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) FD-series indoor units are also listed. They connect over the X-Y terminal bus using the Faikin Ninja P1P2 (MHI) module, no Faikout cable required.

Compatibility note

Faikin Faikout is compatible with indoor units in single-split and multi-split/multi-head setups.

VRV/VRF systems are commercial or high-end domestic setups where one outdoor unit can run many indoor units. Not all multi-split or multi-head systems are VRV/VRF, so if you're unsure, it's worth checking.

Faikin Faikout is not currently compatible with VRV/VRF systems.

VRV/VRF systems are found in apartments and condos with shared outdoor equipment, as well as offices and large residential installations. They can often be identified by a blue “VRV” sticker on the outdoor unit. Some indoor units may look the same and have the same model numbers as standard split systems, but use a different communication system in a VRV/VRF setup.

If you're not sure whether your system is VRV/VRF, get in touch with your setup details and we can advise.

All Faikin Faikout purchases are covered by our no-risk returns policy. If your kit isn't compatible with your unit, return it for a full refund.

* This indoor unit can run on either a Sky Air or a VRV/VRF system. On Sky Air, the Faikin Faikout OG (Type C cable) works. On a VRV/VRF system the unit’s X50A port is disabled, so order the Faikin Ninja P1P2 instead. Check your outdoor unit or system type before ordering.

About P1P2 (see note) results: these are commercial Daikin systems (VRV, Sky Air and similar) that use the P1P2 protocol instead of the S21 / X50A buses the Faikin Faikout speaks to. A Faikin Faikout cable will not work on these units.

We have a P1P2 module in development with our partners in Vietnam, but it is not yet available. In the meantime, customers with P1P2 systems should look at Arnold-n's P1P2MQTT project or the GS Smart Home Facebook group. Both are active communities supporting P1P2-based Daikin control.

About Unknown, help us classify results: we have this model in our database but have not yet confirmed which cable it needs. Get in touch via the contact form with your indoor unit model number, and a photo of the control board if you can manage it. We will work it out, get you the right cable, and update this finder so the next person who lands here with the same unit gets a straight answer. You will be doing the next customer a favour.
