3.9 Indications
Open window detection
If the IHC is in eco or comfort mode and detects a rapid drop in temperature due to opening a window or door to a cold room, the
system automatically switches to frost protection mode to safe energy.
The open window detection is indicated on the RCE by a blinking frost protection icon.
If the IHC detects that the window or door has been closed, the system automatically switches back to the last selected heating mode.
Alternatively, an active open window mode can also be stopped manually by pressing the mode button on the RCE.
