Information About M4-CVE03050-0P

The Johnson Controls M4-CVE03050-0P is a VAV (Variable Air Volume) box controller with an integrated actuator, designed to streamline airflow control in HVAC systems. This product is engineered for VAV box applications, where precise airflow and temperature regulation are critical for ensuring energy efficiency and maintaining optimal indoor environmental conditions. The integration of the controller and actuator into a single device simplifies installation, reduces the need for multiple components, and enhances system performance, making it a suitable choice for modern HVAC systems in commercial, industrial, and institutional settings.

One of the key features of the M4-CVE03050-0P is its integrated actuator with position feedback. This allows the controller to accurately monitor and adjust the position of the VAV box damper, ensuring that airflow is regulated with precision according to the system’s requirements. The feedback mechanism is facilitated by an integral potentiometer, which senses the actual position of the damper. This real-time position feedback allows the controller to adjust the damper position dynamically, improving system efficiency and ensuring that the desired air volume is maintained at all times.

The controller is equipped with a digital Differential Pressure Transmitter (DPT) sensor, which further enhances its ability to monitor and control airflow. The DPT sensor provides accurate measurements of the differential pressure across the VAV box, allowing the system to adjust airflow based on real-time pressure readings. This ensures that the system operates within the desired parameters, providing optimal airflow to different zones within the building, while also improving energy efficiency by minimizing over- or under-conditioning of spaces.

The M4-CVE03050-0P supports BACnet/IP communication, which allows it to seamlessly integrate with building automation systems (BAS). BACnet/IP is a widely used communication protocol in HVAC systems, enabling the controller to communicate with other devices and systems within the network. This capability ensures that the controller can be easily monitored and controlled remotely, providing building operators with real-time access to system data, alarms, and status updates. The integration with BAS also allows for more comprehensive control strategies, enabling operators to optimize energy use and system performance across the entire building.

The controller includes eight input/output points, providing the flexibility needed for various system configurations. These I/O points are divided into three universal inputs (UI), two configurable outputs (CO), and three binary outputs (BO). The universal inputs can be configured to accept a wide range of signals, including temperature, pressure, or occupancy data, providing the controller with the necessary information to make informed control decisions. The configurable and binary outputs allow the controller to control other devices within the system, such as dampers, valves, or fans, enabling it to execute a wide range of control strategies.

Powering the M4-CVE03050-0P is a 24 VAC input, making it compatible with standard HVAC power supplies. This ensures that the controller can be easily integrated into existing systems without the need for extensive modifications or additional power supplies. The 24 VAC power input is a common specification in the HVAC industry, allowing for straightforward installation and reducing the overall complexity of the system.

At the heart of the M4-CVE03050-0P is a 32-bit microprocessor, providing the controller with the processing power necessary to handle complex control algorithms and real-time data processing. The 32-bit architecture ensures fast, efficient operation, allowing the controller to respond quickly to changes in the system and make precise adjustments to airflow and temperature control. This powerful microprocessor enhances the controller’s ability to manage dynamic HVAC environments, where conditions can change rapidly depending on occupancy levels, external weather, or other factors.

One of the standout features of the M4-CVE03050-0P is its support for 14 preloaded standard applications. These applications are designed to operate standard VAV box equipment with a proven, energy-efficient sequence of operation. By leveraging these preloaded applications, building operators can quickly deploy the controller in a variety of VAV box configurations without the need for extensive programming. This reduces setup time and ensures that the system operates with optimal efficiency from the outset. Additionally, for more specialized applications, the controller is fully programmable using Johnson Controls’ Controller Configuration Tool (CCT), providing the flexibility to create custom control sequences tailored to the specific needs of the facility.

The M4-CVE03050-0P also features a real-time clock, which enhances its ability to execute time-based control strategies. The real-time clock allows the controller to operate according to schedules, adjusting airflow and temperature settings based on the time of day, occupancy levels, or other factors. This feature is particularly useful in commercial or institutional buildings, where energy savings can be achieved by reducing airflow or adjusting temperature settings during unoccupied periods, such as nights or weekends.

In summary, the Johnson Controls M4-CVE03050-0P VAV box controller with integrated actuator is a robust and versatile solution for modern HVAC systems. Its features, including position feedback, a digital DPT sensor, BACnet/IP communication, and support for both preloaded and custom applications, make it an ideal choice for applications requiring precise airflow control and energy efficiency. With a 32-bit microprocessor, eight I/O points, real-time clock, and compatibility with 24 VAC power supplies, the M4-CVE03050-0P provides reliable, efficient, and flexible control for variable air volume systems in a wide range of environments.
