > to

the heat pump on PE.

OCHSNER recommends the

following conventional cables:

Y(ST)Y) 2x2x0.8

0.8 mm².

Signal cables:

(5x 1.0mm², 2x 1.0mm²)

The signal cables between the

switching box Airstation and the

OTE control can be run according

to the hydraulic plan, without

sheathing.

1.0 mm².

Table 1: Wiring cross sections

Should the minimum clearances between

sensor wiring and 230V/400V (100mm)

not be able to be adhered to, sheathed

wiring is to be used.

This is to be especially considered for the outside

sensor wiring. OCHSNER accepts no warranty claims

for damage caused by insufficient protection against

electro-emission

7.2 Power supply wiring

The voltage supplies 400V~ and 230V~ are to be run

separately according to the circuit diagram. See also

Fig. 15

• 400V~ for the compressor

• 230V~ control voltage

• 400V~ DAE

• 400V~ optional for auxiliary heater for Le-

gionella treatment (outside unit).


The power supply 230V~ to the OTE control is on the

terminal strip X1 in the Airstation distribution box (L N

PE). This ensures that the OTE and the control in the

Airstation distribution box have the same phase and

neutral. This cable, as well as the signal cable between

OTE and the Airstation distribution box is already fitted

in the functional module and only has to be connected

to the Airstation distribution box with the flat connect-

ors (L, N) and to the earthing block (PE).

1 OTE 2 Airstation distribution box

Fig.17: OLWI distribution box

7.3 Switching off via tariff relay:

For switching by means of a tariff relay (sealed by the

Utility on site) the 3-phase power supply to the heat

pump is switched off. The heat pump signal contact

must be executed via the auxiliary contact on the tariff

relay

7.4 Utility control contact

In the case of tariff switching (interrupted power sup-

ply) the heat pump will be temporarily switched off by

the utility. For this, the control input Utility (PIN 21) is to

be connected to the control in the heat pump.

The appliance is delivered with PIN21 connected to

PIN 12 on the OTE. When using the Utility control

contact, this cable is disconnected from both PINs and

the Utility control contact connected to PIN 21.

7.5 Control wiring

Digital signals will be transmitted between the control

(OTE) and the Airstation A 5-pole control cable (W5 =

5x 1.0mm²) is used for this. This is already fitted in the

functional module and only has to be connected to the

Airstation distribution box.

1. Wire OTE Pin.11 --> DHC1 and DHC2

2. Wire OTE Pin.20 --> De-icing

3. Wire OTE Pin.4 --> RESET

4. Wire OTE Pin.24 --> HP-ON

5. Wire OTE Pin.19 --> working (Relay K1/A1)

7.6 eBus wiring

An eBus connection is required

between the OTE control and the auxiliary OTE mod-

ule or to the room remote controls and the room termi-

nal with Touch Display.

The communication between the eBus users is by

means of 4 x 1.0mm² wire.

For instance: EIB 4x0.8mm², whereby 2 wires can be

used together, thus providing a cross-section of >=

1.0mm². Ochsner recommends using sheathed wiring.

7.7 Sensor wiring

Do not place line voltage on the sensor

terminals! The control will otherwise be

destroyed.

The Type NTC5K temperature sensors of the OTE

control are supplied with 4.0m cables. Should this

4.0m not suffice, the cables can be extended to the

length required. Please use 2x 1.0mm² flexible cable.

When installing the sensor cable, ensure that the ca-

bles do not run parallel to alternate current >230VAC

cables.

Buffer sensors (TPO, TPM)

A minimum of 2 immersion sensors are to be installed

in the sleeves in the buffer tank. When selecting the

length of the immersion sleeves, take the thickness of

the insulation into consideration as well. 2 buffer sen-

sors are to be used:

Top buffer sensor (TPO)

Middle buffer sensor (TPM)

Fig.18: Heating buffer


Outside sensor TA

The outside sensor (TA) of the control is

to be mounted at ca. 2.5 m height on the outside wall

of the building (north-west side). It is to be ensured that

the outside sensor is not directly affected by sun's

radiation or by wind, as this will adversely affect the

control behaviour. Do not place the sensor in the direct

vicinity of the evaporator either. Possible danger of

adverse influence on the control.

Sensors TQE and TQA

The flow and return sensors for the heating system

(WNA) are to be installed close to the switching box

inside unit. Sensor length 1.5m

Mixer sensor TMK

If a mixing circuit is installed in addition to the direct

heating circuit, a mixing valve sensor must also be

installed. The mixing valve sensor is supplied as a

contact sensor with band clamp and conductive paste.

The mixing valve sensor is to be mounted directly after

the mixer pump. If multi-layer or plastic pipework is

being used, a suitable metal bridge must be provided.

Hot water sensor TB

The hot water sensor is packed in the heat pump on

delivery. The sensor should be placed in the bottom

third of the tank, maximum in the middle. Ochsner hot

water tanks are fitted with corresponding sleeves for

the installation.

The current electromagnetic compatibility guidelines

are to be adhered to during laying.

The sensors are to be checked after wiring up.

- plausible values

- correct position

- sensors mixed up?

7.8 Pumps, drives 230 VAC Pumps, (heating circuit pumps, hot water charge

pumps) as well as drives (mixing valves, etc.) are

connected directly to the control.

A test-run may only be undertaken on a fully-prepared

system that is ready for commissioning!

The hydraulics must be filled!

Danger of destroying the circulation pump!

A relay test can be carried out on the OTE control in

order to test the appropriate outputs (actuators).

The diverter modules from ESBE, which are delivered

by Ochsner, are not mixer motors, even when they

look similar.

7.9 Pumps, drives 400 VAC

3-phase pumps (heat source pump, charge pumps)

with higher ratings will not be directly connected to the

control. Power relays are provided in the distribution

box for this. See electrical circuit diagram Section 14.3

A separate circuit breaker is to be provided in the dis-

tribution box for the optional electrical auxiliary heater

in the hot water tank (Legionella protection). This func-

tion is optional and thus not in the heat pump's scope

of delivery.

A test-run may only be undertaken on a fully-prepared

system that is ready for commissioning!


8 Assembling the cladding

8.1 Sealing the appliance

Before you assemble the cladding, you must seal the

appliance by adhering tape in order to avoid conden-

sate in the appliance during all operational conditions.

The tape is in the cladding.

Fig.19: Seal the appliance inside (1)

► Tape over the hole in the bottom of the frame on the

left hand side with the fabric tape. The tape is in the

accessory "heat insulated air hose".


► Hang the foil with the pre-cut

holes on the hooks on the appliance.


► Remove the support layer of the tapes on the frame

8.4 Installing the air hoses

NOTE:

The ducting of the air inlet and air outlet to and from

the appliance takes place by means of air hoses.

These are highly flexible, heat insulated and are self-

extinguishing.

8.4.1 General

The air hose can be extended by twisting the spirals.

The overlap must be ca. 30 cm. The total hose length

must not exceed 8 m on the air inlet and air outlet

sides.

► Do not make more than four 90°- bends. The bend-

ing radius must be at least 600 mm, based on the

hose middle.

► Use a sharp knife to cut the hose. The wire spirals

can be cut with wire cutters.

► Fix the air hose at ca. 1 m intervals in order to pre-

vent the hose from sagging.

► Offer up the ends of the air hoses to the oval form of

the connecting sleeves of the cladding and the hose

connecting plates or wall conduits.

8.4.2 Installing the air hoses

►Fix the air hoses to the functional module by means

of the wing nuts provided.

► Mark up the fixing holes on the outside wall of the

building using the drill template provided.

► Use suitable wall plugs and screws to fix the air

hoses according to the wall structure.

8.4.3 Insulating the wall

Make sure that there are no thermal bridges between

the wall and the air connecting plates or wall conduits.

Thermal bridges can lead to condensation in the wall.

► If required, install a suitable heat insulation between

the wall and the air connecting plates or wall con-

duits.

► Observe the installation instructions for the wall

conduits.

9 Commissioning

Commissioning must be carried out by Ochsner Cus-

tomer Service or a service partner authorised by

Ochsner. The Ochsner commissioning guidelines must

be adhered to. Operating the system without a correct

commissioning will lead to a forfeiture of the guarantee

and warranty rights.

9.1 Required on-site personnel

Electrician, installer and future system supervisor

MUST be present for the system orientation during

commissioning.

INSTRUCTIONS for the system installer.

• The OCHSNER Customer Service engineer /

Customer Service partner will execute the user-

specific settings according to the specifications

in the system data sheet.

• Should the system installer not be present during

commissioning, or if there is no fully completed

system data sheet present, the system will be

commissioned using the control's factory settings.

• OCHSNER accepts no liability for possible mal-

functioning (heating curve too low, bivalent point

too high, etc.). Any claims resulting from this will

be invoiced to the system installer.

• In order to run the system economically,

it is absolutely necessary that the system be bal-

anced hydraulically and that the control settings

are coordinated to the system requirements.

• Other necessary work performed, such as bleed-

ing the system, electrical wiring, additional instruc-

tion etc., that do not fall within the realm of the

OCHSNER firm’s duties will be invoiced separate-

ly

9.2 Non-self-resetting safety thermostat

At outside temperatures below - 15 °C, the non-self-

resetting safety thermostat can trigger the electric

emergency/auxiliary heater. Check whether the safety

thermostat has been activated.

Reset the safety thermostat by pressing the reset

button.

1 safety thermostat reset button

2 electric emergency/auxiliary heater

Fig.25: Non-self-resetting safety thermostat

9.3 Appliance function

Electric emergency/auxiliary heater in the heat pump

flow:

• Mono-energetic operation

The electric emergency/auxiliary heater guaran-

tees the heating operation as well as higher water

temperatures if the outside temperature falls be-

low the bivalent point.

• Emergency operation

If the heat pump malfunctions, the heating will be

taken over by the electric emergency/auxiliary

heater.

• Heat-up program

(underfloor heating only)

For return temperatures <25 °C, the electric emergen-

cy/auxiliary heater must take over the drying out of the

flooring screed!

The drying out cannot be carried out using the heat

pump as the system temperatures are too low and,

during the de-icing cycle the frost protection cannot be

guaranteed.

At the end of the drying out program, the electric

emergency/auxiliary heater can be disconnected if it is

not needed for the normal appliance operation.

Please note that the emergency operation cannot be

activated during the drying out program.

Anti-legionella switching

The electric emergency/auxiliary heater will be auto-

matically switched on if the anti-legionella program is in

place. The water will be regularly heated to 60 °C as

protection against Legionella.


10 Operation

The heat pump operation takes place by means of the

basic operating panel. This is easily accessible in a

plastic housing mounted on the heat pump. The user

has 2 knobs and a lit display at his disposal

(Fig. 26).

Fig. 26 : Basic control panel

The heat pump has no

separate main switch. In emergency the

system MUST be switched off by means

of the specified circuit breakers.

The circuit breakers MUST be so reachable as to en-

sure a switching off at any time.

Further notes on the control operation can be found

in the current OTE Operating Instructions,

which are supplied with every heat pump.

10.1 Safety functions

Following safety features are implemented from both

Hard- and Software:

- Electronic control and safety devices for the

compressor

- High pressure pressostat

- Start delay to avoid

compressor chopping.

- Frost protection function

- Start-up- and run-down times of the fans

10.2 Running costs

During the first heating season, higher running costs

can generally be expected, depending on the residual

moisture in the building - up to 50%.

10.2.1 Flow temperatures

In order to achieve an optimum heat pump operation,

the lowest possible heating system flow temperatures

(and hot water temperatures) are to be aimed at. The

max. system temperature for heat pumps of the

OLW Series is to be limited to 60°C.

NOTE:

An increase of the room temperature by 1°C means a

5-7% increase in energy consumption.

10.2.2 Ventilation

Intermittent intensive ventilation according to own

requirements should be carried out, especially during

the heating period. Intermittent intensive ventilation is

much more energy-efficient

and thus more economical.

Continuous ventilation should be avoided on principle.


11 Maintenance

11.1 Service work

Accessibility of the heat pump and ancillary appli-

ances is to be ensured for service work at all

times!

The heat pump operates essentially maintenance-free.

It must, however, be ensured that:

- the evaporator is free from leaves and twigs

or any other foreign bodies,

- the condensation can drain off,

- the heating circuit contains enough water

NOTE:

In order to prevent additional costs, it is recommended

to have the heat pump serviced at least once per year.

Furthermore,

legal regulations require that heating appliances be

checked and serviced regularly by the user.

OCHSNER can, if desired, offer a service contract in

order to carry out any necessary leakage tests and

checking of safety equipment of

the heat pump.

If required, please contact our customer service de-

partment.which will test the functionability, efficiency

and safety functions of the machine as well as check-

ing the control and regulation equipment. Your ad-

vantages of servicing: Correctly carried out servicing

not only saves energy, it also protects the environ-

ment. Furthermore, the correct care of the heating

system is a necessary prerequisite in order to safe-

guard the operational life of the heat pump for many

years. This gives the system user increased protection

against malfunctioning and ensures guarantee claims.

A

service contract provides continuity. In order to ensure

that

the monitoring and care of the heat pump is carried out

at regular intervals,

it is recommended to conclude a service contract. A

fully filled out protocol documents the working results

and the machine's condition.

The water pressure in the heating system is to be

monitored by the system operator and adjusted if the

the pressure is too high or too low.

The flow rates in the heating system are to be moni-

tored with the flow meters specified by OCHSNER.

Furthermore, the specified system service intervals as

well as the system checks must be adhered to.

If, during larger reconstruction work or after burst pip-

ing the majority of the water in the heating system has

to be drained off and refilled, this must be carried out in

the presence of the OCHSNER works customer ser-

vice / OCHSNER authorised partner (see Logbook)

If exceptional refilling work is to be carried out (e.g.

reconstruction work or after burst piping), a current

water test report is to be made and, if necessary, using

this report, additives must be used when refilling the

heating system.

Note

On request, OCHSNER can offer a maintenance con-

tract. If required, please contact our customer service

department.

11.2 Cleaning


Service work, for instance checking the electrical safe-

ty, must only be carried out by a specialist electrician.

► Protect the appliance from dust and dirt during the

construction phase.

► A moist cloth is sufficient to care for the plastic

and metal parts. Do not use scouring or dissolving

cleaning agents.

► Check the condensate drain function once per

month (visual control). Check whether water has

accumulated under or alongside the appliance. Ob-

serve the Section "Troubleshooting".

We recommend an annual inspection (determination of

current condition) and, if required, servicing (estab-

lishment of correct condition) by a specialist installer or

the OCHSNER Customer Service.

11.3 Customer Service

12 Decommissioning and disposal

12.1 Disposal of transport packaging

The heat pump's transport packaging consists of recy-

clable raw materials. Packaging should thus be sorted

and recycled. The disposal of the transport packaging

is undertaken by the specialist company that installed

the equipment.

12.2 Decommissioning

All live connections are to be discon-

nected from the power supply by a

specialist before decommissioning.

Appliances which contain refrigerant may only be de-

commissioned by an authorised specialist firm (cool-

ing/air-conditioning/heating). The refrigerant resp.

brine fluid is to be evacuated/removed correctly by the

specialist firm and and recycled rsp. disposed of.

Incorrect disposal of the refrigerant can

lead to considerable environmental

damage!

12.3 Disposal of the appliance

The disposal of the decommissioned heat

pump should be carried out according to

regional environmental regulations and

standards at regional waste collection

points.

The heat pump may not be disposed

of in household

waste!

17 Warranty

The OCHSNER Company's general terms of delivery

apply. Retrievable at www.ochsner.at

- The design and sizing of the system must be

carried out in accordance with the OCHSNER

guidelines and standards applicable at the respec-

tive time.

- The heat pump is sized and tested exclusively

for operation in public utility electricity supply

networks. Any claims for possible malfunctions or com-

ponent damage arising from operation in a

excluded from the warranty.

- Warranty period: For supplied appliances, we

accept a warranty for a period of 2 years from

commissioning, however, not more than 27

months from delivery

. Recourse claims pursuant to section 933 b

ABGB (Austrian Civil Code) are excluded. Place

of performance for all warranty claims and claims

for damages is the Company's registered place of

business.

- Commissioning: The heat pump must be com-

missioned by the OCHSNER customer service or

by an authorised Ochsner service partner. Com-

missioning of the heat pump by the Supplier does

not lead to any transfer of liability for potential de-

fects in the system. If commissioning is carried out

under reservation or by persons who have not

been authorised accordingly in writing, any war-

ranty claims shall cease to apply.

Warranty conditions (excerpt from the Stand-

ard Terms and Conditions of Supply)

- The Customer shall be obligated to make notifica-

tion in writing of any defects immediately, howev-

er, at the most within 3 days from delivery, and

prior to any work on, or processing of, the goods,

including an exact description of the defects, as

otherwise any warranty claims and/or claims for

damages and/or claims for avoidance on account

of an error shall be excluded; however, such de-

fects shall not give the Customer the right to with-

hold the invoice sums or parts thereof. In the

event of visible transport damage, the Customer

shall be obligated to inspect the goods prior to tak-

ing over the transport goods, and to report any

immediately visible transport damage.

- For defects which were unable to be found during

the incoming inspection, the warranty period shall

be two years from delivery, and shall neither be

extended nor suspended by improvement at-

tempts; it shall also apply to partial deliveries.

Such defects must be notified in writing within 3

days from their detection, as otherwise any war-

ranty claims and/or claims for damages and/or

claims for avoidance on account of an error shall

be excluded;

- Deviations of the ordered products from the deliv-

ered products, such as incorrect dimensions or

wrong product ("aliud delivery") must be notified

within 3 days from delivery, and prior to any for-

warding and/or work on, or processing of, the

goods Otherwise, the object shall be deemed to

have been approved and can no longer be taken

back or exchanged by us.

- Our consultancy services, whether verbal or in

writing, are non-binding and will not release our

Customers from the obligation of themselves ex-

amining the contractual product with regard to its

suitability for the intended purpose. For subse-

quent deliveries, we do not accept any warranty

with regard to the exact identity with the initial de-

livery. The commissioning of the Ochsner ma-

chines must always be carried out by Ochsner or

by a service partner authorised in writing by

Ochsner. Commissioning itself is limited to the

components supplied by Ochsner, but does not

include the entire heating system or system com-

ponents which were not delivered by Ochsner.

The assumption of liability after commissioning for

the entire heating system or for third-party system

components is excluded.

- The technical requirements for the design and

installation of the system of the products supplied

by us as set out in manuals, installation instruc-

tions or similar documents only contain standard

minimum requirements, without claiming to be ex-

haustive. The customer is obliged to adhere to the

current state-of-the-art technology as well as the

OCHSNER guidelines, otherwise all warranty

claims and any guarantees will be invalid. In par-

ticular, we shall not assume any warranty or liabil-

ity for the calculations made by the Customer with

regard to the efficiency of the contractual object

provided by us or with regard to the suitability of

the contractual object provided by us for the appli-

cation purposes intended by the Customer, except

if this has been agreed separately and in writing.

- Warranty for parts subject to wear and tear, as

well as operating materials such as filters, filter

cartridges, anodes as well as electrical compo-

nents, circulating pumps, E-rod heaters, fittings

and plate heat exchangers (for instance due to

chalking, corrosion, dry-running, unsuitable water

quality) is excluded. In case of doubt, proof of

compliance with the water qualities in accordance

with VDI 2035 must be provided by the Customer.

The corrosion protection anode is to be proved to

have been serviced.

http://www.ochsner.at/


We furthermore would like to point out that rust

film may occur on all parts which are exposed to

the atmosphere.

- The Customer shall always be obligated to prove

that the contractual object was defective at the

time it was handed over; the legal presumption in

section 924 of the ABGB is expressly excluded.

- With regard to the contractual objects supplied by

us, we only warrant that they have the characteris-

tics which are usually assumed by the relevant

trade circles to exist in such objects. Any charac-

teristics going beyond this, including in particular

those included in public statements - such as ad-

vertising and in the information enclosed with the

contractual objects - shall only be covered by our

warranty if we have warranted such characteris-

tics in writing in the context of the placement of

the order.

- Notwithstanding any other provisions in these

Standard Terms and Conditions of Sale and De-

livery, warranty shall expire

i) if the Customer, either himself or through third

parties, carries out modifications or rectifications

of the contractual object

ii) if parts are used which are not original accesso-

ries.

iii) if the contractual goods are used in an unusual

manner,

iv) if the installation and operating instructions are

not complied with,

v) if the system data sheet is not filled in,

vi) if the system is commissioned by persons other

than the Ochsner customer service or a service

partner who has been authorised in writing,

vii) if supplementary installations are defective,

such as inadequate flow rates or system bridges,

lack of flow rate monitors, lack of E-rods for heat

source air, external control, interference with the

control, soiling during construction phase, insuffi-

cient water quality, lack of hydraulic separation,

non-specified valves.

viii) if dimensioning is incorrect or if the heat

source system is installed incorrectly,

ix) if evaporators are not connected in accordance

with the installation and connection guidelines.

- We shall only assume warranty for the functioning

of our products, but not for their outer appearance.

Any warranty obligation shall always relate to the

defective appliance components, but shall not in-

clude the working time required to eliminate the

defect, nor the travel costs.

- We shall not assume any warranty for operating

costs and noise emission at the installation site,

as these depend on the configuration of the sys-

tem, the building, the weather, the user behaviour

and the control settings.

- It shall be at our choice whether we fulfil the war-

ranty claims by exchanging or rectifying the prod-

ucts, by reducing the price or by rescinding the

contract.

- Our liability for any damage incurred by our Cus-

tomers within the course of the handling of the

transaction shall be limited as a maximum of the

value of the order which gave rise to the damage,

and shall always only apply in the event of our

own gross negligence or of gross negligence

on the part of our vicarious agents, with the ex-

ception of damage to persons, for which we shall

also be liable in the event of slight negligence. Re-

imbursement for consequential damage, pure as-

set damages, loss of profit and damages from

third party claims is excluded.

- The Customer must comply strictly with the in-

structions included in operating instructions, man-

uals and other product information documents, in

order to prevent potential damage. The Customer

is expressly warned against any application going

beyond the defined areas of application.


18 ANNEX

18.1 Setting the flow rate

The nominal flow rate (see 18.2) is to be ensured in all types of operation /hot water charging, heating, cooling via a

separate buffer tank etc.). The flow rates are measured by the installed flow meter and displayed on the OTE control.

The flow rate is adjusted by means of the adjustment screw on the circulation pump supplied. For a hydraulic regulation

corresponding to the standards, especially by combined heating rsp. heating/cooling operation with hot water heating,

appropriate pipe-run regulating valves are to be fitted and the system calibrated as required.

Fig.31: Setting the flow rate of the EC pump

Procedure

1) Switch on the buffer charge pump (heat generator pump) via the relay test.

Fig.32: Switch on heat generator pump

2) The measured flow rate is displayed, this must correspond to the nominal flow.

Fig.33: Reading flow rate

Setting ∆p-c

Set the flow rate by

turning the red adjustment screw.
