Raritan Smart Toilet Control Circuit Board

The Raritan Smart Toilet Control Circuit Board (STC) is a controller for flushing toilets that optimizes water use without compromising flush quality. It is designed for boaters who want a genuine replacement STC board with a controller, panel, and 7 feet of cable included.

The control automatically starts a flush cycle when normal or water-saver buttons are pressed, with water-only and empty-only buttons limited to an 8-second run time each. Flush timing for initial fill, discharge, and final fill is fully programmable from the panel, which also shows holding tank full status when wired, and the unit is reverse polarity protected with automatic recovery within 10 minutes.
