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.
2. 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.
3. Connect the heating cable ground braid to the grounding screw of the electrical junction box.
4. Remove the faceplate from the thermostat power base by loosening the screw and tilting the thermostat upward.
5. 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.
6. 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.
7. Secure the conductors by tightening the screws.
8. Insert the electrical line wires into the line terminals. Refer to the back of thermostat for proper wiring configuration.
9. Secure the wires by tightening the screws and fold the wires into the electrical box.
10. 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.
11. 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.
12. Align and secure the thermostat power base to the electrical box.
13. 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.
