Customer Reviews

Rated 3.3 out of 5 by 4 reviewers.
Rated 4.0 out of 5.0 by Excellent floor heat controller The two piece assembly (front controls remove) fits into a standard 1 gang wall box. This model can either control air temperature or floor temperature. It also can have minimums and maximums on the floor temperature provided the floor temperature probe was installed with the floor. This unit replaced the previous which lasted for 12 years. The GFI gave out on the old one. We live in an area where wind knocks out power in winter storms and glitches have clobbered two other GFI's in the house over the last few years. So I don't blame the unit for that failure. We use this in the master bath where we have a beautiful marble floor which can be really cold in the winter when the power is out. May 19, 2015
Rated 4.0 out of 5.0 by Simple and easy The unit was easy to install with very clear directions. Programming is a breeze and it functions as expected. The only negative is the display is rather dim, you can hit a button to illuminate it but if your walking by it takes more than just a glance to see the temperature. You can set it to either control the floor temp or the ambient (it also limits the floor temp in this mode). All in all it does exactly what is needed. January 27, 2015
Rated 4.0 out of 5.0 by Easy to Use, Easy to progran Very easy to use and easy to program floor warming control. I use this with my Warmly Yours 120V heating floor pad. This control is very reliable and is great for the fall weather in NY and to program so it is not running all day. I set it 15 mins before i usually wake up in the AM to shower. Has a lightened display for easy use in the dark. Warmly yours is the only product i have seen for use of heated floors. A true industry leader. October 21, 2014
Rated 1.0 out of 5.0 by bummer it was installed in my home by contractor-functioned okay for perhaps 2 weeks-the manueal was left behind so on the weekend it went off & I tried to reprogram it but it would not stay on-I went on line & was given some advice about holding on to the buttons believe me I tried every combination on that manual-it would work sometimes for a couple of hours-making the floors tepid & then it just quit working altogether. it worked ofr maybe 6 weeks at most counts all the hours.
