TB & TM Series Thermostats
TB-TM

The Carrier TB and TM Series Thermostats available in BACnet (TB series) or MODBUS (TM series) communication protocols come with a variety of options and features for a wide range of HVAC applications. The TB and TM Series thermostats offer either zone/room/building control or building management system (BMS) level control. Utilizing Carrier’s powerful i-Vu® building automation system’s platform, the user can be sure that each space has precision temperature control.

  • Built-in temperature, humidity, and/or motion sensing for optimal control
  • Intuitive push-button interface with a clear LCD display
  • BACnet or MODBUS communication protocol capable (depending on model) for flexible system integration
  • Configurable inputs and outputs to support a variety of HVAC applications 
  • Real-time clock maintains accurate time for up to 7 days during power outages
  • Choice of 24VAC or 110-220V power supply for installation flexibility*

*Depending on thermostat model

  • Fan (FCUs): Enhance occupant comfort by providing individual control over fan speed and temperature
  • Rooftop Units (RTUs): Optimize RTU operation for energy efficiency through precise temperature and airflow control
  • Heat Pumps: Maximize heat pump performance and efficiency with integrated control of heating and cooling modes
  • Variable Frequency Drives (VFDs): Seamlessly integrate with VFDs to fine-tune motor speeds and optimize energy consumption
