Seven buttons with the center four buttons (left, right, up, and down arrows) are used to select or modify a program parameter. A large button accepts the parameter change and moves or skips to the next step or icon. The upper right button manually powers the timer on or off while the upper left button is used to stop irrigation.

Recommendations: Wrap all fittings with Teflon tape. Do not use pipe cement on the valve as it will damage the valve thread and void the warranty.

Battery installation

This timer requires two AA batteries (alkaline battery recommended)

  1. To install the batteries, unthread the gray battery compartment cover on the front side of the timer and insert two AA batteries. The polarity is marked for direction on the back of the timer.
  2. Thread battery cover clockwise to close.
  3. If the timer has been programmed, you have a safe period of 60 seconds to replace the batteries before losing the current time/date.


  1. Shut off the water supply.
  2. Remove the manual stem from the existing valve. If you are converting an anti-siphon valve, temporarily remove the anti-siphon cap (you will need to install the actuator and the cap together).
  3. Replace any existing worn washers with the new ones provided.
  4. Install the timer with the actuator into the manual valve; using a wrench, tighten firmly, but do not over tighten.
  5. Rotate the flow control clockwise until completely closed.
  6. Turn on the main water supply.
  7. Test the timer using the manual on/off button located on the upper right side. Press the button once. A click will be heard indicating the valve is open (a manual operation icon and icon indicating the valve is open will appear on the upper and lower right side of the screen).
  8. Now, rotate the flow control counter clockwise, one turn at the time until the valve is operational and all sprinklers/sprayers are working evenly and to your satisfaction.
  9. Press the manual on/off button again to turn the timer off. A click will be heard indicating the valve is now close (The manual icon will disappear and the valve will close.
  10. Program the timer.
    NOTE: If water continues to flow, turn the flow control slowly clockwise a 1?4 turn at the time. Repeat steps 5-9 if necessary.
    Review the instruction manual included with the unit for details
    Adding a rain sensor or any other closed contact sensor
