Combi 80 Boiler exceeds the Drayton RF1 Thermostat temp setting?
I have replaced both the Overheat and Frost Thermostats but still no joy!
Would appreciate any suggestions as the only solution I can see is opening a Sauna.

Have you fixed your fault, my Combi 80 does the same and I have tried replacing both the Overheat and frost Thermostats but still the Radiators and Boiler are exceeding the Room Stat temp?
