Hi Rab, have wired many of these but never seen grey and black from CN5 to the Tyco plug, always been red and black on a Compact A, you learn something new every daygray and black from CN5
Not all Ian, you're right, all the one's I've seen are red and black too.ever seen grey and black from CN5 to the Tyco plug
AH I get it now, I thought you meant internal wiresNot all Ian, you're right, all the one's I've seen are red and black too.
I was just suggesting that the OP uses a 5 core cable to wire the power and CN5 connections all in the one cable from the boiler to the hive receiver to keep it tidy. The 5 core are invariably, Brown, Blue, G/Y, Grey and Black. So I always disconnect the plug cables and then use the Brown and Blue as normal for power from boiler to receiver and then the Grey and Back from CN5 > 1+3 for the switching.
