The heating system is making noise.

Possible cause of 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".

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, and then call your installer.

Possible cause of fault

Air in the system.


These faults can only be remedied by a specialist company.
