WARNING
Electrical shock hazard.
Disconnect VAC and VDC power supplies
before servicing.
Failure to do so could result in electric shock
or death.
LV1000 Controller
The LV1000 controller is part of the Free Cooling
Unit system by Bard. It is used to control up to four
(4) 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. The LV1000 controller is configured for
first on/next on sequence.
Conduit is recommended for all wiring. Route
communication wiring and power supply wiring in their
own separate conduits.
The LV1000 controller is not weatherproof and is
intended for use in weathertight structure.
1. Mounting the LV1000 Controller
Because the LV1000 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 connection are provided
in both the base, sides and top of the controller.
The LV1000 controller includes a fused power supply
terminal in the terminal block. Before connecting wires
to the terminal block, confirm that the fuse in the fuse
holder is in the proper position (active) as shown in
Figure 1.2.

2. Installing Remote Indoor Temperature/Humidity Sensor(s)
One remote indoor temperature/humidity sensor and 35' of 18 gauge 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. 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 (see Figure
1.3). Use shielded cable to connect to controller.

2. Connect the other end of the shielded cable to the sensor
terminals. Be sure wires are connected to proper terminals
as shown in table above. Sensor jumpers need to be
positioned for 0-1 V. With sensor oriented as shown in
image to right, move both jumpers to left position (DP1 and
DP2 set to OFF).
This applies to all temperature/humidity sensors connected
to the LV controller.
Sensor is best mounted on a junction box, and it is
recommended that the cable be in conduit.

For proper operation, the remote indoor temperature/humidity sensor must be configured properly with the
controller. If only the single remote indoor temperature/humidity sensor supplied with the controller is installed,
the configuration setting is "0". This is the default setting. Up to two additional temperature and humidity sensors
can be purchased and installed. Alternately, temperature-only sensors can be purchased and installed instead of
the combination sensors. For information on remote indoor sensor configuration, see page 21.
Use shielded cable to
connect additional sensors to controller.
FIGURE 1.4
Additional Remote Temperature and Temperature/Humidity Sensor Installation
Up to two additional temperature/humidity sensors may be added. Be sure the sensors are connected to the proper

The LV1000 controller is powered by -48VDC from the shelter. A field-supplied 5 amp DC circuit breaker is required.
Field-supplied supply wiring should be minimum 16 gauge, maximum 14 gauge (see Figure 1.11). A reliable
earth ground must be connected in addition to any grounding from conduit. Grounding posts are included with the
controller for this purpose; install as shown in Figure 1.12. Failing to ground the controller box properly could result
in damage to the equipment.
FIGURE 1.11
LV1000-100 Controller Supply Wiring
The controller requires a separate -48VDC power supply, an additional 5-amp DC breaker (field supplied) and minimum 16
gauge supply wire.
-48VDC termination at controller: Bring the -48VDC power supply wires through conduit to the controller box. Land the
positive (+) 48VDC wire to terminal #1 and the negative (-) 48VDC wire to terminal #2.
NOTE: If the DC wiring is not terminated correctly on the specific polarity-indicated terminals of the
block, the controller will not activate and will not function. Verify polarity of connections and wait to
initialize controller until "system start up."

SYSTEM START-UP
Before the Bard Free Cooling Unit system can be set up
for operation, each wall-mount unit must have already
been installed, given a unique address and had a run
test performed (see FUSION-TEC manual 2100-670).
After those procedures have been completed with each
unit, the system start-up can proceed.
The LV1000 controller will be used to set up the Bard
Free Cooling Unit system.
LV1000 Controller
The microprocessor control used in the FUSIONTEC wall-mount air conditioners allows for complete
control and monitoring through the use of the LV1000
controller.
The menu driven interface provides users the ability
to scroll through two menu levels: Quick Menu and
Main Menu. The menus permit the user to easily view,
control and configure the wall-mount unit system.
The controller is completely programmed at the factory;
the default setpoints and their ranges are easily
viewed and adjusted from the controller display. The
program and operating parameters are permanently
stored on FLASH-MEMORY in case of power failure.
The controller is designed to manage temperature and
humidity levels to a user-defined setpoint via control
output signals to the wall-mount air conditioning
system.
The TEC-EYETM diagnostic tool is shipped inside the
controller. See FUSION-TEC manual 2100-670 for
more information on using the TEC-EYETM.

CONTROL OPERATION
Temperature Control
Control Value Averaging
The system requires one temperature and humidity
sensor (included with LV) to operate. It allows a total
of three temperatures and three humidity sensors to
be connected to the LV for better representation of
what is happening in the shelter. When more than one
sensor is used, the value is averaged and then used for
temperature control operations and humidity control
operations.
Comfort Mode
The LV has a feature that allows a temporary override
of the temperature control settings. When “comfort
mode” is activated, the system will control to 72°F.
The system will stay in this mode for 60 minutes
and is intended to provide a more comfortable space
for a technician during a service call or scheduled
maintenance.
Emergency Mode
When the high temperature alarm 2 or the hydrogen
input indicate an alarm, the system will enter
emergency mode. The LV will communicate to each
wall unit that emergency mode is active. The wall units
will the override the damper position to 100% open
and turn the blower on. These two items will stay in
this state until both the high temperature alarm 2 and
the hydrogen detector are no longer in an alarm state.
Cooling
When the wall units are connected to the LV, the
economizer and compressor are commanded off and
on by the LV. This allows the supervisory controller to
consider the most effective and efficient order to bring
cooling functions on using all of the available equipment
installed on the shelter. At the same time the LV will be
able match the load requirements of the shelter.

FIGURE 2.6
Adjusting Setpoints
The LV monitors the space temperature and compares
the value to the space cooling setpoint. The system will
compare how far above or below the space temperature
is when compared to the cooling setpoint. The LV will
also consider how long the shelter temperature has
been above or below the setpoint. Using these two
considerations, the controller will generate a cooling
demand. The cooling demand is a value between 0 and
100%. 0% represents no cooling demand and 100%
representing full cooling demand.
The system will consider all of the available cooling
stages and distribute the number of stages across
the cooling demand range. As the demand rises, the
system will stage on equipment every 2 minutes. As the
demand lowers, the system will stage off equipment
every 2 minutes.
The system will stage the equipment on in the order
shown in Table 2.2.
The system is also capable of rotating the order
in which the units are brought on. This is done to
distribute the equipment run time to each unit. This
prevents one unit from providing all of the cooling for
the shelter and shorting the lifespan of the wall unit.
The system is set to switch the unit staging order
every 7 days from the factory. This timeframe can be
changed if desired by the end user. In addition to the
time-based auto rotation, the system can be manually
rotated on site for troubleshooting purposes.
To view the lead unit, turn the rotation on/off, change
the number of days between rotations or manually
rotate the units:
1. Press MENU key to go to the Main Menu screen.
2. Press UP or DOWN keys and ENTER key to enter
USER password 2000.
3. Press UP or DOWN keys to scroll to Sys Config;
press ENTER key.
4. Press UP or DOWN keys to scroll to Unit Rotation
(A2); press ENTER key.

Adjusting Setpoints
Dehumidification
The system will take several actions to limit the indoor
humidity level. At 70% RH, the economizer will be
disabled to prevent outdoor air from being used to cool
the shelter which may have a high moisture content.
This mode will remain active until the shelter humidity
level is below 60% RH. The system will switch from
high sensible to standard mode when the indoor
humidity is above 75% RH which will slow the blower
down to remove more moisture. This mode will remain
active until the shelter humidity level is below 65%.
If the shelter reaches 80% RH, the system will switch
the units into dehumidification mode. This mode will
cool the shelter down to the heating setpoint and
the compressor will turn off. Then the heat strip will
activate and heat it back up to the cooling setpoint,
then turn off. This will continue until the indoor
humidity level is below 70% RH.
Fan Control
The LV has the option to change the continuous blower
setting of the units connected to it. The options are All,
Lead and None. If the option is set to All, then all of
the units connected will run the blower continuously.
If the option is set to Lead, only the unit in the lead
position will run the blower continuously. If the option
is set to None, then none of the units will run the
blower continuously. When continuous blower doesn’t
apply to a unit, it will cycle the blower based on
heating or cooling calls.
Hour Counting
The LV will keep track of the heating and cooling
method run times for last hour. In addition to how long
an item was on, it will also track how many times a
method started.
