The macro generates a calculated heating demand depending on the value of the parameter SYS-05:
In this case the calculated heating demand setpoint equals the calculated DHW temperature setpoint plus a setpoint increase to compensate losses defined by parameter SST-01.
When the DHW is charged with renewable energies, e.g. a solar panel, and the input "RenEnergCharge" = 1, the heat demand will be reduced by the value of the parameter SST-03.
