Relative Humidity Compensation: How it Works
The controller offers different ways to compensate for high/low relative humidity (RH) levels in the room.
High RH compensation with the heating outputs
The controller can compensate for high humidity levels by activating the heaters in timer mode. As the
RH level increases, the controller increases the “On Time” portion of the heating timer to compensate for
the change. The maximum compensated heating Max “On Time” is reached when the RH level is 10%
above the RH Set Point.
RH heat timer
The RH heat timer is composed of an “On Time” and of a “Cycle Time”. The heaters run during the “On
Time” and then stop until the end of the “Cycle Time”. The “On Time” portion of this cycle increases as the
RH level increases.
