If the unit is switched on and off repeatedly on the main switch the LED's will light up one by one in green before
the actual mode is shown on the display.
Lightning – constant green- (1)
The LED lights up in green when power is connected to the unit
Drop – constant green- (2)
The LED lights up constantly in green when the compressor is in operation and the unit is in dehumidification
mode.
Failure on the low-pressure pressostat
Lightning – constant green + Drop – flashes on and off in green + Triangle – constant red (1) (2)(3)
A constantly green Lightning indicates that power is on. The Drop and the Triangle LEDs flash on and off in green
and lights up constantly in red, respectively, to indicate that there has been a failure on the unit by the low-pressure
pressostat. If the low-pressure pressostat registers a too low pressure in the cooling circuit, caused by a too low
temperature across the evaporator, the unit will be stopped until the required pressure has been reestablished and
the low-pressure pressostat then switches on the unit again.
When the unit has been switched on again, the Triangle light goes out and the Drop continues to flash on and off in
green. The Lightning is still green.
Drop – flashing on and off in green + Lighting – constant green – (2)(1)
When the Drop flashes on and off in green and the Lighting is constant green, this indicates that the unit is working
but there has been a failure on the unit through the LP pressostat.
The flashing Drop is switched off by turning the unit OFF and ON on the main switch.
