Humidity and Dehumidity
(setup steps 48 -54, 79-81)
Humidity Only With Heat (Setup Step 48) - When this step is set to ON, Humiditywill
not run without a demand for Heat.
Fan With Humidity Demand (Setup Step 49) - Specifies if the fan should be turned on
with a demand for Humidity. (This step will only appear if step 39 is set to OFF.)
Fan with Dehumidify (Set up Step 50) - Specifies if the fan should be turned on with
a demand for Dehumidify. (This step will only appear if step 42 is set to OFF.)
Humidity Setpoints (Setup Step 51) - Specifies whether the Humidity setpoint
should be entered by the user (MANUAL) or determined automatically by outdoor
temperature (AUTO). An outdoor temperature sensor is required for the AUTO
setting. If the outdoor temperature sensor stops reading while this step is set to
AUTO, the Humiditysetpoint will revert automatically to a setting of 15 percent.
Cool To Dehumidify (Setup Step 52) - Specifies if the cooling equipment is allowed
to turn on exclusively to lower room humidity. (If set to OFF the following two steps
will not appear.)
Max Dehum Overcool (Setup Step 53) - Specifies how many degrees below the
Cool setpoint the air conditioning will run to satisfy a Cool to Dehumidify demand.
(0˚ - 20˚)
Reheat Operation With Cool To Dehumidify (Setup Step 54) - Specifies if electric strip
heat is allowed to turn on during a Cool to Dehumidify demand to help maintain
desired room temperature. This step is not available if Electric Heat is not present.
Humidity Output Polarity
(setup step 79)
Open (Normally Open) means no voltage is sent to the HUM output when
there is no demand for humidity.
Closed (Normally Closed) means voltage is sent to the HUM output when there
is no demand for humidity.
Dehumidify Only With Cooling
(setup step 81)
When set to ON, Dehumidify will only turn on with a 1st stage cooling demand.
When set to OFF, Dehumidify will turn on at any time that the room humidity
exceeds the dehumidification setpoint.
Dehumidify Output Polarity
(setup step 80)
Open (Normally Open) means no voltage is sent to the DEHUM output when
there is no demand to dehumidify.
Closed (Normally Closed) means voltage is sent to the DEHUM output when
there is no demand to dehumidify.
