Standard NPT Ports: 1/2" female NPT threads allow for seamless integration into existing HVACR piping systems

allowing for remote sensing when the radiator is concealed behind cabinetry or architectural covers that would otherwise restrict airflow to a standard sensing head

While this unit features dual 1/4" barb connections for differential sensing

Technicians often look for furnace short-cycling

Key Benefits for Technicians Fixed Thermal Calibration: Precise 170°F open and 150°F close setpoints prevent nuisance tripping while ensuring robust heat exchanger protection
