Notes
Select a sensor to control dehumidification
(thermostat or an optional remote sensor). If
multiple sensors are installed, you can use a
different sensor for humidification control. See
"Dehumidification control" beginning on
page 113.
Note: Humidity sensing cannot be averaged.
This ISU is only displayed when separate humidity
sensors are used to control humidification and
dehumidification. Only one of the sensors can be
displayed on the home screen. Select either the
Humidification Sensor or the Dehumidification
Sensor.
Number of Outputs:
TH8321 Thermostat: U1 terminals
Equipment Interface Module (EIM): U1, U2 and
U3 terminals
U1, U2, U3 are dry contacts that require power.
See "Wiring IAQ Equipment or a Heat/Cool Stage
to the U Terminals" beginning on page 130.
Choose an option appropriate for the type of
equipment installed.
Normally Open: U1, U2 or U3 will normally be
open and will close when the thermostat calls for
dehumidification.
Normally Closed: U1, U2 or U3 will normally be
closed and will open when the thermostat calls for
dehumidification.
Number of Outputs:
TH8321 Thermostat: U1 terminals
Equipment Interface Module (EIM): U1, U2 and
U3 terminals
This ISU is only displayed when ISU 900 Dehum
Equipment is set to A/C with Low Fan or A/C with
High Fan.
The thermostat uses the cooling system to reduce
humidity by lowering the temperature up to 3° F
below the current cool setpoint until the desired
humidity level is reached.
The thermostat keeps the temperature below the
cooling setpoint until the desired humidity level is
reached.
0° F is only an option when ISU 900 Dehum
Equipment is set to A/C with Low Fan.
