Wiring the Controller
2
Interface to the Irrigation
Controller
!
This unit is designed to be installed in
conjunction with 24VAC circuits only. Do
not use with 110 or 220/230 VAC circuits.
!
The Controller Interface has 4 wires that
must be connected to the irrigation
controller / timer. If your timer does not
have an internal 24VAC power source,
you will need to splice the red and black
Controller Interface wires to a 24VAC trans-
former (example: Rain Bird part number
63747301S).
