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 FUSION-
TEC 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.
