I'm in the process of upgrading from a 40-year old single-stage gas
furnace
to a 2-stage model (80% efficiency).
I currently use a Hunter brand programmable thermostat on the existing
furnace.
One of the contractors placing a bid for the new 2-stage Amer Stnd/Trane
tells me that I'll need to replace the thermostat with one that is
compatible with a 2-stage system. Is he right, or simply blowing smoke up
my
butt?
TIA


To get full advantage of your two stage furnace, buy a two stage 'stat. Some
two stage furnaces will run with a single stage 'stat, but it will run more
efficiently with a proper two stage 'stat.

Hi,

No, he is right. A two stage unit needs a different t stat to work with the
Trane logic board correctly.

Besides the contractor being correct, the Hunter unit is ready
to be replaced with a more sophisticated unit anyway.

Why not to replace? A thermostat is cheap, $20 can get you one. The
saving would recover the cost in month.

Hi Karen, hope you are having a nice day

Damn! A $20, two stage 'stat! I can not believe I have been paying $100 or
more!
