My main living room has a 25 foot cathedral ceiling with a ceiling fan including a staircase going to the second story bedrooms. The thermostat is situated in this space.
There is space to install a vent and ducts to move air from this ceiling hot zone to the first floor main bedroom. I would like to create a system that has:
- Has two temperature probes - one in a the "hot" area and the other in the "cold" area.
- Controller which will detect if there is a "Max" difference between the hot and cold zone,
- Start the fan in the new duct which will stop when the second "Min" temperature difference between the hot and cold zone is reached.
Is there something like this commercially available or do I have to cobble it together myself with a 1-wire system or multiple thermostats?
