/********************************************************************************
* Airconditional remote control encoder for:
*
* ZH/LT-01 Remote control https://www.google.com/search?q=zh/lt-01
*
* The ZH/LT-01 remote control is used for many locally branded Split
* airconditioners, so it is better to name this protocol by the name of the
* REMOTE rather then the name of the Airconditioner. For this project I used
* a 2014 model Eurom-airconditioner, which is Dutch-branded and sold in
* the Netherlands at Hornbach.
*
* For airco-brands:
* Eurom
* Chigo
* Tristar
* Tecnomaster
* Elgin
* Geant
* Tekno
* Topair
* Proma
* Sumikura
* JBS
* Turbo Air
* Nakatomy
* Celestial Air
* Ager
* Blueway
* Airlux
* Etc.
*
***********************************************************************************
* SUMMARY FUNCTIONAL DESCRIPTION
**********************************************************************************
* The remote sends a 12 Byte message which contains all possible settings every
* time.
*
* Byte 11 (and 10) contain the remote control identifier and are always 0xD5 and
* 0x2A respectively for the ZH/LT-01 remote control.
* Every UNeven Byte (01,03,05,07 and 09) holds command data
* Every EVEN Byte (00,02,04,06,08 and 10) holds a checksum of the corresponding
* command-, or identifier-byte by _inverting_ the bits, for example:
*
* The identifier byte[11] = 0xD5 = B1101 0101
* The checksum byte[10] = 0x2A = B0010 1010
*
* So, you can check the message by:
* - inverting the bits of the checksum byte with the corresponding command-, or
* identifier byte, they should me the same, or
* - Summing up the checksum byte and the corresponding command-, or identifier byte,
* they should always add up to 0xFF = B11111111 = 255
*
* Control bytes:
* [01] - Timer (1-24 hours, Off)
* Time is hardcoded to OFF
*
* [03] - LAMP ON/OFF, TURBO ON/OFF, HOLD ON/OFF
* Lamp and Hold are hardcoded to OFF
* Turbo is used for Cool and Heat is case of FAN_4 or FAN_5
*
* [05] - Indicates which button the user _pressed_ on the remote control
* Hardcoded to POWER-button
*
* [07] - POWER ON/OFF, FAN AUTO/3/2/1, SLEEP ON/OFF, AIRFLOW ON/OFF,
* VERTICAL SWING/WIND/FIXED
* SLEEP is used for FAN_SILENT
* FAN_4 and FAN_5 are not supported, coded to FAN_3 or Turbo (byte [3])
* Vertical Swing supports Fixed, Swing and "Wind"
* VDIR_AUTO = Wind
* VDIR_SWING = Swing
* All others = Fixed
*
* [09] - MODE AUTO/COOL/VENT/DRY/HEAT, TEMPERATURE (16 - 32°C)
* MODE_MAINT is not supported, but implemented as MODE_DRY at 30°C
