Satchwell Sunvic replacement?

adenough · 27 Oct 2023

I'm looking to replace this controller with something more modern or a Drayton SM2. System works perfectly but plastics cracked.I cant find a Satchwell at a realistic price. Any advice would be appreciated. Thanks.

Looks like a twin channel programmer, several to choose from, take your pick.

I've bought a 2 phase universall controller. The wiring doesn't relate toy old Sunvic. I'll attach pics of the S system of the new one and of the sunvic. Any advice on how I can overcome this would be welcome. Thanks.

1 = N - should be self explanatory
2 = L - should be self explanatory
4 = Heating on would go to number 4
7 = Hot water on would go to number 3
You don’t need links in the new one, so discard.
