With the display on, if the functions cannot be accessed by pressing the keys, put the

equipment in stand-by, disconnect voltage and access the electronic card

Make sure there is no oxide on the flat cable terminals. If necessary, remove the oxide

Give power again and make sure there are 230V +/-10% between

the “L” and “N” “faston” type terminals



see wiring diagram

Check that the power supply voltage at transformer output (12VDC) is stable

If it is still not possible to access the functions, press the keys



replace the electronic board
