Preliminary Start Up; Running In Stand Alone (Orphan) Mode; Figure 11 Cooling And Heating Setpoints - Bard MULTI-TEC W24AAPA Installation Instructions Manual

Running in Stand Alone (Orphan) Mode

With the AC breakers turned on, each MULTI-TEC
wall-mount unit has the capability to run without
the LC6000 controller or th-TUNE connected—this
feature is called stand alone or 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 stand-
alone mode, the wall unit 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.
The wall-mount unit can be turned on and off with
the TEC-EYE hand-held diagnostic tool. When ON is
chosen, the wall-mount unit will heat or cool. When set
to OFF using the TEC-EYE, the wall-mount unit will not
heat, cool or ventilate.
To turn the unit on or off with TEC-EYE:
1. Connect the TEC-EYE diagnostic tool to the control
board located in the unit.
2. Press MENU key to go to the Main Menu screen.
3. Press UP or DOWN keys and ENTER key to enter
USER password 2000.
4. Press UP or DOWN keys to scroll to On/Off; press
ENTER key.
5. Press UP or DOWN keys to change value from On
to Off or from Off to On.
6. Press ESCAPE key several times to return to Main
Menu screen.
To verify or change the wall-mount unit cooling and
heating setpoints in stand alone mode:
1. Connect the TEC-EYE diagnostic tool to the control
board located in the unit.
2. From the Status screen, press UP or DOWN key
until Quick Menu displays Setpoints (SET) icon.
Press ENTER key.
3. Press ENTER key to scroll to the selected choice
(see Figure 11).
4. Press UP or DOWN key on desired value until value
displays correctly.
5. Press ENTER key to save and scroll to next
parameter.
6. Press ESCAPE key until Main Menu screen is
displayed.

PRELIMINARY START UP

FIGURE 11
Cooling and Heating Setpoints
During installation, the ability to run in stand alone
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
MULTI-TEC wall-mount units is installed, orphan mode
can be enabled early in the installation—keeping the
climate inside the shelter stable and the installers
comfortable while the remainder of the older equipment
is removed and the remaining Bard MULTI-TEC wall-
mount units and LC6000 controller are installed.
To ensure units will go into stand alone mode,
disconnect the plug marked R-T-/R+T+/GND on the
control board located in the wall-mount unit. Be sure
to reconnect the plug before operating the wall-mount
unit as part of the Bard Free Cooling Unit System.
Additionally, should any or all of the MULTI-TEC 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.
NOTE: Screenshots shown in this manual reflect
default settings (when applicable).
