APPENDIX E — UPC OPEN CONTROLLER (cont)
Configuring the UPC Open Controller's Properties
The UPC Open device and ComfortLink controls must be set to
the same CCN Address (Element) number and CCN Bus num-
ber. The factory default settings for CCN Element and CCN
Bus number are 1 and 0 respectively.
If modifications to the default Element and Bus number are re-
quired, both the ComfortLink and UPC Open configurations
must be changed.
The following configurations are used to set the CCN Address
and Bus number in the ComfortLink controls. These configura-
tions can be changed using the scrolling marquee display or ac-
cessory Navigator handheld device.
Configuration→CCN→CCN.A (CCN Address)
Configuration→CCN→CCN.B (CCN Bus Number)
The following configurations are used to set the CCN Address and
Bus Number in the UPC Open controller. These configurations
can be changed using the accessory BACview

display.
Navigation: BACview→CCN
Home: Element Comm Stat
Element: 1
Bus: 0
Troubleshooting
If there are problems wiring or addressing the UPC Open con-
troller, contact Carrier Technical Support.
COMMUNICATION LEDS
The LEDs indicate if the controller is communicating with the
devices on the network. See Tables J and K. The LEDs should
reflect communication traffic based on the baud rate set. The
higher the baud rate the more solid the LEDs become. See
Fig. H for location of LEDs on UPC Open module.
REPLACING THE UPC OPEN BATTERY
The UPC Open controller's 10-year lithium CR2032 battery
provides a minimum of 10,000 hours of data retention during
power outages.
Remove the battery from the controller, making note of the bat-
tery's polarity. Insert the new battery, matching the battery's po-
larity with the polarity indicated on the UPC Open controller.
Table J — LED Status Indicators
Table K — Run and Error LEDs Controller and Network Status Indication
IMPORTANT: Power must be ON to the UPC Open
when replacing the battery, or the date, time, and trend
data will be lost.
LED STATUS
Power
Lights when power is being supplied to the controller. The UPC Open controller is protected by internal solid-state polyswitches on
the incoming power and network connections. These polyswitches are not replaceable and will reset themselves if the condition
that caused the fault returns to normal.
Rx Lights when the controller receives data from the network segment; there is an Rx LED for Ports 1 and 2.
Tx Lights when the controller transmits data to the network segment; there is a Tx LED for Ports 1 and 2.
Run Lights based on controller status. See Table K.
Error Lights based on controller status. See Table K.
