We have a Drayton Digistat RF1 (pic below) and although it has the
temperature on it and the flame next to it, adjusting the temperature on
the screen seems to do absolutely nothing to the actual temperature of
the house. I can't remember if there have ever been any LEDs on the unit
and wouldn't know where they are anyway.

I've found this link -

but have no idea what an SCR is (sorry, complete novice at this) and no
idea how I can make it work. My initial thought is that it has lost
connection with the boiler system but in all honesty, I just can't
remember if the thing ever worked in the first place.

Have you used a thermometer to see if the location of the
thermostat is actually reaching its set temperature?

Do you have thermostatic radiator valves?

Do the radiators get warm?

Is there a radiator near the thermostat?

If the Digistat is not controlling your system (details of which
might help) what do you conclude is causing the boiler to
operate?
