Relay help much appreciated.

Evening sparks... i'm a relay virgin and need your help.

First one I need a 12v thermostat to bring a 230v pump on... am I right in saying that in a relay your L & N from fuse spur in the top side, a L & N in the bottom side (output) then an 'a1 + a2' which would be my closed contacts from my 12v stat? What is it I need to ask for in the wholesalers please?

Next one... building inspector said he wants a heater (2kw) coming on with the light in the bathroom. Never heard of this regulation before but its on a granny annex I'm currently wiring. Anyway... so similar to the above relay but the time I'm going to have a 230v signal into some sort of relay to pull the contacts together for the heater? Again what sort of device should I be asking for at the counter.

Muchas Grasias.

Has the stat got a 12v output or is it volt free? Also is it ac or dc?

I'm having a bit of difficulty deciphering exactly what you're asking for, do you mean one of these?
Buy Interface Relay Modules INTERFACE RELAY 2RT FASTON Finder 4C52 9048 0050 online from RS for next day delivery.

Why has the building inspector requested a 2kw heater to come on with the light? Just use a contactor of suitable rating?

Regards

Billy

12V relay please, with 2 X NO contacts rated to the pump, whatever that may be. Also could I have a 230V relay with 20A contacts (would be nice but would settle for less) oh and can you make that 2 X NO as well. Oh and by the way a nice box to put them in and a couple of bases to go with the relays. Some stuffing glands for the box and several metres of white 1.5sqmm flex. Oh and I forgot, how much is that damaged TP board going for in the corner....... - that's usually how my conversations go.
