Joining the Communication Cable
Changing Jumper Positions
(Averaging readings from remote sensor)
If using multiple remote temperature/humidity sensors
in your application, refer to the photos showing the
need to change the jumper locations internal to the
control board on each remote sensor (up to three
maximum).
For the control to average all of the sensors utilized (if
more than one), the jumper must be in different
positions on the pins.
There three pin settings. To access the jumper:
1. Remove the two-set screws holding on the
plastic cover. This procedure allows the control
to go to each remote sensor in sequence to
average. Failure to perform this procedure will
result in the system reading only one sensor
and not the average of multiple sensors.
NOTE: If multiple sensors control the Wine
Guardian unit, change factory default in
configuration setting 10 to “averaging.” Obtain
access code from Air Innovations’ service
department to use in configuration 8 to reach
configuration 10.

IMPORTANT
Wine Guardian cooling systems are supplied with 50 feet Cat 3 of 6-wire, twisted pair
communication cable with RJ11 type connectors. Caution must be taken when connecting
two lengths of communication cable (splicing) to ensure uniform wire color before and after
splice. An RJ11 Modular 6 wire STRAIGHT THROUGH type coupler is the ONLY coupler
approved for splicing Wine Guardian twisted pair communication cable.
