The heat pump switches off at approx. – 20 °C or +35 °C. The indoor
unit or an external heat source then take over the heating and DHW
heating. The heat pump restarts if the outdoor temperature exceeds
roughly – 17 °C or falls below +32 °C. In cooling mode the heat pump
switches off at roughly +45 °C and restarts at roughly +42 °C.
