My boiler is in continuos S40 mode. A reset fixes for a while and then it comes back. There are no f codes and the only other possible problem is the diagnostic code 118 reports 8 which is the CO2 sensor . The manual says that this number means Standy Reference resistance not OK . It has been like this for a long time . Does anybody know if this would cause boiler limiting ?
