  • Normal Dehumid: The sequencer is in this state if the cooling and heating output controllers are responding to this sequencer and the Dehum Process Variable is greater than the Humidity Setpoint.

  • Humidity Unreliable: This is the unreliable state. The sequencer is in this state if the Process Variable sensor becomes unreliable.

  • No Dehumid: The sequencer is in this state if the Dehum Process Variable sensor is reliable and any of the three following conditions are true:

    • The heating device is not responding to this sequencer.
    • The cooling device is not responding to this sequencer.
    • The Dehum Process Variable is less than the Humidity Setpoint and the heating output controller Control Status is Low.
