The TB7300 PI thermostat family is specifically designed for fan coil control in commercial buildings. These communicating thermostats are available in BACnet® MS/TP and ZigBee® wireless mesh protocols and can be easily integrated into a WEBs-AX building automation system based on the NiagaraAX® platform. Select from a range of 24 Vac models that provide control of 2 or 4 pipe fan-coil units with on/off, floating or analog control and manual or automatic heat/cool changeover. Additionally, 3-speed fan control and auxiliary on/off heat control with relay (not included) are also supported. All models include a remote sensor input, two digital inputs, universal input, and an auxiliary output.


  • Available in BACnet MS/TP and ZigBee wireless protocols
  • Backlit LCD display with dedicated function menu keys for simple operation
  • Internal humidity sensing for increased occupant comfort through dehumidification on some models
  • Fully integrated advanced occupancy functionality with a PIR cover provides energy savings opportunity on select models; all other models are PIR ready and can have an optional occupancy sensor cover added
  • Configurable sequences of operation
  • Configurable fan button allows thermostat to meet more applications with a single model
  • Password protection to minimize parameter tampering
  • Six levels of keypad lockout to limit access to change user parameters
  • 3-speed fan control
  • Auto Fan speed mode increases occupant comfort in cooling mode by reducing humidity and reduces fan noise
  • Available for 24 Vac on/off, floating or analog control meets advanced applications requirements
  • Three inputs for monitoring and other advanced functions
  • SPST auxiliary output that can be used for lighting or auxiliary reheat
  • All wiring connections are made to removable terminal blocks simplifying installation.
