Product description, general
The FKA control unit (hereinafter referred to as the control unit) controls a KESSEL backwater valve with
motorised lock. The level sensor switching signal for the wastewater level is processed electronically. An optical
probe is used as a level sensor.
A level sensor detects when the wastewater builds up in the sewer system up to the backwater valve and triggers
the motor drive of the backwater flap (close). The control unit's battery voltage takes care of this in the event of a
power outage.
The backwater flap can be opened and closed manually.
