Shutting down the boiler

The boiler must be shut down in order for certain operations to be carried
out on the equipment or its environment.
In other situations, such as an extended absence period we recommend
that Holiday Mode mode is used in order to benefit from the heating pump
anti-blocking function and to protect the installation from frost.
To shut down the boiler:
1. Press the on/off switch.
