Hello, thank you for contribution.

1. Please do not modify CLIMATE_CODES.md, it is autogenerated.Please revert this commit.
2. Did you checked preset modes support for climate devices? It is now for testing in the beta release If your AC units support something like 'eco' or 'hi-power' modes those could be added.

Hello,
it seems that your PR is failing Lint job. There was recently update for changed-files workflow which might be fix. Could you please close this PR, pull & merge master into your repo branch and create new clean PR? In addition I think you are missing "temperatureUnit": "C", entry in you file (this would be checked and detected by Lint if not failing).

Hi @litinoveweedle
There is no turbo or eco mode on this AC model. The only two extra functions there are are:

• 'Ionizer' mode, which I have never turned off. All codes were recorded with it on. Maybe this one could be used as preset?
• Air flow direction (flap). I recorded all codes with this set to auto. This corresponds to the swing_mode of the Climate integration. That would take me ages to record all codes for each swing mode, I might do it later but I would prefer to already get current code file, which I've been using with upstream SmartIR for a while, merged, if that's fine with you.

I'll add the missing temperature unit.

I've also rebased from latest master which should fix the Lint issues without having to recreate a PR.
