Relative humidity control
The
Relative humidity control
folder includes the following secondary folders:
Dehumidification
Humidification
Calculated psychrometric values
The secondary folders
Dehumidification, Humidification
and
Calculated psychrometric values
appear
only if a humidity sensor is enabled, either internal or external (from bus). If an external humidity sensor is
enabled, the acquisition of relative humidity is made by bus from a KNX R.H. sensor.
The sensor acquires the air humidity value inside the room, which can be used for the following purposes:
Sending over the bus (for information purpose) through DPT [9.007] percentage (%);
Use of detected value for dew-point temperature calculations and sending on the bus through
corresponding DPTs;
Use for room ventilation through ventilation start, external intakes opening, window opening through
motorized actuators. Control is performed upon thresholds;
Use for control of thermoigrometric comfort conditions of radiant panel cooling systems equipped with
integration of latent heat (starting of dedicated terminals without modification of cooling water flow
temperature);
Use for safety control in radiant panel cooling systems not equipped with integration of latent heat
through calculation of critical thermoigrometric conditions (dew point) and corresponding modification
of cooling water flow temperature.
