: 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?
Either you are miss pre and post purge controls on the power vent. Or it is wired wrong. Or the puge relay in defective
