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. Turn the dial to “Set Day & Time”
  2. Press Next & Hold at the same time
  3. A number will pop up in the display between -5 and +5 (0 is the default)
  4. Use the up and down buttons to adjust it as desired
  5. When you are finished, rotate the dial back to “Run”

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)
