The heat distribution zone on the heat generation side can only be set when using a
main controller without boiler. It will not be required when using a boiler.
The heat distribution zone on the consumer side can only be set when used in
connection with a primary controller.
In the following plant, boiler and DHW are accommodated in controller 1, and main
controller and heating circuits in controller 2. The example shows clearly the role of the
main controller as the interface between 2 zones. It receives the heat requests and
generates the resulting heat demand, which is forwarded to the boiler.
Boxes "Controller 1" and "Controller 2" at the bottom show the zone settings.
