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 on 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.
TEMPERATURE LIMIT STOPS: There are two independent set temperature
limit stops: a maximum heat set temperature, and a minimum cool set
temperature. These stops do not prevent a user from performing normal
actions like Temperature Override or Hold. The Heat Limit Stop prevents
the set temperature from being adjusted higher than the heat limit setting.
The Cool Limit Stop prevents the set temperature from being adjusted
lower than the cool limit setting. Each of these temperature stops is user
adjustable in one-degree increments, and these settings are protected by
a selectable 2-digit code to prevent unauthorized tampering. By default,
this 2-digit code is “00”, and the temperature stops can be used as-is with
this code.
NOTE: The Temperature Limit Stop settings need to be performed in a
timely manner, as the thermostat will timeout and automatically exit the
setting screens after approximately 10 seconds without a button press.
