GENERAL FEATURES Unit description This series of air-water heat pumps satisfies the heating, coo- The refrigerant circuit, contained in a box repaired from the air ling and domestic hot water production requirements of autono- flow to simplify the maintenance operations, is equipped with mous or centralized residential plants of medium and large size.
GENERAL FEATURES Description of components External structure . Basement, supporting structure and lateral (6) to allow operating mode change reversing the refrigerant panels are made of galvanized and painted sheet-steel to flow, liquid receiver (7) to compensate the different refrigerant guarantee good resistance to atmospheric agents.
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 temperatu- 18:28 re (climatic control)
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 “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. The anti legionella cycles have to be performed by means of electrical heaters placed on the heat pump outlet (see option “Integrative electrical heaters”) or...
