Question about Honeywell Programmable Thermostat Heater
I have a Honeywell RTH7400D programmable thermostat installed and working fine, except that I cannot change the display settings from farenheit to celsius. The package stated that it was both farenheit and celsius capable but the manual does not tell you how to switch it. I live in Canada - everything is in celsius except my thermostat.
A solution would be greatly appreciated.
My thermostat was set on celsius and couldn't get it to change back to fahrenheit. My son suggested pressing both up and down arrow buttons at the same time and it worked. It changed back to fahrenheit.
