Vaillant AquaPlus 362-7 & Hive Heating

[ADurr]

Yup, it's on, and in the mode that would normally await signal from the stat to turn heat on

I.e. no programmer interfering and not in "moon" setting as Valliant have it

I did switch the grey wire back to Term 2 and tried it like that and the boiler kicked in and permanently on

It could be wrong but might not be that. Try the grey in L and Black in N remove the brown and leave in a terminal strip connector if possible. Do you have any test equipment?

Multimeter in my father in laws van so don't have it to hand right now.
I'll dig out a terminal block and try what you said.
One point I did see is that the grey wire has a brown floating bit of sheath, bit like the earth sheathing but solid brown. Whether that's anything relevant don't know

Yes, that’s how it should be, indicating it’s a switch live wire, but it could be wired as permanent live grey and switch brown, as that would have still worked on the Honeywell.

So any ideas on where to put brown if I wire as Black N, Grey L

Yes it would be where the grey was, so heating on (3).

Tried that kicks heating on but no light on reciever still

Could be a duff receiver?

No idea, is there a way to test it? I've rewired it back to old thermostat now as the Mrs says it's freezing in the house lol.

Balls, was hoping this would be an easy one.

 

[CBW]

Don’t think there’s a way to test the receiver, only thing you could test is the power going to it.

Confusing. I'll check if I can see whats plugged in where on the pcb on the boiler, but the main lead from a fused switch on wall is the only cable into the boiler, whether I can see where it goes after I'll check.

Bugging me!

Honeywell t40 to hive

First post. I'm hoping to switch from my old Honeywell t40 to a single channel hive for my combi boiler, Worcester green Star 24i. I've read many threads but I just wanted to double-check that it's a straight swap and I don't need a linking cable. The cables go earth, black, light grey and...

Wondering if this is the same issue?

However even with the timer on "call for heat", unless there is a stat demand it wouldn't kick in?

My boiler is currently on the sun symbol which means when I click the stat over the current room temp I get heating on.
