Special function: Humidity control
The humidity in the stall can be controlled by a combined humidity / temperature sensor of the MFTG-
100V type (Art. No. 384033).
On activating the humidity control in the Installation menu a separate control circuit becomes active
which acts on the same output as the control circuit for the temperature-dependent regulation. The
respective higher control (temperature or humidity-dependent) acts on the output for the fan or shutter
(in central exhaust air systems).
If the stall temperature is reduced below the temperature setpoint of the ventilation by the in
uence of
the humidity control, the humidity in
uence is reduced within an adjustable range (
“
Humidity cooling
”
in the Installation menu) linearly to
“
0

Information
A heater is requiredin the stall for a perfectly working humidity control!
Note!
Due to the in
uence of the humidity control the stall temperature can drop below the temperature
setpoint of the ventilation andthe heating may be activated. To avoidtoo great an in
uence from the
humidity, the
“

can be set in the installation menu. Within the adjustable range,
the humidity control is reduced linearly to
