Functional principle
The function is based on the demand-actuated control of the compressor
output and, if needed, by switching on the integrated electric booster
heater via the indoor unit. The control unit controls the outdoor unit
depending on the set heating curve.
If the outdoor unit is unable to satisfy the heat energy demand of the
house, the indoor unit automatically starts the integrated electric
booster heater which produces the desired temperature in the house
together with the outdoor unit.
The DHW heating is controlled via the TW1 sensor in the DHW cylinder.
During the heat-up phase of the DHW cylinder, the heating mode of the
heating system is temporarily switched off via a 3-way valve. Once the
DHW cylinder is heated up, heating mode is resumed by the outdoor
unit.
Heating and DHW mode when the outdoor unit is deactivated
When the outdoor temperature is below –20 °C (approximately) or
exceeds 45 °C (approximately), the outdoor unit is automatically turned
off and is unable to produce any heat. In this case, the integrated electric
booster heater of the indoor unit adopts the heating and DHW mode.
