Help wiring Honeywell CMT927 roomstat into Combi boiler

[UNG]

If you follow diagram B in the stat instructions for wiring the receiver then it will work as required in your original post

Iv found the confusion.

The link I attached shows a different Reciever unit to that I actually have in front of me.

My link is for an R6660D

The receiver unit they have supplied me is a BDR91

The BDR91 has an extra L bank

Diagram b in that link is what they have supplied with my 927 stat

Hopefully me rambling on about 2 L make sence now?

 

[thomo2710]

Do I just leave the middle L empty and put the spur/boiler N into reciever N and the spur/boiler L into the right hand side L on receiver?

there both live terminals at the receiver, it doesnt matter
