I am having trouble installing my trane thermostat. I have a standard Gas furnace and AC. I have 4 wires coming from the furnace, red, white, yellow, and green. When i connect these wires to the new trane unit, it does not even power on. However, if i put the yellow wire in the 24 COM slot, the unit will power on but not control the AC.
bypassing the thermostat and touching the red and yellow wires together, the AC kicks on and the furnace blower turns on as well.
I had the thermostat working all winter for the heat with the yellow wire in the COM slot, but with that setup the AC will not turn on.
Can anybody help me connect this?
