Honeywell AC11201 Temperature Sensor for Floor Heating Applications

I have put heated tile floors in both of our bathrooms. The system works well and I bought this on the suggestion of a friend to have a back-up in case one sensor stopped working. If you don't install a back-up sensor, you're going to be screwed if the first sensor dies. I installed this one about six inches away from the other and pulled the wire up the wall so that it is coiled in back of the control box with a note reminding me what it is. A friend of mine who also installed a heated tile floor is kicking himself for not thinking of a back-up sensor. I may never have to use it, but I'm glad it is there just in case.

I needed a replacement sensor for my Laticrete thermostat after the original was damaged in the bathroom remodeling. This looked exactly like the original, down to the wire. The resistance was also the same and changed appropriately when I held the sensor in my hand.Went into the floor very easy and I hope it will work well once the tiling is finished. This time I buried the wires in 20 mm self leveling mortar and will never again use the "recommended" method of thin-setting the tiles right over the wires.

Purchased 2 in case one will go bad, both working 100%! I installed one as a spare in the floor just in case ... :)

Went ahead and added a second temperature sensor to the floor heat system to make sure I had at least one that would work at all times. Great suggestion by installation instructions, but should be included in main package.

I have installed four Honeywell AC11201 Temperature Sensor for Floor Heating Applications, two each (one hooked-up, one backup) in two bathrooms, and all four have functioned as they should. When installing, they all tested at around 11kOhms and no problems with them being messed-up by the install.The AC11201 installs nicely into a Ditra-Heat system. The thermistor will push down between the plastic knobs on the Ditra-Heat, and dabs of hot-melt glue will hold the wire and thermistor in place while your scratch coat or tile is being placed.

This item was installed as a backup probe in case the primary temperature sensor fails. Since the primary sensor stills works, I can only hope that one will work when and if needed. It did test out properly before installation.

Unfortunately this electric floor sensor doesn't work with the Thermostat I purchased. The Honeywell TL8230A1003.Even though Amazon stated it was often purchased with the T-Stat I bought, it wasnt too clear to me that the Honeywell AC112-01 sensor worked with it.The Honeywell TL8230A1003 T-Stat is an Ambient (air) Temp Thermostat. Which i am going to keep, because the T-Stat which receives the Floor sensor wiring costs a lot more, and ultimately I just want the floor on and heating itself and the room.So sunk this into my floor for nothing.

I ordered this as a backup sensor for my NuHeat floor mat and thermostat. Looked the same as the NuHeat sensor in the pictures and a multimeter confirmed that it works the same when I received it. Cost a whole lot less than the sensor that's branded NuHeat. Very cheap insurance in case your primary sensor fails!
