Functions
- Power on, the LED indicator flashes four times.
- After flashing four times, the sensor circuit will shut off the solenoid valve one time and will return to standby status.
- Once in sensing range, the LED indicator flashes one time per 0.7 seconds.
- Pre-flushing: Sensing two seconds, flushing two seconds.
- Flushing:
- Water Saving Flush: When sensing ＞2seconds and ＜20 seconds, it flushes water 4 seconds after user leaves.
- Full Flush: When sensing 2 seconds ＞ 20 seconds, it flushes water after 6 seconds.
- Auto Detect Mode: Sensing continuously exceeding 3 minutes, sensing distance will be shortened automatically not to detect. After stop sensing exceeding 2 minutes, sensing distance will be self-adjusted to optimum sensing range.
- Trap seal protection: It will flush water 4 seconds automatically every 24 hours if kept in unused status to avoid odour returning once the trap dries.
- Low battery indicator: when input voltage lower 4.4V, sensor circuit will be in alarm status and shut off solenoid valve automatically. While sensor detects sensing object, the LED will flash red three times quickly per second without flushing
when without sense, the LED will flash red one time per five seconds. After replacement of the battery, the alarm will be disappearing automatically.
