Limitations:
- Total number of supported indoors (for all HVAC Lines) can not exceed 255 units
- *When DIP switches P1 and P2 are "ON", lines L6 and L7 cannot be used as separated lines. In this case the polarity on the HVAC cable connected to L7 will be automatically detected.
- **Line L2 can not be connected simultaneously with line L6 and line L1 can not be connected simultaneously with line L5.
