: Overall description
When the dehumidifier is started by the hygrostat, the fan(s) are activated at the same time as
the compressor.
In order to check the humidity level the units are starting the fan(s) once an hour for one
minute (
NOTE: only applicable to CDP 40T-50T-70T units
):
•
If the humidity is above the selected setpoint, the unit starts dehumidifying.
•
If the humidity is below the setpoint, the unit will remain off and check the humidity
level again after one hour.
To protect the compressor against overloading there is a timer which prevents the dehu-
midifier from starting more than 10 times pr hour. It means, that there is at least 6 minutes
between every start up.
This unit is equipped with an intelligent defrosting strategy.
The unit monitors the temperature of the evaporator, and when the temperature has been
below a certain temperature for a period of time, the dehumidifier will switch to active
defrosting, the fans will stop, and the magnetic valve will open.
The hot gas can now pass through the evaporator.
When the evaporator has the right temperature again the magnet valve will close and the
dehumidification will continue.
If the temperature in the dehumidifier increases to a temperature of more than 55 °C (in case
of fan failure or room air temperature higher than 36 °C), the compressor stops automatically
to avoid damaging it. When the temperature allows it the dehumidification will continue.

Two cable grooves for accessory make it
easy to guide the cables from the control
panel to the mains electricity connection
and out of the unit.
Groove B is for use with cable from ex-
ternal RH sensor as it requires a seperate
groove to avoid interference.
All other accessory cables are to be
placed in groove A1-A2.
An LED is placed at the front of the unit. The LED light
indicates different modes of the unit.
Find a description of the different modes in section
“LED light and troubleshooting” on page 28.
