owner. A USB jump drive can be used to back up the unit's con-
figurations. Refer to the USB Operation section for details.

Initial Startup

Initial Startup refers to the first time this particular unit has a
startup performed. The SystemVu controller will continually
display the Initial Startup prompt until it is completed. To com-
plete the initial startup you must complete the Quick Setup,
Network Setup, and the System Auto Test.
QUICK SETUP
This a list of common adjusted configurations set during start-
up. These are common accessories and control means. See the
list in Table 3. After setting these per the specific unit, set the
QUICK SET CHKLIST point to done.

NETWORK SETUP
This is a shortcut to the Network Settings submenu. In this sub-
menu are the specific network settings required to get the net-
work piece up and running. After setting these per the specific
unit, set the NETWORK CHKLIST point to done.
SYSTEM AUTO TEST
Turning this to Start will run enable test mode and execute the
System Auto Test. After the auto test has completed, set this to
done.

Thermostat Control

Wire accessory thermostat to the corresponding R, Y1, Y2, Y3,
W1, W2, and G terminals on the Main Base board.
The Unit Control Type configuration, (UNIT CONTROL
TYPE) default value is for thermostat (0) so there is no need to
configure this item.
The Thermostat Hardware Type, (THERMOSTAT TYPE) se-
lects the unit response to the thermostat inputs above.
NOTE: May not be compatible with heat anticipator thermostats.

Space Temperature Sensor Control - Direct
Wired (T-55 or T-56 or T-59)
Wire accessory space temperature sensor(s) to the T-55 termi-
nals on the field connection terminal board located at the unit
control box. Refer to Space Mounted Sensors section (page 71)
for additional information.
The Unit Control Type configuration, (UNIT CONTROL
TYPE) must be set to Space Sensor (1).

Space Humidistat Control

For units with the factory-installed Humidi-MiZer
tion, the humidistat input is provided with quick connects. The
Space Humidity Switch configuration, SETTINGS  UNIT
CONFIGURATIONS  SWITCH INPUTS CONFIGS 
HUMSTAT CHANNEL identifies the normally open or nor-
mally closed status of this input at HIGH humidity.

Relative Humidity Sensor Control

For units with the factory-installed Humidi-MiZer system op-
tion, the humidity sensor input is provided with quick connects.
The sensor can be used instead of a humidistat. The RH Sensor
configuration, SETTINGS  UNIT CONFIGURATIONS 
ANALOG INPUTS CONFIGS  SPRH SENSOR CHAN-
NEL, identifies the point on the MBB (Main Base board) or the
IOB (Input Output board) the sensor was wired into.

CCN Communication

First configure the building protocol SETTINGS  NET-
WORK SETTINGS  BAS PROTOCOL to CCN (default is 0
= NONE). Configure the following under the CCN menu
(SETTINGS  NETWORK SETTINGS  CCN).
CCN ELEMENT # — Default is 1
BUS NUMBER — Default is 0
CCN BAUDRATE — Default is 2 = 38400

CCN Linkage Control

The CCN communication must be properly configured for the
48/50LC units and all other devices. Linkage configuration is
automatically done by the supervisory CCN Linkage device.
The unit control type configuration, (UNIT CONTROL TYPE)
must be set to space sensor (1).
Installation of an accessory supply air temperature (SAT) sen-
sor on the fan deck near the corner post is recommended for
Linkage applications. The SAT heat mode sensing configura-
tion (SAT DURING HEAT?) will be enabled at the factory.
System Pilot™ – Communication Space Sensor
Install the System Pilot device and connect the CCN communica-
tion bus from it to the unit's CCN connection on TB4 - BAS con-
nector of the Main Base Board (MBB). Configure the unit's CCN
communication element number, bus number, and baud rate. Re-
fer to the System Pilot's installation instructions for configuring it
to be used as a space temperature and attaching it to a unit.
SystemVu™ Controller
The SystemVu controller will support the use of i-Vu
ZS sensors and either Equipment Touch™ or System Touch™
when the Network Protocol is BACnet. SETTINGS

Accessories

Below are quick configuration settings for field-installed ac-
cessories. When factory-installed as options, the points will al-
ready be configured. See the Space Mounted Sensors section
(page 71), third party control, control connection tables, and
CCN or Display parameter tables for any accessories not men-
tioned below and refer to installation manual of the accessory.
