D.1.3.6.2 Decrease for humidity
Path: Home> Installation> Climate> Ventilation> Conditionings> Decrease for humidity
This function allows decrease of ventilation rate (by increasing the Ventilation temperature Set)
whenever %RH goes above desired value: it permits a saving on heating.
For every 1% decrease of ambient humidity when the Block is activated (Minmum humidity), the
temperature Set of the Ventilation is increase of value as set in Ventilation set incr, until a maximum
value set in Max. vent. set incr.
i.e. when considering the following sets:
Ventilation = 25.0° (see par. C.1)
Minimum humidity = 50%
Ventilation set incr. = 0.2°
Max. vent. set incr. = 2.0°
Above 50% of indoor humidity (Minimum humidity) the Ventilation temperature set will be 25.0°, at
50% of indoor humidity will be 25.2° (25.0°+0.2°= 25.2°), due to increase of 0.2° (Ventilation set
incr.) for every 1% decrease of ambient humidity, up to a maximum increase of 2.0° (Max. vent. set
incr.). This will bring temperature set of Ventilation= 27.0° at 41% of indoor humidity.

set, reducing the ventilation rate.
Increase of the temperature Ventilation set (see par. C.1) for every
1% of % RH decreasing the Minimum humidity value.
Make sure the Ventilation different. (par. D.1.3.1.F.3) is higher or
equal to this setting.
