Note:
The SI (signal) wire between the indoor and outdoor units is not applicable when the outdoor unit is connected to an indoor unit of a
different brand. In a matched system, SI (signal) enables more energy-savings when the outdoor unit is connected to an indoor unit
of the same brand. SI (signal) is not required in non-matched configurations.
