Hi pretty new to this forum so bare with me.
I've fitted these before but only on combi boilers and now I need to fit one on a separate hot water and heating system.
It's the salus it-500 and I have attached my wiring scheme. Just need to know which one goes where on the salus it500 if you are familiar with the set up of them.
Thanks
Peter

Thanks so do you mean scheme C ?

Can you say from my wiring which wire goes to which... Eg. 1 goes in to C etc

Obviously I get where L and N go. But you have NO and COM and just need to know which wire number on my current setup goes where?

Thanks

yes done the wire colours if you see my pic
 
Shaun, all of your pics state for Combi boilers, yet OP states it’s not for Combi boilers and for conventional system. My understanding is if it’s the same wiring setup then it should clip onto industry standard backplate?
 
C diagram on my pic if you look I’ve put the correct colours in the correct terminals for you see the red yellow and blue lines

Can’t no one see them ???

Yes I can see them, didn’t know you had put them in 😳 it just the wording above states for Combi boiler, didn’t know it was the same for standard systems as well - always learning 😀

Yea I see it now I think I wasn't looking properly

Ok thanks for this I'll give it a whirl

Is it ok to out the two live and two neutral in to the same one also as it is on my original images?

I note image c is for 2 zone central heating systems so does that account for the separate hot water in the upstairs tanks etc


Thanks

This is what is upstairs and think there is hot water tank in attic also or water tank of sorts that's feeds CH?

They should fit

Ok cool thanks

You're not in North Wales by any chance in case this goes horribly wrong!

So use the same wiring that you sent me above and that will work with the hot water and central heating?

Im gonna go for it if you think it's good to go with 🙂

That is 100% NOT the case with the device in question ..........
