shut down and resume once the call for DHW has ended



BOILER – dry contacts to initiate heat source



AUX 24V – 24VAC output for humidifier or other accessory. Active when heating is on



OUTDOOR – included outdoor temperature sensor connects here. If sensor is not
connected, ecosmart assumes coldest temperature is present
