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.

Battery Installation & Assembly
Remove the battery holder from the back
■
of the Timer Control Unit. Insert two AA
alkaline batteries (Do not use rechargeable
batteries) as indicated on the battery holder.
Replace the battery holder, making sure that
it is firmly and securely placed in the Timer
Control Unit.
Note: Do not use your timer when the air
■
temperature is below 40°F (4.5° C). When
storing your timer, be sure it is in a dry place
and protected from frost.
We recommend replacing batteries when the indicator reaches
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 DATE/TIME: "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), under
OFF hold the OK BUTTON for 10
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 first set the current time and
■
day of the week. When the batteries are first installed, the arrow in the
screen will point to DATE/TIME. If it is not in that position, press the MENU
BUTTON until the arrow is pointing to DATE/TIME.
On your screen, a flashing box will appear around the SU. Simply set the
■
timer to the current day by pressing the -/+ BUTTON until the square is on
the correct day. Once the correct day has been indicated, press the OK
BUTTON.
To set the time, press the -/+ BUTTON until the correct time appears on
■
the screen, and then press OK BUTTON.
