when another zone other besides the main floor comes on.

When the other zones stop calling for heat, the water temp goes all
the way down below 100 f

No, it was fine for awhile

> Have you checked your wiring connections?
No--the wiring is complicated to me. But when the main floor
thermostat calls for heat, the pump definitely turns on. I will have
to figure out how the signal gets sent to fire the boiler.

Service life, and i did witness a similar occurrence of that zone
getting heat after another floor called for it. I decided to replace
the pump when i figured out that that pump's motor was getting
extremely hot. I did not check the water temp in the boiler. I can see
where you are going with this. The water in the boiler is cold, so
it's not like the pump is being called to shut off so it probably is
not a pump problem.

I guess i should dig into the wiring?
