I think most epoxies would do it - the temperature on mine is only about 35C which I think is typical but if it's higher you might need to think again. The resistance of the wire won;t matter much whichever way around you do it - I suggest you place the box somewhere convenient so that you can twiddle the knob to fine tune the sensitivity and adjust one or both wires to suit. If you want more noise Maplin sell a really loud screetcher (I've got one on my gas alarm) so you could use that.

The temp doesn't get very hot under normal conditions, and if it goes over 95 degrees or so your alarm will sound anyway. Much quicker than epoxy and easier too, although arguably not as elegant in engineering terms. Mine's been in 2 years now and no problems.
I found jubilee clips clamp with too much force.

It's a neat looking kit but beware - the clever bits of it have a large number of tags very close together. Soldering them without making accidental bridges between them is going to be a real challenge!

My kit has just arrived in the post - I am like a school boy unpacking his Airfix model!

David, I dont have the PBO article but I know the kit youve used as I use one for my fridge thermostat. My electronics knowledge is very rusty so .. Did you just change the value of R4 to reset for a higher temperature range? Id guess changing R4 to 25K would reset the range for between 30 and 70 degrees ?
