Hi,
several days ago the pressure sensor of my boiler was changed. After that the boiler was working OK and was keeping the pressure 1.7 bars. Today I put the termostad down and the heating stop working for 2-3 hours. I noticed that the pressure was 0.3 bars and flashing. I put the termostad up and, the pump began to work and the pressure jumped t0 0.7 bars. The heating began to work and and after about an hour the pressure settled again to 1.7 bars. In this pressure the arrow of the analog manometer is in the beginning(2mm) of the grey zone. Any idea what is big change of the pressure.
