Wiring new Thermostat to new furnace
Hello, I installed a new trane xr90 furnace and would like some help wiring the thermostat. I dont want to short out the board or anything. My furnace has the following connections. C, G, R, W, & Y. I am hooking that to a RTH7000 Honeywell programable thermostat. I will only be using Single stage heat for now but airconditiong in the future. I bought a five conducter themostat wire with G R W Y and Blue. There wasnt a blue on the furnace. Do I just need to hook up G, R W & Y to their prospective spots. Do I need the C terminal and what is it used for? Thanks for all your help.
