Adaptors & Controls for Split / SkyAir

Centralized Controls

Daikin Split and SkyAir units can be connected to all Daikin Centralized Control solutions.

For Split indoor units, a KRP928A2S adaptor is needed for every indoor unit
For SkyAir indoor units, no adaptor is neccessary if the unit already has F1/F2 connection terminals (see wiring diagram - most newer units), else a DTA112B51 is neccessary.
