Great electric screen thermostat
Easy install. We purchased when our last thermostat was broken off the wall. Had to hardwire with ease. and it works so well. the screen beats the old one with use being easier to do.

Works perfectly. Had an electrician install the unit. Replacement my 7 year old sun touch unit that shot craps. Floor instantly heated. Easy to program.

Seamless Upgrade for Heated Floors
recently replaced my old SunTouch control panel with the SunTouch Command Touchscreen Programmable Thermostat, and I was amazed at how quickly my heated floors were up and running again. Installing the new thermostat was a breeze. The instructions were clear, and within minutes, I had the new unit installed and ready to go. The compatibility between my old system and the new thermostat was impressive. The performance of the SunTouch Command Thermostat was outstanding. Once I turned it on, the heated floors responded immediately. The temperature control was precise, maintaining a consistent level of warmth throughout the day. The programmable settings allowed me to customize the heating schedule to my liking. The touchscreen interface was intuitive and easy to navigate. Even as someone who isn't very tech-savvy, I had no trouble adjusting settings or programming the thermostat. The display was well-organized, making it simple to understand. The design of the thermostat blended well with my home environment. The responsive touchscreen and adequately sized display were notable features, though slightly larger text would have been appreciated for better visibility from a distance. In conclusion, the SunTouch Command Touchscreen Programmable Thermostat breathed new life into my heated floors. Its straightforward installation, accurate performance, and user-friendly interface make it an excellent choice for upgrading your heating control system. If you're looking for an efficient and convenient way to manage the temperature of your heated floors, the SunTouch Command Thermostat is a solid recommendation.

Easy to install and easy to program, with a caveat
I was replacing a prior thermostat from the same company. It had been in for over 6 years and was starting to show it's ages, but after a power surge it would no longer tun on the heat, even when it said it had. I replaced it with this model and found it easy to install and program. The prior version showed both indoor and floor temperature, this one only shows the floor temp, so I miss that a bit. BTW - This is for in-floor heating in my bathroom. The reason I give it four stars rather than five is the limitation on the programming. It has three programable setting, one for weekdays, one for Saturday and one for Sunday. This is fine if you work a standard weekly work shift, but if you have weekdays off and some weekend days on, you can't change the programming for the weekday you are off. This likely isn't an issue for most people, but it's something to know if you have that type of schedule. (the old version had independent setting for every day). The programming itself is pretty easy if you've done something like this before. It gives you four switches per day type. I use two on and two at a temp that won't turn the heat on. They call them on or off or some other naming I forget, but it's the same thing. The first one is ON the next OFF, etc. Since I wanted to have the heat turn OFF at 12:30am, I had to use the first ON setting as an off, which works perfectly well, it's just a little confusing. So on weekdays I set it as follows.. The ON OFF are based on what the system calls it, but not how I use it: 1: OFF (70F) - 12:30am 2: ON (81F) - 8:00am 3: OFF (70F) - 9:00am 4:p ON (81F) 11:30pm Which works fine for me. The display is nice and is easy to read. It all works fine and as I said before, the install was easy as I was replacing an existing setup. I can't comment on how easy a new installation would be. It doesn't have WiFI, which I didn't want anyway. I think the value for money is good. I'm happy to have it installed and my floor heating up again.

This unit replaced an older Suntouch floor controller that stopped working. Reused the existing temperature sensor that was already installed in the flooring. Just had to reconnect the wires, program the settings and it works perfectly. The display is a lot nicer than the old unit.

I bought this item to replace a dead NuHeat thermostat, which never worked properly. Easy to install if you're replacing an older thermostat, just make sure you watch what you're doing: remove one wire from dead thermostat and install in new thermostat, one at a time. I really like the simplicity of this unit, since it is installed in a second home that sees alot of friends using the place, Thus i did not want a complicated, programmable thermostat.

Our older model suddenly stopped working eventhough power was getting through. This is a great replacement and is working great. We were glad the photos showed exactly what it looked like from the back for the hook up as that was how we were sure it was the right one to order.
