Not sure about:

1. The "device_code" number. Feel free to propose another "device_code" number that better suits the project.
2. The specific Daikin FWT-GT series models have some Peculiarities. Specifically:

• The "fan_only" operationMode, has no "powerful" fanModes, and no temperature control . I just copied the same codes everywhere. Let me know if there are any changes required here.
• The "dry" operationMode, has no fanModes. I just copied the same codes everywhere. Let me know if there are any changes required here.
