Hi
I have a 6 year old Worcester Bosch Greenstar 30si LPG Combi Boiler, currently I have a Honeywell T40 thermostat with the Brown Wire going to connector no 3 and Blue Wire going to connector no 1. I have bought a Honeywell Lyric T6 Smart Thermostat. There are 2 parts, first the Reciever Box has an Earth, Live and Neutral, on the installation instructions the 2 wire from the Boiler to the Reciever Box will go to T1 and T2, first of all which wire from the Boiler goes to the Reciever Box?
Then the 2 wires from the Reciver Box are T & T to the Wall Thermostat T & T
Any advices?
Cheers

you dont have a perm l n and earth so cant install it there but to answer your q

a to 1
b to 3
 
Thank you, the Boiler has a Timer / Program panel, so the new thermostat does the same. So I can wire Brown (3) & Blue (1) to B & A respectively to the reciever box. Then I presume the New Honeywell will take over the control of the boiler.
Cheers and Happy Christmas!
 
No it won't

You need a gas safe engy now
