Description
The Johnson Controls C550CCN-001 is a versatile System 550 Control Module engineered for modern HVAC applications that demand precise environmental monitoring, refrigerant safety compliance, and flexible output control. Designed to meet the growing requirements of A2L refrigerant installations, this module delivers integrated leak sensing and mitigation capabilities alongside robust multi-sensor and multi-output functionality.
Key Features
- 3 universal sensor inputs for flexible temperature, humidity, or other environmental monitoring configurations
- 2 relay outputs for direct equipment control and safety interlock applications
- 0–10 VDC analog output for proportional control of variable-speed drives, damper actuators, and other modulating devices
- Integrated A2L refrigerant leak sensing and mitigation support — designed to help meet safety codes for next-generation low-GWP refrigerants
- Optional wireless connectivity for remote monitoring, configuration, and integration into building automation systems
A2L Refrigerant Compliance
As the HVAC industry transitions to A2L mildly flammable refrigerants such as R-32, R-454B, and R-410A replacements, the C550CCN-001 provides built-in leak detection and mitigation logic to help installers and building owners meet evolving safety standards. This makes it an ideal control solution for new equipment installations and retrofits involving A2L refrigerant systems.
Flexible I/O & Connectivity
The System 550 platform’s modular architecture allows the C550CCN-001 to serve a wide range of commercial and light industrial HVAC control applications. The 0–10 VDC output enables smooth, proportional control of downstream devices, while the dual relay outputs provide dependable on/off switching for fans, pumps, alarms, or other loads. The optional wireless connectivity option simplifies integration into networked building automation environments without the need for additional wiring infrastructure.
