I'm replacing my multi-zone Danfoss controllers with Hive, so far the downstairs Hive receiver is wired in and working well. I'm having a problem wiring in the Hive Single Channel receiver to replace a Danfoss TP 4000 for the upstairs zone.

The TP 4000 is battery powered and has 2 connected wires to COM and N/O please see attached image.

Hive wiring diagram attached for your information

I'm believe that I need to
  1. connect the brown COM cable to pin 1 on the Hive and create a bridging cable from 1 to L
  2. connect the black N/O cable to pin 3
  3. connect the spare grey to N
The problem I have is that the grey is not currently connected to anything at the other end, I've done a continuity check and traced the wire back to the main terminal, but I don't have any idea where to connect it.

Any help would be great! If you need any more info please ask.

Take the com to L on Hive and link to common at hive (terminal 1), the black wire goes to 3 and connect the grey to N at Hive and find a permanent neutral at the wiring center and connect the other end of grey there.
