Hello:
A bit confused over the terminology on furnace thermostats. Embarassed to ask, but really want to be sure I have it right.
Does a 2 stage furnace (where there are two gas valve settings; a high heat and a lower heat output) require a 2 stage thermostat ?
I guess what's confusing me is the "2 stage thermostat" part.
By 2 stage on the stat, do they, perhaps, just mean a programmable setback temp., or is it really that you need this type to control (properly) a 2 stage furnace such as the Trane gas, forced hot air furnace I will be getting installed shortly.
Might anyone please explain this a bit.
Thanks, Bob
