The 3 heating circuits and DHW heating are ready connected to the main controller,
which means that they cannot be operated by the primary controller, but only parallel to it.
The primary controller also is ready connected to the main controller and cannot be
operated parallel to the main controller.
The main controller in turn is ready connected to the boiler. The heat distribution zone
on the heat generation side need be set only when there is no boiler.
During boiler operation, the heat demand is acquired via the heat distribution zone. If
no main controller is used, its plant elements, such as mixing valve and pump, will not
be needed.
