Figure 2: Close-up of the control dials for Zone 1 and Zone 2.
5.1. Setting Watering Frequency
Use the 'Frequency' dial for each zone to set how often the watering cycle will occur.
- Turn the 'Frequency' dial to select the desired interval. Options typically range from 1 hour to 1 week (e.g., 1, 2, 3, 4, 6, 8, 12, 24 hours, or 2, 3, 4, 5, 6, 7 days).
- The timer will activate at the set interval after the initial setup or the last watering cycle.
- To reset the frequency or turn off automatic watering, turn the dial to 'Reset' or 'OFF' (if available).
5.2. Setting Run Time
Use the 'Run Time' dial for each zone to set the duration of each watering cycle.
- Turn the 'Run Time' dial to select the desired watering duration. Options typically range from 1 minute to 2 hours (e.g., 1, 3, 5, 10, 15, 20, 30, 60, 90, 120 minutes).
- To manually turn off watering, turn the dial to 'OFF'. To initiate immediate watering, turn the dial to 'ON' and then back to your desired run time.
5.3. Battery Indicator
The 'Battery Indicator' light will illuminate or flash to indicate low battery power. Replace batteries promptly when this occurs to ensure continuous operation.
6. Maintenance
- Battery Replacement: Replace batteries annually or when the low battery indicator activates. Always use fresh, high-quality alkaline batteries.
- Cleaning: Periodically clean the exterior of the timer with a damp cloth. Do not use abrasive cleaners or solvents.
- Winter Storage: Before the first frost, disconnect the timer from the tap and hoses. Remove the batteries. Store the unit indoors in a dry, frost-free location to prevent damage from freezing water.
- Filter Cleaning: Check the filter washer located at the tap connection point periodically for debris. Clean if necessary to maintain proper water flow.
