SYSTEMVU CONTROL SYSTEM

The SystemVu™ control is a comprehensive unit-management
system. The control system is easy to access, configure, diagnose
and troubleshoot.
The SystemVu control system is fully communicating and cable-
ready for connection to the Carrier Comfort Network
Carrier i-Vu ® , and Third Party BACnet
systems. The control provides high-speed communications for re-
mote monitoring via the Internet. Multiple units can be linked to-
gether (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 (see Fig. 51).

SystemVu Interface

This integrated device is the keypad interface used to access the
control information, read sensor values, and test the unit. The in-
terface is located in the main control box.

Fig. 51 — SystemVu Control
Through the SystemVu interface, the user can access all of the
inputs and outputs to check on their values and status, configure
operating parameters, and evaluate the current decision status 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 commissioning
and troubleshooting.

Air Temperature Sensors

The SystemVu controller uses thermistors to sense temperatures
used to control operation of the unit. Air temperatures are mea-
sured with 10k thermistors. This includes supply-air temperature
(SAT), outdoor-air temperature (OAT) and return-air temperature
(RAT) sensors. See Fig. 52 for location of these sensors.
