Operating Modes
The Casfuy PWL-300 offers three intelligent drinking modes:
- Sensor Mode: Water dispenses for 30 seconds when a pet approaches the fountain. This mode conserves battery life and water.
- Timer Mode: Water is dispensed for 60 seconds every 30 minutes. This provides regular access to fresh water while still being energy efficient.
- Continuous Mode: Water flows continuously. This mode requires the fountain to be plugged into a power source.
To switch between modes, press the mode selection button on the fountain. The LED indicator will change to reflect the selected mode.
