4. ELECTRONIC CONTROL AND FUNCTIONING
The electronic board installed on the model FSW63 is connected directly to the power outlet of the machine. It is equipped
with three temperature probes and a humidistat.
The electronic control unit, by means humidistat that measures the relative humidity in the environment, makes the machine
works in order to achieve the degree of humidity wanted.
When the temperature reached by the finned coil is too low the electronic control unit starts a defrost cycle to melt the ice
formed in the finned coil.
This unit is programmed to stop the dehumidifier if the temperature drops below 4.5 ° C.
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:
when the heating function is activated, the LED pulses every 10 seconds, when the
heating element is powered the LED remains lit.
; 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.
; 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.
Full LED; this LED is lit when the condensate tank is full.
; the machine has the possibility of using a remote humidistat or switch.
For this purpose, it needs to change the set in the PCB: with plug inserted in the socket, put the
machine in OFF position, then press all together these 3 buttons for 4 seconds: HOUR
COUNTER, SET UP and SET LOW , the machine changes and led REMOTE turn on. Pay
attention that if the humidity is set in cont position, machine works not considering the remote
control.
Remote LED; lights up when the machine is controlled remotely.
