Whenever the system detects an error, the message “Err” will be displayed in the zone where
the error has occurred. To consult the relevant error code, press “Err” when it appears.
Errors 1 and 2 have a blocking effect, and if either of them appears the thermostat cannot be
used until the error has been fixed. For the other errors, the letters “Err” will appear on the hour
digits. Pressing them displays the error code on the temperature digits.
Press the Airzone icon to clear the error and return to normal mode.
The grille and sensor errors (3, 4, 5 and 6) will only appear if these components have been set
up (the grille is set up by default and the sensor not).
