From here is get´s a tiny bit more complicated

1. Connect all the blue´s together (from the plug, the heatingbands and the the switch)

2. Connect all the yellow/green wire´s from the plug and the heating band

3. Connect the brown wire from the plug to the the numbers 1 of the SSR´s

4. Connect the brown wire´s from the heating elements to the number 2 input´s of the SSR´s

Hi
Many thanks for the help. I am nearly there. Its awesome. Just a quick question on the fuse amps and the switch amps. Will a 3 amp standard domestic plug and fuse do?

Hi
I also forgot. I have 2 x 150 watt heaters and 2 x 200 watt heaters. My heating bands also have no ground wire. And also no indication of positive or neutral. Does it matter?
Thanks so much for the help

Hi,

Glad to hear it’s useful 🙂

On the fuse, I think you need a bigger fuse, 5 or 10 amps

It’s not a problem the heaterbands don’t have a ground wire, less to worry about.
I don’t think the polarity matters with the heating bands, and otherwise just test it.

Hi jerzeek
I think I am nearly there!
I got a bit confused with the switch and power to it but I think it’s good now.
Could you gave a look?
Also I added an earth to each heater band. Is it OK.

I assume the black wire is the wire with the plug on the end.

That almost looks good, there is only a small error at the switch, the blue ones from the PID controller should be separate from the blue one from the plug (see picture down) ( it wasn’t clear from my previous pictures 😉 )
The blue´s from the heaterbands are good

most of the rest looks good, only 1 connection looks a bit flimsy, make sure all connections are sturdy cause a lot of power will go through them.

Have fun with the machine man!
