NOTE
: This unit is designed to be
installed in conjunction with 24VAC
circuits only. Do not use with 110 or
220/230 VAC circuits.
d
b
NOTE
: 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 transformer.
Controllers with sensor inputs (with
or without pump start / master
valve)
1.
Disconnect power to the irrigation
controller.
2.
Connect the red and black wires to
the 24 volt AC power on the irrigation
controller.
3.
If present, remove “jumper wire” between
sensor terminals.
4.
Connect the white and green wires to
the sensor inputs.
5.
Reconnect power to the irrigation
controller.

NOTE
: Ensure the sensor switch on
the irrigation controller panel is in the
active position.
Controllers with no sensor inputs (with
or without pump start / master valve)
1.
Disconnect power to the irrigation
controller.
2.
Connect the red and black wires to the
24volt AC power on the irrigation controller.
3.
Disconnect the wires from the Common
terminal on the controller.
4.
Connect the green wire to these
disconnected wires using a wire connector.
5.
Connect the white wire to the Common
terminal on the controller.
6.
Reconnect power to the irrigation
controller.
