Air/water heat pumps for indoor and outdoor installation, monoblock version
All components of the refrigerant circuit are installed in
a single appliance.
Heat pumps for indoor installation
The heat pump is supplied with outdoor air via an air
duct. Expelled air leaves the building via another air
duct.
The refrigerant circuit has a variable speed compres-
sor. The secondary pump, the 3-way diverter valve
"central heating/DHW heating" and the heat pump con-
trol unit are built into the heat pump.

Heat pumps for outdoor installation
The heat pump is installed outdoors. The building is
heated or cooled via the hydraulic connection lines.
These hydraulic connection lines, together with the
electrical connecting cables, are laid in the ground with
frost protection.
The heat pump control unit is located in a separate
enclosure inside the building. The hydraulic compo-
nents for distribution in the secondary circuit, such as
the secondary pump, are also installed in the building.
