Function
Heat is extracted from the outside air
at temperatures ranging from +35 °C
to –20 °C by the heat exchanger
on the air side (evaporator) of the
external unit. Heating water is
heated to flow temperature levels
in the heat exchanger on the water
side (condenser) by this extracted
heat and additional heat from
the electrical power used by the
compressor. At air temperatures
below approx. +7 °C, the humidity
in the air precipitates as hoarfrost
on the evaporator fins. Any hoarfrost
is automatically defrosted. water
created from this defrosting is caught
as well as in the defrost pan below
the external unit and is drained off.
Appliance description
Air | water heat pump system with
little space requirement, comprising
a heat pump for external installation
and a cylinder module for internal
installation. the heat pump is
suitable for external installation
and is connected electrically and
hydraulically with the cylinder
module. the cylinder module
consists of a 200 litre enamelled
DHw cylinder and the integral
heat pump manager. the required
circulation pumps for heating and
DHw as well as the booster heater
for mono-energetic mode are built in
as standard. the heat pump is filled
with refrigerant r410A. the heat
pump is controlled via a bUs cable.
