Connect one wire from each valve to the desired
corresponding number on the terminal.
Connect the remaining valve wire from all the valves
to the “Com” or common terminal. It is suggested
to use a dierent color wire for the common wire
to help keep organized. “Common” wires may be
bundled or wired together with all other common
wires from all the valves to the “Com” terminal of
the controller.
CONNECTING VALVE WIRES TO CONTROLLER
Locate controller within 5 . of a standard electrical
outlet that provides continuous, uninterrupted power.
Do not install controller within 15 . of a pump, pump
start relay or any high voltage junction boxes or elec-
tric motors.
