Wiring Diagrams
The document includes several wiring diagrams illustrating the electrical connections for the system:
- External Wiring Diagram (Page 2): Shows the connections between the outdoor unit, indoor units (twin type), and the wired remote controller. It indicates power supply, signal lines, and grounding points.
- Outdoor Unit Internal Wiring Diagram (Page 4): Details the internal electrical components and their connections within the outdoor unit, including control boards, compressor, fan motors, sensors, and various protective devices (fuses, switches).
- Indoor Unit Wiring Diagram (Page 6): Illustrates the internal wiring of the indoor unit, showing connections to the control board, fan motor, sensors, and optional components like drain pumps or air purification electrodes. It also shows connections for wired and wireless remote controllers, and central control systems.
These diagrams are crucial for installation and maintenance, showing component identification (e.g., CN for connector, F for fuse, M for motor) and wire routing.
Remote Controller (RBC-AMSU52)
The system utilizes a wired remote controller (Model: RBC-AMSU52, "Energy Saving Neo Remote Controller"). The document provides installation instructions and dimensions for mounting the controller on a wall.
Key installation notes include:
