BACNET FIXED FUNCTION THERMOSTAT
TECHNICAL REFERENCE MANUAL
PRODUCT DESCRIPTION
Honeywell's BACnet® Fixed Function Thermostat, BACnet FF, is a configurable device with 19 pre-loaded applications.
The thermostat is a communicating, intelligent sensor-controller combination with built-in temperature and humidity
sensors used to control applications such as roof top units, fan-coil units and heat pumps. The thermostat communicates
over an MS/TP LAN so it operates as a fully-functioning BACnet controller and easily integrates with the building
automation system. The two available models are TB3026B and TB3026B-W, which includes a wireless sensor option.
