Understanding Zones
This is a two zone timer allowing you to water two different areas from the
same faucet.
Each zone can be programmed with up to four different start times.
You can use the PLANNING TABLE provided on the back of this sheet to
help organize your watering schedule for each zone.
Installation of the Timer
Attach the timer to an outside faucet and turn on the water. The water must
be left on while the timer is attached to the faucet for your timer to operate.
NOTE: You may choose to program your timer before or after attaching it
to the faucet.

SET CLOCK: “Set Current Time and Day”
The Water Timer default setting is a 12-hour mode (AM/PM). To ensure
correct timing, look for either AM or PM to the left of the time. To switch
between 12-hour (AM/PM) and 24-hour (military time), hold the button
for 5 seconds. 12-hour mode shows AM or PM while 24-hour mode does
not. Note: Changing time mode will erase all programs.
Before setting your watering times, you must rst set the current time and
day of the week. When the batteries are rst installed, the arrow in the
screen will point to CLOCK. If it is not in that
position, press the button until the arrow
is pointing to CLOCK.
On your screen, a ashing box will appear
around the SU. Simply set the timer to the
current day by pressing the and buttons
on the touchpad until the square is on the
correct day. Once the correct day has been
indicated, press the button.

until the correct time appears on the screen, and then press .
Press the button (at the top of the touch pad) to move to WATER DAY.

START WATER: “What time-of-day do you want to water?”
You can select up to four independant start times (CYCLE A, B, C, D). With
the arrow pointing to Start Water on your screen, CYCLE A should be
highlighted, use the and buttons to select the rst watering time.
If you want to set another START WATER time, press to move to
CYCLE B. Repeat the process above to set the next START WATER time.
You may select up to four START WATER times.
When you have set all desired START WATER times, press
the
button to move to HOW LONG.

HOW LONG: “Set the length of each watering cycle.”
With the arrow pointing to HOW LONG, use the and buttons to select
the length of each watering cycle. After setting HOW LONG you want to
water during a selected cycle, press to move to the next cycle. Repeat
until HOW LONG has been set for each cycle.
HOW LONG can be set for up to 360 minutes (6 hours) for each watering
cycle. The Cycle length cannot overlap the next START WATER time.
Note: You can only select Watering Cycles if you have set a start time in
Step 5 above.
We recommend replacing batteries when the indicator reaches
