How to get or find CarrierAc 32 bit protocol?

[Solo157]

In this project there is ir_Carrier.h file where I see protocol structure for Carrier 64 bit

union CarrierProtocol { uint64_t raw; ///< The state of the IR remote. struct { // Byte 0 uint8_t :8; // Byte 1 uint8_t :8; // Byte 2 uint8_t Sum:4; uint8_t Mode:2; uint8_t Fan:2; // Byte 3 uint8_t Temp:4; uint8_t :1; uint8_t SwingV:1; uint8_t :2; // Byte 4 uint8_t :4; uint8_t Power:1; uint8_t OffTimerEnable:1; uint8_t OnTimerEnable:1; uint8_t Sleep:1; // Byte 5 uint8_t :8; // Byte 6 uint8_t :4; uint8_t OnTimer:4; // Byte 7 uint8_t :4; uint8_t OffTimer:4; }; };

and also I see file with decoding it https://docs.google.com/spreadsheets/d/1EZy78L0cn1KDIX1aKq2biptejFqCjD5HO3tLiRvXf48/edit#gid=0

But I can't find nowhere information for Carrier 32 structure and I can't find see file with decoding it for Carrier 32 bit.
There is not such information in ir_Carrier.h file.
So I need CarrierAc for sendCarrierAC method.
Please, help me find it out?
