Hello,

We have a wiki page he -

http://wiki.diyfaq.org.uk/index.php?...s_and_Zonin g


with details of the different arrangements for domestic central
heating. I had prepared wiring diagrams for the site and also for
download as a pdf: -

http://www.diyfaq.org.uk/docs/Sundial-Plans-Rev1c.pdf
http://www.diyfaq.org.uk/docs/Sundial-Wiring-Rev1c.pdf

Unfortunately, I made a transcription error in the wiring diagram for
Y-plan which is not obvious and which would cause incorrect operation
of the system if implemented. Fortunately, someone spotted the error
and posted a note on the wiki.

I have now corrected the error in the Y-plan wiring diagram. If you
have previously downloaded the image of the Y-plan wiring diagram or
the pdf's (at Rev 1b), then you should discard them and re-download
the revised items (at Rev 1c). Please pass on to anybody you you may
have emailed the pdf's to.

Thanks to whoever spotted the mistake and to Mr Rumm for updating the
the wiki.


Cheers,
Dave Osborne

Just after printing rev 1b out for laminating as well:-(

An excellent effort despite the earlier small mistake that I missed
despite wiring up quite a few Y plans. Far better than any other
diagrams I have seen

I love the extra page with the internals of the mid position valve

Well done and thank you

Adam

Thanks Adam. Please see my reply to Roger also.
