DIP switches select BACnet MS/TP (the default), BACnet ARC156, Modbus or N2, and a LonWorks option card is available. The device instance is built from Carrier's vendor ID (16) and the rotary address. Points cover setpoints, space and water temperatures, fan and compressor status, waterside economizer, alarms and the 'system' points a BAS writes in place of local sensors.",
