TEMPERATURE CALIBRATION: The internal temperature sensor in this
thermostat is accurately calibrated at the factory, and in most cases
alterations to this setting should not be needed. The Temperature
Calibration feature allows you to manually offset the measured temperature
by as much as plus or minus 5°F (3°C) degrees from its original value. This
feature can be useful to match or synchronize this thermostat to another one
or more, if multiple thermostats are used in the same home.
NOTE: The Temperature Calibration setting need to be performed in a timely
manner, as the thermostat will timeout and automatically exit the adjustment
screen after approximately 10 seconds without a button press.
TO CHANGE THE TEMPERATURE CALIBRATION: Ensure that the System Mode
switch is in the OFF position and the Set Slide switch is in the RUN position.
Press and hold both the UP and DOWN buttons together for at least 5
seconds. The words “SET” and “CAL” will appear in the upper right corner
of the screen, along with a single flashing temperature digit. Use the
UP/DOWN buttons to change the number of degrees of adjustment. 0°
degrees is the default value, and means no correction is being applied.
Press the NEXT button to accept the setting.
SETBACK FEATURE: The setback feature is similar to both a Temperature
Override and a Temperature Hold, in that both are used to maintain a fixed
set temperature instead of following a programmed daily routine. A Setback
can be considered the same as a Temperature Override, which can last for a
longer duration that you can adjust from 1-12 hours, or 1-30 days. By
default, when a Setback is activated in Heat mode, the set temperature used
will be 5F (3C) degrees lower than the current set temp. For Cool mode, the
set temperature used will be 5F (3C) degrees higher than the current set
temp.
TO START A SETBACK: Ensure that the System Mode switch is in either the
Heat or Cool position, and that the Set Slider is in the RUN position. Press
and hold the SETBACK button for at least 2 seconds. The screen will change
and show the words “HOURS LEFT” and “OVERRIDE”, along with two digits.
Use the UP/DOWN buttons to set the duration for how long you would like to
maintain a fixed set temperature (from 1 to 12 hours). If you would like to
set the duration for longer than 12 hours, keep pressing the UP button. The
display will change from “HOURS LEFT” to “DAYS LEFT”, with an available
duration of 1 to 30 days. Once your desired Setback duration is shown on
