What does the fault code Main PCB damaged (LED 65° 60° 55° 50° 45° 40° 35°) mean on Unical?

Main/modulation board damaged: the boiler is locked. Fault in the modulation PCB (board 00260145‑03) due to component damage or power/firmware issues; verify by resetting the network, checking connections/harness and board voltages; if it persists, replace the PCB.

What does the code REGOLAFACILE 19 mean in Unical?

Alteration of factory parameters (lock). Corruption/alteration of parameters in the modulation PCB; if it does not disappear after reset, Unical itself indicates replacing the PCB (memory/EEPROM of the PCB).
