Installing The Decoders - Hunter X-Core Owners Manual And Programming Instructions

iNsTALLiNg ThE DECoDErs

1. Controller power must be OFF when installing decoders in
the two-wire path.
NoTE: Decoder wire runs and connections
must be completely waterproof. Decoder
wiring is more critical than "conventional"
24 vAC solenoid wiring. follow
instructions closely!
2. Select the decoder location (unless you are replacing an
existing decoder). Decoders should be within 100 feet/33 m
of the solenoids they will operate. Decoders are waterproof,
but should be installed in a valve box to facilitate future
service and increase longevity.
3. Locate the two-wire path. These are the red and blue wires
coming from the controller. The wire path must be cut to
insert decoder wiring, unless you are replacing an existing
decoder.
NoTE: be sure to leave enough slack in the wire
path to allow easy connection of the decoder and
to allow for contraction of wiring due to
temperature changes. hunter recommends at least
5 feet/1.5 m slack for each decoder to allow it to
be removed from the valve box completely for
installation, service, and inspection.
