    high water sensor board has a primary voltage side. One leg connects to the primary leg; one leg connects to the short sensor pin in the top of the cylinder. A potential, somewhat less than primary, is picked up by the sensor at high water level, which “makes” the red/black circuit on the low voltage side. This creates a resistive loop across t ...
