hi all, just looking for some assistance please, we’ve got the British gas branded, Wr1 digistat reciever. Which I believe is rebranded from a Drayton SCR. I believe this unit has died, but don’t seem to be able to find just the SCR available for purchase.So you have to buy the Scr and the Wireless thermostat. If I did this, and Just replaced the SCR, would I be able to just link up the New SCR, to the current. wireless thermostat, through the linking process? I’m thinking that I can go for a cheaper version of the two, as it’s just the SCR that I want and not the features from the Thermostat.
