Hi all im new on here so go easy on me please..

Today i have bought a Honeywell dt92e thermostat and comes with bdr91 relay box.

My combi boiler is a Baxi 105 he with a manual time clock on and this boiler has never had a stat put on, So if anyone could please help me out with wiring this in everyone says its easy but im only good at wiring car stereos not boilers....

I have got a good lenth of 3 core wire so can make 2 lenths out of this wire as i heard this needs 4 cores to wire up?? If someone could explain or show diagrams id be really greatful thanks all.

BDR90 takes a neutral and live from boiler.

A & B go to 1 & 2

Ok so i got to my wiring today in my boiler and proceded to connect my honeywell signal box all i did was made 2 lenths of wire 2 core.... connected one lenth to the live and neutral on boiler and connected to signal box L and N and then i removed link wire on 1 and 2 on boiler and joined the other 2 core wire to 1 and 2 from boiler to A and B on signal box. This all works ok and switches on off ok so is this safely?? done and wired correctly? hope this makes sense thanks
