Hello! My 29.5 BHDS has two 15 btu A/Cs with the manual slider thermostats. I went out and bought two Coleman Digital Wall Thermostats (8330-3862) to replace them (as most have said they are wire for wire replacements)
I upgraded the first A/C and everything appears to work normally. I was wiring in the second when I realized the thermostat had one more wire than what was coming from the wall. After closer inspection and hours of hard detective work, I realized the second A/C thermostat doesn't have a "heat" .. duh.
Looking at the documentation, the lone white wire is what triggers the furnace.
My question - if I just wire nut that wire off, would I be doing anything "risky"? Seems like thermostats aren't very complicated and it wouldn't present any risks to not hook up that wire..?
Would it be better if I attached the furnace wire to the compressor wire? So heat or cool would always start the AC?
Orrrr should I just buy the right thermostat?
Thanks for the opinions!
