How do I install a fan switch to my furnace
Hello,
I own a gas furnace that is 7years old its called coleman evcon.I would like to turn on my fan with out turning the heat on.
My furnace has 2 hires (white and black)caming to the thermostat. I understand I need a three wire relay out of the furnace to get my thermostat to turn the fan on with out heat, so how would I install a manual switch to turn
Fan on with out the heat.I don't want to fish the wire up my walls, I would like to install the switch right on my furnaces
I hope some one can help me out.
