This unique accessory allows you to view and control
the humidity level using only your thermostat and
HVAC unit.
Depending on the model number of your thermostat
the humidification options are:
• View the ambient humidity at the thermostat
location
Control a humidifier with the HUM terminal on
the thermostat
Dehumidify using only the air conditioner
Dehumidify with Reheat using your HVAC's
second stage electric strip heater
Dehumidify using the DEHUM terminal on your
furnace's circuit board

The humidity accessory is inserted into the
humidity plug on the back of the thermostat
and the Humidity Jumper is set for HUM
operation.

To control a MISC output for humidification, place
the MISC1, MISC2, or MISC3 jumper on the term-
inal labeled HUM. This will supply 24VAC to the
selected MISC terminal on the backplate of the
thermostat when the humidity in the home falls
below the setpoint you have chosen. The value for
this setpoint ranges from 0% to 60%. Only one of
the three outputs (MISC1, MISC2, or MISC3) is
required to have this jumper. For more information
regarding the MlSCl, MISC2, and MlSC3 outputs
and regarding the Humidity setpoint, please consult
your Owner's Manual.
The Fan may also be programmed to automatically
energize any time there is a call for humidity. For
more information regarding energizing the Fan with
Humidification operation, please consult your
thermostat's Owner's Manual.

Dehum Terminah To control a MISC output for
dehumidification, place the MISCl, MISC2, or
MISC3 jumper on the terminal labeled DEHUM.
This will supply 24VAC to the selected MISC
terminal when the humidity in the home is above the
setpoint you have chosen. Only one of the three
outputs (MISCl, MISC2, or MISC3) is req-
uired to have a jumper. For more information
regarding the MlSCl, MlSC2, and MlSC3 outputs,
please consult your thermostat Owner's Manual.
When the indoor humidity falls below the setpoint
you have selected, the MISC terminal will be de-
energized. The value for this setpoint ranges from
25% to 99%. To utilize this feature your HVAC unit
must be equipped with a DEHUM terminal. For
more information regarding dehumidification using
the DEHUM terminal, please consult your
thermostat's Owner's Manual.
*Dehumidifying with the DEHUM terminal may not be available
with your thermostat model number. Please consult your
Owner's Manual for details.

Cool to Dehumidify: If Cool to Dehumidify is on
and the Humidity Module is installed, the thermo-
stat has the ability to initiate a cooling cycle for
advanced dehumidification operation. When the
thermostat detects the humidity percentage is
above the setpoint for dehumidification, and heating
or cooling is not on, the thermostat will force the
compressor to run with the fan, thus reducing
moisture in the air. The green LED will blink once
every eight seconds to indicate this is taking place.
This feature will also allow you to adjust the cooling
overshoot of the setpoint, from 0 ° to 5 °.
For Example: If the coofing overshoot is set for 3 °F and
the cooling setpoint is set for 74°F, then as long as the
room temperature reads between 71°F and 74°F this
feature will energize the compressor and fan to
dehumidify the air.
When the indoor humidity falls below the setpoint
you have selected, the Cool to Dehumidify function
will be de=energized. The value for this setpoint
ranges from 25% to 99%. For more information
regarding dehumidification using the air conditioner,
please consult your Owner's Manual.
*Cool to Dehumidify may not be available with your thermostat
model number. Please consult your Owner's Manual for details.

Reheat: This feature allows the thermostat to turn
on Electric Heating (W2) during Cool to Dehumidify
(see previous page) to maintain room temperature
until the dehumidification setpoint is reached. The
cooling cycle will allow for the dehumidification of
the air to occur while the Electric Heating will allow
for a constant room temperature. If Reheat is
enabled, the Aux icon will appear on the display
during Cool to Dehumidify operation. For more
information regarding Reheat operation, please
consult yourthermostat's Owner's Manual.
*Reheat with Cool to Dehumidify may not be available with your
thermostat model number. Please consult your Owner's Manual
for details.
