900 1200 Optg mode changeover
(None / Frost protection mode / Reduced / Comfort / Automatic)
In case of an external changeover via input H2 (on the extension module only) the operating mode to which the
changeover will be performed must be previously defined.
Heating Circuit Frost Protection
The heating circuit frost protection is continuously
activated (protection mode
) and is not adjustable.
Heating circuit frost protection in heating mode
If the flow temperature is below 5°C, the controller
initiates the production of heat and starts the heating
pumps, regardless of the current heating mode.
If the flow temperature rises again above 7°C, the
controller waits another 5 minutes, and then stops the
production of heat and the heating pumps.
