Install your new timer by following these six steps:
STEP 1: SELECT THE LOCATION
A. Select an indoor location near a conventional 120 volt dual electrical
outlet.CAUTION: The timer should not be placed where it is exposed
to a temperature exceeding 55” Centigrade (130” Fahrenheit)
or on a circuit controlled by a switch. Malfunctions may result.
B. If the timer is adistancefrom the outlet, replace the supplied cord with
a similar electrical cord (available at hardware and electrical supply
stores).
STEP 2: MOUNT THE TIMER
A. Screw in a No. 8 screw at eye level, leaving the screw head extended 1/8"
B. Slip the keyhole opening on the back of the timer over the screw head.
C. Open the timer and install two screws through the holes in the wiring
compartment at the bottom of the timer.
NOTE: To install the timer on a plaster or masonry wall, use
plastic or lead shields to secure screws
STEP 3: WIRE THE VALVES
8
Place valve wiring underground where possible. (Under 800 feet, use
18 gauge, plastic jacketed, thermostat control wire; over 800 feet, use
14 gauge wire. This wire is available from your dealer in
2,3,4, 5,6,7,
and 8 color coded wires).
Run one common wire to all valves.
Solder all splices, or join them with wire nuts and seal with vinyl
cement or other waterproof cement.
IMPORTANT: The power transformer is protected by an elec-
tronic circuit breaker. Do not connect a combination of valves
requiring an inrush current of more than 1 AMP at 24 VAC. (Two
valves maximum).
STEP 4: CONNECT THE VALVE WIRES TO TIMER
A. Bring valve wires up through the hole on the bottom of the timer.
B. Connect the wire from valve number 1 to the terminal screw on the
timer marked
“1 “, valve number 2 to terminal “2”, and so forth.
NOTE: The terminal designation is marked on the inside of the
wiring cover.
C. Connect the common wire to the terminal marked “COMM”. (Fig. 1)
D. If using a water pump or master valve, refer to page 1 1 for instructions
and diagrams. (Fig. 2).
STEP 5: CONNECT THE TRANSFORMER
A. Connect the power leads from the timer to the plug-in transformer.
B. Attach one lead to each terminal screw on transformer. Be sure
terminals on cord do not touch.
C. Plug in transformer.
CAUTION: Use with supplied transformer ONLY!
STEP 6: CONNECT THE BATTERY
Battery will keep program in memory during temporary power failure.
A. Connect a 9 volt alkaline battery (not supplied) to the battery
connector in the wiring compartment of the timer box.
B. Place the battery in the wiring compartment.
C. Replace wiring compartment cover.
D. Replace battery at least once a year. More often if frequent power
failures occur.
CAUTION: DO NOT ALLOW THE
BATTERY CONNECTOR TO TOUCH THE
TIMER’S TERMINAL STRIP (DIRECTLY ABOVE THE WIRING
COMPART-
MENT).ALSO, DO NOT CONNECT OR DlSCONNECT VALVE WlRES WHILE
ANY ZONES ARE IN OPERATION.
NOTE: Check local codes to be sure wiring and installation will meet all
requirements.

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. Press
m
B. Press [q 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 m key repeatedly, or hold it down until the current minute
rolls up on the display.
Press the m and a keys one at a time for single digit
changes. Hold the / and m keys down for fast changes.
Once you have pressed the m key, you must press the (
or / key within 10 seconds. Otherwise, you must press
the l,,,il! 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 to water all the shrub or groundcover areas of the yard
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
j’:“,“‘l , m , and m , I’:“.“‘j 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 on
the letter “A” and the 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 m key. (The display will show “200A”).
Press the m key and hold it until the desired hour and “A” (AM) or
“P” (PM) is displayed.
Press the
m 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
m 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
m key, you must press the m or
m key within 10 seconds. Otherwise, you must press the m
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).

STEP 5: SET THE DAYS YOU WANT TO WATER
To set the watering days for each program:
A. Move the “DAYS” switch for “A” and "B" to the desired watering
day(s).“4” (every 4th day), “3” (every 3rd day), “2” (every 2nd day),
“1” (every day), or “OFF”.
Zones programmed to water on a certain day will be watered
sequentially, skipping those zones programmed to
“OFF”.
During watering, the zone number will appear on the left of the
display, and the zone’s run time will appear on the right. The
display starts at one minute and counts up to the total run time
before changing to the next zone to be watered.

If you plan on connecting timer to a well pump or master valve, use the
following instructions.
A. Bring two wires up through the same hole used for the valve wiring.
B. Connect one wire to the terminal marked “PUMP”.
C. Connect the second wire to the terminal marked “COMM”.
D. If a master valve is required, the two wires should then be connected to
a master valve, rated at 24 VAC and a current no greater than 9 VA.
E. If a pump start relay is required, connect the two wires to an auxillary
relay with a coil rated at 24 VAC and a current no greater than 9 VA. The
relay’s contact would then be wired so it would supply voltage to the
pump’s contactor. A qualified electrician can make these connections
for you.
Model SR-1 can be connected to the two wires and will directly
control a pump up to 2 HP at 240 VOLTS.
NOTE: The timer’s pump output will be turned on whenever a
zone is watering manually or automatically.

MANUAL WATERING TURNING OFF THE SYSTEM
To water your yard manually, move the “PROGRAM” switch to “MAN” When watering is not in progress, you can prevent automatic watering
for the zone you wish to water. The timer will allow only one zone at a time by moving the “DAY A” and “B” switches to “OFF”.
to be watered manually. If more than one program switch is placed in the
“MAN” position, only the lowest numbered zone will water. When the
switch is moved off the “MAN” position, the next lowest zone set on
“MAN” will start to water.
Manual watering is still possible, when the timer is in the
“OFF” mode.
The “MAN” setting will override any automatic or semi-automatic
watering cycle, including any cycle in progress.
NOTE: When manual setting is used, water will stay on until the
switch is moved. DO NOT LEAVE IT IN THIS POSITION!
SEMI-AUTOMATIC WATERING
If no watering is in progress, press the
m key to start a semi-
automatic watering cycle of all zones not set to “OFF”. To stop a semi-
automatic cycle, press
them key and then within 10 seconds press
the M key. The watering in progress will stop, and the display will show
“OFF” for 10 seconds before returning to the clock mode.
INTERRUPTING THE WATERING CYCLE
When an automatic or semi-automatic watering cycle is in progress
press
m to freeze the cycle at that point of the zone’s run time. The
display will alternately flash “PAUSE” and the zone’s number and run
time. To resume the watering cycle, press
m again, and the zone’s
count will continue.
NOTE: If a “PAUSE” is turned on and forgotten, the program will
automatically reset itself at midnight. The timer will then begin
with the first start time for the new day.
ELECTRONIC CIRCUIT BREAKER
If the timer detects a short circuit the shorted valve/zone will auto-
matically be turned off. The display will then alternately flash ” ” and
the shorted zone number and run time. The timer will continue to auto-
matically water the other zones and the following watering cycles, with
the display continuing to flash on the zone number with the short
circuit.
After repairing the short, press
m or any m key to return the timer
and display back to its current operating mode.
