COMMAND_CLASS_THERMOSTAT_SETPOINT
This CC can be used to manage the boiler setpoints.
N.B.
The maximum and minimum value of the setpoints are displayed with the COMMAND_CLASS_CONFIGURATION.
This was done to support a non-exclusion/inclusion boiler hot swap. It is also important to know that setting the heating
setpoint to 0 is equivalent to setting it to the maximum reported by the boiler. Otherwise, setting the DHW setpoint to 0 is
equivalent to setting it to 40 ° C. The map between the 'mode' and the setpoint is as follows, while the unit of each
measurement is correctly communicated in the command class report message.
