If you wish to adjust the displayed temperature up or down, there is calibration feature in your thermostat.  Although it is factory calibrated and should not need to be changed, you can adjust it to match a different thermometer in home.

To adjust your calibration, perform the following steps:

  1. Ensure that System mode is in “Off” and Set Slide switch in “RUN”.
  2. Press “Up” and “Down” buttons for 5 to 7 seconds.
  3. A number will pop up in the display between -5 and +5
  4. Use the up and down buttons to adjust it as desired
  5. Press “Next” to accept the setting.

*Maximum amount of time is 10 seconds between button pushes.

For example:  Putting this adjustment to – 2 will lower the display temperature by 2 degrees.  Putting this adjustment to + 2, will increase the displayed temperature by 2 degrees.

The maximum amount you can calibrate the thermostat is plus or minus 5 degrees Fahrenheit. (Plus or minus 2 Celsius)

Press “Next” to accept the setting.
