Wire up a temp controlled circulation pump.

[Stella]

Hi.
I'm wanting to connect a temp controlled unit that will turn on and off a hot water pump.
Can't weigh up how to do it as the wiring diagram doesn't make any sense to me.
Thank you.

Do you have anymore information is the hot water pump for a heating or cooling operation

It's for heating, I did forget to mention we are in Bulgaria.
Basically we have a log fire that is used to heat radiators, the pump is powered by plug in box. The idea of the thermo switch is so we can leave the box turned on all the time and when we light the fire the water start to get hot it will turn the pump on at a set temp and shut the pump off at that temp.

Live in on 1 and live out to the pump from 3 there will be a slight differential on switching temperatures

If I put my tester on to show a complete circuit its the op way round on. Will turn the pump off when gets to temp and vice versa.
Thanks Steve
