[Note]: Serial set speed overwrite status/command:
00h – Serial set speed does not overwrite the thermostat set point
01h – Serial set speed overwrites the thermostat set point
Remark: if there is no serial communication for more than 4 h then the overwrite
command is resetted.

Note 1 : This response occurs when compressor is running with a high load. If the
Data High byte is 00h, compressor is still running.
Note 2 : Response to the out-of-spec set speed data received while the comp is
running.
Note 3 : This response occurs when compressor is stopped due to high load.
Note 4 : Response to the out-of-spec set speed data received while the comp is
