    Hi, need a little help with the heatlink install, read some previous posts but I have a slightly different wiring. On the Honeywell the second L is used. So I have:
    N L L A B (C not used)
    Do I just ignore the second L connection and connect N L 2 3? or do i also wire it to the heatlink L?



    thanks

    The two L terminals are linked together inside the BDR91, so effectively they are the same terminal. Whatever is in both them would go to the single L terminal at the Nest Heatlink.

    The wire in the BDR91 A goes to the Heatlink 2

    The wire in the BDR91 B goes to the Heatlink 3

    Connect the Neutral to N
