Built in 3/4" Plastic latching valve. Both ends thread are USA hose standard of NH-11.5. Plug in moisture sensor/Rain sensor. Including both "Moisture Control" and "Timer Control" modes, push mode key to switch between the modes. Can be powered by 4xAA Alkaline battery, solar panel with 4xAA rechargeable battery, or 100V to 240V AC adapter.

Feature under “Moisture control" mode:

One key push-hold to setup Dry control level, and one key push-hold to setup wet control levels.

Then the system will keep the soil moisture level within the set up range.

User can adjust wet/dry control levels on the screen.

Set maximum irrigation duration to prevent flooding by broken pipe.

Moisture sensor could be buried shallow or deep into the soil.

The LCD will in sequence show "Dry control %, Current %, Wet control %, Max (Duration)".

Feature under "Timer control" mode:

Uses the moisture sensor as rain sensor to prevent irrigation in the rain.

Set any sensitivity of the rain sensor as desired.

User can set up any length of irrigation duration as desired.

Set maximum moisture % of the rain sensor to prevent flooding by broken pipe.

The LCD will in sequence show "Interval, Duration, Max %(of rain sensor)".

How to operate:Push “"to turn on controller and choose the operating mode.A: “Moisture" mode, watering is controlled by moisture levels sensed by the built in moisture sensor.1.) Wait until the soil is just dry and ready for watering. Push and hold the "Dry CTRL" key until there is a beep.Then the built in valve will open and watering will begin. This dry moisture level will be remembered.2.) Wait until the soil is just wet enough to end watering, push and hold the "WET CTRL" key until there is a beep.The valve will close; this wet level will be remembered.3.) After this setup, the controller will automatically control irrigation between these two control points. The controller will show in sequence show the remembered "dry control %", "Wet control %", and the "current %".4.) User can push ""key to choose "Adjust dry control" or "Adjust wet control", and then push up/down keys to adjust the remembered dry/wet control levels.5.) User can push "" key to browse other setups, for example, the MAX irrigation length (default is 1 hour), set to other period or leave as is.

B: In "Timer" mode,

1.) Push “" key to choose setup "Interval" time, push up/down key to choose value.

2.) Push “" key to choose setup "Duration" period, push up/down key to choose value.

3.) Then the controller will automatically control irrigation according to the setup time schedules. The controller will show current moisture % if it has a moisture sensor.

4.) User can push “"key to choose "Rain sensor" setup. Put the rain sensor in a dry place to make rain sensor more sensitive to the rain and less sensitive to watering. Factoy default is 40%.
