I have bought a time delay relay to build an overrun into my heating system pump and get it working again (as it is getting cold over here in the Uk now!). It was all going well in the test. I have a live that switches on and off that I wanted to use to control the relay and delay the switching off by 2 mins. When I set it up in a test on my worktop it worked fine - however when I connected it to my heating circuit the relay stayed on all the time...

Here is a link to the relay - I conntect a supply to A1 (live) and A2 (N). I contected the same Live to 15 and my pump to 18 (the delayed output) and the switched live to B1. Connecting nothing to B2...

Any help would be much appreciated...
