Understanding Zones
n This is a four zone timer allowing you to water four different areas from the
same faucet.
n Each zone can be programmed with up to four different start times.
n 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

water must be left on while the timer is attached to the faucet for your timer
to operate. You may choose to program your timer before or after attaching
it to the faucet.
n NOTE: If water is continuously owing through one or more valves, see
Open Valves During Installation in the “Useful Tips” section for more
information.

SET CLOCK: “Set Current Time and Day”
n 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

for 5 seconds. 12-hour mode shows AM or PM while 24-hour mode does
not. Note: Changing time mode will erase all programs.

Warning: Intended for outdoor use only. Severe electrical shock could result if
water is sprayed into outlets or sources of electrical current. Do not use water
more than 115°F (46°C). Do not use when the ambient air temperature is less
than 40°F (4.5°C). When not in use, remove batteries, drain and store indoors
away from freezing temperatures.
Open Valves During Installation
Shaking during transportation can cause valves to be open. if this occurs, water
may run continuously through one or more valves during installation.
n Turn the water off.
n Remove the batteries. Wait for the screen
to go blank. Reinsert the batteries.
n Note: Removing the batteries will not
erase any existing watering schedules.
n Turn the water back on.
n If the problem persists, turn off the water.
Use the Manual feature to open and
close each valve 3 times.
Seasonal Storage
Freezing temperatures can cause water in
the timer to freeze and expand, damaging
the timer.

is frost in the forecast, turn off the water
and remove your timer from the faucet.
n Remove the batteries.
n Be sure to store the timer indoors, away

storing.
n Batteries should last about one season. A schedule with
more frequent watering times can cause the batteries to
drain faster.
