Help please, because I am totally bemused!
I have for years run my Worcester Combi boiler using a Digistat British Gas badged RC5 RF unit.
This has now "expired" after many years, and I had hoped to simply replace it with Digistat+2 RF unit (22084). However all is not going to plan.
I have retained the existing SCR unit; it seems to be doing what it says on the tin and still seems to be working fine (if it ain't broke why fix it?)
As far as I can see from the diagrams the wiring is the same; I believe that the operating frequency is the same (433); and although I can’t find online a set of commissioning instructions that appertain to this particular model (22084), they all appear to be the same regardless of model.
I have attempted to commission and re-commission repeatedly without success
However the red LED does not flash to indicate a mate between SCR & RF unit, and the Red LED remains lit
When these 2 units syn is one the control unit? As it stands the SCR simply does not know the RF unit exists!
It has to be something simple because the procedure is simple!
So please what or where is the hick-up; or am I just missing a simple trick?
Any advice is appreciated
