Product information

Your air source heat pump consists of an indoor unit
and an outdoor unit.
The indoor unit, including the heat pump control unit, is
inside the building and transfers the heat to the heating
system.
The outdoor unit is installed outside the building or fit-
ted to the outside of the building. Heat is obtained from
the ambient air in the outdoor unit.
To achieve this, a fan draws the ambient air through a
heat exchanger (evaporator). In the evaporator, the
thermal energy from this ambient air is transferred to
the refrigerant circuit. Here, the temperatures neces-
sary for room heating and DHW heating are gener-
ated.
To provide room cooling, the refrigerant circuit oper-
ates in reverse mode. Heat is extracted from your
rooms and transferred to the ambient air via the evap-
orator.

Heat pump control unit

The heat pump control unit is integrated into the indoor
unit and controls all functions of your system. The con-
trol unit is operated via a 7 inch touchscreen.
Communication modules for the following functions are
integrated into the heat pump control unit:
■ Connection to a WiFi router, e.g. for remote control
via the internet with an app.
■ Direct WiFi connection to a mobile device ("access
point")

The refrigerant circuit is driven by the compressor.
Compared with the heat energy derived from the air,
the compressor only requires a small amount of electri-
cal power. This power is often provided at a favourable
tariff by your power supply utility.
Dependent upon the tariff conditions and the power
supply, your power supply utility may make short-term
interruptions to the heat pump power supply (power-
OFF), e.g. if there is high network load.
During power-OFF, the instantaneous heating water
heater built into the indoor unit can take over the heat
supply to the building. This instantaneous heating
water heater is then automatically switched on if the
heating output of the heat pump is insufficient or there
is a fault in the heat pump.
The QR code with designation "i" contains the
access data for the registration and product informa-
tion portal. This allows e.g. the 16-digit serial number
to be read out via the QR-Code.
