NETWORK/COMMUNICATION CABLES
AND CONNECTIONS
Use either a CAT3 or CAT5 Network/Communication cable.
Connect the network/communication cable first before
programming.
The maximum cable length between timers is 100 feet.
Connect each unit together from one communication port to
the next communication port. It does not matter which one
goes to the next one.

MASTER PROGRAMMING MODE
FLOW CHART
CAUTION
Before entering Master Programming, please
contact your local professional water dealer.
NOTE: Depending on current option settings, some displays
cannot be viewed or set.
Entering Master Programming Mode
1. Press and hold the Shift and Up buttons for 5 seconds.
Press the Extra Cycle button once per display until all
displays are viewed and Normal Display is resumed. Option
setting displays may be changed as required by pressing
either Up or Down button. Use the Shift button to move one
space to the left.
2. Depending on current valve programming, certain displays
may not be viewed or set.
NOTE: If the "D" button is pressed while in master
programming, no changes will be saved.
Exiting Master Programming Mode
1. Press the Extra Cycle button once per display until all
are viewed. Master Programming Mode is exited and the
normal display screen appears.
2. To exit the Master Programming Mode without saving
changes, press the Diagnostic button.
NOTE: If no keypad activity is made for 5 minutes while in
the Master Programming Mode, or if there is a power
failure, no changes will be saved, and the unit will go
back to the main display screen.
Resets
Soft Reset: Press and hold the Up and Down buttons for 25
seconds until 12:00PM (or 12:00HR) appears. This resets all
parameters except for the flow meter totalizer volume.
Master Reset: Hold the Extra Cycle button while powering up
the unit. This resets all of the parameters in the unit. Check
and verify the choices selected in Master Programming Mode.
NOTE: If the "D" button is pressed while in master
programming, no changes will be saved.

Trip Point 2 + 1 to 3999 lpm (Metric Format)
Trip Points 1, 2, and 3 (System 14 only)
This program step selects up to three Trip Points programmed
on the master timer only (Valve Address #1).
The actual required number of Trip Points in a system is one
less than the number of valves in the system.
Trip Point 1 represents the system flow rate at which a second
valve will be brought In Service or Standby.
Trip Point 2 represents the system flow rate at which a third
valve will be brought In Service or Standby.
Trip Point 3 represents the system flow rate at which a fourth
valve will be brought In Service or Standby.
Trip Point 1 Trip Point 2 Trip Point 3
Range:
1 – 997 GPM
U.S.: Value of Trip Point
1 plus 1 to 998
U.S.: Trip Point 2 plus
1 to 999
Range:
0001 – 3997 Lpm
Metric: Value of Trip
Point 1 plus 1 - 3998
Metric: Trip Point 2
plus 1 - 3999
Trip Delays 1, 2, and 3 (System 14 only)
This program step selects each Trip Delay time that is
addressed with each Trip Point and will be programmed on
the Master timer only (Valve Address #1). The Trip Delay time
represents a minimum amount of time the system flow rate
is required to be equal or greater than the Trip Points to bring
a unit In Service. It also is the minimum amount of time the
system flow rate is required to be less than the Trip Points to
remove a unit from In Service to Standby.
Trip Delay 1 Trip Delay 2 Trip Delay 3
