We have Carrier Parker VVT controls in our building, not sure if they're Gen I or II, maybe someone could tell me how to find that out.
Anyways, they're about 20 years old, and only one of the "main" control panels is having issues. The time on it won't stay, it looses time every day or two, causing it to go into setback in the middle of the day.
None of the others in the building do this, is there some kind of battery in this system, or is my 24V transformer for this one thermostat going bad?
Any help would be greatly appreciated, thank you so much, great forum, btw!
