Carrier HH22CC050 Safety Stat

The Carrier HH22CC050 Safety Stat is a high-precision remote bulb safety stat engineered for critical temperature monitoring in commercial and industrial HVACR systems. As a genuine OEM Carrier replacement part, this limit control switch is designed to interface seamlessly with ComfortLink control boards and Carrier packaged units. It utilizes an accurate remote sensing bulb to monitor ambient or discharge air temperatures, ensuring the system operates within safe thermal parameters and preventing compressor or coil damage. Built for field reliability, the HH22CC050 provides a robust mechanical fallback for electronic controls, maintaining system integrity even during sensor drift or communication failures. When replacing a fixed-limit safety thermostat, technicians rely on this component for its proven calibration stability and direct compatibility with Carrier heating and cooling hardware. Proper installation of this commercial HVAC safety control ensures compliance with safety protocols and protects expensive downstream components from extreme temperature excursions.

• Precise Thermal Feedback: The remote bulb sensor provides accurate temperature detection far from the mounting point, ideal for duct or coil monitoring.
• OEM Compatibility: Guaranteed fit for specific Carrier packaged systems and split system condensers, reducing troubleshooting time.
• Enhanced System Protection: Acts as a critical safety limit switch to prevent overheating or freezing conditions that lead to equipment failure.
• Durable Construction: Engineered to withstand the vibration and temperature fluctuations common in demanding commercial HVACR environments.

What is the primary function of the HH22CC050 in a Carrier system?
This safety stat functions as a high-limit or low-limit cutout. It monitors temperatures via the remote bulb and breaks the control circuit if the setpoint is exceeded, protecting the system from mechanical stress.

Is the HH22CC050 compatible with non-Carrier equipment?
While it is an OEM Carrier part, it is technically a remote bulb thermostat that can be used in various HVACR control applications. However, for guaranteed performance and mounting alignment, it is best utilized within its specified Carrier unit series.

How do I test if the safety stat is functioning correctly?
Technicians should perform a continuity test across the terminals while the bulb is exposed to temperatures outside its differential. If the switch fails to open or close at the specified thermal threshold, the safety limit control requires replacement.
