Hive thermostat installation

[Maheshsam]

Hi Guys,
Can someone help please.
I am trying to wire my hive reciever to the potterton combi boiler. There are 4 wires coming out from my boiler ( L,N,E and a black wire). Manage to wire all of them apart from the black wire. Not sure whether it goes in number 3 or 4?
Thank you.

You have 2 black wires, the live in (common) will go to Com, and the other is the switched live, NO (number 3 on Hive).

Hi CBW,
Thank you very much for your reply. I wired black wire to no 3 on hive, but still central heating not comes on. Any ideas? I attached you a picture below.
Many thanks.

Yes, because you have no wire in the Com (number 1) which I said was one of 2 of the black wires.

I have only one black wire tho? At the moment hot water working fine it's just the central heating. Sorry to be a pain.

This was my old wiring from thermostat n reciever

You appear to have a black wire linked to the programmer via a brown wire and connector block, where has this gone? Have you done away with the programmer?
