CONNECTION PRINCIPLE OF THE
INTERNAL UNIT
The principle method of operation is based on the
vapour compression cycle with any additional heat being
provided by the built in electric heater. The control unit
regulates the heat pump in accordance with the set
heating curve with the actual temperatures captured by
outside temperature sensor T2 and flow temperature
sensor T1.
When the heat pump can no longer meet the entire
heating demand on its own, the electric additional heat
in the internal unit starts and generates the temperature
required inside the building together with the heat
pump.
DHW heating has priority. DHW is regulated by means of
the actual temperature captured by cylinder
temperature sensor T3. Heating is switched off via the 3-
way valve when the DHW cylinder is being heated up.
The heating system will be supplied with heating water
again once the DHW cylinder has reached its set
temperature.
Operation in extreme cold conditions:
At an outside temperatures below approx. – 20 °C, the
heat pump stops automatically and can no longer heat
DHW. Under those conditions, the additional electric
heater in the internal unit automatically takes over the
DHW heating.
