2. Safety Information
Please read all safety information before installing or operating the controller. Failure to follow these instructions could result in injury or property damage.
- This controller is designed for indoor use only. Do not install outdoors or in areas exposed to water.
- Ensure the power supply is disconnected before performing any wiring or maintenance.
- All electrical connections should be made in accordance with local electrical codes.
- Do not attempt to repair the unit yourself. Refer all servicing to qualified personnel.
3. Setup and Installation
3.1 Mounting the Controller
Choose a suitable indoor location near a standard 120V AC electrical outlet. Avoid areas with extreme temperatures or direct sunlight.
- Mark the desired mounting location on the wall.
- Install two mounting screws (not included) into the wall, leaving approximately 1/8 inch (3 mm) of the screw head exposed. The screws should be spaced vertically to align with the keyhole slots on the back of the controller.
- Hang the controller on the screws.

3.2 Wiring the Controller
Before wiring, ensure the power adapter is unplugged from the electrical outlet.
- Common Wire (COM): Connect the common wire from your sprinkler valves to the terminal labeled 'COM' on the controller. This is typically a white wire.
- Zone Wires (1-6): Connect each individual zone wire from your sprinkler valves to the corresponding numbered terminals (1 through 6) on the controller.
- Rain Sensor (Optional): If using a rain sensor (sold separately), connect its wires to the 'SENSOR' terminals. Ensure the rain sensor switch inside the controller is set to 'ON' if a sensor is connected. If no sensor is used, keep the switch 'OFF' and ensure the jumper wire is in place between the sensor terminals.
- Power Connection: Plug the included 24V AC transformer into the '24VAC' terminals on the controller. Then, plug the transformer into a standard 120V AC electrical outlet.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or no power. | No power to the outlet; faulty transformer; loose wiring. | Check outlet with another device. Ensure transformer is securely plugged into controller and outlet. Verify 24VAC wiring. |
| Sprinklers do not turn on. | Controller is OFF; rain delay active; wiring issue; valve problem. | Turn dial to AUTO. Check if rain delay is active. Verify common and zone wiring. Manually test valves at the valve box. |
| Only some zones water. | Loose zone wire; faulty valve for specific zone. | Check wiring for the non-working zones. Test the specific valve manually. |
| Controller waters at wrong times. | Incorrect time/date; incorrect program settings. | Verify current time and date. Review start times, run times, and watering days for all programs (A and B). |
