Johnson Controls C450CCN-4 Control
The Johnson Controls C450CCN-4 is a versatile Standard Modular Control designed for high-performance HVACR applications requiring precision and scalability. This unit serves as the direct replacement for the C450CCN-2, featuring a robust 4-button touchpad interface and a high-visibility LCD for real-time parameter monitoring. Engineered for dual-stage control, it provides two SPDT line voltage relay outputs, making it ideal for managing complex sequences in heating, cooling, or ventilation systems. The controller operates on a 24 VAC external supply power and supports 0-5 VDC analog inputs, ensuring seamless integration with standard humidity sensors and static pressure transducers. Its modular architecture allows for easy expansion via C450 stage modules, enabling contractors to customize setpoints and differentials across multiple stages. Built for professional-grade reliability, the C450CCN-4 minimizes downtime through its intuitive configuration menu and field-removable terminal blocks, streamlining HVAC system troubleshooting and installation processes.
Key Benefits
- Dual SPDT Relay Outputs: Provides versatile line voltage switching for independent control of two stages or components.
- Sensory Integration: Compatible with ratiometric transducers and active sensors for precise monitoring of pressure, temperature, and humidity.
- User-Friendly Interface: The 4-button touchpad and backlit LCD simplify field commissioning and parameter adjustments.
- Modular Scalability: Easily expands with add-on modules to accommodate additional relay or analog outputs as system requirements grow.
- Input Flexibility: Supports a wide range of input types, including A99 temperature sensors, ensuring compatibility with existing infrastructure.
Common Questions
Can the C450CCN-4 replace an older C450CCN-2 unit?
Yes, this model is the direct functional replacement for the discontinued C450CCN-2, offering the same footprint and updated electronics for improved stability.
What power source does this modular control require?
The unit requires a dedicated 24 VAC, Class 2 power supply to operate the internal logic and the onboard display interface.
Which sensors are compatible with this controller?
It is designed to work with Johnson Controls A99 series temperature sensors, as well as any static pressure transducer or humidity sensor providing a 0.5 to 4.5 VDC or 0 to 5 VDC signal.
