6.15 Humidification
To adjust the comfort of the room it is necessary to also consider the humidity in the air and to regulate it based on a
determined Set point desired percentage (PU01) and at a neutral zone (PU02). If the room humidity sensor is present
it is possible to command the humidifier using On/Off switch or by using the module.
Humidity management is enabled by activating the parameter PG06>0, in the configuration menu. The room air
humidity sensor is also activated (PH41=1), if the sensor is disabled or in error dehumidification management will be
inhibited.
6.15.1 Enabling humidifier (flow temperature operation)
In order to function correctly the humidifier requires a minimum value for air temperature, for which it identifies a Set
point (PU11) and relative hysteresis (PU12) on the flow temperature to enable/disable the humidifier. This function is
enabled by parameter PU10. In case PU10=0 (function disabled) the humidifier will Start-up/shutdown on the normal
Set point percentage (PU01).
With the flow sensor in error the function is inhibited and the humidifier will Start-up/shutdown on the Set point
percentage.
6.15.2 Humidifier On/Off
In order to utilize the On/Off control of the humidifier you must set parameter PG06 to 1.
Note: in order to utilize this function it is necessary to enable the room humidity sensor, setting parameter PH41 to 1.
When the sensor is in error the humidifier is shut off.
