Wiring honeywell DT 90 thermostat to Baxi combi 28 HE boiler

Lucasdemoley · 30 Mar 2011

HI,

I've bought a Honeywell DT 90 thermostat as recomended to me in another thread. Looking at the wiring diagrams (below), it seems that all I need to do is wire the BK2 on the boiler to 'A' on the thermostat, and then BK1 to 'B' on the thermostat. Am I correct, or was I about to get it all wrong?

Advice really appricated.
