My husband has all of the instructions in every language except English. Somebody in the house messed with the thermostat and it appears that the temp is showing in Celsius instead of Farenheit. Can someone help

5 Press the up and down buttons simultaneously for 3 seconds until you see a number 1 and a small 0. To change from degrees C to degrees F press the up or down button to change the 1 to a 0. 0 = F. If you need to change any other function proceed to press the up , down buttons together to the next function(s) in the same manner.
