7.15.6 Simultaneous humidity and temperature control
With simultaneous humidity and temperature control, humidity control is generally independent of temperature control. Hu-
midity control can be restricted to within a well-defi ned temperature range (parameters TLL and THL and the corresponding
diff erential TdL), so as not to risk excessive temperature drift during humidity control.
Par. Description Def Min Max UOM User User terminal
TLL Minimum temperature to enable humidity control 0 -60/-76 60/140 °C/°F S NO
THL Maximum temperature to enable humidity control 0 -60/-76 60/140 °C/°F S NO
TdL Diff erential to enable humidity control 0 0 20/36 °C/°F U NO
Notice: if parameters TLL and/or THL are set to 0, they are ignored for control purposes
Case 1: Humidity control
independent of temperature (default)
The temperature is only controlled after the humidity
reaches the set point. This is the default setting, with TLL
and THL = 0

Case 2: Humidity control
within a set range
Priority is given to temperature control: humidity is con-
trolled in a series of cycles, while always keeping
the temperature in the range TLL-THL.

Case 3: Humidity control
with high temperature limit
This confi guration prevents the
temperature from exceeding the limit (THL) during
dehumidifi cation, for example if the
heater is oversized.

Case 4: Humidity control
with low temperature limit
This confi guration allows humidifi cation
to be stopped below the threshold TLL threshold
to avoid excessive cooling and lowering the tempera-
ture, for example if the heater is undersized.

7.15.7 Humidity probe error
In the event of a humidity probe error, humidifi cation and dehumidifi cation are managed in duty cycles. This is only possible for
humidifi cation alone and dehumidifi cation alone; with dead band control, both outputs remain off .
