Need help quickly. New thermostat.
I am set to make my 2018 maiden voyage tomorrow with the Mrs. Today I installed a Honeywell RTH111 digital thermostat in place of my Coleman Mach analog. I had the AC working, but heat didnt come on. I added the Blue wire to B. And nothing worked including the fan. I removed Blue altogether and now nothing works. No heat or AC.
I checked the fuses and reset the breakers and watched numerous youtube videos showing I am wired correctly. Green, Yellow, White and Red but still no heat or AC. The thermostat clicks but no heat or AC.
I am plugged into 120 at my house as I pack which normally supports the heat and ac.
I appreciate any assistance. We leave tomorrow, or not if I dont get this fixed.
