In AUTO mode, some changes made on the IHC or RCE are only temporary (so called "override").
Temperature override
The room temperature can still be changed manually on RCE or 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 of eco mode ↔ comfort mode accor-
ding the weekly program.
The temporary room temperature is indicated on the RCE by the override icon lightning up.
The override icon disappears if the selected room temperature matches the current room temperature defined in the weekly program.
To permanently change the room temperature in AUTO mode, please use the Connect App.
Heating mode override
Switching on RCE or 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.

Ensure the IHC is turned on and in operation.
Check the distance between the remote con-

IHC, the connection should be re-established
automatically. If error occurs again, reset the
RCE and perform again the pairing process
with the IHC.
Reset the RCE or briefly remove the batte-
ries. If error occurs again, contact customer
