The Trane CNT0428 is a professional-grade SPST (Single Pole Single Throw) temperature control engineered for precision sensing in demanding HVACR applications. Operating within a 20°F to 80°F range, this mechanical thermostat provides reliable on/off logic for air handlers, heat pumps, and industrial cooling systems. This Trane replacement control comes integrated with a dedicated sensing well and capillary tube, ensuring optimal thermal conductivity and protection for the sensor in high-vibration or high-flow environments. As a veteran technician knows, maintaining refrigeration temperature regulation requires a component that can withstand ambient fluctuations while providing consistent switching. The Trane CNT0428 control is designed as a direct OEM HVAC part to restore system performance without the compatibility risks associated with universal aftermarket alternatives. Its durable construction focuses on long-term HVAC system reliability and straightforward mechanical integration into existing control circuits.

Item is Non Cancelable / Non Returnable

• Precise 20/80F Range: Ideal for low-to-mid range temperature monitoring and protection in HVACR units.
• SPST Switching: Provides a simplified, dependable on/off contact for control circuit continuity.
• Integrated Well and Capillary: Enhances sensor response time and protects the element from direct contact with fluid or airflow.
• OEM Compatibility: This is a genuine Trane component, ensuring exact physical and electrical fitment for specific model sequences.

Is the sensing well included with the CNT0428?
Yes, this model is supplied with a matched well and capillary assembly to ensure accurate temperature sensing right out of the box.

Can this be used for both heating and cooling applications?
The 20°F to 80°F range is versatile; however, as an SPST control, it is strictly for basic on/off switching based on temperature rise or fall within that specific window.

Does this unit require external power to operate the sensor?
No, this is a mechanical temperature control that utilizes a capillary system for switching, though your control circuit will provide the line or low voltage to be switched across the contacts.
