Temperature sensor used with floor heating system and thermostat.
The thermostat comes with one sensor wire. This is if you would like to purchase an additional or replacement sensor wire.
For peace of mind consider installing an additional sensor wire. In the rare occasion the floor sensor fails, you will have a back-up sensor wire installed ready to be connected to the thermostat.
The temperature sensor should be located inbetween two heating elements, at least 6" from the edge of the heated area.

No reason to doubt quality
It's hard to write an objective review of a sensor like this that you hope will last many many years. So far so good. The wires/shielding could have been a bit more robust, but this *should* not matter.. I put two in the floor so there's a lower likelihood of a failed warming system due to a bad sensor. It looked to be of fine quality to be embedded in thinset and forgotten about, and tested very similar ohm readings to the other sensor sent with the kit. Came with a very long cable with the label stuck to the end of it. I wish the label were customer-attached, (or a second label available) so you could have a good readable label after fishing through conduit and cutting the length to fit.
It's my back up floor sensor
Good price so I installed 2 just incase one should go out. Better safe then tear up floor to put in a new one if the first one goes out.
Replacement after NIB didn't ohm out
This item was sent to me under warranty. The New in box sensor that came with the kit did not have continuity. 1 call to the warming systems and they sent out the replacement right away. The replacement sensor tested properly and we finished our tile install. Have to wait a few months to turn it on. Should be good for the Chicago winter. Thanks
