Zone and boiler run for seconds
So I was in the basement redoing some wiring...and I hear a zone valve open (I am working almost on top of the boiler). It's the basement zone calling for heat, the valve opens, and closes maybe ten seconds later. My Taco controller box has the light for the thermostat call out after the run as well. No way in ten seconds was there any change in area temperature....
Then maybe an hour later, the boiler fires on. Runs for about ten seconds, then shuts off. Wasn't near enough to the Taco box to see what was going on.
Is this normal behavior? If not, what gives do you think? Just me in the house, so no DHW being used either.
Pardon any typos, my IPad has a mind of it's own for spelling corrections!
