What

Adds climate codes for the Daikin RB2CA1 remote (India market), e.g. paired with indoor unit FTKZ50UV16U4.

Coverage (Cool mode)

  • Temperature: 18–30 °C, 1° steps
  • Fan modes: auto, 1, 2, 3, 4, 5, turbo (powerful)
  • Swing modes: off, vertical, horizontal, both
  • Power: off command

All codes were generated from a reverse-engineered model of this remote's IR protocol (not individually learned). Full write-up + reproducible generator: https://github.com/adityasanehi/daikin-rb2ca1-ir-reverse

Spot-tested on the real unit via a Broadlink RM4 (25 °C codes across all fan modes, swing on/off, power off — user-verified).

Notes

  • Other modes (heat/dry/fan) were not captured for this unit; the file covers Cool only, which is how this unit is used in this market.
  • The both swing state and turbo+swing combinations are generated per the protocol model but were not individually captured; single-axis swing states were captured and verified.

Reverse-engineered 72-bit protocol. Cool mode: 18-30C,
fan auto/1-5/turbo, swing vertical/horizontal/both, off.
Validated against all captures + tested on real AC via Broadlink RM4.
