Why This Product Matters Now
The shift to low‑GWP refrigerants is accelerating across residential and commercial HVAC. These mildly flammable refrigerants require reliable monitoring and fast mitigation responses built directly into air‑handling equipment. The ICM‑UA2L‑24C‑DUAL is engineered specifically for this role, providing contractors, OEMs, and facility managers with a state‑of‑the‑art controller that integrates seamlessly into new or retrofit applications.
Key Features & Capabilities
- Rapid‑Response Safety Mitigation – The ICM‑UA2L‑24C‑DUAL provides fast compressor lockout and automatic system fan activation when an A2L refrigerant leak is detected—helping to dilute leaked refrigerant and shut down high‑risk components immediately.
- Dual Modbus Sensor Ports – Designed for flexible installation, the board supports two Modbus‑connected refrigerant sensors, allowing coverage of multiple leak‑risk zones (such as coil area + return plenum).
- Expanded Alarm & Control Output Options
- Fault Monitoring & LED Diagnostics – Built‑in fault status indicators and power LEDs provide technicians with quick, clear system information—simplifying troubleshooting and service‑time diagnostics.
- Supports Modern Refrigerants & Regulatory Requirements – Engineered to meet industry expectations for A2L‑rated systems, the UA2L‑24C‑DUAL is compatible with modern refrigerants like R‑32 and R‑454B, which are growing rapidly in new HVAC equipment due to their significantly lower environmental impact.

- Designed for Commercial & Industrial Duty – Its rugged design supports multiple sensors, flexible alarm configurations, and operation in demanding HVAC environments—important for large facilities transitioning to A2L refrigerants. [amazon.com]
The board offers:
- Dry contact CC output
- Fan output (N.C.)
- Alarm output (N.O.)
- Optional inverse‑logic alarm contact for integration with system controllers or building management systems (BMS).
These features allow full customization of mitigation logic depending on system design.
Applications
The ICM‑UA2L‑24C‑DUAL is ideal for:
- Residential split systems using A2L refrigerants
- Package units transitioning to R‑32 or R‑454B
- Commercial air handlers
- Industrial A2L detection zones
- OEM equipment integration
- Retrofit applications requiring compliance with A2L safety standards
As regulations continue to evolve, this board helps contractors and OEMs stay ahead of code requirements and safety standards.
A Stronger, Smarter, Safer HVAC Future
ICM Controls has a long history of building durable, American‑made HVAC control electronics—and the ICM‑UA2L‑24C‑DUAL reflects that legacy.
