I recently installed a programmable Rona Thermostat, its working great. There were only two wires to hook up so the furnace fan cannot be controlled from the thermostat. My furnace has a master switch that shuts down the heat and fan. There is also a small switch inside the furnace close to the furnace fan, which I now have on so that the furnace fan is running 24hrs. I would like to run wire(s) so that I can control my furnace fan from the thermostat. How can I do this? Note: the programmable Rona Thermostat instructions suggest only one more wire is required. Where would I attach, detach, or solder wires to allow me to run one wire for this purpose? Note 2: I dont have any electrical experience, but Im pretty good and figuring things out and not scared to learn. Thanks for anyone who can offer help, I can post pictures if that helps.
