I have a gas furnace "Trane 80", which was operated by an old round thermostat, and a two conductor thermostat wire.There was no switch to turn on "summer Fan" manually. I replaced the old thermostat with a "Garrison" programmable thermostat. If I want to have manual fan control, and wire for future Air Conditioning, how many conductors will I need to pull?
