My problem is that I have two thermostats for the furnace I don't have AC. One has the power switch for the furnace fan and the other is just a normal thermostat but for the life of me I can't figure out how to use them. Can someone give me a run down on how to use two thermostats for the one furnance. Is one for when txt kick on the fan to blow hot air and the other is the temp setting for the heat. I'm just Unsure I have never ran into this problem before. Thank you for your help and happy RV'ing
