D. Installation - Ventilation
D.1.3.6.1 Increase for humidity
Path: Home> Installation> Climate> Ventilation> Conditionings> Increase for humidity
This function allows increase of ventilation rate (by reducing the Ventilation temperature Set) whenever
%RH goes beyond desired value: so the ambient is de-humidified.
For every 1% in excess of ambient humidity when the Block is activated (Maximum humidity), the
temperature Set of the Ventilation is decrease of value as set in Ventilation set decr, until a maximum
value set in Max. vent. set decr.
This reduction also applies to the Heating set.
i.e. when considering the following sets:
Ventilation = 25.0° (see par. C.1)
Maximum humidity = 65%
Ventilation set decr. = 0.2°
Max. vent. set decr. = 2.0°
Below 65% of indoor humidity (Maximum humidity) the Ventilation temperature set will be 25.0°, at
65% of indoor humidity will be 24.8° (25.0°-0.2°= 24.8°), due to decrease of 0.2° (Ventilation set
decr.) for every extra 1% of ambient humidity, up to a maximum decrease of 2.0° (Max. vent. set
decr.) which will bring temperature set of Ventilation= 23.0° at 74% of indoor humidity.
%RH value over which Dehumidification is activated, so indoor
humidity is decresed by increasing the ventilation rate.
Decrease of the temperature Ventilation set (see par. C.1) for every 1%
of % RH exceeding the Maximum humidity value.
Make sure the Ventilation different. (par. D.1.3.1.F.3) is higher or
equal to this setting.
