What is a suitable/recommended cable for OpenTherm?

by Vlado Menkovski   Last Updated September 23, 2018 18:21 PM

I have the Nest HeatLink connected to the boiler via OpenTherm. I need to move the HeatLink due to wireless connection problems with the thermostat.

The Wikipedia page for OpenTherm states that I can use a cable up to 50m with 2x5 ohm resistance. Not sure how to translate that into a specific decision for a type of cable.

Does anyone have more information on what would be a good cable for this application?
