No 'cooling system' control needed, just fresh air w/o heat. Possible?
I want a regular programmable thermostat to turn the heat on/off, but I also want to be able to use the fan to circulate fresh air w/o heat occasionally. The fresh air would NOT be on a program, I would manually control it as needed. What description, what kind of thermostat should I be shopping for?
I have an ordinary natural gas furnace with ducted ceiling vents to each room. The heat is controlled with a wall thermostat. There is no cooling system.
Many thanks for any help you can provide.
