My Drayton RF1 wireless room stat is no longer turning the heating on & off. I have replaced the batteries (although I don't think they needed replacing) and have recommissioned the SCR. The SCR red light did not flash to say that it was receiving a signal when I tried to pair it with the RF1 room stat. Both red and green lights on the SCR are on. I can control the heating by the programmer, but that is far from ideal.
Any ideas as to what might be wrong?
