Operating Rain Bird® ESP Irrigation Controller.
Step 1.
To set the controller to automatic operation, turn the dial to AUTO. The display
will show the current day and time until the next scheduled automatic start.
When a program is running, the display will show the station currently turned on
and the minutes remaining on its run time. When the entire program is complete,
the display will change back to the current day and time.
If you forget to turn the dial to AUTO, the controller will eventually set itself to automatic operation. The only setting that prevents automatic operation is OFF (see step 2).
Step 2.
To turn the controller off and prevent all watering, set the dial to OFF. The
display will show the current day and time. In addition, the right hand minute
digit will blink to show that the controller has been turned off. The OFF
setting can be used during rainy weather, seasonal shutdown, or system
maintenance.
Battery Replacement - Rain Bird® ESP Irrigation Controller.
Features a rechargeable battery backup, which will preserve
the controller's program in the event of a power failure. A fully charged
battery will maintain the controller's program and keep current time for up to
three days.
However, the battery cannot operate the system.
To replace the battery:
Step 1.
Open the controller door and swing the face panel out on its hinges from right
to left.
Step 2.
Remove the old battery from the battery holder and disconnect it from the
battery clip.
Connect a new 9-Volt rechargeable,
NiCad Battery to the battery clip. Then
insert the battery into the battery holder [ Charge the Battery before
installing it ].
CAUTION. DO NOT use 9 Volt alkaline batteries. They may burst or leak when
subjected to the continuous charging circuit of the ESP.
Use NiCad batteries only.
