Humidity compensation configuration example |
The “Humidity Setpoint Compensation” sequence is designed to be used in combination with the Dehumidification function. During humidity control processes, the supply-air temperature may drop below the acceptable minimum limit even when the reheater is already operating at full capacity (100%). In such cases, the Humidity setpoint Compensation sequence helps restore the required temperature by counteracting the output of the humidity control function. The output (actual setpoint) of the humidity control function is proportionally reduced to increase the supply-air temperature.
The Humidity Setpoint Compensation sequence should be configured with a higher order number for Heating than the After Heater function.
