Instructions for use:
1. Commissioning
Insert the mains plug properly into the socket.
Switch on the unit with the "On/Off switch".
Now set your desired target humidity value between 30% and 90% or select continuous operation. To do this, press
the "button for lowering the target humidity value" (▼) or the "button for increasing the target humidity value" (▲),
as appropriate. Pressing briefly changes the target humidity value by 1% each time. By pressing and holding (1.5
sec.), the target humidity value can be set by fast forwarding.
A target value of below 30% humidity is indicated in the display with "CO" and signals that the building dryer is now
set to continuous operation !!!
After approx. 5 seconds of inactivity, the target humidity value goes out and the currently determined room humidity
is shown in the display.
Note: The construction dryer has an automatic memory function. In the event of a power failure, this function
ensures that the building dryer resumes operation where it was previously interrupted. All set values remain stored.
To protect the compressor, however, its switch-on process is delayed by approx. 3 minutes ! (Compressor light
flashes during this time).
2. Operating procedure
After the building dryer is properly connected to the socket, the backlight of the display panel lights up.
After switching on the unit (On/Off), the detail display in the control panel lights up automatically. The target
humidity value is already preset to 60% r.l. by default.
The unit is programmed so that the compressor switches on for dehumidification as soon as the selected target
humidity value has been exceeded by 3% points (of the current room value).
The compressor then switches off again automatically as soon as the target humidity value has been undershot by
3% points. The compressor is then switched on again in the same way, so that there is a tolerance of 6% points
between the automatic switch-on and switch-off.
After switching off the unit (On/Off), all functions switch off and all displays go out.
3. Operating instructions
If the current humidity is below the target humidity value, the unit does not switch on.
To protect the compressor, the unit should always run for at least 3 minutes or be switched off before you press the
On/Off switch again!
At cold ambient temperatures or icing in the unit, a sensor automatically controls a defrosting process. This is
indicated by the following defrost symbol ( in the display field at the top right). Meanwhile, the defrost mode
automatically controls the air circulation and the compressor operation!
4. Error codes / display indication
"E1" or "E3" The humidity sensor cannot determine a measurable value or the determined value is outside the
displayable range (below 30% or above 90%) or the sensor is damaged. (In this case, please contact your
specialist dealer).
"E2" or "E5" The defrost sensor cannot determine a value. (Please contact your specialist dealer if necessary).
"E4" There is a problem with the water tank. Check the water tank, if the problem persists, please contact your
dealer.
