Locate
the
common
wire
to
the
solenoid
valves
and
the
common
wire
lead
to
the
coil
of
the
relay
that
starts
the
pump.
If
these
two
wires
are
connected
to
the
“common”
terminal
on
the
controller,
disconnect
both
of
them.
Twist
these
two
wires
together
along
with
one
wire
from
the
rain
sensor
and
secure
with
a
wire
nut.
Attach
the
other
wire
of
the
rain
sensor
to
the
“common”
terminal
on
the
controller.
Once
the
rain
sensor
is
mounted,
run
the
wire
to
the
controller,
using
wire
clips
every
few
feet
to
fasten
it.
If
an
extension
to
the
wire
provided
is
needed,
use
the
following
table
to
determine
the
minimum
wire
gauge
needed:
CHECK
TO
VERIFY
CORRECT
WIRING
Turn
on
one
zone
of
the
sprinkler
system
that
is
visible
while
you
are
in
reach
of
the
rain
sensor.
Manually
depress
the
manual
test
pin
at
the
top
of
the
rain
sensor
until
you
hear
the
switch
“click”
off.
The
sprinkler
zone
should
stop
instantly.
If
it
does
not,
check
wiring
for
correct
installation.
Note:
The
manual
activation
cycle
of
some
controllers
bypasses
the
sensor
inputs.
If
the
Rain
Sensor
is
connected
to
the
sensor
terminals,
you
will
need
to
run
an
automatic/timed
watering
program
for
these
types
of
controllers.
