Wiring boiler control

[Nutmeg77]

Hi All,

I'm trying to wire a SP Connect to a Valliant ecoTec pro 24 boiler.

I've found this but not sure how to wire the heating and water (if needed) to the boiler

Here's the Connect

Here's what I'm thinking:

Connect - 230 L & N to Boiler L & N mains connection (X1)

Connect (if neeeded) - C0M 2 to Boiler L mains connection (X1)

Connect - COM 1 to Boiler L mains connection (X1)

Conneect NO 3 to Boiler RT 230 V AC room thermostat (X1)

Do I keep the bridge on 24 V DC room thermostat (X100) or remove it??

Thanks for any help!!

Any work carried out on that particular boiler will need 26.9 safety checks carrying out.

Hi Chris,

Yeah I know. The front cover is also the room saftey seal. I contacted SP for help and all I got from them is, you will have to pay for our engineer to come out and do it. Loads of help!! They wouldn't even supply a wiring guide for the controller. We got the heating side working but not the water. It will be tested, I have a GS engineer to replace the cover and test once we get the controller working properly.

Thanks.

It’s a combi boiler, so hot water on demand.
