How do I switch between Fahrenheit and Celsius on my thermostat?

The temperature scale of your thermostat can be converted between Fahrenheit and Celsius

If you wish to change the temperature displayed to read Celsius instead of Fahrenheit, (or Fahrenheit to Celsius):

1. 1. Take the front cover off the stat off the wall.
   2. Look on the circuit board to find the dip switch table which tells you what the dip switches are for.
   3. Look for the Row that has C in one block and F in the other.  Look to the left and note the dip switch number (for example “2”).  Now look on the circuit board for a blue block with small white switches.  Use a pen or pencil to move this white switch to the opposite position.
   4. Now press the small white button on the circuit board labeled “Hardware Reset”
   5. You will see 88:88 flashing in the display.  Rotate the dial to “Set Day/Time and fix the day and time.  Rotate the dial back to “Run”.  Temperatures will now display in the other scale.
   6. Finally, put the front half of the thermostat back onto the wall.

   All other programmed values will be “remembered” by the thermostat.
