|

* 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
|
||||
