BOSS AND BOSS MINI SUPERVISION System of connectivity, monitoring and remote management Protocols and connectivity For the first time ever on a CAREL supervisor, BOSS its Wi-Fi network, using the WiFi-Modbus gateways. introduces the BACnet protocol, the leading protocol in HVAC Nonetheless, when a wired connection is available, this is the supervision applications. preferred option due to its reliability. ■ Integration of third party devices This new feature significantly increases the possibility to integrate third party devices.The BACnet Master protocol is available in both MS/TP (RS485) and TCP/IP modes, and together with the Modbus RS485 and Modbus TCP/IP protocols, these too available on BOSS, offers the possibility to interact with the widest range of devices in the HVAC/R sector. ■ BMS integration In addition to Master mode, the BACnet protocol is also available on BOSS in TCP/IP Slave mode, allowing BOSS to be integrated into a higher-level BMS, sharing the values of interest for overall building management (e.g. unit status, alarm status, ON/OFF controls,...) ■ Wireless field connectivity If Modbus RTU devices cannot be connected directly to the BOSS / BOSS-mini RS485 network due to installation BMS constraints, these can be integrated into the boss system via System optimisation functions (optional) ■ KPI ■ Energy ■ Floating suction ■Dew point Performance index.
