AUTO mode
After the IHC is connected to the Connect-App, the system switches to AUTO mode. In AUTO mode, the system automatically
changes between Eco and Comfort mode at predefined times according to a defined weekly programme.
The AUTO mode can only be activated / deactivated in the Connect-App under "Setting" → "State".
If the IHC is set to standby or frost protection mode, the AUTO mode is stopped. To return to AUTO mode, simply select eco or comfort
mode locally on the IHC.
In AUTO mode, some changes made on the IHC are only temporary (so called "override"). These temporary changes are also
indicated in the Connect-App.
Temperature override
The room temperature can still be changed manually on IHC in AUTO mode. If the set room temperature is different to the one defined
within the weekly programme, the new room temperature is only applied until the next switch eco mode ↔ comfort mode according
the weekly program.
To permanently change the room temperature in AUTO mode, please use the Connect-App.
Heating mode override
Switching locally on IHC from eco to comfort mode or vice-versa in AUTO mode is again only a temporary change which is applied only
until the next change according the defined weekly program. Switching to frost protection or standby mode is applied permanently and the
AUTO mode is stopped.
