We have just moved to a property which has a RD532 combi boiler, which appears to be controlled by a RC5 wireless thermostat. This has a British Gas logo on it, but following some research I think it's the same as a Drayton RF3. I have lost the will to live while trying to programme the damned thing, however the worst issue is this: it appears to be impossible to set the temperature below 16C if the selector pin has been removed (which of course it has). Does anyone know if I can buy a replacement pin anywhere?
