2.0 Temperature Adjustment

To adjust the temperature on the thermostat, use the left/
right arrow buttons to select the

TEMP

user option on the

Home Screen and then press the center button or press the
up or down arrow key. The Temperature Adjustment Display
appears and shows either one (in Heat, Cool, or Emergency
Heat modes) or both (in Auto mode) temperature setpoints.
Adjust the setpoints using the up/down arrow buttons.
Navigate between 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 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 “dead-
band”. 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).

NOTE 4

: When the up/down arrow buttons are engaged, the

last mode of operation is highlighted.

3.0 Fan Mode Selection

To adjust the Fan Mode on your thermostat, use the left/
right arrow buttons to select the

4.0 Humidity Level Adjustment

NOTE 1

: The thermostat must be confi gured 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

user

option on the Home Screen and then press the center
button. The Humidity Control screen shows either one (with
Humidifi cation or Dehumidifi cation 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.
•

Humidifi cation Setpoint

(default 40%): options:

10% to 45% (in 5% increments)

NOTE

: Humidifi er must be installed to set humidifi cation

setpoint.

•

Dehumidifi cation Setpoint

(default 60%):

options: 45% to 80% (in 5% increments)

NOTE 2

: The thermostat forces a 10% “dead-band” between

the Humidifi cation and Dehumidifi cation setpoints.
While adjusting the Dehumidifi cation setpoint,
the Humidifi cation setpoint may be automatically
reduced to enforce a 10% “dead-band”. However,
the Dehumidifi cation setpoint will not be
automatically increased to enforce a 10% “dead-
band” while adjusting the Humidifi cation setpoint.
The maximum range for the Humidifi cation setpoint
may be limited by the Dehumidifi cation setpoint.

NOTE 3

: If an outdoor sensor is present, the Humidifi cation

setpoint will be calculated automatically for optimal
comfort.
