Customer Rating For Touchscreen Programmable Thermostat

Simple to follow instructions Reinstalling the cables into the wall was the most difficult step. After the first unit lasted nine years, this was the first replacement.

Obviously, my floor tile heating system stopped functioning. I carried out all the examinations that showed the thermostat was the source of my issue. I was hesitant to get a new thermostat after learning that floor thermostats had a finite lifespan. I made a choice that I don’t look back on. I got back to my heated tile. I had forgotten how wonderful it felt to enter the restroom in the cold and land on a warm floor. Although I have no idea how long this thermostat will survive, it was unquestionably an improvement over my 8-year-old unit. It was simple to install, program, change, and view the current floor temperature thanks to the instructions.

Our original thermostat had only been in use for 12 years when it broke. It was replaced in 2016 after being discontinued in 2014. The replacement for the replacement was obtained. The original thermostat hooked directly into a wire harness and had a male connection on the rear. We had anticipated the replacement would work with the plug.

Not at all. We made an electrician appointment, and $249 later, everything was working again.

The $249 looked excessive, but the 30-minute service took over three hours to complete due to how the sensor wire was initially attached, causing it to fall back into the wall. In any case, the installation went smoothly and setting up and operating the thermostat was simple.
