    Have you the controller paired to both units? Are both indoors compatible with the outdoor?
    Mostly found in the southern part of this green and pleasant land.

    The controller connects to one unit p1&p2 then the 4 core goes from one to the other unit according to Daikin but only the one with the controller connected to it operates. It’s as if it needs to be set to master and slave but can’t figure out a way

    Users start by inputting their outsourced it services priorities and preferences into the AI system. For instance, someone interested in purchasing a smartphone might prioritize a high-quality camera, ample storage, and a long-lasting battery.
