I had the same problem with the boiler not starting up when the Thermostat said that i was sending the signal. It turnout to be a fault with the box with the flashing lights on and not the thermostat, according to the engineer its a common fault after a couple of years!
I have a different problem now, the digits on the RC Plus thermostat screen are broken up so some bits are missing, it still works fine, but difficult to tell what the temp is... anyone had this and know how to fix it without having to replace it?
