SunTouch SunStat CommandPLUS WiFi Programmable Touchscreen Thermostat | 500950

SKU: 500950

The SunStat® CommandPlus™ Wi-Fi Programmable Touchscreen Thermostat - All New in Aug 2023 and available now.

This beautiful all-in-one thermostat is the latest innovation from SunTouch to control all 120 or 240 VAC floor heating systems, via its glass touch screen or Watts Home app (No Voice control like the ConnectPlus)

The CommandPlus brings you the latest designer look, new features, and Wi-Fi control at the Same price as the Command, which is the best-selling SunTocuh thermostat in history.

Floor sensor wire included, 15 Ft long.

And, the CommandPlus is not just another pretty face - it's smart, safe, and easy to use. The Guided setup lets you easily activate a schedule for floor heating comfort to suit your lifestyle via the Watts Home mobile app or Voice commands.

Energy-saving features such as warm weather shutdown and temperature compensation are standard, and 

The CommandPlus controls a single zone of electric floor heat and includes a built-in GFCI for safety. Achieve the best results by setting it to control the floor temperature using the included 15 Ft sensor wire and, optionally limit the floor temperature or configure it to control the space through air temperature alone. The most options for control in the industry.

•  Easy to use scheduling - comprehensive menus & help screens plus the app

•  Control up to 1800 Watts of Floor Heat @ 120v - And 3600 Watts @ 240v (Thats 150 or 300 SF @ 12/Watts/SF)

•  Designer Black Front Display - high-resolution large touchscreen shows Floor temp, or Optional Weather and Clock displays; the thermostat is white on the sides to blend with most walls. It is only available in this color.

•  Thin profile on the wall - Big enough for easy use, but unobtrusive

•  Guided Setup  - Makes installation simple

•  Energy Use Monitoring - shows total hours of operation - see how little energy floor heat uses.

 Outdoor Temperature & Weather display options

 Floor or air-sensing temperature control

•  The most safety options - GFCI Built-in, Overcurrent, Voltage-level sensing and Remote software updates

 Use Wired SunStat Relays to control additional areas - Wired connection to SunStat 500980 R4 Relay(s) - The PLUS is also backward-compatible with Older Relay 3 models (500880 wired only), so there is no need to replace older R3 relays if you want to change an existing thermostat Gen3 model (500825,500850, or 500875)

•  Home Automation Tie-In via dry contact (allows thermostat to be turned on/off by a home automation system)
•  3 year manufacturer warranty

Install Steps

Pull power supply wiring to the control location.

  • Leave about 6 to 8" (15 to 20 cm) of wire for connections.

  • This wiring should be size 12 or 14 AWG, in compliance with local code requirements.

  • A qualified person should run a dedicated circuit (ideal) from the main circuit breaker panel to the control location. If a dedicated circuit is not possible, it is acceptable to tap into an existing circuit. However, there must be enough capacity to handle the load (amps) of the floor heating system being installed, and any appliance likely to be used on the circuit such as a hairdryer or vacuum cleaner.

  • Always avoid circuits that have ballasted lighting, motors, exhaust fans, or hot tub pumps to reduce the likelihood of interference.

  • The circuit breaker should be rated 20 amps for total circuit loads up to 15 amps. A 15-amp circuit breaker may be used for total circuit loads up to 12 amps.

  • A GFCI (ground-fault circuit interrupter) or AFCI (arc-fault circuit interrupter) type circuit breaker may be used, but is not necessary.

Materials Required

  • Electrical box (must be UL listed and proper size)

    • Portrait: vertical 1-gang box (For multiple heating elements use a 2-gang (4x4) box with single-gang mud ring)

    • Landscape: square 2-gang box/plastic 1-gang mud ring

  • Conduit, flexible or rigid (if required, must be UL listed and proper size)

  • Electrical wiring cable (UL listed)

  • Minimum 14 AWG to 12 A / 12 AWG to 15 A

It's a replacement for my original one. Easy to install and program. I like the sleek design and the ability to change the color of the background lighting. It also works as nice nightlight.
Smooth Transaction.....No problems
Review by
I ordered my SunStat in early November. The customer support rep was very helpful in choosing the appropriate model since my previous one was no longer manufactured. All went well and I received my product within a few days. Installation was seamless. Thanks!
does not warm floor - lack of support
Review by
after replacing older model which display no longer worked, installed this one - display now fine but not warm floor when says"warming" - warmyourfloor said call suntouch, suntouch cannot recommend anyone to troubleshoot, most electricians I called said they don't work on floors, had to convince one that it was only the thermostat I was interested in, the problem is as yet undiagnosed...
Quality product and easy to install.

I bought this programmable T-stat as a replacement for one that failed. The product was shipped in a timely manner and was as advertised. It is a quality product and was easy to install.
Easy to use
Review by
I had a contractor install this along with my SunTouch floor mat under the bathroom tile. It was his first time installing a heating system. He hooked up the wiring wrong and it didn't work. I thought maybe he had installed it wrong or damaged the sensor. I asked my son in law to look at it and he rewired it and had it working in 5 minutes. So I don't know if it is really difficult to wire but I do have a smart son in law. It is easy to use and has a nice display. It does take a while to warm up though.
Easy to Install and Program
Review by
This is a very nice thermostat that's simple to install and program. Don't be afraid to do it yourself, I did the entire job from mat installation to wiring up the system, it was easy with the excellent directions provided with the equipment. Glad I did it, saved a bunch of money after finding out that all my "qualified contractor" was going to do was to read the directions!!
So far, so good
Review by
First unit lasted 10 years or so without a second thought, then all of a sudden it failed.
This unit was a direct replacement, installed per instructions in about 20 minutes.
The only complaint I might have is that the display is very bright and displays the temperature in a huge font. I wish it had the same size font for date/time as well, it'd serve as a wall clock.
Otherwise, no complaints at all. Ask me again in 10 years, hopefully it'll last as long as the original.
Works like a charm. Very attractive LED. User friendly.

The original Sunstat View thermostat was poorly designed and failed within a year. The Sunstat Command is a much better design, was easy to program and our floor is warm again.

Easy installation and setup.

Neighborhood electricians were all booked, so I installed it myself. Only problem being the mounting screws were too short so I used the old ones.
Setup software was very good.
