Step 4 : aggregation of the DHW flow/power with the CH flow/power at CH side
Within one dwelling we will aggregate the DHW and CH flows/powers using the “maximum method“ as explained in Step 6 : aggregation of the DHW flow/power with the CH flow/power | Maximum of central heating and diversified DHW flow .
Why? Either the HIU is in DHW tapping mode, either the HIU is in CH mode.
