Hello,

I have an old-style Y-plan system; HW and CH can run independently from
each other. I would like to replace my Sangamo 410 CH programmer with a
7-day one, like this:

Is this a straighforward replacement? I don't have yhe Sangamo
installation manual.

Cheers,

Kostas

It doesn't look like a one for one swap, one has a back box with 8
terminals the other has a back box with 6 terminals. You will have to
work out the wiring to your existing programmer and that required for
the new one and maybe use an intermediate wiring junction box

The old Sangamo has 4&5 connected, so really 7 terminals. It also has off contacts for both HW & CH, one of which isn't needed for Y plan. So it should indeed be a straight swap. The OP does of course need to identify which terminal is which on each device.

Thanks for this and for all the previous answers (the link to the
Sangamo manual is very much appreciated, not that the other replied are
not). I will take a look at the Honeywell manual and see if I can map
one to the other, but this looks like it's beyond my capabilities, as I
did not even manage to understand under what "Form" my set up would be.

You dont need to know what plan your system is, just identify what the terminals are on each contorller. They'll all be marked.

I would think replacement should be reasonably straightforward. I recently
replaced a dead Honeywell programmer with an ST9400C. Doddle. Very minor
changes to wiring and a little bit of carpentry to set it nicely.
FWIW this is probably the most user friendly programmer that I have ever
come across. I've seen a few.
