This series of water-water heat pumps satises the heating, cooling and domestic hot water production requirements of autonomous or centralized residential plants of medium and large size.

All the units are suitable for indoor installation and can be applied to fan coil plants, radiant oor plants and high efciency radiators plants.

As source both water (from well, river, lake…) or brine solutions (from geothermic probes) can be used.

The control system allows to manage not only the refrigerant circuit but the whole plant with the possibility to choose different solutions both for the heating and cooling plant and for the domestic hot water management. The possibility of solar panels or other heating sources integration is also available.

The heating function optimizes the ow water temperature according both to the ambient temperature and to the outdoor temperature through climatic curves adaptable to the building features. It’s possible to manage a storage tank and two independent circuits (a direct one and a mixed one).

The domestic hot water management allows to control the three way valve, the storage tank and the anti-legionella cycles (if necessary).

The cooling function can be realized through “passive cooling” (free cooling), through “active cooling” (refrigerant circuit inversion) or through both systems actuated in sequence. When the unit is used in radiant oor plants, to avoid condensate gene-

ration, a room humidity sensor can be installed. During cooling mode operation a part of the heating power in excess can be recovered for the domestic hot water production (VD version).

The internal programmer clock allows to dene different daily switching programs for heating, cooling and domestic hot water production.

The refrigerant circuit is equipped with scroll compressor mounted on damper supports, brazed plate heat exchangers, electronic expansion valve and reverse cycle valve (for reversible units). The circuit is protected by high and low pressure

switches and ow switches on both the exchangers.

In the low noise setting up units (AS) the outdoor structure is thermally and acoustically insulated in order to reduce sound propagation and to allow the installation in domestic places.

All the hydraulic pipes are thermally insulated to avoid condensate generation.

All the units are supplied with phase sequence and voltage controller and with an outdoor temperature sensor in order to realize the climatic control.

All the units are accurately built and individually tested in the factory. Only electric and hydraulic connections are required for installation.

GENERAL FEATURES

Description of components

External structure. Basement, supporting structure and panels

are made of galvanized and painted sheet-steel to guarantee good resistance to atmospheric agents. Accessibility to internal parts is possible removing the frontal and lateral panels. For extraordinary manteinances also the rear panel can be removed.

In the units with low noise acoustic setting up the basement, the supporting structure and the panels are completely insulated in order to minimize noise emissions in the surroundings.

Refrigerant circuit. It is contained inside a compartment easily accessible to simplify maintenance and control operations.

The hermetic scroll compressor (1) is mounted on damper supports and is protected against overtemperatures and overcurrents.

The heat exchangers on the plant side (2) and on the source side (3) are realized with brazed stainless steel plates, properly insulated to avoid condensate generation and to minimize thermal losses, and protected by a flow switch that detects whatever water flow lack. The expansion device (4), an electronic expansion valve, allows the unit to adjust itself to the different operating conditions keeping steady the set superheating. The refrigerant circuit of each unit contains moreover solid core hermetic filter dryer (5) to restrain impurity and moisture residuals that could be present in the circuit, high and low pressure switches in order to assure the compressor to operate inside the permitted limits, 4 way reverse cycle valve (6) to allow operating mode change reversing the refrigerant flow (only for reversible heat pumps), pressure connections SAE 5/16” - UNF 1/2” - 20 equipped with pin, gasket and blind nut, as required for the use of R410A refrigerant (they allow the complete check of the refrigerant circuit : compressor inlet pressure, compressor outlet pressure, thermostatic expansion valve upstream pressure and pressure drops accross the filter). All the pipes of the refrigerant

circuit are properly insulated to avoid condensate generation and to minimize thermal losses.

Hydraulic circuit. Both the hydraulic circuits on the plant side and on the source side are equipped with expansion vessel, air vents and drain valves. The circuit on the plant side is moreover equipped with pressure safety valve. All the pipes are thermally insulated to avoid condensate generation and minimize thermal losses. The circuit on the plant side can be equipped with a circulation pump (option) while the circuit on the source side can be equipped with a circulation pump (option) or with a two way valve (option).

Electrical panel. It contains all the power, control and security components necessary to guarantee the unit to work properly. The unit is managed by a microprocessor controller to which all the electrical loads and the control devices are connected. The user interface, placed on the frontal part of the unit, allows to view and to modify, if necessary, all the parameters of the unit.

All the units are supplied with an outdoor temperature sensor, to be installed outside, in order to realize the climatic control.

GENERAL FEATURES

Control system

The microprocessor controller is able to manage not only the unit itself but also all that components of the plant which allow to realize a complete system.

The main functions of the control system are :

- room temperature control according to the outdoor temperature (climatic control)

- domestic hot water production (management of 3 way valve, storage tank, anti legionella cycles…)

- management of a heating and/or cooling mixed circuit (pump and 3 way mixing valve)

- management of a heating direct circuit (only pump)

- management of a storage tank for heating and/or cooling

- management of electrical heaters for heating and domestic hot water (3 steps logic)

- solar panels integration

- passive cooling

- room humidity control for cooling with radiant systems

- internal programmer clock (for heating, cooling and domestic hot water)

- digital input for electrical energy low tariff

- alarm memory management and diagnostic

- compressor and pump operating hour counter

- possibility to manage more units in cascade (maximum 16)

Besides the standard user interface present on all the units, wired or wireless remote thermostats are available which allow to control all the operating parameters of the unit and to acquire the temperature in the different zones in order to realize a more precise and comfortable control.

The unit controller is able to manage a lot of different plant solutions enabling automatically the necessary control algorythms according to the components which have been connected.

The management of such components is possible through additional expansion modules which communicate with the unit by means of an internal bus and provide all the inputs and outputs

required to full a complete system.

The controller is able to manage up to two zones in heating (one by means of a mixed circuit and the other by means of a direct circuit) and one zone in cooling (by means of a mixed circuit).

It’s possible to realize more complex plants connecting to the heat pump controller further expansion modules in order to extend without limits the number of zones to be managed.

For each zone the following parameters can be set :

- set point

- daily or weekly operating time table

- climatic control curve

- room control sensor : it can be in common with the other zones or independent (in that case it’s necessary to install an additional room thermostat)
