Operating mode
The motor-powered flap is open during normal operation. If the pres‐
sure switch registers the backflow of water, the motor-powered flap is
closed, the following display appears [Back pressure] and a signal
sounds every 10 seconds. The use of the drainage equipment is not
possible during this time. A battery emergency power supply ensures
the functionality of the system even when the 230 V mains power supply
fails.
Using the manual actuator, the backflow trap can be closed manually
and independently of the motor-powered flap.
