Extending cable for sensors on 5104DTSI

Hey People
The manual for the 5104DTSI shows that, to a maximum of 25 metres, you should use CAT5e to extend the length of the cable on any of the three sensor types.
Can I assume you pick one pair of twisted cable for this extension, or one cable from each of a couple of pairs?

Thanks

Yes, only need one pair. Doubling up (2 pairs) would not be a problem though. Best to use a pair as opposed to a wire from each pair to maintain twists and simplicity.

Thanks a lot Mr Conformist appreciated.

 

Does anyone have suggestions for wall mounting the sensors discretely or flush with plaster?

Would this be compatible: http://www.tempsensing.com/sensors/1wire-temperature-sensor-flushmnt.php

 

Yes, it should be ok as long as it's using 1-wire parasite power. I only looked quickly at the specs and couldn't see it there.

 

I like the look of those. I wonder if a similar idea could be used to make them with those plastic screw in plaster anchors you see at Bunnings and some sort of press on cap.

Cheers

FYI, I now tested these and they work nicely on the 5104DTSI.
