2.1.2 CONTROL AND FUNCTIONS ○ Sherpa can be activated for:
• heating, • cooling, • domestic water production only, • cooling or heating with domestic water.
○ The control can manage one climate curve for heating and another for cooling to vary the water tem-perature of the system in relation to the outdoor weather conditions, adapting the amount of heat to the heating requirements of the building in order to save energy.
○ There is a daily timer with night-time mode that permits up to 20% energy savings.
○ Sherpa offers two methods for the highly flexible management of Domestic Hot Water: • water probe on board the machine;• water probe in the boiler.
○ The probe in the DHW tank also allows Sherpa to manage anti-legionella cycles; when there is an electrical heater element in the DHW tank, the anti-legionella cycle runs without interrupting the heating or cooling cycle of the air-conditioning system.
○ The set-points available are:• two set-points for cooling;• two set-points for heating that can be activated at the button on the Eco control panel or via remote
contacts;• a set-point for defining the temperature of the domestic water.
○ The units have a supporting two-stage heater element: • 1.5kW + 1.5kW on SMALL internal units,• 3 kW + 3 kW on LARGE units. These can be enabled to integrate power for heating, the production of domestic water, and the anti-legionella cycles. Once enabled, the heater elements start automatically the moment the low outdoor air temperature does not allow the heat pump to meet the heating load or when the exter-nal unit malfunctions (back-up function). It is possible to enable just one or both the stages of the electrical heater element according to needs or the electrical power available. This function requires installation of the outdoor air temperature probe kit (optional).
○ The following functions can be remote controlled with free contacts:• switching on/off;• heating/cooling mode;• activation of the second set-point (Eco mode);• activation of night-time mode;• activation of heating of domestic water storage;• enabling/disabling of air conditioning (only production of DHW). The unit may also be connected to a chrono-thermostat or to the chiller/boiler contacts of the elec-tronic controls of the fan coils Bi2 and Bi2+.
○ Sherpa can activate an auxiliary external heat source (e.g. heater) to substitute the heat pump unit, in relation to the outdoor air temperature. This function requires installation of the outdoor air tempera-ture probe kit (optional).
○ The following accessories are available:• Code B0622 - 3-way valve kit for domestic hot water;• Code B0623 - Outdoor air probe kit;• Code B0624 - DHW boiler sensor kit;• Code B0665 - Heating cable kit.

2.1.7 USEFUL HEADS OF THE SYSTEM The water circulation pump permits the following two types of control:
○ with constant pressure differential. ○ with variable pressure differential.
The pump with permanent magnet wet rotor has an electronic control module with integrated frequency converter. There is a control knob on the module.
SETTINGS USING THE CONTROL KNOB
2
Mode A: Variable differential pressure (Δp-v). The differential-pressure set-point is increased linearly over the permitted volume flow range between ½
H and H (Δp-v graph). The differential pressure generated by the pump is adjusted to the corresponding differential-pressure
set-point.This control mode is especially useful in heating systems with fan coils and radiators, since the flow noise at the thermostatic valves is reduced.
2
Mode B: Constant differential pressure (Δp-c). The differential pressure set-point H is constantly maintained, within the permitted
delivery range, at the programmed set-point up to the maximum characteristic curve (Δp-c graph). This regulation method is recommended for floor mounted heating systems or older heating systems with large pipelines, but also for all other applications that do not have variable characteristic curves, such as for example DHW boiler pumps.

CHydraulic connection - head Fig. 3
If greater heads are required due to high pressure losses in the system, an inertial vessel or a hydraulic separator and an external idle pump must be added. The system must have a minimum water content required(Tab. 52 and Tab. 53) to ensure good system operation. If it is insufficient, add a storage vessel in order to reach the required content.The water distribution pipes must be suitably insulated with expanded polyethylene or similar materials. The on/off valves, bends and unions must also be suitably insulated. To prevent air locks inside the cir-cuit, insert automatic or manual breather devices at all the points (high pipes, traps etc.) where air may accumulate.

2.1.9.4 POSITIONING OF THE EXTERNAL UNITS
Install the external unit (Fig. 10) on a solid base that is able to support its weight; if installed incompletely or onto an inappropriate base, the unit could cause damage to persons or property, if it should detach from the base.
It is very important that the installation place be chosen with extreme care in order to ensure adequate protection of the device against impact or possible consequential damage. Choose a place that is ade-quately ventilated and in which the outdoor temperature in summer does not exceed 46°C.
Leave sufficient free space around the appliance in order to avoid recirculation and to facilitate maintenance. Prepare a layer of gravel underneath the appliance for drainage of the defrost water.
Leave space underneath the unit to prevent the defrost water from freezing. In normal situations, ensure the base is at least 5 cm off the ground; for use in regions with very cold winters, ensure a space of at least 15 cm on both sides of the unit. When installed in a location with high snow fall, mount the support of the appliance at a height that is above the maximum level of snow.Install the unit so that wind is not blowing across it.
Also prepare: ○ anti-vibration dampers; ○ compliant power supply near the external unit.

Positioning of the external units Fig. 10
The external unit is supplied with a mesh for covering the heat exchange battery; this is envisaged for installations accessible to the public. Fitting the mesh may cause, in the event of high humidity at low temperature (fog) or snow, a build-up of ice on the battery with reduced system performance.

and maintenance manual supplied with each unit and accessory. This technical booklet provides general information on installation, dimensional drawings and wiring diagrams.
The installation must be carried out by the dealer or by other qualified personnel; if the installation is not carried out correctly, there may be a risk of water leakage, electric shock or fire.
During assembly and any maintenance operation, observe the precautions in the installation, use and maintenance manuals and on the labels inside the appliances, and take any precautions dictated by common sense and set down by the safety rules at the place of installation.
Always wear protective gloves and goggles when performing maintenance on the parts of the appliances
containing refrigerant. Air-water heat pumps MUST NEVER be installed in rooms where there is inflam-mable gas, explosive gas, a high level of humidity (laundry rooms, greenhouses etc.), or in rooms where there are other machines generating a lot of heat.
It is recommended to use only the components designed specially for the installation provided; the use of different components could cause the leakage of water, electric shock or fire.
Once the installation has been completed, check that there is no leakage of refrigerant (the liquid can produce toxic gas when exposed to flames).
When installing or relocating the system, make sure that there is no substance in the refrigerant circuit other than the refrigerant specified in the technical data (see para. 2.1.4) as the presence of air or other foreign substances in the refrigerant circuit can cause an abnormal increase in pressure or breakage of the system, resulting in damage to property or physical injury.

2.2 SHERPA AQUADUE - MULTI-PURPOSE SPLIT TECHNOLOGY TECHNICAL BOOKLET
2.2.1 FUNDAMENTAL CHARACTERISTICS ○ Reversible air-water heat pump split system. ○ System with two modules: external unit and internal hydronic module. ○ Supplies technical water for DHW boiler at a temperature of up to 75°C. ○ Availability of DHW at all times: guaranteed by the system with dual refrigerant circuit. ○ Two-stage electrical heater elements as standard: activation of one or two elements to support the
heat pump with simple configuration of the electronic control. Each stage is activated according to the need for heating power in real time, in order to optimise power consumption.
○ A water-water heat pump unit integrated in the internal unit provides hot water at high temperature regardless of outdoor weather conditions for the production of DHW.
○ Anti-legionella cycles can be avoided with use of the high temperature water-to-water heat pump (up to 75°C).
○ Configurable climate curves with the outdoor air temperature probe: two curves available, one for cooling and one for heating.
○ Weekly, DHW, holiday and daily timer with night-time mode. ○ Configurable set-points: two set-points for cooling and three set-points for heating (one of which for
DHW) which can also be selected via remote contact. ○ Refrigerants: R410A* for the reversible circuit for air-conditioning and DHW; R134a** for the high
temperature circuit for the production of DHW at high temperature.

○ A large colour LCD touch screen facilitates installation, use and maintenance of the appliance with the following: • synoptic window;• graph of the temperature readings of the probes;• diagnostics with the INPUT/OUTPUT states of the control board and alarm log. The control can manage one climate curve for heating and another for cooling to vary the water tem-perature of the system in relation to the outdoor weather conditions.
○ The control can manage one climate curve for heating and another for cooling to vary the water tem-perature of the system in relation to the outdoor weather conditions, adapting the amount of heat to the heating requirements of the building in order to save energy.
○ There is a weekly timer with a max of 8 daily time bands for the modes:• cooling/heating;• ECO function;• night-time function. There is a specific timer for the production of DHW. It is possible to set up to 3 "holiday" periods during which the system is deactivated with the frost protection and pumps anti-locking function active.
○ Sherpa Aquadue permits highly flexible management of the production of Domestic Hot Water with an outdoor boiler in two modes:• with diversion of the flow of hot water from the heating circuit to the DHW circuit up to a maximum
temperature of 60°C with the system running at full capacity;• using the water-water heat pump integrated in the internal unit up to a maximum temperature of
75°C.
○ Sherpa Aquadue is able to manage anti-legionella cycles without interrupting the heating or cooling cycle of the air conditioning system, producing hot water at high temperature using the integrated heat pump circuit.
○ The following are available for both cooling and heating mode:• a "comfort" set-point;• an ECO set-point. The set-points can be selected with the ECO command on the control panel or by closing an appro-priate input on the electronic board (remote contact).
○ The DHW production function can be activated by the temperature sensor in the storage tank or by closing an appropriate input on the electronic board (remote contact).
○ There is a specific set point for the DHW production function, and it is possible to change the main operating parameters of the same function for optimal operation in the various situations of installa-tion.
○ The internal units have a supporting two-stage heater element. These elements, if enabled, can be activated to supplement the power of the system in heating mode or for the production of DHW when low outdoor air temperature does not allow the heat pump to meet the heating load or when the external unit malfunctions (back-up function). It is possible to enable just one or both the stages of the electrical heater element according to needs or on the basis of the electrical power available.

The supporting electrical heater elements can be enabled during the functions of heating or production of domestic hot water even outside the operating range of the heat pump.
If the unit is installed in a particularly windy area, wind barriers must be put in place to avoid malfunc-tioning of the unit.

2.2.7 USEFUL HEADS OF THE SYSTEM Sherpa Aquadue is equipped with two high efficiency circulation pumps.
The technical water circulation pump permits the following two types of control: ○ With constant pressure differential (mode A). ○ With variable pressure differential (mode B).
The technical water circulation pump of the DHW circuit permits the following two types of control: ○ With constant pressure differential (mode A). ○ Three constant speeds (mode C).
IT is equipped with two high efficiency circulation pumps: the pumps with permanent magnet wet rotor have an electronic control module with integrated frequency converter. There is a control knob on the module.
An LED on the DHW pump indicates the operating status of the pump.All the functions can be set, activated and deactivated at the control knob.
SETTINGS USING THE CONTROL KNOB
2
Mode A: Variable pressure difference (Δp-v) (available for the pump of the air-conditioning circuit and the DHW pump).
The differential-pressure set-point is increased linearly over the permitted volume flow range between ½ H and H (Δp-v graph).
The differential pressure generated by the pump is adjusted to the corresponding differential-pressure set-point.This control mode is especially useful in heating systems with fan coils and radiators, since the flow noise at the thermostatic valves is reduced.
2
Mode B: Constant pressure difference (Δp-c) (available for the pump of the air-conditioning circuit). The differential pressure set-point H is constantly maintained, within the permitted delivery range, at the
programmed set-point up to the maximum characteristic curve (Δp-c graph). This regulation method is recommended for floor mounted heating systems or older heating systems with large pipelines, but also for all other applications that do not have variable characteristic curves, such as for example DHW boiler pumps.
Mode C: Constant speed I, II and III (available for DHW pump). The circulation pump works like a conventional three-speed pump but uses less energy.

Hydraulic connection - head Fig. 23
If greater heads are required due to high pressure losses in the system, an inertial vessel or a hydraulic sep-arator and an external idle pump must be added. The system must have a minimum water content required to ensure good system operation. If it is insufficient, add a storage vessel in order to reach the required content. The water distribution pipes must be suitably insulated with expanded polyethylene or similar materials. The on/off valves, bends and unions must also be suitably insulated. To prevent air locks inside the cir-cuit, insert automatic or manual breather devices at all the points (high pipes, traps etc.) where air may accumulate.

2.2.9.4 POSITIONING OF THE EXTERNAL UNITS
Install the external unit (Fig. 30) on a solid base that is able to support its weight; if installed incompletely or onto an inappropriate base, the unit could cause damage to persons or property, if it should detach from the base.
It is very important that the installation place be chosen with extreme care in order to ensure adequate pro-tection of the device against impact or possible consequential damage. Choose a place that is adequately ventilated and in which the outdoor temperature in summer does not exceed 46°C.
Leave sufficient free space around the appliance in order to avoid recirculation and to facilitate mainte-nance.
Prepare a layer of gravel underneath the appliance for drainage of the defrost water.Leave space underneath the unit to prevent the defrost water from freezing. In normal situations, ensure the base is at least 5 cm off the ground; for use in regions with very cold winters, ensure a space of at least 15 cm on both sides of the unit. When installed in a location with high snow fall, mount the support of the appliance at a height that is above the maximum level of snow.Install the unit so that wind is not blowing across it.
Also prepare: ○ anti-vibration dampers; ○ compliant power supply near the external unit.

Positioning of the external units Fig. 30
The external unit is supplied with a mesh for covering the heat exchange battery; this is envisaged for installations accessible to the public. Fitting the mesh may cause, in the event of high humidity at low temperature (fog) or snow, a build-up of ice on the battery with reduced system performance.

SHERPA AQUADUE TECHNICAL BOOKLETHEAT PUMPS
2.2.10 INSTALLATION To ensure successful installation and optimal performance, follow the instructions in the installation, use
and maintenance manual supplied with each unit and accessory. This technical booklet provides general information on installation, dimensional drawings and wiring diagrams.
The installation must be carried out by the dealer or by other qualified personnel; if the installation is not carried out correctly, there may be a risk of water leakage, electric shock or fire.
During assembly and any maintenance operation, observe the precautions in the installation, use and maintenance manuals and on the labels inside the appliances, and take any precautions dictated by common sense and set down by the safety rules at the place of installation.
Always wear protective gloves and goggles when performing maintenance on the parts of the appliances
containing refrigerant. Air-water heat pumps MUST NEVER be installed in rooms where there is inflam-mable gas, explosive gas, a high level of humidity (laundry rooms, greenhouses etc.), or in rooms where there are other machines generating a lot of heat.
It is recommended to use only the components designed specially for the installation provided; the use of different components could cause the leakage of water, electric shock or fire.
Once the installation has been completed, check that there is no leakage of refrigerant (the liquid can produce toxic gas when exposed to flames).
When installing or relocating the system, make sure that there is no substance in the refrigerant circuit other than the refrigerant specified in the technical data (see para. 2.2.4) as the presence of air or other foreign substances in the refrigerant circuit can cause an abnormal increase in pressure or breakage of the system, resulting in damage to property or physical injury.

2.3 SHERPA AQUADUE TOWER - MULTI-PURPOSE SPLIT TECHNOLOGY TECHNICAL BOOKLET
2.3.1 FUNDAMENTAL CHARACTERISTICS
○ Reversible air-water heat pump split system. ○ System with two modules: external unit and internal hydronic module. ○ Supplies technical water for DHW boiler at a temperature of up to 75°C in the integrated boiler. ○ Production of technical water for mixed boiler at 40°C up to 3-6 days.* ○ Availability of DHW at all times: guaranteed by the redundancy of the system with dual refrigerant circuit. ○ Two-stage electrical heater elements as standard: activation of one or two elements to support the heat
pump with simple configuration of the electronic control. Each stage is activated according to the need for heating power in real time, in order to optimise power consumption.
○ A water-water heat pump unit integrated in the internal unit provides hot water at high temperature re-gardless of outdoor weather conditions for the production of DHW.
○ Anti-legionella cycles can be avoided with use of the high temperature water-to-water heat pump (up to 75°C).
○ Climate curves with the outdoor air temperature probe: two curves available, one for cooling and one for heating. The climate curves make it possible to vary the water temperature of the system in relation to the outdoor weather conditions, adapting the heating requirements of the building in order to save energy.
○ Weekly, DHW, holiday and daily timer with night-time mode. ○ Configurable set-points: two set-points for cooling and three set-points for heating (one of which for
DHW) which can also be selected via remote contact. ○ Refrigerants: R410A** for the reversible circuit for air-conditioning and R134a*** for the high tempera-
ture circuit for the production of DHW. ○ Integrated high efficiency 150 l boiler.
* Qref 2.1 kWh/day for 150 l tank according to standard EN16147, 2005. ** Equipment not hermetically sealed containing fluorinated gases with an equivalent GWP of 2088. *** Equipment not hermetically sealed containing fluorinated gases with an equivalent GWP of 1430.

SHERPA AQUADUE TOWER TECHNICAL BOOKLETHEAT PUMPS
2.3.2 CONTROL AND FUNCTIONS ○ Sherpa Aquadue Tower can be activated for:
• heating;• cooling;• domestic water production only;• cooling or heating and the simultaneous production of domestic water at a temperature of up to
75°C.
○ A large colour LCD touch screen facilitates installation, use and maintenance of the appliance with the following: • synoptic window;• graph of the temperature readings of the probes;• diagnostics with the INPUT/OUTPUT states of the control board and alarm log. The control can manage one climate curve for heating and another for cooling to vary the water tem-perature of the system in relation to the outdoor weather conditions.
○ The control can manage one climate curve for heating and another for cooling to vary the water tem-perature of the system in relation to the outdoor weather conditions, adapting the amount of heat to the heating requirements of the building in order to save energy.
○ There is a weekly timer with a max of 8 daily time bands for the modes:• cooling/heating;• ECO function;• night-time function. There is a specific timer for the production of DHW. It is possible to set up to 3 "holiday" periods during which the system is deactivated with the frost protection and pumps anti-locking function active.
○ Sherpa Aquadue Tower permits highly flexible management of the production of Domestic Hot Water with an outdoor boiler in two modes:• with diversion of the flow of hot water from the heating circuit to the DHW circuit up to a maximum
temperature of 60°C with the system running at full capacity;• using the water-water heat pump integrated in the internal unit up to a maximum temperature of
75°C.
○ Sherpa Aquadue Tower is able to manage anti-legionella cycles without interrupting the heating or cool-ing cycle of the air conditioning system, producing hot water at high temperature using the integrated heat pump circuit.
○ The following are available for both cooling and heating mode:• a "comfort" set-point;• an ECO set-point. The set-points can be selected with the ECO command on the control panel or by closing an appro-priate input on the electronic board (remote contact).
○ The DHW production function can be activated by the temperature sensor in the storage tank or by closing an appropriate input on the electronic board (remote contact).
○ There is a specific set point for the DHW production function, and it is possible to change the main op-erating parameters of the same function for optimal operation in the various situations of installation.
○ The internal units have a supporting two-stage heater element. These elements, if enabled, can be activated to supplement the power of the system in heating mode or for the production of DHW when low outdoor air temperature does not allow the heat pump to meet the heating load or when the external unit malfunctions (back-up function). It is possible to enable just one or both the stages of the electrical heater element according to needs or on the basis of the electrical power available.

2.3.7 USEFUL HEADS OF THE SYSTEM Sherpa Aquadue Tower is equipped with two high efficiency circulation pumps.
The technical water circulation pump permits the following two types of control: ○ With constant pressure differential (mode A). ○ With variable pressure differential (mode B).
The technical water circulation pump of the DHW circuit permits two types of control: ○ With constant pressure differential (mode A). ○ Three constant speeds (mode C)
IT is equipped with two high efficiency circulation pumps: the pumps with permanent magnet wet rotor have an electronic control module with integrated frequency converter. There is a control knob on the module.
An LED on the DHW pump indicates the operating status of the pump. All the functions can be set, activated and deactivated at the control knob.
SETTINGS USING THE CONTROL KNOB
2
Mode A: Variable pressure difference (Δp-v) (available for the pump of the air-conditioning circuit and the DHW pump).
The differential-pressure set-point is increased linearly over the permitted volume flow range between ½ H and H (Δp-v graph).
The differential pressure generated by the pump is adjusted to the corresponding differential-pressure set-point.This control mode is especially useful in heating systems with fan coils and radiators, since the flow noise at the thermostatic valves is reduced.
2
Mode B: Constant pressure difference (Δp-c) (available for the pump of the air-conditioning circuit). The differential pressure set-point H is constantly maintained, within the permitted delivery range, at the
programmed set-point up to the maximum characteristic curve (Δp-c graph). This regulation method is recommended for floor mounted heating systems or older heating systems with large pipelines, but also for all other applications that do not have variable characteristic curves, such as for example DHW boiler pumps.
Mode C: Constant speed I, II and III (available for DHW pump). The circulation pump works like a conventional three-speed pump but uses less energy.

Hydraulic connection - head Fig. 42
If greater heads are required due to high pressure losses in the system, an inertial vessel or a hydraulic separator and an external idle pump must be added. The system must have a minimum water content required to ensure good system operation. If it is insufficient, add a storage vessel in order to reach the required content.The water distribution pipes must be suitably insulated with expanded polyethylene or similar materials. The on/off valves, bends and unions must also be suitably insulated. To prevent air locks inside the circuit, insert automatic or manual breather devices at all the points (high pipes, traps etc.) where air may accumulate.

2.3.9.4 POSITIONING OF THE EXTERNAL UNITS
Install the external unit (Fig. 50) on a solid base that is able to support its weight; if installed incompletely or onto an inappropriate base, the unit could cause damage to persons or property, if it should detach from the base.
It is very important that the installation place be chosen with extreme care in order to ensure adequate protection of the device against impact or possible consequential damage. Choose a place that is ade-quately ventilated and in which the outdoor temperature in summer does not exceed 46°C.
Leave sufficient free space around the appliance in order to avoid recirculation and to facilitate mainte-nance.
Prepare a layer of gravel underneath the appliance for drainage of the defrost water.Leave space underneath the unit to prevent the defrost water from freezing. In normal situations, ensure the base is at least 5 cm off the ground; for use in regions with very cold winters, ensure a space of at least 15 cm on both sides of the unit. When installed in a location with high snow fall, mount the support of the appliance at a height that is above the maximum level of snow.Install the unit so that wind is not blowing across it.
Also prepare: ○ anti-vibration dampers; ○ compliant power supply near the external unit.

Positioning of the external units Fig. 50
The external unit is supplied with a mesh for covering the heat exchange battery; this is envisaged for installations accessible to the public. Fitting the mesh may cause, in the event of high humidity at low temperature (fog) or snow, a build-up of ice on the battery with reduced system performance.

2.3.10 INSTALLATION To ensure successful installation and optimal performance, follow the instructions in the installation, use
and maintenance manual supplied with each unit and accessory. This technical booklet provides general information on installation, dimensional drawings and wiring diagrams.
The installation must be carried out by the dealer or by other qualified personnel; if the installation is not carried out correctly, there may be a risk of water leakage, electric shock or fire.
During assembly and any maintenance operation, observe the precautions in the installation, use and maintenance manuals and on the labels inside the appliances, and take any precautions dictated by common sense and set down by the safety rules at the place of installation.
Always wear protective gloves and goggles when performing maintenance on the parts of the appliances
containing refrigerant. Air-water heat pumps MUST NEVER be installed in rooms where there is inflam-mable gas, explosive gas, a high level of humidity (laundry rooms, greenhouses etc.), or in rooms where there are other machines generating a lot of heat.
It is recommended to use only the components designed specially for the installation provided; the use of different components could cause the leakage of water, electric shock or fire.
Once the installation has been completed, check that there is no leakage of refrigerant (the liquid can produce toxic gas when exposed to flames).
When installing or relocating the system, make sure that there is no substance in the refrigerant circuit other than the refrigerant specified in the technical data (see para. 2.3.4) as the presence of air or other foreign substances in the refrigerant circuit can cause an abnormal increase in pressure or breakage of the system, resulting in damage to property or physical injury.

2.4.2 CONTROL AND FUNCTIONS ○ Sherpa Monobloc comes as standard with a wired remote control with large LCD panel that displays
graphical symbols, the settings and temperature values.
○ The control can be used to run Sherpa Monobloc for:• heating, • cooling, • domestic water production.
○ The control has twelve climate curves for heating mode and two for cooling mode. The climate curve makes it possible to vary the water temperature of the system in relation to the outdoor weather con-ditions, adapting the amount of heat to the heating requirements of the building and permitting up to 20% energy savings. It is also possible to create customised climate curves.
○ There are three programming modes that can be selected at the "Touch 'N' Go" buttons under the control LCD panel:• indoor,• outdoor,• night-time.Each of these programming modes has a different reset set-point.
○ Sherpa Monobloc permits the production of hot domestic water with the contact of the thermostat on board the boiler; this function requires installation of the three-way valve kit for domestic hot water (optional).
○ The following functions can be remote controlled with free contacts:• switching on/off,• heating or cooling mode,• activation of the second set-point (Eco mode),• frequency limitation of the compressor,• production of domestic hot water.
○ Sherpa Monobloc can activate an auxiliary external heat source (e.g. heater) to substitute operation of the heat pump unit, in relation to the outdoor air temperature. This function requires installation of the outdoor air temperature probe kit (optional).
○ The following accessories are available:• Code B0622 - Three-way valve kit for domestic hot water,• Code B0623 - Outdoor air temperature probe kit,• Code B0812 - Remote control kit.
The codes are subject to change; please contact Olimpia Splendid for further information.

Check that the pressure losses of the system guarantee the required flow of water (see para. 2.4.3). If greater heads are required due to high pressure losses in the system, an inertial vessel or a hydraulic
separator and an external idle pump must be added. The system must have a minimum water content required to ensure good system operation. If it is insufficient, add a storage vessel in order to reach the required content.The water distribution pipes must be suitably insulated with expanded polyethylene or similar materials. The on/off valves, bends and unions must also be suitably insulated. To prevent air locks inside the cir-cuit, insert automatic or manual breather devices at all the points (high pipes, traps etc.) where air may accumulate.

2.4.8.2 POSITIONING
Install the unit on a solid base that is able to take its weight; if installed incompletely or on an inappropriate base, the unit could detach itself and cause damage to property or physical injury.
It is very important that the installation place be chosen with extreme care in order to ensure adequate protection of the device against impact or possible consequential damage. Choose a place that is ade-quately ventilated and in which the outdoor temperature in summer does not exceed 46°C.
Leave sufficient clearance around the appliance in order to avoid the recirculation of air and to facilitate maintenance (see Fig. 65).
Prepare a layer of gravel underneath the appliance for drainage of the defrost water.Leave space underneath the unit to prevent the defrost water from freezing. In normal situa-tions, ensure the base is at least 5 cm off the ground; for use in regions with very cold winters, en-sure a space of at least 15 cm on both sides of the unit. When installed in a location with high snow fall, mount the support of the appliance at a height that is above the maximum level of snow. Install the unit so that wind is not blowing across it.
Also prepare: ○ anti-vibration dampers; ○ compliant power supply near the unit.

2.4.9 INSTALLATION To ensure successful installation and optimal performance, follow the instructions in the installation, use
and maintenance manual supplied with each unit and accessory. This technical booklet provides general information on installation, dimensional drawings and wiring diagrams.
The installation must be carried out by the dealer or by other qualified personnel; if the installation is not carried out correctly, there may be a risk of water leakage, electric shock or fire.
During assembly and any maintenance operation, observe the precautions in the installation, use and maintenance manuals and on the labels inside the appliances, and take any precautions dictated by common sense and set down by the safety rules at the place of installation.
Always wear protective gloves and goggles when performing maintenance on the parts of the appliances
containing refrigerant. Air-water heat pumps MUST NEVER be installed in rooms where there is inflam-mable gas, explosive gas, a high level of humidity (laundry rooms, greenhouses etc.), or in rooms where there are other machines generating a lot of heat.
It is recommended to use only the components designed specially for the installation provided; the use of different components could cause the leakage of water, electric shock or fire.
Once the installation has been completed, check that there is no leakage of refrigerant (the liquid can produce toxic gas when exposed to flames).
When installing or relocating the system, make sure that there is no substance in the refrigerant circuit other than the refrigerant specified in the technical data (see para. 2.4.3) as the presence of air or other foreign substances in the refrigerant circuit can cause an abnormal increase in pressure or breakage of the system, resulting in damage to property or physical injury.

2.4.9.1 HYDRAULIC CONNECTION
The hydraulic connections of the plate exchanger must be done using all the components necessary and materials that can guarantee the water-tightness of the threaded joints.
The hydraulic circuit must, in any case, be set up following these recommendations: ○ The external circulator, when applicable, must be installed on the return pipe immediately upstream
of the head pump (unit without hydraulic circuit). ○ It is advisable to fit on/off valves for isolating the main components of the system and the exchanger.
These valves, which can be ball, globe or butterfly valves, must be sized to ensure the least possible pressure loss when fully open.
○ The system must be equipped with a drainage system at its lowest point. ○ There must be air vents at the highest point of the system. ○ Pressure connections and pressure gauges must be installed upstream and downstream of the ad-
ditional pump, when applicable. ○ All the pipes must be insulated and supported in an appropriate manner.
The following measures must be taken: ○ The presence of solid particles in water can cause clogging of the exchanger. A removable mesh filter
must be fitted, therefore, at the inlet of the exchanger. The holes in the mesh filter must measure a minimum of 10 mesh/cm2.
○ After assembly of the system and after any repairs, it is essential to clean the entire system with care and check the state of the filter in particular.
○ It is necessary to mount a control valve on the delivery pipe during installation for regulating the flow of the pump.
○ In the case of cooling water at a temperature below 5°C, or if the appliance is installed in an area where the temperature is prone to dropping below 0°C, it is essential to mix water with an appropriate amount of inhibited monoethylene glycol.
Do not use the heat pump for industrial process water, swimming pool water or domestic water. In all these cases, use an intermediate heat exchanger.
The tables below (Tab. 200, Tab. 201, Tab. 202 and Tab. 203) show the essential characteristics of the hydraulic system.

For 3Ph units, make sure to apply the ferrite supplied on the power cable to guarantee compliance with the EMC standards (see para. 2.4.9.3).
The Sherpa Monobloc units can pilot a 3-way valve for managing a domestic water storage tank. The operating logic is such that, when a storage tank requires domestic water, the system controls a 3-way valve to direct hot water only to the tank and runs at full capacity to supply water at 60 °C (in accordance with the operating limits).
For operation, connect the 3-way valve to PIN 18, N and 10 of the terminal board (see para. 2.4.9.3). PIN 18 (Line) and N (Neutral) supply power to the valve (1ph ~ 230V, 2A max), while the control signal is available at PIN 10 (1ph ~ 230V, 2A max). If using a valve with spring return, connect only PIN 10 and N.
The DHW request signal must be of the Dry Contact type (quality of the contacts greater than 25mA @ 12V) that closes the circuit between PIN 15 and PIN 13 of the terminal (see para. 2.4.9.3).
The request for domestic water takes priority over the programmed operating mode, whether heating or cooling.

3.3 AQUADUE CONTROL3.3.1 INTRODUCTION
AQUADUE CONTROL is for the supervision and control of hydronic systems for cooling and heating rooms and the production of domestic hot water.The control can manage each room locally while also offering all the benefits of centralized integration and supervision, even remotely. It permits the control, configuration and monitoring of each unit indi-vidually or arranged in groups and rooms. Programming can be manual or according to time band and scenario.
3.3.2 COMPONENTSAQUADUE CONTROL consists of the CPU and pre-installed Olimpia Splendid application.
The CPU has Ethernet ports for connection to a personal computer, an existing TCP/IP network, a rout-er/switch for remote management with PC or smart phone, or the AQUADUE TOUCH 7" touch screen.
3.3.3 FUNCTIONS ○ AQUADUE CONTROL can manage fan coils, heat pumps and wall-mounted thermostats. ○ It autonomously identifies the units of the system to establish a connection with each one and sorts them
according to type and room. It can also group them and rename them according to the User's needs. ○ It can control each unit individually or according to room. ○ It displays the operating mode and conditions, and any alarm states. ○ It offers all the functions of the fan coil and wall-mounted thermostat, with the additional options of a
supervisor that can force operating modes or introduce set-point restrictions that the machine User must observe, or modify the operating parameters.
○ It offers a weekly Timer with Manual control. ○ Contacts on the CPU permit simple and effective interconnection with other systems. ○ A BACnet module can be integrated on request. ○ Configurable password protection permits different levels of access. For small applications, simple su-
pervisor access is also possible without the need for entering codes.

SHERPAHEAT PUMPS
3.3.4 CONNECTIONS All the units, whether fan coils, heat pumps or thermostats, can be connected to the CPU with a common two-core cable for data lines, RS485 interface and MODBUS protocol. Each unit is assigned a unique address to permit identification on the network irrespective of its point of connection.
3.3.5 UNITThe base configuration of AQUADUE CONTROL can manage up to 32 units. The number can be in-creased to 192 with appropriate expansions or, with 5 interconnected CPUs, up to about 1000 units.
The Bi2 and Bi2+ SMART 2- or 4-tube fan coil units can be equipped with the usual B0371 or B0374 type complete control panels instead of additional accessories.The heat pump units can be Sherpa or Aquadue, or both, up to a maximum of ten.The wall-mounted B0736 LCD thermostat can, in turn, manage up to 32 sub-units (equipped with B0372 or B0375 type on-board panels) and increases the total number of units that can be managed ten-fold.
3.3.6 SMART PHONEThere are APPs for iOS and Android that permit access to AQUADUE even on your smart phone.
