GT15-60ATT-87 MITSUBISHI Central Control Unit

Product  Description：

The Mitsubishi Electric Central Control Unit (CCU) serves as the primary intelligence hub for large-scale integrated systems, most notably within Variable Refrigerant Flow (VRF) HVAC systems and advanced building management architectures. These units are designed to consolidate the management of multiple individual sub-controllers or indoor units into a single, cohesive command center. By utilizing proprietary high-speed processing and networking, the CCU optimizes energy distribution, schedules operations, and provides a centralized interface for complex system monitoring.

Product Parameters

Technical specifications for a typical Mitsubishi Central Control Unit reflect its role as a high-capacity system coordinator:

• System Capacity: Capable of managing up to 50 or 100 individual indoor units and multiple outdoor refrigerant circuits from a single interface.

• Power Supply: Operates on standard 100V–240V AC, with internal power management for low-voltage communication buses.

• Communication Bus: Utilizes the M-NET (Mitsubishi Electric Network) transmission line, which provides a non-polar two-wire data link.

• Display and Interface: High-resolution backlit touch panel (often 5 to 10 inches) with support for multi-language graphical user interfaces.

• Connectivity Ports: Integrated Ethernet (RJ45) for LAN/Internet access, along with specialized ports for BACnet or LonWorks integration.

• Data Logging: Internal non-volatile flash memory capable of storing up to one year of operation logs and error histories.

Product Advantages

Mitsubishi Central Control Units provide sophisticated benefits that enhance both user experience and system efficiency:

• Precision Energy Management: Allows for peak-cut control and energy-saving modes that can reduce total power consumption by up to 30 percent through intelligent load distribution.

• Centralized Visualization: Provides a "bird's-eye view" of the entire facility, allowing facility managers to identify malfunctions or inefficiencies in specific zones instantly.

• Advanced Scheduling: Supports complex 24-hour and weekly schedules, including holiday exceptions and seasonal adjustments, ensuring the system only runs when needed.

• Web-Based Accessibility: Built-in web server functionality allows authorized users to monitor and control the system via a web browser on a PC or smartphone without additional software.

• Proactive Maintenance: Features advanced self-diagnosis tools that provide specific error codes, significantly shortening the time required for technical repairs.

Product Applications

These units are deployed in environments where multi-zone control and energy accountability are paramount:

• Commercial Office Buildings: Managing climate control across multiple floors and departments to balance comfort with operational costs.

• Hotel and Hospitality: Providing the front desk with centralized control over guest room temperatures while allowing for individual room overrides.

• Educational Institutions: Coordinating HVAC and ventilation across classrooms, gymnasiums, and laboratories according to school schedules.

• Healthcare Facilities: Ensuring precise temperature and humidity control in sensitive areas like operating rooms and pharmacies.

• Shopping Malls: Regulating the environment in large open atriums and individual retail units from a central management office.

Important Precautions

To ensure the safety and reliability of a Central Control Unit, the following guidelines must be followed:

• Transmission Line Interference: M-NET communication lines should be kept at least 50mm away from power cables to prevent electromagnetic interference that can cause communication drops.

• Static Discharge: The internal circuitry is sensitive to static electricity. Always touch a grounded metal surface before interacting with the internal wiring or circuit boards.

• Correct Addressing: Every indoor unit and sub-controller must have a unique M-NET address. Duplicate addresses will cause system-wide communication failures and logic errors.

• Indoor Installation Only: These units are not weather-rated. They must be installed in a clean, dry, indoor environment away from direct sunlight and sources of vibration.

• Software Updates: Only perform firmware or software updates using official Mitsubishi Electric tools. A power interruption during a firmware flash can permanently damage the unit's operating system.
