Device Addressing

Each UCM must have a unique address that is set using a DIP switch on
the scroll chiller. For CGA/CGWs, the location of the address DIP
switches is shown in Figure 47 on page 100. For address DIP switch set-
tings for CGA/CGWs, refer to Table 17 on page 103.
For CGAFs, addresses are set from the front panel. Refer to the CGAF
installation, operation, and maintenance manual for details.
