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


I prefer the standard single stage thermostat to go with a two
stage furnace. It is telling the furnace you need heat and the two
stage furnace then handles the transition between the stages just
fine, without the additional expense and complexity of a two stage
thermostat.
