sends a control command to the indoor units. Therefore, be sure to send a command to the Modbus master only when 
control (operation on/off, temperature setting, etc.) is required.

If an identical command is issued consecutively, the same command is repeatedly sent to the indoor units.
To check whether the write command operates normally, send a write command to the master and then read the register 
status.
