1. How do I put batteries into the timer? a. Locate the batter compartment on the back of the timer. Squeeze tabs and pull up on the battery tray. After placing (2) AA batteries in the battery tray, slide the tray into the timer. The tray will only fit into the timer one way. Firmly push down on the battery tray to ensure it is fully inserted into the timer. 2. What type of batteries can be used? a. It is recommended that (2) new alkaline or lithium ion be used at the beginning of each season. Do not use rechargeable batteries because they do not meet the minimum voltage requirements. 3. How long will batteries last? a. Lab testing of the timer showed that the batteries in the timer lasted in excess of 20,000 on/off cycles. However, we recommend that new batteries be installed at the beginning of each watering season. 4. How do you program the timer? a. The day and time are not set on this timer. The timer must be set at the time of day that the watering is to begin. If you want the watering to begin at 7:00 am, then the timer must be programmed at 7:00 am. To set the start time, turn the FREQUENCY dial to the desired setting. The frequency is how often you want the water to come on. Setting the dial to 1 means that the water will come on every hour (24 starts per day). Setting the dial to 48 means that the water will come on every other day. After setting the FREQUENCY dial, turn the RUN TIME dial to the desired setting. Run time is how long the water will run for, in minutes. Note: The Frequency must be a longer duration than the run time. 5. When will the water turn on and start watering? a. See the table below to see how many starts per day and when the watering will start. Frequency # of starts per day Watering will start 2 Hour 12 2 hour later 3
6 hours 4 6 hours later 12 Hours 2 12 hours later Week 1 watering cycle per week 1 week later 6. How do I change the frequency or run time? a. The frequency or run time can be changed at any time by simply rotating the dial to the new position. 7. Does changing the frequency or run time change the start time? a. No. Changes made to the frequency or run time will not change the start time. The dials can pass over the off and reset without affecting the start time. Changes are not made to the programming until AFTER the confirmation flash by the LED lights on the timer (about 2 seconds after stopping on the desired setting). 8. How do I change the start time? a. Set the FREQUENCY dial to the RESET position. The LED light will blink confirming the change. Follow the steps in question 4 to set the timer at the new desired start time. 9. How does the Manual Watering cycle work? a. The manual watering cycle is used to water your plants between automatic watering cycles. To run a manual cycle, rotate the top dial to the desired run length. The manual watering durations range from 3 to 90 minutes. After the manual watering cycle completes the timer will return to automatic mode. You do not need to return the dial to the RESET position. 10. How does the Rain Delay work? a. This timer has the ability to delay the start of the next watering cycle for 24, 48, or 72 hours. Rotate the top dial to the desired length to delay the start of the automatic watering cycle. After the rain delay cycle completes the timer will return to automatic mode. You do not need to return the dial to the RESET position. 4
11. Does the timer have hose or pipe threads? a. The timer has hose thread on both the inlet and outlet connections. 12. Can the timer be installed flat on the ground? a. No. It is recommended that the timer be installed above ground, directly to the hose bib. 13. What are the minimum and maximum water pressures that can be used? a. The timer requires a minimum of 15 psi water pressure to operate. The timer should not be used in locations with water pressure greater than 80 psi. 14. How do I winterize the timer? a. The timer should be removed from the hose bib at the end of each watering season. After removing the timer, remove the batteries and shake the remaining water out of the timer. The timer should be stored indoor until the next season. 15. Will the timer turn off when the batteries are low? a. Yes. The battery indicator light will show the power level of the batteries. Once the power gets low, the timer will shut the valve and will not run until the batteries are replaced. 16. My timer did not water. Why not? a. Before contacting Agrifim Technical Services, please check the following: i. Make sure the water is turned on at the hose bib. ii. Check the power level on the batteries. After the batteries are initially installed the timer checks the power level of the batteries. If the total voltage is less than 2.6 volts, the indicator light will blink repeatedly signaling a problem. After the initial battery level check, then timer will check the battery level to be sure that there is enough power to shut the valve. iii. Check that the batteries are correctly installed in the battery tray. 5
iv. The FREQUENCY dial must be set to a duration longer than the RUN TIME. The indicator light will blink until the frequency is increased or the run time is decreased. 17. How do I know if my battery power level is low? Batter Power Level Indicator Light Action High 1 blink every 4 seconds Low 2 quick blinks every 4 seconds Empty 3 quick blinks every 4 seconds 6
