Sometimes it would be nice to stir the warm air upstairs from the wood stove and the cool/cold air downstairs.
I've blocked the return air vents downstairs, turned the fan to "on" at the thermostat, and all I get is low speed which effectively does nothing.
I have seen thermostats that can periodically run the fan to do what I'm after, but I'm not sure I'd get any different behavior out of a different thermostat.
I've got a Lennox model G60-UHV(x) (not sure which one, I have that on some paperwork but I don't find that on the furnace itself).
I would like to be able to run the fan in high from the "on" position in the thermostat.
