How do you switch my new thermostat to celcius

This should be very easy to do.Normally, there is a switch to do this located behind the front cover. Just grasp it and pull it off to see if it is located there. Sometimes, you will have to go into the program and do this change. If you have the manual, this will help. Honeywell stats are top of the line. If you cant figure it out, make a call to a air conditioning wholesale parts house with the model # and they can also tell you.I am sure you will find the switch behind front cover. Sincerely,
