brand new honeywell 3 port valve not closing heating port

[seco services]

where in essex ?

what programmer have you got ?
when you say hw/heat on do you get any heat to rads ?
can't see how rads are heating without the white wire connected to anything.

I'm in upminster , white wire is connected at mo but not as wiring diagram shows programmer is siemens rwb29. All rads do get hot but with only hw on 2 rads get hot too. That's why I think it's wired wrong valve not closing properly.

white wire is connected at mo

i thought the white was was on its own in terminal 5 ?

 

[ducatinev]

It would have been if would have tried to rewire it myself.

 

[seco services]

so whats the white connected to now ?
as it can't be the room stat as thats wired to ch on/ch off.
sounds like you have no control over heating on/off only by the programmer.

when hw on only how far along from 3 port to rads does the pipe get hot ?

Is your radiator upstairs that comes on with hot water ,in the bathroom?
Could it be plumbed (purposefully) into the DHW pri,aries?

 

[oilhead]

or even primaries?

two rads.

 

[ducatinev]

One rad next to hw cylinder 2nd rad downstairs?

 

[seco services]

if you close a valve on one of the hot rads does the other go cold ?

 

[ducatinev]

No don't think so upstairs rad get luke warm downstairs rad gets quite hot as if CH was on! Regarding wiring mine doesn't match diagram I downloaded from net. Example shows one wire going to terminal 5 in danfoss junction box but mines in 8?
Think I'm going to bite the bullet and get someone to completely rewire it from scratch.

 

[seco services]

can you show me a link to that diagram ?

yours sounds like you only have an issue with the white wire.

2 wires to term 5.

they don't have to follow the exact positioning just helps anyone else in the future working on system.

did you see what your white wire was connected to cause its not your wireless stat ?

No to be honest I'm sick of taking it apart going to get some one in.
Thanks for your help
