Conventions Used in This Manual
The following conventions for discussing configuration points
for the local display (SystemVu controller or Navigator™ ac-
cessory) will be used in this manual.
Menu paths will be written with the main menu name first,
then any menus or submenus, each separated by an arrow sym-
bol () and will also be shown in bold and italics. As an ex-
ample, the General submenu, which is located in the Setting
main menu under Unit Configuration menu, would be written
as SETTINGSUNIT CONFIGURATIONSGENERAL.
This path name will show the user how to navigate through the
local display to reach the desired menu. The user scrolls
through the Menus using the up and down keys. The arrow
symbol in the path name represents pressing ENTER to move
into the next level of the menu structure.
Point names are referenced in parentheses and in bold and ital-
ics as would be shown on the local display.
CCN point names are also referenced for users configuring the
unit with CCN software instead of the local display. See Ap-
pendix A at the end of this manual.
BASIC CONTROL USAGE
SystemVu Control (factory-installed option)
The SystemVu control is a comprehensive unit-management
system. The control system is easy to access, configure, diag-
nose and troubleshoot.
The SystemVu control system is fully communicating and ca-
ble-ready for connection to the Carrier Comfort Network
®
(CCN), Carrier i-Vu
®
, and Third Party BACnet

building man-
agement systems. The control provides high-speed communi-
cations for remote monitoring via the Internet. Multiple units
can be linked together (and to other Direct Digital Control
(DDC) equipped units) using a 3-wire communication bus.
The SystemVu control system is easy to access through the use
of a integrated display module. A computer is not required for
start-up. Access to control menus is simplified by the ability to
quickly select from 7 main menu items. An expanded readout
provides detailed explanations of control information. Only six
buttons are required to maneuver through the entire controls
menu. The display readout is designed to be visible even in
bright sunlight.
SystemVu Interface
This integrated device is the keypad interface used to access
the control information, read sensor values, and test the unit.
The interface is located in the main control box and is standard
on all units. The interface is a 6-key, 4x30 character, LCD (liq-
uid-crystal display) display module. The interface also contains
Status LEDs. (See Fig. 2.) The interface is easy to operate us-
ing 6 buttons and the main menu structures shown in Fig. 3.
Through the SystemVu interface, the user can access all of the
inputs and outputs to check on their values and status, config-
ure operating parameters, and evaluate the current decision sta-
tus for operating modes. The control also includes an alarm
history which can be accessed from the display. The user can
access a built-in test routine that can be used at start-up com-
missioning and troubleshooting.
