NOTE 1: The thermostat must be in any mode other than
OFF (section 2) to adjust temperature setpoint(s).
NOTE 2: The thermostat forces a 2°F “dead-band” between
the Heating and Cooling setpoints. While adjusting
the Heating setpoint, the Cooling setpoint may be
automatically increased to enforce a 2°F “deadband”. Likewise, while adjusting the Cooling
setpoint, the Heating setpoint may be automatically
reduced to enforce a 2°F “dead-band”.
NOTE 3: In programmable mode, the TEMP option provides
the ability to temporarily modify setpoint(s) until
the start time of the next program schedule event.
While in non-programmable mode, the TEMP
option provides the ability to modify the setpoint(s).

4.0 Humidity Level Adjustment
NOTE 1: The thermostat must be configured by installer for
humidity control to access the humidity setpoint(s).
To adjust the Relative Humidity level on your thermostat,
use the left/right arrow buttons to select the RH user
option on the Home Screen and then press the center
button. The Humidity Control screen shows either one (with
Humidification or Dehumidification enabled alone) or both
(with BOTH enabled) humidity setpoints. Adjust the setpoints
using the up/down arrow buttons. Press the center button to
save changes.
• Humidification Setpoint (default 40%): options:
10% to 45% (in 5% increments)
NOTE:
Humidifier must be installed to set humidification
setpoint.
• Dehumidification Setpoint (default 60%):
options: 45% to 80% (in 5% increments)
NOTE 2: The thermostat forces a 10% “dead-band” between
the Humidification and Dehumidification setpoints.
While adjusting the Dehumidification setpoint,
the Humidification setpoint may be automatically
reduced to enforce a 10% “dead-band”. However,
the Dehumidification setpoint will not be
automatically increased to enforce a 10% “deadband” while adjusting the Humidification setpoint.
The maximum range for the Humidification setpoint
may be limited by the Dehumidification setpoint.
NOTE 3: If an outdoor sensor is present, the Humidification
setpoint will be calculated automatically for optimal
comfort.

Smart recovery is a feature designed to save
energy by gradually adjusting temperatures. When
it is time for a program schedule temperature
change, smart recovery begins working in
advance, turning the system on and off as needed
to slowly adjust the indoor temperature so that
it reaches the program temperature setpoints at
the time you set. Rather than waiting to start the
equipment until the program time has occurred.
Adjust the Smart Recovery setting using the up/
down arrow buttons. Press the center button to
save changes.

you find that the thermostat is operating auxiliary
heating equipment too quickly/slowly, this setting
allows for adjustment to correct the temperature
algorithm.
Adjust the Smart Heat Staging setting using the up/
down arrow buttons. Press the center button to
save changes.
• Smart Heat Staging (default Off): options:
OFF, 5 – 120 minutes (in 5 minute increments)
5.6.5.4 ELECTRIC HEAT LOCKOUT

programmable mode by installer to access the
Smart Recovery setting.
5.6.5.5 PROGRAMMED DEMAND REDUCTION
Programmed Demand Reduction is a feature
designed to reduce your electric load during
preselected time periods in which peak utility rates
are high. You can program your thermostat to
reduce the electric load by limiting operation or
capacity during the high utility rate time period that
you specify for each day of the week.
NOTE 2: Auxiliary heat will not be used during
Smart Recovery.
While the Programmed Demand Reduction mode
is active, the thermostat outputs will be limited

be activated, regardless of the heating
demand.
• No 2nd Stage Compressor: During the
scheduled Programmed Demand Reduction
time (section 5.6.5.5.4), the compressor
is limited to only part load (1st stage)
operation and auxiliary heat is turned off,
regardless of system demand.
NOTE 1: The thermostat must be configured for
auxiliary heat by installer to access the Demand
Reduction NO AUXILIARY HEAT option.
NOTE 2: The thermostat must be configured
for Multistage by installer to access the Demand

5.6.6 INTERMITTENT FAN
Intermittent Fan function allows the fan to run
periodically when the heating/cooling equipment is
off. Many times this functionality is used to improve
the performance of air cleaning or special filtration
systems.
When the Intermittent Fan function is active, the fan
output will be activated for the currently selected
Intermittent Fan On Time, and then operate using
the selected Intermittent Fan Off and On times until a
heating or cooling operation is activated again.
After the heating or cooling operation is complete,
the intermittent fan operation will resume with the
beginning of a new Intermittent Fan On Time on the ¼
hour.
• On Time (default Off): options: Off, 5 to 20
minutes (in 5 minute increments)

load while peak utility rates are high. While the
Demand Reduction mode is active, the thermostat
will implement load reduction by limiting operation or
capacity. The thermostat outputs will be limited by
the Demand Reduction option selected below (section
5.6.9.1).
NOTE: The thermostat must be configured for
Demand Reduction by installer to access Demand
Reduction settings.
5.6.9.1 DEMAND REDUCTION MODE
Through Demand Reduction Mode, you can set the
unit’s limited operation while Demand Reduction is
active.
Adjust the Demand Reduction Mode settings using
the up/down arrow buttons. Press the center
button to save changes.
• No Auxiliary Heat (default): While the
assigned Demand Reduction input is active,
auxiliary heat will not be activated regardless of
the heating demand.
• No 2nd Stage Compressor: While the
assigned Demand Reduction input is active,
the compressor is limited to only part load (1st
stage) operation and auxiliary heat is turned off
regardless of system demand.
• No Operation (default – if either setting is
not present): While the assigned Demand
Reduction input is active, the thermostat
outputs will not be activated for heating or
cooling regardless of the heating or cooling
demand.
NOTE 1: The thermostat must be configured for
auxiliary heat by installer to access the Demand
Reduction NO AUXILIARY HEAT option.
NOTE 2: The thermostat must be configured
for Multistage by installer to access the Demand
Reduction NO 2nd STAGE COMP option.

NIGHT SETBACK
Under Night Setback mode, the thermostat will operate using
alternate Night Setback heating and cooling setpoints, fan
mode, and humidification and dehumidification setpoints.
Night Setback is activated by an input signal at the unit
control board to reduce the electric load while the building is
unoccupied.
NOTE: While the Night Setback mode is active, the screen
backlight will be red when ON.
5.8.1 NIGHT SETBACK SETPOINTS
Adjust the Night Setback setpoints using the up/down
arrow buttons. Navigate between Night Setback
setpoints using the left/right arrow buttons. Press the
center button to save changes.
• Heat Setpoint (default 60°F): options: 55°F to
Maximum Heating Setpoint Limit (section 5.6.8)
• Cool Setpoint (default 80°F): options: Minimum
Cooling Setpoint Limit (section 5.6.8) to 95°F
NOTE: The thermostat forces a 2°F “dead-band”
between the Night Setback Heating and Cooling
setpoints. While adjusting the Night Setback Heating
setpoint, the Night Setback Cooling setpoint may be
automatically increased to enforce a 2°F “dead-band”.
Likewise, while adjusting the Night Setback Cooling
setpoint, the Night Setback Heating setpoint may be
automatically reduced to enforce a 2°F “dead-band”.
5.8.2 NIGHT SETBACK OVERRIDE
While the Night Setback mode is active, the
alternate Night Setback setpoints can be temporarily
overridden, by using the normal temperature
adjustment screen. If the heating and cooling
setpoints are adjusted while Night Setback is active,
these temporary setpoints will remain active for the
current Night Setback Override time, unless they are
adjusted again, or the Night Setback mode is deactivated.
Adjust the Night Setback Override setting using the
up/down arrow buttons. Press the center button to
save changes.
