2. When repairing, PQ connects after-sales tooling
3. PQ and M1M2 communication ports both are used for indoor and outdoor communication, and only one of them can be used at a tim e. Meanwhile, be
sure to connect the same communication ports (PQ to PQ; M1M2 to M1M2) in case of damage of the main control board.
4. D1D2 communication ports are used for group control communication. When connecting the group controller, the D1D2 port of the indoor units that are
to be group controlled must be connected in daisy chain, and the group controller must be connected to the X1X2 port of one of the indoor units in the
group control, and set to group control mode. In addition, D1D2 communication ports can also be connected to the central controller.
