For fully automatic heating
water heating up to +70 °C flow
temperature
suitable for underfloor and
radiator heating systems; low
temperature heating systems
are preferred, as these achieve a
higher coefficient of performance

made from corrosion-resistant
aluminium sheet
Compact design, therefore modest
space requirement
Contains non-combustible natural

extremely quiet operation
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 collects
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 wall mounting (wall
mounting bracket accessory 222263)
and is designed to be electrically
and hydraulically connected 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 the natural
refrigerant Co2. the heat pump is
controlled via a bUs cable.
