Next door neighbor has a 2-zone HW heating system. (baseboard) It has two pumps each controlled by a thermostat. (one for each pump) The burner is controlled by an aquastat. A second neighbor contends that the pumps could run continuously and the stats would still control the heat. (the stat wires go to a relay that closes when the stat calls for heat and activates the pump) I contend there is no way to control the heat if you bypass the relay and make a direct connection to the pump. (for continuous operation) Am I missing something here?
