Shower Pump Control with Delay

This Scheiber relay module controls the shower drain and macerator pumps on many Jeanneau, Beneteau, and Lagoon boats. 

It is a clever device that has a built-in delay circuit to ensure that there is water present in the pump before the pump engages, and to be sure the waste water continues to pump all the way out of the boat.

Timeout setting pump drive: 2-3 secs.

Pump off delay: 5-6 secs.
