Open window function

Conditions of open window detection:
The thermostat detects an "Open window" if the displayed
temperature (internal or ambient sensor) decreases by 3°C
or more during a 5 minutes period (or less).
In this case, the thermostats stops heating for 15 minutes.
The function remains active during those 15 minutes so the
stop can last more time if the temperature continues
decreasing.
As an indicator of this function, the room temperature will
blink.
Return to normal mode:
The thermostat returns automatically to normal mode after
the stop period.
The function can be overridden by pressing the (OK)
button during the stop heating phase.
Then the blinking temperature should stop to indicate the
end of the detection.
Special cases:
- This function doesn't work if Thermostat is in Floor
regulation
- This function doesn't work if Thermostat is in OFF /
Antifreeze Mode
- If temperature is less than 10°C, thermostat will regulates
at 10°C during the stop phase
