yes, it will work.... when you say the thermostat failed, how did it fail, screen go bad or blank or did heat or air stop working? How is the humidifier wired?
Honeywell TH8320U and Amana LP Furnace/AC
3 of these thermostats have failed in the last year. 2 were installed by the contractor who installed the system and 1 by a second installer. Both companies are well respected and have been in the business for decades. I emailed Honeywell and they wouldn't discuss my problem.
In any event, I don't think I'm going to attempt to fix my problem but am looking for possible problems that may have been overlooked. I also have a Aprilaire humidifier.
The labels on the board in the furnace are:
O
YLO
Y
B/C
G
R
W
W2
DEHUM
on the back of the thermostat (Conventional Columns) are:
Left side:
Y2
W2
S1
S2
Right side:
RC
R
W
Y
G
C
Can anyone shed some light on this or perhaps let me know if this thermostat is incompatible? When it worked, it seemed to work fine. Thanks

thermostat = furnace
Rc and R = R
W2 = W2
W = W
Y = Y
G = G
C = B/C
These are the standard connections that should be hooked up.......without knowing if you have a heat pump or 2 stage a/c I cant tell you what else should be hooked up. The humidifier should really have its own transformer. Do you have a lot of power outages or spikes?
Screen was blank..........did you check the batteries in stat if applicable? Stat may not be receiving 24V from furnace.

there may be an excessive amp draw though one of the components........the tech should check for that due to excessive amount of failure
