Glad it works! My wiring looked like that when I did my wireless T-stat on my vintage furnace. I couldn't sleep until I straigtened it out with some tidy wire management!
I accidentally forgot about the original thermostat when we remodeled the kitchen and buried the wires behind sheet rock :redface:
So wireless was the only option. I have the T-stat stuck on the side of the fridge with magnets. I have a single zone system, so bonus with the wireless is I just bring the thermostat into the room I'm in during the winter and I'm always at a comfortable temp :rotflmao:
