INSTALLATION INSTRUCTIONS

RESET

When a PLUS4 board is added to a SmartZone™, press reset to
update the controller so it recognizes the additional zones. The reset
button is located on the back of the front panel.

PROGRAMMING INSTRUCTIONS

PROGRAMS
The SmartZone™ can operate a maximum of four programs. The
programs are labeled A, B, C and S. A, B and C are traditional
irrigation programs that are used to group plant material or zones of
like watering requirements (i.e. sun, shade, rotors, sprays, etc.) The
"S" stands for simultaneous. This program can run simultaneously
with the A, B or C programs.
The S program is designed for situations where you would like to run
two programs at the same time (i.e. a drip zone with a rotor zone). The
S program can be used as a forth traditional program, but be aware that
if any part of the S program's run times overlap with another program,
the controller will attempt to operate them at the same time.
NOTE: Be sure not to exceed the electric or hydraulic limitations of
your system when using the S program.

PROGRAMMING OVERVIEW

Before programming the SmartZone™, it will be helpful to become
familiar with some general programming guidelines.

• be sure the appropriate program letter is displayed when you are
programming; program changes are specific to the program
displayed on the LCD
• you do not have to wait for the LCD to return to status mode to
initiate the next programming step
• you can make programming changes while the controller is running
• if you change the time of day while the controller is running, the
program running will stop and the controller will water at the first
start time that occurs after the new time of day
• if you make any other programming changes, the controller will wait
until the current program is finished to incorporate changes
• when not running, the controller will display the program and next
start time that is scheduled
• when changing programs, there will be a 1-2 minute delay before
the LCD displays the next scheduled start time or displays the
current status (if a program(s) is running)
