Central Heating Electrical Connections

[jdld6970]

Background! I was doing some work in garage and had to move the central connection box for the central heating. Once i had done that i then managed to put a screw through the pump lead leading to lots of fusing when i switched on the heating!!!!! this blew up the control box(Centaurplus c27 Electronic Programme from screwfix) Sadly despite having exhausted my limited knowledge the pump never seems to switch off. The thermostat is a Hortsmann HRT2 Room Stat. There is no cylinder stat. I am pretty sure the attached diagram is how it was before but there is something wrong as i say the pump stay on and never switches off.

I know i am asking a lot but is the wiring diagram below correct? PLEASE!!!!


HOW DO I POST DIAGRAMS???

What boiler do you have?

Is there a hot water cylinder?

Does it have gravity or pumped circulation to the cylinder?

Is there a motorised valve (or two)?
