I have a Drayton Digistat 3 RF control system on my central heating. The two units are not communicating - I do not get the 7 flashes on the controller when the thermostat calls for heat. How can I tell which unit is faulty, or do I just replace the whole system?

try changing the batteries this sometimes works,make sure you follow the re-commissioning guide properly and if you still dont get any luck sounds like the digi stat is faulty.
