LFCR.
CR = Carriage Return (Hex: 0D); LF = Line Feed (Hex: 0A)
The response from the thermostat is always made with a CRLF.

After each command sent to the thermostat, it is necessary to wait for

the reply before sending another command. This ensures that the
sequencing of inquiries and answers is clear.
