Concealed Weesens sensor
The adhesive sensor is installed out of sight on the concealed surface of the ceramic bowl. It detects use through the ceramic and is protected from external interference. The system calibrates automatically when first powered on.
How it works
- When the sensor detects liquid containing salts in the bowl, it starts a pre-flush.
- Once use has finished and liquid stops entering the bowl, the main flush begins.
- The solenoid valve controls the water supply for each flush. SmartDelay may introduce a short activation delay.
- After 24 hours without use, an automatic flush replenishes the trap water seal.
Integrated overflow protection helps prevent overfilling.
Power supply options
- Four AA batteries: battery compartment and holder included; batteries not included.
- USB power from a suitable power bank or a 5 V USB mains adapter; USB cable included.
- Optional KG-A469 external power control unit.
- Optional KG-A448 water-powered generator.
