Replacing old Sangamo 401 timer with a drayton tempus 7

Hi Everyone/Anyone

I wonder does anyone know how I should wire the new backplate - the old old has 8 terminla in total the new one has only N &L + 1 to 4.

thanks

you need to identify what the wires are on the old backplate, there will be permanant live in switch live out earths and comman neutrals. It is only a timeswitch and the tempus 7 a two output programmer, 3 is hot water and 4 heating

Picture required.

Would be better in the Electrics forum too.

Do you mean Sangamo 410?

Many thanks to Bab, Londonboy, & D_Hailsham for your replies.

I did find later a post that seem to give me the information.

It was for a Sangamo F4 to Sunvic.

It read

on the sangamo............sunvic

1 = hot water on.............3
2 = hot water off.............1
3 = live ...........................L
4 = neutral......................N
5 = also neutral
6 = there may be a link here to 1, you dont need it
7 = CH off......................2
8 = CH on......................4

Looking at my Sangamo - it did not have any F4 or F1 on the bottom left hand side.

But the 1- 8 terminals did seem to match the wiring diagram on the back of my old Sangamo 401 and the L,N 1,2,3&4 on the Drayton do match the Sunvic.

So I thought I would give that a go this weekend and see how it goes ?
Thanks again for your help


And I will post the results - with picture if it fails.

Thanks again.
