Test for flow accuracy:
This is an important step to insure that unit is working properly. Im-
proper flow may affect the capacity of the system to effectively filter water in critical landscape
areas.
Per piping Illustration 2a or 2b (page 3) test ports have been provided to insure accurate
flow characteristics. Slowly open these test ports while indexing master irrigation controller
through its zone settings. Verify flow as follows:
1.
For those zones where filtration is desired:
Test port 1: should indicate pressure. Test port
2: should indicate pressure. Test port 3: should be non
-
pressurized.
2.
For those zones where no filtration is desired:
Test port 1: should indicate pressure. Test
port 2: should indicate pressure. Test port 3: should be non
-
pressurized.
Set Current time of day: (See Illustration 7)
Press and hold either the Up or
Down buttons on control(s) until the programming icon replaces the service
icon and the display reads TD. Adjust the time with the Up and Down buttons.
When the desired time is set, press the Extra Cycle button to return to normal
operation. If no buttons are pressed the unit will return to normal operation af-
ter five seconds.
User Programming: (See Illustration 8)
Press and hold the up and down ar-
row buttons for five seconds while in service until the programming icon re-
places the service icon and the display reads DO.
Set days override
:
(See Illustration 9)
It is critical to synchronize this set-
ting with the setting on your irrigation controller.
When programming your
irrigation controller and establishing the times and days for irrigation cycles to
operate, you must choose a consistent interval setting (ie; every day, every 2
days, every 3 days, etc). The days override setting should be synchronized to
match those days (intervals) so regeneration takes place following each cycle of
irrigation. When complete, press the
“
Extra Cycle
”
button, and the control will indicate RT
2:00, indicating the mode for regeneration time of day setting.
Set regeneration time of day:
Choose a time of day that will be followed by at least a 2 hour
window where the irrigation system is sure to be in standby mode. This time should also be dif-
ferent from regeneration periods for any other water treatment equipment (i.e., water softener)
to insure adequate pressure is available during its entire regeneration cycle (approximately 2
hours). Enter this time (AM or PM) by pressing the up and down arrows to select
.
IMPORTANT NOTE: WHEN SETTING UP DUPLEX SYSTEMS, THEY MUST NOT
REGENERATE DURING THE SAME WINDOW OF TIME. IT IS CRITICAL THAT
THESE TIMES ARE SET AT LEAST 2 HOURS APART FROM EACH OTHER, AND
DURING A 2
-
4 HOUR PERIOD WHERE THE IRRIGATION SYSTEM WILL RE-
MAIN IN STANDBY.
Control programming is now complete. Press the
“
Extra Cycle
”
button, and the control
will save the settings, exit from user programming mode, and resume normal operation.
