This is a replacement power relay for your Atwood water heater. When the switch for Electric is turned on, power is sent from the board to the yellow wire. The yellow wire carries DC voltage to the relay in the back of the water heater. The 12 volt energizes the relay which sends the 110V AC to the element.
