Landlord thermostats?

You could try contacting Canford Audio or Van Damme cables, they may have something appropriate that's suitable for external use.

Thanks, I recon this should do it:

CANFORD FST-HD - FOIL SCREENED STRANDED CONDUCTOR TWIN CABLE Heavy duty

This D'n'A series (Digital and Analogue) cable is designed to be suitable for both digital and analogue audio signals, with an impedance of 100 ohms which has been proven to be suitable for AES/EBU…

The sensor will only be a thermistor - a resistor that changes value with temperature, so it doesn't require anything too sophisticated in the way of cabling. Any screened two core will do, and I doubt there would be many problems if it wasn't screened.

Same as UFH floor sensors? I did wonder if that would be the case. The resistance of these is measure in thousands of ohms, so presumably the resistance of the cable, a couple of ohms isn't really important?

That was the one I'd looked at too

They also have this, but it's double the price:

CANFORD HST-R - HELICAL SCREENED STRANDED CONDUCTOR TWIN CABLE Ruggedised

This is the same construction cable as standard HST, but with a matt black polyurethane jacket – incredibly tough and resilient, and remains flexible in sub-zero arctic conditions. Ideal for on-stage…

From memory the resistance is 10k at 25degrees, so cable resistance is indeed irrelevant!

just looked it up - see below!
