My new Domusa oil boiler MCF DXV shows "error 81" on the remote programmer E20. And the manual explains that it is a problem of "EEPROM" or adjustment required in the Accumulator regulator.
When the technician came to start up the boiler, he didnt know what the error meant.
Some problems I have: when I set the programmer to reduce the temp of hot water to 22 C, it usually just returns by itself to 50 C.
Or when I try to turn off all hot water completely, just leaving the boiler prepared to turn on at 5C for the coldest winter months (when the house may be empty), the programmer still turns on the hot water anyway. So I can't actually turn off the hot water to the taps. I don't know if these faults are connected with the "error 81" message...any help greatly appreciated.
