Step 3. Connect Valve Wires To Timer
Valve Connections
A
Use direct burial cable to run wiring from the timer to valves
in the field.
B
Connect a color coded wire from the direct burial cable to
either wire on the valve.
C
Connect the remaining wire on each valve to a “common"
wire which then connects to the timer.
NOTE:
Use water-tight connectors for all wire splice connec-
tions. Depending on your landscape setup, you may need to
run extension wires for the power and common connections.
Timer Connections
A
Use a wire stripper to strip away approximately 1/4" of insu-
lation from the end of the valve wire.
B
Push the exposed end of the color coded wire from each
external valve (or zone) into the corresponding zone number
on the terminal block.
NOTE:
To insert or remove a wire, use a screwdriver to press
down on the connection release.
1/4"

WARNING:
To prevent damage to the timer, connect only
ONE valve to each open zone slot on the terminal block.
C
Connect the common wire to one of the
COMMON
slots on
the terminal block.
D
Check that all wiring connections are secure.
NOTE:
Do not remove the yellow jumper wire on the ter-
minals marked
RAIN SENSOR
unless you’re connecting an
optional rain sensor. See "Rain Sensor" on page 3 for
more information.
