BARD LINK CONTROLLER USER
TM
INTERFACE
The microprocessor control used in these wall mount
air conditioners allows for complete control and
monitoring through the use of the Bard Link
100 controller. These controllers utilize the latest in
state-of-the-art technology including a large, easy-to-
read backlit LCD graphic display.
The menu driven interface provides users the ability
to scroll through three menu levels: Info, Control and
Service. The menus permit the user to easily view,
control and configure the unit.
The controller is completely programmed at the factory;
therefore, most applications will require no field set-up.
However, 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
levels to a user-defined setpoint via control output
signals to the wall-mount air conditioning system.
WEB CARD COMMUNICATION BOARD
A web card communications board allows remote
access, via Ethernet, to all functions of the controller
system. This is the same as if one was in the building
where the controller system is physically installed.
