The same as you had before should be fine, and as you were happy with it, it seems the logical choice.
The receiver would normally go next to the wiring centre, providing there is a permanent live in it. The straightforwardness of installation is relative to your competence!

Hi
after considering all option I decided to go for EVOHOME got Honeywell evohome Connected Base Pack
so now I need to connect the Wireless relay box BDR91 ,however my current connection is Hortsman universal backplane and has only N, L, 1,2,3,4 connection
The Wireless relay box BDR91 instructions referring to 10 way junction box
So my question where do I connect B (on BDR91) to ?
as room thermostat in downstairs, which has SL,
but I believe SL connects to the zone valve wire ( could be white wire ) usually 5th connection on a 10 way junction box.
In other words I need to find SL, or white wire that connects to zone valve (if I’m correct) behind the Hortsman universal backplane and has only N, L, 1,2,3,4 connection…
