Before programming, read all instructions carefully.
STEP 1: SET THE CLOCK TO THE CURRENT TIME
The timer’s clock features a 12 hour format - 12 PM represents noon;
12 AM represents midnight. The AM or PM setting changes at 12:OO so that
1159 AM progresses to 12:OO PM.
When the power is first turned on, the timer automatically displays a time
of “4OOP” (4:00 PM).
To set
the
correct time:
A . P r e s s
B. Press
key and hold it down until the current hour and A (AM) or
P (PM) rolls up on the display or repeatedly press key to advance the
the numbers digit-by-digit.
C. Press
key repeatedly, or hold it down until the current minute
rolls up on the display.
Press the
and
k e y s o n e a t a t i m e f o r s i n g l e d i g i t
changes. Hold the
and
keys down for fast changes.
Once you have pressed the
key, you must press the
or
key within 10 seconds. Otherwise, you must press
the
key again to make the changes.
STEP 2: SELECT THE RIGHT PROGRAM
The 446PRi timer has several options that allow SIMPLE, FLEXIBLE,
programming never before offered. The newest of these is the multiple
programs option which provides the ability to water individual areas of
any yard separately. These programs are displayed on the face of the
timer by the letters “A”, “B” 8 “AB”.
A simple example of how these programs might be used would be to use
the “A” program to water all the grass areas of the yard every other day.
Use the "B”program t o w a t e r a l l t h e s h r u b o r g r o u n d c o v e r a r e a s o f t h e y a r d
daily. The “AB” program would normally only be used when new grass is
being established and more than 2 start times per day are needed.
NOTE: Any of the zones can be set to water in any combination
within the “A” “B” or “AB” programs. Page #10 shows a
sample program.
Move the “PROGRAM” switch under each zone to the desired watering
day program, “A,” “B”
“OFF”, or “MAN” (for manual watering).
STEP 3: SET THE TIMES OF DAY YOU WANT TO WATER
Now that the program selections have been made, the times that each
program should start need to be set. This is done by using the “START” keys
located under the display. Note that there are 4 keys to choose from
,
,
and
,
There are 2 start times
for
all “A” zones and 2
start times for all “B” zones.
The two keys marked with the letter “A” will start all the zones where the
program switch islocated onthe letter “A” andthe sameis true forthezones
where the switch is located on “B”.
To
program the start times for “A” follow these steps:
A.
B.
C.
D.
E.
Press the
key. (The display will show “200A”).
Press the
key and hold it until the desired hour and “A” (AM) or
“P” (PM) is displayed.
Press the
key and hold it until the desired minute is displayed.
Repeat this procedure for all the remaining start times.
If any start time is not needed be sure to set it to the “OFF”
position. This is done by holding the
key until the word “OFF” is
shown in the display. This occurs just after “11 OOP”.
NOTE: If a program switch is placed in the “AB” position that
zone would start at every start time programmed. (Up to 4).
Once you have pressed a
key, you must press the
or
key
within 10 seconds. Otherwise, you must press the
key again to make the changes.
Leave enough time between start times to allow all zones to be
watered. If a start time produces a watering cycle that runs into
the next start time, the timer will automatically move the next
start time ahead to allow completion of the current watering
cycle. If a start time produces a watering cycle that runs past
midnight, any other start times programmed to start before
midnight will be cancelled.
Start times can be entered in any order. Watering cycles
progress by the time of day, not by start numbers. For example,
START 1A may actually be the last watering time of the day.
STEP 4: SET HOW LONG YOU WANT TO WATER EACH ZONE
Each zone can be set with a run time from 2 minutes to 99 minutes.
To
set the run times:
Move the switch under each zone to the desired watering time. (Place
the switches only
on
the minute marks, not
between
the marks).
