Hi All,

Apologies if something similar has been previously posted but can't seem to find anything.

Looking to fit a Lyric T6R thermostat to a Worcester Greenstar i. Just looking to get some clarification on what should be wired where really. The receiver box needs to be connected to boiler and wanted to check the below:

230v out from boiler goes to receiver box (L + N)
T1 & T2 on Honeywell wiring diagram relate to LR & LR on the boilers electrical diagram.

If you could advise on this and if you have any extra information that would help please let me know.

Cheers.

I think you mean Ls and Lr.

Connect A to Ls, and B to Lr. (You should use heat-proof cable for connections to the boiler.)

Cheers for the reply.

It shows on the boiler wiring diagram as LR & LR. I assume one of them is LS?

Thanks for the help!
