Note!
In the case of continuous heating (no setback periods), DHW charging is released at
00:00.
This is also the case if the first request from the heating circuit is received before the
set forward shift for charging after midnight.
If the heat request is received exactly at midnight, DHW heating is released after the
last setback period, but at the earliest for the set forward shift for charging before
midnight.
