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).
