INSTALLATION INSTRUCTIONS
APPLICATION
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.
