- Solid Blue - Normal operation, "Touch" mode is activated.
- Flashing Blue - Normal operation, the hands-free mode is activated.
- Solid Red - Warning mode - Replace batteries as soon as possible. While the water is running Solid Red LED is illuminated. When the water is off, the Red LED flashes once every 5 seconds. The faucet operates normally, solenoid valve is open.
- Rapid Flash Red - Alert Mode - Battery Failure Imminent. The Red LED flashes once a second. The first time the faucet is used, the Red LED will turn ON, the solenoid valve will be opened and remain open. The manual valve must be used until the batteries are replaced.
- Solid Red - Lockdown Mode - Replace Batteries. Extremely Low Batteries - The RED LED is ON, and water will not flow. The solenoid valve is closed and faucet will not operate until batteries are replaced.
- Long Flash Red (2 seconds on / 2 seconds off) - Board error, replace electronics kit, RP53230 See manual bypass of electronics section of Installation instructions.
