    This series of air-water heat pumps sati- sfies the heating, cooling and domestic hot water production requirements of residential plants of small and medium size.

    All the units are suitable both for outdoor or indoor installation. The possibiliy to produ- ce water at high temperatures makes these units particularly suitable to be applied to radiators plants as well as to fan coil plants and radiant floor plants.

    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 flow 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 inde- pendent 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 “active cooling” (refrigerant circuit inversion). When the unit is used in radiant floor plants, to avoid condensate generation, a room humidity sensor can be installed. During cooling mode operation apart of the heating power in excess can be recovered for the domestic hot water pro- duction (VD version).

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

    The refrigerant circuit, contained in a box repaired from the air flow to simplify the maintenance operations, is equipped with scroll compressor mounted on damper supports, brazed plate heat exchangers, electronic expansion valve, reverse cycle valve, centrifugal fan (plug fan), finned coil realized with copper pipes and alluminium fins. The circuit is protected by high and low pressure switches and flow switches on the plate heat exchanger.

    The compressor is equipped with vapour and liquid injection and is placed on an economized refrigerant circuit with plate heat exchanger and electronic expansion valve dedicated to the injection.

    The plate heat exchanger and all the hydraulic pipes are thermally insulated in order to avoid condensate generation and reduce thermal losses.

    The plug fan with electronic control of the rotational speed guarantees high efficiencies and low noise in all the operating conditions and allows to install the unit both outdoor (with protection caps) or indoor (with ducted air inlet and outlet). It is moreover possible to reduce the noise during the night.

    All the units with three-phase power supply are provided with a phase sequence and correct sequence controller device 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.
