Hi, I was wondering if anyone could help me. I have a ferroli optimax boiler with a volt free drayton digistat 2 thermostat. The problem I'm having is my boiler seems to be ignoring my thermostat. I've recently changed the batteries in the stat but to no avail and tested the continuity of the switch and everything seems to be working ok. The boiler works fine when pressing the overide button on the boiler. Does anyone have any suggestions please.
Many thanks for your help in advance
