which you want to program. Having two programs is like having two controllers; you
can water lawns and shrubs on different days or separate drip irrigation stations from
sprinkler stations. Because the "A" program has the default settings, it is best to use
"A" as your primary program and set it first, then set schedule "C" if you need the sec-
ond program.
VARIABLE DAY CYCLE
The EZ1-D Controller comes from the factory with a preset 7-day cycle. (This means
the controller will operate as programmed for 7 days, then repeat the cycle beginning
with day 1.)
If you want a 3-day cycle, for example, program days 1,2 and 3 only as above, and
then proceed as shown below.

TRANSFORMER CONNECTION
Attach a 3/4" conduit to the left most wiring hole in the bottom of the controller. Route
the power wires through the conduit and into the wiring cavity.
Use wire nuts to connect the "NEUTRAL" wire to the white transformer wire and the
"HOT" wire to the appropriately colored wire on the transformer. Use the "BLK" wire
for 220V, the "BRN" wire for 240V and the "ORN" wire for 260V.
Tape the two unused transformer wires so that they can't make contact with each
other or with the conduit. See the wiring schematic provided on the body of the 50 HZ
transformer and the figure below.

IN CASE OF TROUBLE, CHECK HERE
Sometimes when problems occur, they can be easily solved by carefully checking
some seemingly apparent, but often overlooked possibilities. Check here before you
call your professional contractor or Rain Bird distributor. It could save you time and
money.
IF YOU'RE HAVING THIS KIND OF
TROUBLE CHECK THESE THINGS:
• Automatic cycle does not occur • If display is blank, check fuse in EZ1.
• If last digit blinks, EZ1 is in the Rain Shut-
Down mode.
• Entire display is blank • Check fuse in EZ1; it probably needs replace-
ment.
• Entire display blinks • 9V battery needs replacing. After new battery
is installed, reprogram controller.
• Last digit in display blinks • EZ1 is in the Rain Shut-Down mode.
• Last two digits in display blink • EZ1 is counting down the time remaining on
station currently in operation.
• Clock loses (gains) a few minutes
every week or month • Intermittent power fluctuations are most likely responsible. Simply reset clock to correct time.
• Fuse blows too often (display goes
blank) • There is a short in the wiring between the controller and the valves.
Have bare wires, non-water tight connections,
and/or bad valve solenoids replaced.
