same outdoor unit and the MS should be in common use.
3. The MS power wire should be connected to the terminals with the label “L, N”, and the MS signal wire
should be connected to the terminals with the label “P, Q, E” and correspond to the “P, Q, E” wiring
terminals for the outdoor and indoor units, which cannot be wrong connected. Please refer to the following
