Frequently asked questions

The IRC valve uses a PIR sensor to detect movement in the washroom. When movement is detected, the valve activates a 30-minute cycle, allowing water to flow into the urinal cistern. If no movement is detected during the last five minutes of the 30-minute cycle, the valve will close. If movement is detected during these five minutes, a new 30-minute cycle is activated. If no movement is detected for 12 hours, the IRC will activate a hygiene cycle.

The hygiene cycle is a flush that occurs after 12 hours of inactivity to ensure the urinal is kept clean and hygienic.

You can adjust the flow rate of the valve by turning the flow regulator on the bottom of the solenoid. Turning the screw clockwise reduces the flow rate, and turning it counter-clockwise increases the flow rate. The cistern should flush once every 30 minutes, ideally.

The IRC valve can be powered by either batteries or mains electricity. You can also choose to power it by both, which will provide backup power if the mains supply fails.

To test the IRC valve, press the test button. This will activate the valve test mode, which will cause the valve to open and close five times. The sensor test mode will run for one minute, and body movement will cause the amber LED to flash. After one minute, the sensor test mode will finish, and the sensor will revert to normal operation.
