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?

I cannot find it.
I have driven over 800 miles today and so I am a bit knackered.
But my quick reply is , when the pump stopped it seems that the water in the
system was so hot it tried to go up the expansion pipe to the tank in the
loft. Lots of banging noises and the vent pipe got very hot. If I kicked the
pump back on then the vent pipe went cold and the banging stopped.
I still suspect a plumbing problem somewhere. I can take pictures of the
plumbing if it helps.
