Commissioning

Caution! The installation may only be commissioned if the heating system is filled and bled. Otherwise the

circulation pump can be damaged.

Caution! If the installation is only to operate using an auxiliary heater during the installation, ensure that

the heating system is filled and bled and that the compressor cannot be started. This is carried out by

setting the operating mode to AUX. HEATER.
