glow worm 35c boiler with a honeywell bdr91 smart wireless thermostat

[anthony bainbridge]

hi there,

I currently have a glow worm 35c boiler in my home, i'm trying to fit a BDR91 thermostat.

the wiring diagrams aren't the clearest in the world.

can someone help please?

I have read loads of threads about the Wiring.

do I have a new power source to the thermostat?
my boiler has its own feed.


where do the wires connect into on the boiler.

this is what my boiler is saying.

this is not my bdr91 but am I right on saying blue and brown are from live source and white and black are to the boiler???/


sorry guys any help would be good

For you:
Boiler-BDR
N-N
L-first L
RT-B

In the BDR:
Install small wire link from second L to A

So N from the boiler to bdr and same for L (Into the first L). Link second L and A.
And RT into B.

Is this correct??

yes
