Hive not switching heating on

[drewdrew]

Have just changed a BDR91 receiver to a hive single channel one on a combi boiler, the wiring for the old receiver is attached as are the hive instructions how they should be, have wired up as follows

BDR N to Hive N
BDR L to Hive L
BRD A to Hive 1
BDR B to Hive 3

The reciever turns on when I switch the power back on however the hive receiver does not switch the heating on when asked, it just us not firing the central heating at all was just wondering if anyone had any advice?

You will need to take a live feed from L to common.
Then connect up to number 3.
