4.2 Selection of the operating mode

Actuating the touch key "Mode" allows to change the operating mode
in the order shown below:
– Automatic mode (in compliance with the related weekday mode settings)
– Comfort mode, permanently
– ECO mode, permanently
– Operating mode "OFF"
In "OFF" mode, the controller activates the heating when underrunning a temperature
level of approx. 5°C and deactivates the operations when exceeding a temperature level
of approx. 6°C. This antifreezing function helps prevent rooms from cooling down
thoroughly and protects against the occurrence of frost damage.
