Shutting down the heat pump

The heat pump must be shut down in certain situations, for example
during any intervention on the equipment. In other situations, such as an
extended absence period, we recommend that the System holiday mode
operating mode is used in order to benefit from the heat pump anti-
blocking function and to protect the installation from frost.
To shut down the heat pump:
1. Switch off the outdoor unit and the indoor unit.
