Question about Heating & Cooling
The closest number that I can find to that number is a battery t-stat, so I would guess that there is a battery in there.
Pull the t-stat apart and check it out....do you have a manual for that t-stat?... it will tell you...
If no battery then the fuse for the transformer or the transformer its self may have blown...
Check for 24v coming to the t-stat on the "R" wire....
