Schluter DITRA-HEAT-E-R Non-Programmable Thermostat — Simple Floor Heating Control
The Schluter DITRA-HEAT-E-R is a non-programmable digital thermostat specifically engineered to control DITRA-HEAT-E-HK heating cables (120 V or 240 V). With a built-in Class A ground fault circuit interrupter (GFCI), clear backlit digital display and included floor sensor, it provides safe, reliable and straightforward on/off temperature control for electric floor warming systems.
Designed for installers and homeowners who prefer simple, dependable operation, the DITRA-HEAT-E-R supports up to two heating cables (total load ≤ 15 A) and may be paired with the DITRA-HEAT-E-RR power module for larger installations requiring higher capacity — while maintaining a single point of control.
Key Features and Benefits
- Simple on/off control — fast and intuitive operation via digital interface
- Built-in Class A GFCI (5 mA) — enhanced safety for wet areas and bathrooms
- Includes floor temperature sensor — accurate floor sensing for precise comfort
- Dual-voltage support — compatible with 120 V and 240 V heating cables
- Supports two heating cables — up to the 15 A total load limit
- Expandable with power module — use DITRA-HEAT-E-RR for loads above 15 A
- Clear backlit display — easy reading in any light
- Sleek white finish — blends with modern interiors and trim
- Compact, installer-friendly design — wall-mounted, fits standard electrical boxes
Please refer to the Quick Guide and Schluter DITRA-HEAT Installation Handbook for complete DITRA-HEAT system installation instructions.
- DITRA-HEAT-E-R 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 electrician, according to the electrical and building codes effective in your region.
- Connect the heating cable ground braid to the ground wire from the electrical panel.
- Remove the faceplate from the thermostat power base by loosening the screw and tilting the thermostat upward. Remove the back cover clip as well.
- 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.
- Insert the heating cable conductors into the load terminals from the bottom. 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 from the top. Refer to the back of thermostat for proper wiring configuration.
- Secure the wires by tightening the screws and fold the wires into the electrical box.
- Align and secure the thermostat power base to the electrical box.
- Thread the floor temperature sensors through the opening at the bottom right of the thermostat power base. Tape up the secondary floor temperature sensor and secure to the power base.
- Strip the ends of the floor temperature sensor to expose the wires for ease of installation. Insert the floor temperature sensor wires into terminals C and D. Note that the floor temperature sensor wires have no polarity and can be interchanged between C and D terminals. Tighten the screws to secure the wires.
- 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: Two DITRA-HEAT-E-HK heating cables can be connected and controlled by a single DITRA-HEAT-E-R 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-R thermostat. Additional DITRA-HEAT-E-R thermostats must be used or the DITRA-HEAT-E-R thermostat may be combined with the DITRA-HEAT-E-RR power modules.
