In mini-split systems, the communication cable serves as a critical link between the indoor and outdoor units. Its primary functions include:
-
Data Transmission: Facilitates the exchange of control signals, allowing the indoor and outdoor units to synchronize operations like temperature adjustments, fan speeds, and cooling/heating modes.
-
Power Supply: Often carries power to the indoor unit (if not separately wired), simplifying installation.
-
Error Reporting: Transmits diagnostic information and error codes, helping to identify and troubleshoot issues efficiently.
The communication cable ensures that both units operate harmoniously, providing optimal performance and energy efficiency.
