ARISTON ACO 27 MFFI with the boiler.
I have Error A03 Overheating 105 deg despite of all sensors are OK.
I have checked all NTC (1,2,3), connectors, parameters and there is no problem.
The ACO 27 starts pump and ventilation. On the cnob I can set temperature central and domestic.
When I press 10s RESET and MENU button there is monitored value 20deg on NTC1, 19deg on NTC2, and 21deg on NTC3 (boiler).
Where is problem ? What can I do ?
