This is a programming issue and is usually caused by multiple start times being set incorrectly.

Remember: Set only one start time for Program A.
This ensures the system runs only once per day schedule.

Start times 2, 3, and 4 in Program A should be set to OFF.
All start times in Programs B, C, and D should also be set to OFF.

Otherwise, the system may run multiple watering cycles per day.

All controllers have the ability to run multiple programs, typically labeled Program A, B, C, or D.

In certain situations you may want different areas of your system to run on different days or times.
For example, if your water supply comes from a well on a large property, you may run half the system on odd days and the other half on even days.

Program A might run stations 1 through 8 on odd days, while Program B runs stations 9 through 16 on even days.

However, we generally do not recommend using multiple programs because it can create start time conflicts. For example, Program A may start at 2 AM and run for three hours, finishing at 5 AM, while Program B could be scheduled to start at 4 AM. This can interrupt Program A before it finishes its cycle.

Station:
A station (also called a zone) is a section of your irrigation system controlled by a valve. The valve opens and closes according to instructions from the controller.

A typical residential system has 6 to 8 stations. These may correspond to different landscape areas such as the front yard, rear yard, shrub beds, or lawn areas.

Station Run Time:
This is the number of minutes a station will operate.

Typical recommendations:

• Sunny lawn areas: about 20 minutes
• Shaded lawn areas: about 12 minutes
• Shrubbery: 8 minutes, but not more than 12 minutes

A run time of 0 minutes means the station will not operate.

A Start Time is the time of day that your sprinkler system begins running.

Normally, only one start time is required for each program.

Multiple start times (1, 2, 3, or 4) will cause the system to run multiple watering cycles in a day.

Multiple start times are occasionally used for situations such as newly installed sod that requires frequent watering.

You can manually operate either a single station or all stations from the controller.

Simply select the station you wish to operate and turn the dial quickly to Run (Auto).

The controller allows you to manually run all stations in sequence.

This is helpful when testing the system or verifying that all sprinkler heads are working correctly.

Select the desired station or cycle and turn the dial to Run (Auto) to start the sequence.

You can manually select the days on which your irrigation system will run.

For example, you may choose specific days such as Monday, Wednesday, and Saturday depending on your lawn’s watering requirements.

Instead of selecting individual days, you may set the controller to water on odd or even calendar days.

This is useful when watering restrictions are based on municipal water regulations.

The pump feature is typically not used in most residential systems and should usually be left unchanged.

In special cases where a property uses an alternate water source such as a pond or lake, a booster pump may be activated using this feature.

The Rain Sensor Bypass switch should normally remain set to ACTIVE.

When the rain sensor detects rainfall, the display may show SEN OFF, meaning the system will not run automatically.

To temporarily water during rain sensor activation, move the switch to BYPASS.

Seasonal Adjustment allows you to increase or decrease watering times for all stations by a percentage.

Example:

• Setting 150% increases watering time by 50%.
• Setting 75% reduces watering time by 25%.

This feature helps adjust watering schedules during extremely hot or cool weather without changing individual station run times.
