So, after alot of reading and troubleshooting we have determined that the Taco pump only runs when the blower /burners are on. It is my impression that is is supposed to run off the inital call for heat, then the water temp determines the blower/burner coming on. So, is this a bad aquastat? What is happening is that the water does not circulate enough 2-5 minutes and the system shuts down because its hot. Can I just rewire so the pump will operate all the time?
