13. HEATING CIRCUITS

For the heating circuits, a number of functions are available (see parameters table) which can be individually set for
each heating circuit. Every heating circuit can be a virtual circuit, pump circuit or mixing circuit. The Mixing function is
available only when an external extension module (AGU2.550A109) is needed.
If, with the mixing circuit, the flow sensor of that circuit is not connected, it becomes a pump circuit with regard to
functions.
Every boiler is able to control 3 heating circuits with mixing function (3 extension modules are needed). It is necessary
to give power supply and a bus connection to each extension module (AGU2.110).
