For units controlled by space humidity sensors, Dehumidi
fi
cation
is initiated based on an Indoor Humidity Setpoint. For 100% OA
units (MUA), Occupied Dehumidi
fi
cation is initiated based on
an Outdoor Air Dewpoint Setpoint. For MUA units, Unoccupied
Dehumidi
fi
cation can only occur if the unit is con
fi
gured for Night
Setback recirculating operation and has a Space Humidity sensor
and a Space Humidity Setpoint.

For the controller to properly calculate the Outdoor Air CFM, you
need to
enter
the area in square feet of the Outdoor Air duct/damper.
When measuring the Outdoor Air duct damper area, be sure to mea-
sure the inside dimensions of the damper. The duct size needs to be
accurate to two decimal places. The more accurate the measurements,
the more accurate the CFM reading will be.
Default is 0.
