Description

Customizable, easy-to-install floor warming accessories for any room The Schluter-DITRA-HEAT-E-RS1 is a smart thermostat for the Schluter-DITRA-HEAT floor warming system. It features a sleek design with a mirror-finish and third-party integration with popular voice and home assistants to easily include floor warming into your smart home capabilities. DITRA-HEAT-E-RS1 is a smart thermostat used to control the DITRA-HEAT-E-HK heating cables (either 120 V or 240 V). The thermostat features a built-in Class A ground fault circuit interrupter (GFCI) and includes input terminals to connect a 10k floor temperature sensor. Two floor temperature sensors are provided with each DITRA-HEAT-E-HK heating cable box. The DITRA-HEAT-E-RS1 was designed to be mainly operated via the Schluter Smart Thermostat app. All features can be programmed and controlled using the app, and these features include remote access, time-temperature scheduling, maximum and minimum floor temperatures, maximum ambient temperature when in floor control mode, easy smart home integration, geofencing capabilities, etc. The basic installation setup can be programmed from the thermostat menu using the dot soft button and the arrows. Manual temperature adjustments can be made directly using the arrows. When connected to Wi-Fi, the thermostat provides convenient monitoring and adjustment of the floor warming system via our mobile app. Multiple heating cables may be connected to the thermostat up to the total heating load limit of 15 amps. The DITRA-HEAT-E-RRS power module may be used in conjunction with the thermostat when the heating load exceeds 15 amps (e.g., in large floor applications) to maintain a single point of control. This power module can only be used with the DITRA-HEAT-E-RS1 thermostat. Note: iPhones running iOS older than version 10 and Android running versions older than 6 are not officially supported by the Schluter Smart Thermostat App. Please refer to the Smart Thermostat Installation Manual and Schluter-DITRA-HEAT Installation Handbook for complete DITRA-HEAT system installation instructions. 1. DITRA-HEAT-E-RS1 must be installed in an electrical box. A single gang, deep electrical box or a double gang electrical box with a single gang mud ring is recommended to provide room for the wiring. The power supply must be shut off and all electrical connections must be made by a qualified person according to the electrical and building codes effective in your region. 2. Connect the heating cable ground braid to the grounding screw of the electrical junction box. Remove the faceplate from the thermostat power base by loosening the screw and tilting the thermostat upward. 3. For ease of installation, form the electrical line wires into an “M” or accordion shape. This will make it easier to fold them neatly into the electrical box. Loosen the load screws at the top of the thermostat until they stop. 4. Insert the heating cable conductors into the holes of the load terminals. Since there is no polarity, either heating cable conductor can be connected to either load terminal. Secure the conductors by tightening the screws. Insert the electrical line wires into the line terminals. Refer to the back of thermostat for proper wiring configuration. 5. Secure the wires by tightening the screws and fold the wires into the electrical box. Thread the floor temperature sensors through the slot opening at the bottom left of the thermostat power base. Tape up the secondary floor temperature sensor and secure to the power base. 6. Strip the ends of the floor temperature sensor to expose the wires for ease of installation. Insert the floor temperature sensor wires into the indicated terminals marked “Floor Sensor”. Note that the floor temperature sensor wires have no polarity and can be interchanged between the sensor terminals. Tighten the screws to secure the wires. 7. Align and secure the thermostat power base to the electrical box. The power, heating cable, and floor temperature sensor connections are now complete. Replace the thermostat faceplate and tighten the screw at the bottom of the unit. Note: Multiple DITRA-HEAT-E-HK heating cables can be connected and controlled by a single DITRA-HEAT-E-RS1 thermostat if the total current is less than 15 amps. The heating cable leads must be wired in parallel according to applicable electrical and building codes. Multiple DITRA-HEAT-E-HK heating cables over 15 amps cannot be connected to a single DITRA-HEAT-E-RS1 thermostat. Additional DITRA-HEAT-E-RS1 thermostats must be used or the DITRA-HEAT-E-RS1 thermostat may be combined with the DITRA-HEAT-E-RRS power modules.

  • Awesome Thermostat for Heated Floors
Installed my first heated bathroom floor with the Schluter Smart Thermostat and cabling. First of all, how wonderful it is to walk on a warm floor this past winter. What I like about this thermostat is it's ease of use using the Schluter smart app on my phone. You have the option, of course to set a schedule but it also has a GEO location of my phone option that I like. What this means is, it automatically turns on the heated floor when you're home and off when your not home based on where your phone is. It send me a notification when it's in Away mode vs Home mode. This was nice at first but now, I don't need to be notified each time I leave/return home so I've yet found how to turn that notification off. You set the desired temperature so once it's reached, the heat will turn off much the same way as your home HVAC system works. In the summer, when a heated floor is not required, it simply remains off automatically so no need to adjust anything by season. It can integrate with Alexa, which I have, but I don't use that functionality since the thermostat is pretty much set it and forget it operation. My only CON would be it's a bit pricey in my opinion. ... show more

  • Misleading add so be aware of what your getting
Here is my product experience since I received it. So I bought this thermostat cause it’s a smart thermostat PLUS it said it contained 2 floor sensors with it. See copied part next (Brand Name Schluter Model Name DHERT_105/BW_00 Included Components Dual Sensors, Floor Sensors, Energy Tracking) So I got it, opened it, and there was one sensor in there. So I called them, they did look into it and called me back and said that floor sensors come with the cable. I said well that’s not what the description says on the Amazon add. They said well that’s comes from schluter. I said well that’s false advertising and misleading information. So I called schluter. Schluter did confirm that the sensors come with the wire and not the thermostat. I told schluter that they need to change the wording then on this add because this third party is claiming that you wrote this. They later wrote saying they put 1 floor sensor in with that thermostat as complimentary. Which is all good and fine, but the problem I have is with the advertising of duel sensors with this product! Plain and clear! So be aware of this,, I was thoroughly pissed off about that. ... show more

  • Overpriced piece of !@#%
Well. This worked for exactly 2 days. I spent over $15K on a tile job including Schluter Ditra Heat and this was *supposed* to let me set a schedule for the floor heat. The problem is that once the network doesn't connect (which happened to me after just 2 days) you can't do !@#% with the thermostat. You can't turn the heat on, Nothing. What a piece of !@#%. I have a Suntouch floor in another bath that has worked FLAWLESSLY for over 10 years and I have a cheeeeap as dirt Vevor (yeah, I know) setup at another house that's worked perfectly for over 3 years. I should have kept with that brand. ... show more

  • Works as intended.
Screen size is small. Functions great on the app. The face is disappointing. It’s not touch screen. Does it work? Yes! Is the app good? Yes. It’s easy to use and functional.
