Communication Interfaces
BACnet® Building Automation Control
Network
The BACnet® control network for Symbio™ 800 expands
communications from the unit UCM network to the
Tracer® Ensemble™ or Tracer SC+ building automation
system or third party building automation system.
Utilizing BACnet, the BAS allows external setpoint and
configuration adjustment and monitoring of status and
diagnostics. The Symbio™ 800 utilizes the BACnet defined
TP protocol as defined in ASHRAE standard 135-2004. This
controller works in standalone mode, with Tracer®
Ensemble™, Tracer SC+ or when connected to a third
party building automation system that supports BACnet.
Modbus Automation Control Network
Allows the user to easily interface with Modbus™ RTU
communication protocol via a single twisted pair wiring
from the Symbio™ 800 controller to a factory installed
device.
LonTalk® Building Automation System
The LonTalk® communication protocol for the Symbio™
800 controller expands communications from the unit
UCM network to a Tracer® Ensemble™ building
automation system or third party building automation
system. Utilizing LonTalk®, the BAS allows external
setpoint and configuration adjustment and monitoring of
status and diagnostics. The Symbio™ 800 utilizes an FTT-
10A free topology transceiver, which supports non-
polarity sensitive, free topology wiring—which in turn
allows the system installer to utilize star, bus, and loop
architectures. This controller works in standalone mode,
peer-to-peer with one or more other units, or when
connected to a Tracer® Ensemble™, Tracer SC+, or a third
party building automation system that supports
LonTalk®.
