I currently have a British Gas Wireless system and am now upgrading to a Lightwaverf system with matching TRV's.

I am slightly confused so am seeking confirmation on the connections.

The WR1 has 6 connections Labeled N L 1 2 3 4

Live Neutral and Earth are obvious. I then have a link from Live to 1 this I believe to be COMMON

3 is my call to heat and is Grey.

My Lightwaverf has 8 connections Earth N L L NO Com NC P

NO = Normally Open
NC = Normally Closed

Again Earth L N are straight forward ..

I believe I have to link from the Live to Com.

Now would the Grey wire now go to NO or NC ??.

Thanks in Advance Guys

Normally Open will become live when it calls for heat.
