Question: Why is the heating system making noise?

Possible cause of the fault

The flow rate is too high

This can be resolved by setting the pump to a setting other than "AutoAdapt"

Note the pump setting that appears on the display.

Then use Button 5 to switch the pump to "AutoAdapt". (for MAGNA, use Button 3)

If the supply of heat is sufficient at this point, leave it at this setting.

If the supply of heat is not sufficient, restore the previous setting using Button 5 (for MAGNA use Button 3), and then call your installer.

The air in the system.

Remedy
