I had the older model of this comfort ZC, when I plugged in the new it automatically went to Celsius. I have tried several things to include reading the instructions.....I do not understand in the instructions where and or what a jumper is and then it also says I should do something in the unit. Please help as I am very new to the electronics of this system....Thank you
In turning on zone 2, zone 1 will not turn on move from modes to even turn on...Zone 2 works just fine. its in the thermostat.

Move the Fahrenheit/Celsius jumper to the desired setting. The jumper is preset at the factory to Fahrenheit. To change simply pull the jumper and connect it between the center post and either the left post for Fahrenheit or the right post for Celsius Take the cover of the tstat off and look on the c board.
