“St”. If there is ice on the evaporator, but the compressor stops because set point has been reached, fan
keep going until evaporator temperature is OK.
Full tank deactivation
The switch for full tank alarm can be deactivated. When the switch is open (tank missing or full) press for
3 sec UP + DOWN. When tank led blinks this function is on. The function is automatically turned off
when the switch gets closed.
Troubleshooting:
Probe alarm: when one sensor is damaged the unit buzzes for 15 sec and it shows the code “Hr”
(humidity sensor) or “tE” (evaporator sensor). “Hr” alarm can also appear when the room humidity
is below 22%, in this case as soon as the humidity raise again the alarm automatically goes off.
Low temperature alarm: if after 30 min of defrosting the evaporator temperature is still below “St”
the fan stops and the unit shows “LO” blinking. All led are off.
Self test:
Pressing at the same time for 3 sec DOWN + Hr buttons the unit follows this procedure:
Everything goes off and all led are on
Showing software release
Compressor and fan are on showing “At”
Press DOWN to show evaporator temperature
Pressing Hr to show relative humidity
To quit self test press stand by button
Set up mode:
Pressing Hr + UP for 3 sec in stand by mode only it is possible to set up the unit. Hr button allows passing
to next parameter, Hr + UP/DOWN to change the value, releasing Hr button the value is set. To quit set up
wait 10 seconds without pressing anything or turn the unit off.
