GENERAL FEATURES

Unit description

This series of air-water heat pumps satisfies the heating, coo-ling and domestic hot water production requirements of residen-tial plants of small and medium size.All the units are suitable both for outdoor or indoor installation. The possibiliy to produce water at high temperatures makes the-se 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 do-mestic hot water management. The possibility of solar panels or other heating sources integration is also available.The heating function optimizes the flow water temperature ac-cording both to the ambient temperature and to the outdoor tem-perature through climatic curves adaptable to the building featu-res. 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 th-ree 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 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 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 pla-te heat exchangers, electronic expansion valve, reverse cycle valve, centrifugal fan (plug fan), finned coil realized with cop-per 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 ther-mally insulated in order to avoid condensate generation and re-duce thermal losses.The plug fan with electronic control of the rotational speed gua-rantees high efficiencies and low noise in all the operating con-ditions 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 clima-tic control.All the units are accurately built and individually tested in the factory. Only electric and hydraulic connections are required for installation.

re (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- 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 user interface of the unit to be placed indoor, wi-red 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 so-lutions 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 fulfil a complete system.
