Each 24 VAC electric valve is equipped with two black cables. The fi rst one identifi es the number of
the area and it will be connected to one of the outputs numbered in the terminal compartment and
the second one is the common cable that will be connected to the Exit C in the terminal compart-
ment along with all common cables of all electric valves.
The cables of the 24 Vac electric valves have no polarity. Connect the sensor wires to two cables in
output SENSOR. For version INDOOR connect transformer’s cables to the 24-vac input.

• If the distance between the timer and valves is
less than 700 feet (210 M), use
WaterMaster® sprinkler wire or 20-gauge
(AWG) plastic jacketed thermostat
wire to connect the timer to the valves. If the
distance is over 700 feet (210 M),
• use 16-gauge (AWG) wire. Terminals accept
up to 14-gauge wire. The wire
can be buried in the ground; however, for more
protection wires can be pulled
through PVC pipe and buried underground. Be
careful to avoid burying the wires
in locations where they could be damaged by
digging or trenching in
the future.
• Each valve has two wires. One wire is to be
connected as the common. The
common wires for all the valves can be connec-
WIRING THE ELECTRIC VALVES
ted together to one common wire
CONNECTING VALVE WIRES TO THE
TIMER
• Remove the terminal compartment cover.
• Strip _” (6mm) of the plastic insulation off the
end of each wire.
• Determine which valve you want to connect to
which station. Connect each
valve wire to its station terminal (labeled 1-6) by
inserting the bare wire fully into
the terminal.
going to the timer. The other valve wire is to be
connected to the specifi c station wire that will
control that valve
• All wires should be joined together using wire
nuts, solder, or vinyl tape. For additional protec-
tion to waterproof connections a WaterMaster®
grease cap can be used
• To avoid electrical hazards, only one valve
should be connected to each station (Note:
Only one wire can be installed into each termi-
nal. If more than two common wires are used
in your system, splice several together so only
one wire runs into each of the COM terminals.
Protect the splice connection with a wire nut.)

• It will be necessary to open the terminal to
allow for wire insertion or removal.
To do this you will need to use a small phillips
head screwdriver.
• Connect the common wire to the terminal
labeled “com”
CONNECTING THE TRANSFORMER
• With the wiring terminal shroud off, fi nd the
two terminal holes labeled “24vac”.
Make sure the transformer is not plugged in.
Insert one of the two power leads
from the transformer into each terminal.
• It will be necessary to open the terminal to
allow for wire insertion or removal.
To do this you will need to use a small phillips
head screwdriver.
• Plug in transformer
WARNING: DO NOT LINK TWO OR MORE
TIMERS TOGETHER WITH ONE
TRANSFORMER.
• Slide the shroud back on.
RAIN SENSOR
• A rain sensor or other type of micro-switch
weather sensor may be connected to
the controller. The purpose of the sensor is to
stop watering when precipitation is
suffi cient.
