switched off at (set-point – Diff ON + Diff OFF): Diff ON
and Diff OFF parameters can be set in the mask Gfc30.

Dehumidification
15.4.1
General information
At installation locations where high humidity generally
prevails, there is the danger that water condenses inside
the IT cabinet. This can cause short-circuits and other
damage to the installed devices. Excessive humidity can
also lead to rust and corrosion.
To prevent this, the LCP DX can be equipped with a de-
humidification function, whereby a humidity sensor is
mounted on the inlet side of the device and a tempera-
ture sensor is mounted behind the evaporator. The
"Electrical heaters" option must also be installed (see
section 15.3 "Electrical heaters").
15.4.2
Activating the dehumidification
To activate the heaters, proceed as follows:
Assign the "YES" value to the "Enable" entry in the
"Ha30" menu.
