GENERAL FEATURES Unit description This series of water-water heat pumps satisfies the heating, ration, a room humidity sensor can be installed. During cooling cooling and domestic hot water production requirements of au- mode operation a part of the heating power in excess can be tonomous or centralized residential plants of medium and large recovered for the domestic hot water production (VD version).
GENERAL FEATURES Description of components External structure . Basement, supporting structure and panels circuit are properly insulated to avoid condensate generation are made of galvanized and painted sheet-steel to guarantee and to minimize thermal losses. good resistance to atmospheric agents. Accessibility to internal parts is possible removing the frontal and lateral panels.
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,...
GENERAL FEATURES Options Allows to recover a part of the available heating power (and otherwise not used Version VD - Desuperheater version during cooling operating mode) for the domestic hot water production. Acoustic Allows to reduce the noise produced by the unit by means of the refrigerant AS - Low noise acoustic setting up setting up circuit vane acoustic insulation and sound jackets on the compressors.

GENERAL FEATURES Option “Plant side flow rate management” Option “Passive cooling” Pump Option “Source side flow rate management” Pump 2 way valve Option “Domestic hot water production” 3 way valve In this configuration the heat pump can be coupled to a domestic hot water tank equipped with a coil designed for a maximum water temperature between 55°C and 60°C.
GENERAL FEATURES Accessories Allow to reduce the transmission to the unit support plane of the mechanical vibrations generated by the compressor Rubber vibration dampers and by the pumps in their normal operating mode. 3 way valve Allow to divert the hot water produced by the heat pump from the heating circuit to the domestic hot water circuit. for domestic hot water Remote thermostat Allows operating mode selection and set point adjustment.
