Hi there

Is someone able to confirm that the following wiring mapping is correct to change from Honeywell R6660D to Hive Active Heating Thermostat - 4632 J - on a combi boiler (Worcester Bosch Greenstar 28i Junior), or advise otherwise.

N to N
L to L
A to 1
B to 3

I have attached a pics of the current R6660D wiring set up. The mains power cable from the mains fused switch goes into the boiler, hence only one cable (from boiler) into the R6660D receiver.

Many thanks

Assuming that you have the Single Channel version of the Hive (I think that's the 4632J) it sounds spot on to me.
