Appendix F - Upc Open Controller - Carrier Weathermaster 48P030-100 Controls, Start-Up, Operation, Service, And Troubleshooting

The following section is used to configure the UPC Open control-
ler. The UPC Open controller is mounted in a separate enclosure
below the main control box.
NOTE: All factory provided UPCs are shipped with a local pro-
gram for English or SI units. If Metric interaction is desired a con-
trols Expert is required to rebuild the files for the UPC in Metric
and to change some specific variables to metric conversion. Make
sure to allow labor for this change.
To Address the UPC Open Controller
The user must give the UPC Open controller an address that is
unique on the BACnet 1 network. Perform the following procedure
to assign an address:
1. If the UPC Open controller is powered, pull the screw ter-
minal connector from the controller's power terminals
labeled Gnd and HOT. The controller reads the address
each time power is applied to it.
2. Using the rotary switches (see Fig. Z and AA), set the con-
troller's address. Set the Tens (10's) switch to the tens digit
of the address, and set the Ones (1's) switch to the ones
digit.

BACNET DEVICE INSTANCE ADDRESS
The UPC Open controller also has a BACnet Device Instance ad-
dress. This Device Instance MUST be unique for the complete
BACnet system in which the UPC Open controller is installed.
The Device Instance is auto generated by default and is derived by
adding the MAC address to the end of the Network Number. The
Network Number of a new UPC Open controller is 16101, but it
can be changed using i-Vu ®
20 will result in a Device Instance of 16101 + 20 which would be
a Device Instance of 1610120.
