⚠ Note:
1. Water Pressure Requirements:
The controller cannot be used with water tanks or unpressurized water sources. A minimum water pressure of 1 bar (14 psi) is required for the solenoid valve to function properly; insufficient pressure may cause the valve to fail to open or only partially open.
2. Low Battery Alert:
When the battery voltage is low, the display will flash to indicate a low-power warning. At this point, the controller will not execute new irrigation tasks. You can manually turn off the system by pressing the 'OFF' button.
3. Automatic Mode Switch:
After manually stopping irrigation, the system will automatically switch back to the programmed mode after approximately 8 seconds.
4. Key Operation During Use:
When the controller is running, only the “OFF” button is functional. All other buttons are disabled to prevent accidental changes.
5. Frost Protection: During winter, if outdoor temperatures drop below 0°C (32°F), move the controller indoors to avoid freezing and cracking.
