Hello,
I'm a new home owner and came across my first project. I have an AC system (doesn't seen to work), and a gas furnace for the heater. I purchased a basic digital Honeywell thermostat to replace my mercury one. The wiring doesn't seem to make much sense to me, as I figure I just match the colors accordingly?
One image is the wiring on the mercury thermostat. 1-red, 1-yellow, 1-white, 1-brown? But the part that confuses me is how the yellow wire hooks up to the white terminal. How do I wire for the digital thermostat?
Thanks
