GENERAL INFORMATION
Cooling System
This Bard cooling system is composed of MULTI-TEC, FUSION-TEC WR Series and/or MEGA-TEC wall-mounted
air conditioners matched with an LC6000 controller or Bard th-Tune stand-alone controller (th-Tune can only be
used with MULTI-TEC units). If only one wall-mounted air conditioner is being used, it can be matched with either
the LC6000 or a th-Tune stand-alone controller (if applicable). If more than one wall-mount unit is installed, the
LC6000 controller must be matched with the air conditioning units. The wall-mount units are specifically engineered
for equipment cooling applications.
NOTE: The LC6000 controller and MULTI-TEC, FUSION-TEC WR Series and MEGA-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, FUSION-TEC WR Series or MEGA-TEC wall-mount units. They are a
complete system, and must be used together.

electricity shorts to electronic controls.
Bard recommends the use of
LC6000 Controller
The LC6000 controller is part of this air conditioning
system. It is used to control up to 14 wall-mount air
conditioners from one controller. The microprocessor
control provides an easy-to-read interface with
large LCD graphical display. It provides control for
redundancy for the structure and equal wear on all
units.
Conduit is recommended for all wiring. Route
communication wiring and power supply wiring in their
own separate conduits.
The LC6000 controller is not weatherproof and is
intended for use in a weathertight structure.
IMPORTANT: When connecting this product from a
remote location, ensure that the network
connection is secure and reliable.
Mounting the LC6000 Controller
The dimensions of the LC controller are 16" x 12" x 6".
Because the LC6000 controller utilizes a remote
temperature sensor as opposed to one located in the
controller box, the controller itself can be installed in
any indoor location that is suitable, preferably at eye
level. Four (4) mounting holes are provided for mounting
to the wall and holes for conduit connections are provided
in the base, sides and top of the controller.
The LC6000 controller includes four fused power
supply terminals in the terminal block. Before
connecting wires to the terminal block, confirm that the
fuse in each of the four fuse holders is in the proper
position (active) as shown in Figure 2.

The LC6000 controller is powered by 120, 208 or 240 volts from the shelter. Field-supplied supply wiring should
be minimum 16 gauge, maximum 14 gauge (see Figure 3). A reliable earth ground must be connected in addition
to any grounding from conduit. Grounding bolts and nuts are included with the controller for this purpose; a 2 hole
grounding lug must be field supplied. Install as shown in Figure 4. Failing to ground the controller box properly could
result in damage to the equipment.

One remote indoor temperature/humidity sensor and 35' of 18 gauge 5-conductor shielded cable is included with the
controller. This sensor must be installed for proper operation. Mount the temperature/humidity sensor in a location
least likely to be affected by open doors, rack-mounted fans, radiant heat sources, etc. Locating the sensor between
both return grilles is often the best location, but every installation is unique. Location height should be approximately
60" above the floor. The sensor should be installed on a 2" x 4" junction box to allow for control wire conduit. Use
shielded cable to connect to controller.

Page 12 of 37
Connect the communication wiring from the controller to the wall-mount units in the manner shown in Figures 10,
11 or 12. The daisy chain does not need to follow the addressing order. The communication wire should be 2-wire,
18 gauge shielded cable with drain. Any color can be used. Be sure to match "+" and "-" symbols on controller
terminal blocks to prewired unit control terminal block. Attach communication wire filters as shown in Figures 10,
11 or 12. Do not run communication wiring in same conduit as supply wiring.
Route communication wiring and
power supply wiring in their own separate conduits.
The wall-mount units may not look the same as those depicted in the figures but these directions apply to all
units connected to the LC6000-200 controller.

Demand
The system will compare the zone temperature
(determined by zone averaging selection) to the
zone cooling and heating setpoint. A demand will be
calculated to determine how many units are required.
For cooling, the zone temperature will be compared
to the cooling setpoint. The controller will calculate a
demand based on how far above the setpoint and how
long it has been above the setpoint. The demand value
(0-100%) will then be split and applied to free cooling
and cooling separately shown as two demands both
ranged 0-100% applied to all of the available cooling
methods for that zone. For example, if the demand is
at 50% and there are 10 available stages of cooling in
that zone, there would be 5 stages active (50% x 10
= 5). The system will prioritize free cooling stages over
compressor stages. Adding to the example, if 5 of the
10 stages for cooling are economizer, 5 units would
be running economizer and no compressors running.
The demand is calculated for the cooling application.
However, for display purposes, the demand is split
so that the user can see demand separately for free
cooling and compressor.
For heating, the zone temperature will be compared
to the heating setpoint. The controller will calculate a
demand based on how far below the setpoint and how
long it has been below the setpoint. The demand value
0-100% will the be applied to all of the available stages
of heating in that zone. For example, if the demand is
at 50% and there are 5 available stages of heating in
that zone, there would be 2 stages active (50% x 5 =
2.5 and a half of a stage cannot be turned on).
Humidity Control
The LC can be configured to control up to three
humidifiers (field supplied) with relay outputs and
up to 14 units equipped with dehumidification. The
indoor humidity level for each zone is compared to the
dehumidification setpoint and humidification setpoint
for each zone.
Dehumidification
The LC6000 controller will monitor the indoor relative
humidity of each zone and compare the value to
three setpoints for each zone. The three setpoints
will be described as dehumidification off, passive
dehumidification and active dehumidification. The
default value for these setpoints will be 60% RH, 70%
RH and 80% RH, respectively.
When the humidity level inside the shelter falls to the
dehumidification off setpoint, the system will stop
attempting to dehumidify the space.
When the humidity level rises to the passive
dehumidification setpoint, all units with economizers
will disable the use of economizers for cooling calls.
This will act as passive dehumidification by forcing the
use of compressor for space cooling. Availability for
passive dehumidification will be determined by model
number. All units with economizers will be considered.
When the humidity level rises to the active
dehumidification setpoint, the controller will activate
staged dehumidification. The controller will then
calculate a dehumidification demand based on how
far above the setpoint and how long the RH level
has been above the setpoint. The demand will then
utilize all of the units with active dehumidification
capabilities to reduce the indoor humidity level. The
units will be staged on based on the existing cooling
rotation for the units in the zone up to an optional
maximum number of units running value. Availability
for active dehumidification will be determined by
model number. Units with concurrent electric reheat
or mechanical dehumidification will be considered.
NOTE: Only one type of dehumidification unit will
be considered depending upon configuration of the
LC6000 controller. Unit capability is determined by the
model number.

TROUBLESHOOTING
8403-079 Remote Indoor Temperature/Humidity Sensor
Troubleshooting the temperature/humidity sensor is necessary if the temperature or humidity reading for a zone is
inaccurate. Always start sensor troubleshooting by verifying connections at the sensor board and at the LC6000
terminal blocks. Improper connection will cause inaccurate readings. Next, verify continuity at both ends of wires
running between the sensor and the LC6000. A severed or damaged wire will cause inaccurate readings. As a last
step, verify voltage and resistance at the sensor and the LC6000 terminal block per the Tables 3 and 4. If the sensor
is found to be malfunctioning, replace the sensor.

NOTE:
Wire indexes are identified such that
even numbered index numbers are on
the lower wire entries of the terminal
block and odd numbered index
numbers are on the top wire entries.
Since terminal block 60 is a ground
block, terminal blocks 61 thru 72
shift while still maintaining the same
top and bottom configuration.
