Baxi 830 wiring for honeywell T4R thermostat

[richiemaestro]

9Hi all,

Hopefully someone can help me, I’m wiring a new honeywell T4r receiver into a new Baxi 830 combi

Done some research but can’t the exact information.

Currently have baseplate in and I’m wiring the power from the boiler aswell using (0.75mm) 5 core cable.

The Baxi has 2 terminals I think for SL in and out.

Does the left terminal (black cable) on the boiler "T1" (live in) go into "A" on the receiver?

If so, this should mean that "T2" (grey wire) leads to "B" on the receiver?

Thanks in advance ☺

I would say the other way, but doesn’t really matter as it’s just a switch

Thanks CBW!

Out of interest, why the other way around?

Because the Live in is the live return on the boiler, but like I said, doesn’t really matter.

So black cable "T1" to B and grey "T2" to A?

Either way.
