6 Selector dial positions in diagnostics
The alarms are enabled during diagnostic testing of components. If an alarm appears, move the selector to
the first position to exit the alarm status and, if necessary, continue the test (if the alarm is not triggered
again).
To check the correct functioning of the float switch and pump, the trap should be filled with approximately
0.7 litres of water.
In order to test the conductivity sensor properly in case of a short-circuit (position 8), a short circuit must be
created between the two sensors on the front air conduit before moving the selector dial to the eighth
position. If the short-circuit is not created properly, the circuit board will display alarm E32 (sensor frequency
too low). To exit this alarm, move the selector to the first position.

To test the functionality of all LEDs and switches
All LEDs.
LCD display.
All LEDs flash in sequence.
Press a button and the corresponding LED is lit;
the code is shown on the LCD display and the
buzzer sounds.
All LCD icons flash simultaneously
there is a control to run the test (always active).
To test the pump and micro-switch situated in
the condensation water tray
It the condensation water collection tray is full
and the micro-switch detects this condition, the
pump is started.
If the water level in the tray is low, the LCD
displays III and if the level is high (micro-switch
triggered), the LCD displays 000
door closed (timeout 10 secs.).
