Tekmar Controls 519 Thermostat

The Tekmar Controls 519 Thermostat is a purpose-built solution for precise radiant floor heating management in hydronic systems. This 24Vac/24Vdc one stage radiant heat thermostat utilizes advanced Pulse Width Modulation (PWM) technology to eliminate the temperature swings common in standard on/off controls, ensuring consistent thermal mass stability. Engineered for versatility, it functions as a direct replacement for the legacy Tekmar 509 and features a 10k NTC thermistor Slab Sensor 079 to monitor floor temperatures directly. This prevents overheating of sensitive floor finishes while providing accurate air and floor temperature control. The unit includes an auto heating cycle to optimize energy delivery and integrated freeze protection for system safety during extreme cold. Its vertical orientation and clear, backlit display make it an industry standard for professionals requiring reliable, non-programmable zoning control in residential and commercial hydronic applications.

Key Benefits
  • PWM Technology: Prevents short-cycling and temperature overshoot in high-mass radiant systems.
  • Dual Sensing: Includes the 079 slab sensor for precise floor temperature limiting and enhanced comfort.
  • System Compatibility: Seamlessly integrates with hydronic heating zones, zone valves, and switching relays.
  • Ease of Installation: Designed with a wall-mounted base for simplified wiring and 10-30V AC/DC flexibility.
  • Freeze Protection: Automatically triggers the heat if temperatures drop, protecting critical piping infrastructure.
Common Questions

Is the Tekmar 519 compatible with older 509 installations?
Yes, the 519 is specifically designed as a direct replacement for the Tekmar 509, fitting existing footprints and wiring configurations.

Can I use this thermostat for electric radiant floor heating?
While designed for hydronic heating zones, it can control electric systems if a properly rated switching relay is used to handle the secondary load.

Do I have to use the included slab sensor?
The 519 can operate based on air temperature only, floor temperature only, or a combination of both; however, using the slab sensor is highly recommended for radiant floor protection.
