New system, Smith Cast Iron, Beckett Burner, taco control system, Honeywell Aquastat, etc. 4 zones.
No chimney, so a power vent was employed.
Any time any zone calls for heat, the power vent runs. This is even if the boiler does not need to run, just the circulator. I am worried because the power vent seems to run almost continuously, and if the boiler is not running, it is just pulling warm air from the basement.
Any ideas? A different aquastat? A different controller on the Beckett? A different Taco? Or is this how it's supposed to be?
