i have now managed to pair the HCW80 with the HC60NG - but the ST9400C is still not turning the boiler on - it appears the boiler tries to turn on and then turns itself off immediately

Hello, this is less like a simple question and a lot more like an electrical engineering project.

However if you can post a diagram of what you have done here I can take a look at it for you.

We can go from there.
