General Information - Bard MULTI-TEC W24AAPA Installation Instructions Manual

Free Cooling Unit System
This Bard Free Cooling Unit System is composed of
MULTI-TEC wall-mounted air conditioners matched
with an LC6000 supervisory controller or Bard th-
TUNE stand-alone controller. If only one wall-mounted
air conditioner is being used, it can be matched with
either the LC6000 supervisory controller or a th-TUNE
stand-alone controller. If more than one wall mount is
installed, the LC6000 controller must be matched with
the air conditioning units. The wall-mount units are
specifically engineered for telecom/motor control center
rooms.
NOTE: The LC6000 supervisory controller and
MULTI-TEC wall-mount units are designed
specifically to work together. The controller
cannot run other brands of systems, nor can
other controllers run the MULTI-TEC wall-mount
units. They are a complete system, and must be
used together.
LC6000 Series
* One remote temperature/humidity sensor and 35' of 5-wire shielded cable are included with the LC6000
controller. If the site in which the LC6000 controller will be used has more than one zone (maximum three
zones per LC6000), additional remote temperature/humidity sensors (one sensor per zone) will need to be
purchased and installed in the additional zones. One additional temperature-only sensor (Bard P/N 8301-
058) may also be used in Zone 1 but will also need to be purchased separately. Temperature-only sensors
require field-supplied 2-wire shielded cable with drain.
Single Unit Operation
A th-TUNE stand-alone controller (Bard P/N 8403-088) can be used in place of the LC6000 controller when only
one MULTI-TEC wall-mount air conditioner is being installed. If using a th-TUNE stand-alone controller instead
of the LC6000 controller, the alarm logging and remote communication capabilities of the LC6000 controller
will not be available. See th-TUNE manual 2100-678 for information on installing and setting up a th-TUNE
stand-alone controller for single unit operation. A TEC-EYE hand-held diagnostic tool is required to program the
wall-mount unit for th-TUNE stand-alone controller operation. The th-TUNE stand-alone controller and TEC-EYE
diagnostic tool are available as a kit (Bard P/N 8620-264).
