| Instructions for the Rainbird ISA 304 irrigation timer
- Set the time and day by turning the programming wheel until the hour and day, hour and minute flash.
- Select one of the preset watering programs by turning the programming wheel to the preset times. The letter C will flash on the screen to indicate the changed default schedule.
- Turn the wheel to the seasonal setting.
- Press and hold the left and right arrow buttons simultaneously for at least 3 seconds. Until you see the word DELETED on the screen.
- Return the steering wheel to AUTO RUN.
A common reason for repeating a program is that it has a different start time. The start times determine the exact time the ESPMe timer will start watering and will also determine how many times the timer will water per day. With ESPMe you can set up to 6 start times per program.
With automatic seasonal adjustment, the Rain Bird server can monitor the local weather based on the programmed postcode. The Rain Bird server calculates a daily evaporation rate (ET) for each postcode and translates it into a corresponding seasonal adjustment value.
To adjust the Rainbird nozzles, rotate the nozzle left or right to change the direction of the water. To decrease the spray distance, use a flat blade screwdriver to turn the screw on the nozzle clockwise.
Try the following: Halve the irritation time for each area, but run the watering program twice. In other words, instead of watering each zone for 30 minutes, water each zone for 15 minutes and then run through each zone for another 15 minutes.
ProC only performs manual training
Cards. A common reason a controller repeats a cycle is because there are too many scheduled start times. Only one start time is required per active program; if the start time is different, the program will run again. Each station is assigned a program (A, B, C).
How to reset an irrigation system
STATION. A circuit on the controller that activates a single control valve in the irrigation system to control irrigation for a specific area.
The resulting number is the number of zones needed. For example, if each sprinkler head requires a flow rate of 1.31 GPM and you have 20, then you need a total of 26.2 GPM. If your system can only handle 16.67, consider using two zones to cover the same area of your farm.
Basic depth requirements
When a certain zone is activated, the sprinkler control can send 24 volts to the solenoid valve. The current then magnetizes a piston in the valve, which then rises and allows the water to flow into that part. Cheeky! The lawn is watered.
A pump start relay is an electrical device that allows the irrigation timer to communicate with the pump. This device is essential if a pump is used to supply water to the irrigation system. The pumps are designed for normal household electricity, the relay switches the irrigation timer to normal household voltage.
