Expand Heated Floor Capacity Without Adding Extra Controls

The Schluter DITRA-HEAT-E-RR Power Module Thermostat is designed to increase the heating capacity of Schluter electric radiant floor heating systems while maintaining a single, centralized point of control. When paired with compatible DITRA-HEAT-E-WiFi, DITRA-HEAT-E-RT, or DITRA-HEAT-E-R thermostats, the module extends system output for larger heated floor installations that exceed a standard thermostat's 15-amp capacity.

Ideal for expansive residential and commercial floor warming projects, the DITRA-HEAT-E-RR provides a seamless way to scale your heating system without sacrificing ease of operation.

Increase Heating Capacity for Large Floor Installations

For projects requiring more heating power, the DITRA-HEAT-E-RR adds an additional 15 amps of capacity while remaining fully synchronized with a compatible Schluter thermostat. This allows installers to expand electric floor heating systems efficiently without introducing multiple independent controls.

Up to 16 power modules can be connected in series using low-voltage signal wiring, making the system suitable for even the largest radiant floor heating applications.

Expansion features include:

• Adds 15 amps of additional heating capacity
• Supports large heated floor installations
• Connect up to 16 power modules in series
• Maintains a single thermostat for centralized control
• Low-voltage communication between thermostat and modules

Seamless Integration with Schluter Heating Controls

The DITRA-HEAT-E-RR is engineered specifically for Schluter DITRA-HEAT systems, ensuring reliable compatibility with supported thermostats and heating cables. The module is controlled directly by the thermostat through a low-voltage two-conductor 20 AWG signal wire, allowing the entire heating system to operate as one integrated solution.

Compatible thermostats include:

• DITRA-HEAT-E-WiFi Thermostat
• DITRA-HEAT-E-RT Touch Program Thermostat
• DITRA-HEAT-E-R Non-Programmable Thermostat

This integrated design simplifies installation while providing consistent system performance.

Built-In Electrical Protection for Reliable Operation

Safety remains a priority even as heating systems grow in size. The DITRA-HEAT-E-RR features a built-in Class A Ground Fault Circuit Interrupter (GFCI) to help protect electric floor heating installations during normal operation.

The module supports both 120V and 240V heating cables, making it suitable for a wide variety of residential and commercial radiant floor heating projects.

Technical highlights:

• Built-in Class A GFCI protection
• Compatible with 120V and 240V systems
• Low-voltage thermostat communication
• Designed for Schluter DITRA-HEAT installations
• Reliable performance for expanded heating zones

Ideal for High-Capacity Radiant Floor Heating Projects

The DITRA-HEAT-E-RR is an excellent solution whenever electric floor heating systems require more power than a standard thermostat can supply. It allows contractors to expand system capacity while preserving straightforward operation for homeowners.

Common applications include:

• Large bathrooms
• Open-concept living spaces
• Kitchens
• Commercial interiors
• Luxury residential projects
• Multi-room heated floor systems
• High-capacity renovation projects

Professional Expansion for Scalable Heated Floor Systems

Whether you're designing a luxury residential installation or a large commercial radiant floor heating system, the Schluter DITRA-HEAT-E-RR Power Module provides the flexibility to expand heating capacity without increasing operational complexity.

Its seamless integration with compatible Schluter thermostats, built-in electrical protection, and scalable design make it an essential component for larger DITRA-HEAT floor warming systems.
