Hello, advice needed.
I am replacing my Honeywell HC60NG & CM61NG with a Honeywell CM907 but I need some assistance with the electrical connections.
In situ at the moment is a 3A fused switch (See photo) to which the Earth brown and black from the Isar HE30 are connected. The Grey is linked to an extension to form a straight run.
The Black and the Brown then come back out of the 3A fused switch and along with the Grey linked connect into the back of the HC60NG
The Black went to N, The Brown went to L, there was a Red link between the second L and the A, and the Grey linked went to B
I have removed the connections from the HC60NG but need to know how I wire up my New Honeywell CM907
Please see the photos of the electrical connector at the Isar boiler and also the unconnected wires at the switch end.
Any advice appreciated
