Set the setpoint for the humidity in the "B03" menu.

Also activate the electrical heaters (see section 15.3.2
"Activating the heaters").
If the value measured by the humidity sensor is higher
than the above-mentioned setpoint, the dehumidifica-
tion will be activated automatically:
– The compressor is activated to provide condensation
at the evaporator.
– The electrical heaters are deactivated only when the
air temperature is higher than the specified setpoint
(see section 15.3 "Electrical heaters").
When the return air humidity reaches the set-point, de-
humidification function is again turned off.
In order to better reach the target of humidity set-point,
it is possible to set periods of "dehumidification ON" and
"dehumidification OFF" in the mask B05, in case the
server room conditions and the required humidity set-
point are particularly critical.
Assign the desired activation and deactivation times to
the "dehumidification ON" and "dehumidification OFF"
entries in the "B05" menu, respectively.

Installation prerequisites
Any condensate that occurs is then fed to the conden-
sation tray.
Ensure that the condensate discharge is installed cor-
rectly (see section 6.3 "Connecting the condensate
discharge").
Alternatively, connect the optional condensate pump
(see section 15.5 "Condensate pump").

Condensate pump

General information
If the condensate or water from the humidifier cannot be
discharged by gravity from the condensation tray, a con-
densate pump should be installed. This condensate
pump is activated automatically by the LCP DX control-
ler when a level sensor reports the appropriate filling lev-
el in the condensation tray.

Installation
Connect the pump pipe connection (diameter ⅛"M")
with an external pipe to discharge the water of the tray.
Note:
The condensate discharge from the conden-
sate pump must not lead directly into the
drainage system without first passing
through an odour trap. The condensate
pump is not a guarantee against blockages
or emerging waste water under backpres-
sure.
