Hi i have had a ferroli ov system running all has been well for first few weeks now the it keeps on giving a flow sensor fault. If i move the thermostat on the cylinder lower it will restart if the temp on the stat is higher ie not pumping , it refuses to light and gives fault code for flow sensor . If i keep the stat at a lower temp it runs for approx 10 to 20 minutes then gives flow sensor . My plumber says there is air in the system but i cant get any out of the radiators . Any help would be appreciated thanks .
