OPERATION
The electrical controls are located on the front of the unit. They are:
• ON / OFF Switch
0
Dehumidifier OFF
1
Dehumidifier ON
• Humidity Switch
M
Dehumidifier in continuous operation
A
Dehumidifier operation by means of an external
humidistat
• An ammeter is provided to display the current used by the unit.
• An hour counter is provided to display the total time the unit has been
in operation
• A socket is provided for connection of a external humidistat
To start the dehumidifier, turn the On / Off switch to position 1.
Turn the humidity switch to position M.
After a slight delay the fan will operate – air can be felt blowing from the air
outlets and the heater will come on.
The unit will operate continuously at this setting.
Note. The DD200 is controlled by an electronic circuit board and uses PTC
(positive temperature coefficient) heater technology to provide the heat
necessary to “reactivate” the rotor.
At switch on, the ammeter will initially show a higher current for a few
seconds, prior to settling to a steady value. This is normal.
If an external humidistat control is fitted, turn the humidity switch to position A.
Depending on the setting of the humidistat, the dehumidifier may switch off as
the relative humidity in the room decreases. As the humidity increase the unit
will automatically switch back on.
The Humidistat plug supplied should be wired using pins numbered 1 & 2.
Pin 3 is not required. See diagram 5010307 at back of manual.
