Question about Heating & Cooling
We had a power failure too but the faceplate seems to be dead and wondering if there is a battery in this obsolete model. thanks
No batteries in this one it uses a cap. to maintain the program. Did you remove the stat to chech for batteries? If so check the alignment of the six tiny pins on the sub base as they are very easy to bend when re installing the stat. If you did'nt.
Check for power at the furnace. If neither one is the case, I have replaced many of this stat with a Honeywell Focus Pro 6000 stat
