Glow worm 18hxi wiring help.

Hi, I have the above boiler, ep2002 programmer, three port valve, three wire room stat, tank stat, and pump. I have had to rewire the wiring centre as the spaghetti and chocolate block nightmare that was housed in a single socket enclosure, was pulled out of the wall by accident (ironing board). I have assumed it's a Y system (please correct me if I'm wrong,) I can't make the system run however as I can't figure out what I should be doing with the switched live and pumped live connected to the boiler. Please can someone with more electrical nous than me, send me in the right direction. Thanks.

Y plan. Switched live to the boiler, and pump live connected to the boiler pump terminal not to the switched live.

Thanks, but where is The switched live coming from, I'm assuming the room stat/3 port valve White wire?

Thanks, that's how I've wired it, but the pump live from the boiler does not show a voltage when calling for heat or water.

There will be a connection in the wiring centre as on the hxi it has its own pump connection get a sparky to sort out will be best thing

You having a laugh??
Sparky to sort out controls wiring???
Very few and far between.

Am I correct in assuming that the pump live should give 240v when calling for heat?. In order to let the pump run on after the boiler switches off. I'm wondering if it's fused in the boiler and I've blown it somehow? Have connected the pump to the switched live for now, so that it shuts the pump off immediately the boiler stops. Is that a problem?

Employ the services of someone who knows what they are doing.
If you've damaged the control board due to incompetence then you deserve all you get.
