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.
TO SET THE HEAT LIMIT STOP: Place the System Mode switch in the OFF position,
and the Set Slide switch in the RUN position. Press and hold the UP button while
sliding the System Mode switch from OFF to HEAT. The words “STOP” and “LOCK
CODE” will appear on the screen, along with two digits. Use the UP/DOWN
buttons to select the proper code to access the heat limit setting. Press the
