SDIBS9DC m3/h If the resistances in the air distribution system are too high, the air flow to the outlet grilles can be excessively reduced. In this case it is possible to increase the air flow corresponding to each selected speed by removing the jumper on JP2 of the board as follows.
15 - OUTDOOR/INDOOR UNIT REFRIGERANT CIRCUIT ADDRESS Indoor units that are part of a multisplit system must be properly configured to be able to communicate with the outdoor unit over different channels (Indoor A, Indoor B, etc...) of the communication bus. Each indoor unit address must correspond to the physical connection of the indoor unit to the outdoor unit refrigerant circuit, i.e.: Refrigerant Circuit A <-->...
