Summary: Consumers will occasionally wish to
re-route their valve wiring, or extend it if the 9 ½
feet length is not adequate. Simple take care in
removing the wiring, and pay particular attention
to keeping the wiring as shown: Red wire (or
attached wire tied to the red wire) on the LEFT
and the White wire on the right.
If by accident you reverse this wiring you will
not harm the system, but the 'ON' and the 'OFF
function of the valve will be reversed. If turning
the moisture knob all of the way down turns the
valve 'ON' you have reversed the wires.
Notice: This terminal strip uses a small opening
and screwdriver. Take care in making sure you
re-install the wiring in the proper hole, and when
you tighten the wire back make sure that you
have good insertion into the hole. Mistakenly
shorting the two wires together, such as bare
wires of the white touching the red during valve
operation will short out the output transistors in
the controller, and it will fail. Shorting the wiring
is not covered by warranty, so be careful!
Always turn the knob all of the way down before
working on the wiring.
To extend the wiring, just pay attention to the
color coding and carefully remove the existing
cable from the drilled hole in the support
housing. Purchase additional wiring (at least 22
gauge, preferably larger. Then use an outdoor
rated splice to attach the existing cable to your
new cable. If needed, you may enlarge the hole
in the support housing to fit the new wire. It is
not recommended to enlarge the hole much as
it may crack the support housing. Most
hardware stores sell 22/2 stranded CM plenum
type cable that will fit into the existing support
housing hole. Do not extend more than 20 feet.
