New update -- heating is now gone off.
Stat still demanding heat as turned up to 30° - clicks at 20° indicating the room temp, programmer still on and demanding. Boiler heating water temp was 60° but could of been higher when I wasn't looking.
Temp on boiler now down to 55°
Getting 246V between Blue and brown block.
Looks like its back to its behaviour where it now will not come back on until the indicated CH water temp is down to around 30°
