Drayton wiser kit 2 please help

[midstay]

So I bought the Drayton wiser kit 2, but I don't need to use the hot water channel.
Which wire would I put into the Drayton wiser

The Wiser kit 2 seems to refer to what is in the kit, not how wired, there are three wiring diagrams, seems you need the One Channel version, can you confirm that is the version you have?

The Salus thermostat, likely brown is line, blue is neutral and gray (com) goes to one on single channel, and black goes to three, on single channel, but if not a single channel version this could damage the boiler.

In the main, thermostats have a diagram somewhere on them, or a name or number to identify them. That info would allow readers to look for the manual, I have had to guess what it does to some extent when no info given.

Can I just use the kit 2 without using the hot water
It's salus rt500

I would say so, transfer the L’s and N’s and then NO (black) to terminal 4. I don’t know why you bought the 2 channel but hopefully you can use it.

Sorry can you tell me what colour wire goes in to the Drayton wiser please

No, as step one is finding out if low voltage or extra low voltage control. If extra low voltage then can't combine supply and control, one is 230 VAC and the other, like 24 volts, could be DC. If all low voltage (230 VAC) then one may be able to combine, but it depends on protection, combining could result in bypassing a fuse in the boiler, so not straight forward.

It may be that you can use the dual channel, but can't work that out remote from the job, it needs some inspection and testing to work out.

Thanks for reply,
Do you need me to take pictures of anything that would help you?

Other end of the white wire

this 5 core seems to be both supply to boiler and control for boiler, in theory one should not mix extra low voltage and low voltage cores in the same cable, so it is very likely low voltage, but need to confirm it is low voltage.

Note low voltage international standards organisation = 50 to 1000 volts AC, think DC 75 to 1500 volts, but it seems manufacturers realise the in Europe we can use some common sense and in the USA they call what is officially extra low voltage, low voltage so often labelled for the USA market, do be careful.

I have connected it and the DW is working on the app, I've left the thermostat downstairs on and on the DW it shows the heating is on but the boiler is not firing. Do I need to disconnect the thermostat. This is the picture of the thermostat

Set to maximum, decommission or link the 2 switch wires

What does that mean? Sorry I don't mean to be rude

You asked about disconnecting it, but that’ll leave a break in the circuit. So you have the option to set it to maximum and the new one takes over, link the 2 wires that make the on/off switching contact or remove altogether (decommission), but you’ll need to complete the circuit in the wiring center.

Thank you for clearing that up, I will get a electrician to do that

No worries, but if you want/need heat in the meantime, set the existing to the maximum temperature and Wiser will take over.

I tried this, it will show on the wiser the heating light is on but won't fire the boiler I can't get around what it could be
