Humidity Deadband
A deadband widens the setpoint to prevent small changes in humidity from activating humidifiers, compressors and valves
and cause excessive component cycling.
Figure 3.12 below , illustrates humidity control using:
• 50% setpoint
• 8% proportional band
• 2% deadband
Like the proportional band, the deadband is also divided evenly on each side of the setpoint.
• 0% cooling capacity is required from 49% to 51%.
• Below 49%, humidification operates according to the humidity proportional band.
• Above 51%, dehumidification operates according to the humidity proportional band.
