SENSORS
The electronic board receives the controls relative to the drying cycle setting through the control/display

section), heater and door interlock.
The board also controls the door interlock, the temperature of the air inside the dryer (using an NTC
sensor), the level of humidity of the washing (using a conductimetric sensor) and the level of
condensation water in the canister.
The programme selector and the buzzer are incorporated in the main board.
