Hello, I have a honeywell th8320 thermostat that is causing me to scratch my head. When i orginaly got this I installed it and its worked great since. well as I was re-reading the manual out of curiosity I found a setting in the installer options manual that allows for my back light to stay on dim with the 24v c connection. Problem is The manual says I need it connected to the 24vac C wire and from what I gather the c wire gets its power from the AC contactor 24v. Well I dont have AC so there is no power to my C wire for my backlight.
Can I just jump it to the constant 24v R wire to get it to stay lit?
I cant see it being a problem but i figured I would ask.
