Setting or changing heating/cooling setpoints
Your thermostat is installed with pre-set heating and cooling temperature
setpoints. You can use these or change them so your home is as warm or as
cool as you would like it to be. You can also temporarily change the tempera-
ture after you've programmed your thermostat according to your specific
schedule needs.
Follow the steps below to temporarily hold the temperature where you set it for
two hours until the next programmed cycle begins.
1. Open the thermostat door. You will see an arrow next to the word off, heat
or cool in the upper right corner on the screen, depending on the mode your
system is in. (If it's the first time you've used the thermostat, it will say
heat.) The pre-programmed heating or cooling temperature is displayed in a
box at the bottom of the screen.
2. To change the displayed temperature, press the up or down button located
on the right side of the display until you reach the desired setting.
3. To change the other temperature setpoint, press the mode button above
the screen. The arrow will move to the word cool or heat and the screen
will show that temperature in a box in the lower right corner

4. Press the up or down button, located to the right of the display, to change
the displayed setpoint. Stop on the desired setting.
5. When there are arrow indicators next to both the wordsheat and cool at
the top right of the screen, the heating and cooling temperatures are also
displayed at the bottom of the screen. You can change either one by
pressing the soft button below the setpoint temperature you want to
change, then pressing the up or down button to adjust the temperature.
Repeat the process for the other setpoint if necessary. Press the done
button when you are finished.
6. The thermostat will hold these changes for two hours or until the next
programmed cycle begins. The words hold for 2:00 will be displayed while
this temporary hold is in effect. To change the amount of time the tempera-
ture is on hold, press the soft button under the hold hours or
minutes. Then press the up or down button to adjust the hold time.
