OFFSET: After the swing value has been accepted, the words “SET:” and “OFFSET” will be shown on the screen. This setting is shown as a number of degrees, and is similar in nature to the swing however it only effects the operation of the second (auxiliary) heating stage, if present. The setting range for Offset is from 0 to 9 degrees. When set to 0 degrees, the second heating stage is disabled. A value from 1 to 9 degrees will determine the number of degrees from the set point that will be required for the second heating stage to turn on. This setting can be used to conserve energy in cases where the second heating stage is costly to operate when compared to the first stage.
USER TEMPERATURE CALIBRATION
The internal temperature sensor in this thermostat is accurately calibrated at the factory and should not need to be adjusted. 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 this thermostat to another one or more, if multiple thermostats are used in the same home. To change the Temperature Calibration: ensure that the System Mode switch is in the OFF position, and the rotary dial is in RUN. Press the COPY/EMER button for at least 2 seconds. The words “SET:” and “CAL” will appear on the screen with a single temperature digit shown. Use the UP/DOWN buttons to change the number of degrees of adjustment. 0° degrees is the default value. Press the NEXT button to accept the setting.
