Signalling panel
Units are provided with signalling light panel that indicates unit operational status. Below is reported a brief
description of their meaning.
Control panel
The Electronic card with microprocessor, control many functions:
Power LED
; it’s on when the machine is in the ON state.
Alarm LED
; it’s on when an alarm comes on. It turns off if the alarm is reset.
Working LED
; the LED is on when the compressor is running, blinks when the dehumidifier is
waiting to restart or is in defrost. It’s switched off when, in the ON state, the set of desired
humidity has been reached.
ON/OFF function
; plugged into the outlet (with ground wire!), the display turns on and shows the
relative humidity in the room.
The machine is in the OFF state when the Power LED is off. It’s in the ON state when the Power LED
is on.
When OFF, to switch on the dehumidifier, simply press the POWER key and depending on the
relative humidity set the machine starts working.
When the machine reaches the level of required moisture goes into stand-by mode: automatically
stops but remains in the ON state (POWER LED on).
If the humidity goes above the set point the dehumidifier starts again.
When ON to put the dehumidifier in OFF just press the POWER button (the display continues to
indicate the humidity in the room).
Note: putting the machine OFF and immediately ON, the compressor does not start immediately and
the Run led starts to flash. After a time of 210 seconds the machine restarts.
HUMIDITY/TEMPERATURE SET function
; press one of the SET-/ +: the display starts flashing to
indicate the humidity set; continuing to press SET-/ + you can bring to the set of required moisture
(from 30% to 80%). After 4 seconds the display stops flashing and the new set of moisture is
detected by the control unit.
It’s possible to make the machine works regardless of the degree of moisture holding SET- until the
message "Cont" appears.
HOUR COUNTER
: to show on the display the machine operating time push switch HOURS.
