Would RecommendWorks as advertised. I only needed 3 wires, but it doesn't hurt to have extra conductors for any future changes.

Great 4 to 5 wire replacement for smart thermostat
Would RecommendI need to replace my thermostat wire from 4 wire to 5 wire, in order to supply a dedicated C wire for my smart thermostat upgrade. My particular furnace didn't work with a C wire adapter, so converting to 5 wire was my only option. This 5 wire cable had adequate sheathing that allowed for an easy pull through the walls of our house. It was conveniently mounted on a spool, which allowed a tangle free pull. The replacement went much easier than expected.

CABLE for a thermostat.
Would RecommendI was looking for a cable to install a thermostat. Would you believe this thermostat wire is what I needed? It matched exactly what I was looking for. Copper conductors, with a coating over each wire, are wrapped in another jacket. Amazing.
