This series of 

water-water

  heat  pumps  satisfies  the  heating, 

cooling and domestic hot water production requirements of au-

tonomous or centralized residential plants of medium and large 

size.
All the units are suitable for indoor installation and can be ap-

plied to 

fan coil

 plants, 

radiant

 floor plants and high efficiency 

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 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 “passive cooling” 

(free cooling), through “active cooling” (refrigerant circuit inver-

sion) or through both systems actuated in sequence. When the 

unit is used in radiant floor 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 define 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 rever-

sible units). The circuit is protected by high and low pressure 

switches and flow 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 conden-

sate generation.
All the units are supplied with phase sequence and voltage con-

troller 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.
