Exporting 7 Day Logs

See latest version of Supplemental Instructions manual
7960-816 for information on exporting 7 day I/O logs.
Orphan Mode
FUSION-TEC WR Series wall-mount units have the
capability to run without the LC6000 controller
attached—this feature is called orphan mode. This
keeps the shelter between 60°F and 77°F (factory
default settings) by the use of the factory-installed
return air sensor in each wall-mount unit. In orphan
mode, no auxiliary temperature measurement devices
are required for operation. The wall-mount unit
automatically uses a continuous blower setting to
circulate room air into the return air inlet and uses
the return air temperature sensor to control room
temperature.
To change default setpoints, refer to Setpoints on page 8.
During installation, the ability to run in orphan mode
allows deactivation of one of the existing, older wall-
mount units, while keeping the shelter cool with the
other unit still operating. Once the first of the Bard
wall-mount units is installed and powered on, it will
operate in orphan mode—keeping the climate inside
the shelter stable and the installers comfortable while
the remainder of the older equipment is removed and
the remaining Bard wall-mount units and LC6000
controller are installed.
Additionally, should any or all of the FUSION-TEC WR
Series wall-mount units lose communication with the
LC6000 controller (such as during maintenance), they
will continue to serve the shelter's needs until a repair
can be made.

Zone

When paired with a supervisory controller that uses
zones to control groups of wall units, this unit uses the
zone setting to relay to the supervisory controller what
zone it is set to operate in.

5. Press ENTER key to scroll to Zone (see Figure 18).
6. Press UP or DOWN keys to change to the desired
value.
7. Press ENTER key to save value.

Temperature/Humidity Control Components

Return Air Temperature Sensor

The unit is equipped with a return air temperature
sensor to monitor the space temperature when the unit
is in orphan mode. The return air sensor is located
in the upper part of the return opening in such a way
that it is exposed to the entering airstream. An alarm
signal will be sent to the LC controller if the return air
temperature sensor is disconnected. The temperature is
measured with a 10k ohm NTC thermistor.
This sensor can be verified and adjusted by:
1. Press MENU key to go to the Main Menu screen.
2. Press UP or DOWN keys and ENTER key to enter
TECHNICIAN password 1313.
3. Press UP or DOWN keys to scroll to I/O Config;
press ENTER key.
4. Press UP or DOWN keys to scroll to Return Air
Sensor C4.
5. Verify the measurement displayed on screen is
accurate (see Figure 19).

offset value by pressing ENTER to scroll to Offset.
7. Press UP or DOWN keys to adjust the offset.
