Description
The Trane CNT1846 Freeze Stat is a temperature safety control that monitors low-limit air conditions to prevent coil freezing in HVAC systems. It activates at 44°F and resets at 36°F, using fixed setpoints to interrupt operation when temperatures drop to unsafe levels. This is installed near the evaporator or air coil, where it senses cold air conditions during operation. Its role is to shut down the system before ice formation occurs, helping protect coils and maintain reliable equipment performance.
