may continue to perform short single presses of the COPY/EMER button to
proceed with copying to the remaining days, one after the other (specific days
may be skipped by pressing the UP button to advance past them when they are
flashing in the “copy to” location). To exit the Copy feature, and return to the
regular temperature program screen, press and hold the NEXT button for more
than 2 seconds. Return the Set Slide Switch to the RUN position when you are
finished.
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.
