SETTING THE CONTROLLER TO OFF

1. Turn dial to “OFF”.
When the dial is in the “OFF” position no watering occurs. The display will show “OFF,” the time of day and day of the week.
NOTE: Pressing any button will momentarily display the current “REVISION NUMBER,” “K-RAIN” or full display screen.

SET CONTROLLER TO RUN AUTOMATICALLY
1.Turn the dial to “AUTO”
When the dial is in the “AUTO” position the controller will run in automatic mode. The display will show the selected program, the day of the week and the time of day. The controller will turn on automatically to meet ANY programmed water schedules.

PROGRAM SELECT BUTTON

The Pro-LC controller has three separate programs, A, B and C. Multiple programs allow valves automatic operation with different watering days and start times.
You can program any valve to run in one or more of the three programs.

To select a program, press the PROGRAM select button on the front panel to select program A, B or C.

The display briefly shows the program selected.
The selected program then appears on the left side of the display.

Any programming instructions entered will apply only to the selected program.
Program C is by default an irrigation program. But when the lighting feature is used, program C will be for lighting only. See Pg. 15

RAIN SENSOR SELECT BUTTON

The purpose of a rain sensor is to stop automatic watering when sufficient precipitation has been reached.
The rain sensor select button allows the user to bypass the rain sensor. If a rain sensor has been installed, and BYPASSED has been selected,then BYPASSED will be displayed in the upper left corner of the LCD.
NOTE: When the rain sensor select button is in the ON position a rain sensor or wire jumper must be installed in order to run a program. Refer to page 26 for further details.

PROGRAMMING

As the program dial is rotated the display automatically changes. The flashing value within the display can be increased or decreased by pressing the DOWN or UP buttons. To go back or advance to the next value press the BACK or NEXT buttons.
Because of variations in plant watering needs the Pro-LC has three separate programming options; A, B and C. Each program is completely independent of each other and the controller will automatically stack programs that overlap. This allows for all programmed watering to occur because only one program will run at a time and in alphabetical order.
Only one start time per program (A, B or C) is required to operate all stations with a run time.
The controller automatically and numerically advances operation to the next station without the need for additional start times.
For additional watering, each program can be set with up to four separate start times. This allows for greater irrigating efficiency when all watering can’t be done during a single operation (cycle and soak).
NOTE: A program must contain at least one start time, watering day(s) and one station with a run time in order to operate.
