What does it mean when my Ferroli Boiler displays a limit thermostat fault?

If your Ferroli Boiler is displaying a limit thermostat fault with parameter b06 = 1 or 4, this can be due to no or poor water circulation in the system. Check the circulating pump and heating system. It could also be caused by air in the system, so vent the system. Another possible cause is an incorrect parameter setting, so check the correct parameter setting.
