Unneeded Taco Zone valve

Do I need power hooked up to a Taco Zone valve to have it manually open?
Basically I have a zone valve on our system of our extremely small house. It isn't necessary. Plumber fixed something on boiler over summer and disconnected the wiring and said to just leave it in the open position.
Heat isn't circulating this year and I can hear the circulator running.
So I am wondering if there is a way to determine if that valve isn't staying in the open.

No you dont need power to have it manually open, but if you have one zone valve it means there is another. The other one will need power to operate the end switch to fire the boiler.

These are often wired together and possibly the plumber disconnected something he should'nt have on the other zone.

Heat isn't circulating this year
To just that zone??? Do you get heat to the other zone?

Check the lever of the zone valve.
