Find the right cable
Every Daikin indoor unit connects to a Faikin Faikout module using one of seven cable types. The cable you need depends on which socket is on your indoor unit's control circuit board. Mitsubishi Heavy Industries (MHI) ducted and VRF systems on the X-Y bus are also covered.

* Units marked Type C * or Type F * have two control paths: the X50A port (Faikin Faikout with the marked cable) or the P1/P2 bus (Faikin Ninja P1P2). On VRV systems we recommend the Ninja P1P2. Not sure which suits your setup? Contact us with your model and system details.
