I have just moved into a new house that has a baxi Bermuda back boiler and Honeywell st699 control panel. When we first moved in a few days ago the heating worked fine,however now it's not doing anything. I have lit the pilot and it is staying on, but the boiler isn't firing. The thermostat is turned up, but there is no lcd display on the control panel. I have checked and there isn't any tripped fuses in the fuse box. I'm guessing this something to do with it?
