Theory of operation
The display is available with the Applied Smart
Equipment type controller. It connects directly to
the built-in RS-485 port (SA or FC bus) on the main
control board (Figure 11), allowing straightforward
access to monitor and change all of the equipment
parameters.
Offering many-to-one, multi-client connectivity, the
MAP Gateway tool (Version 5.0 and above) is synced
with the display that gives user access to any Smart
Equipment device that is on a common BACnet (MS/
TP) field bus.
The display is operated through the built-in menu
system and MAP Gateway tool to provide access
to the real-time data and parameters stored in the
Applied Smart Equipment controller.
Note:
Throughout the remainder of this guide,
the Applied Smart Equipment main control
board is referred to as
controller
and the MAP
Gateway tool is referred to as
MAP
. The Applied
Smart Equipment controller is only provided on
the Premier line of rooftop units.
Display configurations
Each display unit is pre-loaded with firmware.
Different display unit configurations customize the
display as required for different unit applications.
When the user integrates the display with a
controller, the display unit matches one of its
stored configuration codes with the code defined
in the controller configuration. If it finds a match,
then the display uses the corresponding display
configuration. If it does not find a match, it uses the
default configuration.
The display unit matches the available
configurations only for the Applied Smart
Equipment controllers.
