Just been looking at the CH Controls and Zoning section - which
discusses the various heating 'plans'. For each plan - Y-Plan,
C-Plan, S-Plan, W-Plan etc., there is a link to a description on the
Honeywell site. . . . except that Honeywell have taken down that
very interesting
reference document, and you you now get re-directed their home page -
which isn't very useful!

Anyone know of an alternative source of these plan descriptions,
which could be linked to, instead of the 'dead' ones?

Salus do good clear diagrams

Yes, they'd probably do for S-Plan and Y-Plan even though they're not
quite the same as the original Honeywell ones. Interestingly the
combined one which you cite uses 16-way wiring centres, whereas the
individual ones use 10-way boxes, more like Honeywell.

However, neither covers C-Plan or W-Plan.


PS Roger you remember the Y Plan timer overrun problem you helped me
with a few weks ago? I had to set the overrun timer to 7 minutes in
the end. WB technical informed me that the 24Ri overrun is just a 3
minute timer overrun. I may have more questions about that install if
you are still prepared to help.

I'll do my best! What led you to the 7 minute setting - what actually
happened if you set it to less?

OK, I've redrawn these plans in Autocad. If someone wants to put them up
on the Wiki they're welcome. Please let me know what format/size you
want them and where to send them.

Here's a sample: -
