Tekmar Controls 561 Thermostat

The Tekmar 561 WiFi Thermostat is a high-performance, one-stage heat thermostat designed specifically for the rigorous demands of hydronic heating systems, including baseboards, radiators, and radiant floor heating. Operating on 24Vac or 24Vdc, this unit integrates seamlessly with the Watts Home mobile app, allowing for professional-grade remote temperature control and system monitoring. The 3.5-inch color touchscreen interface provides a clear digital display for local adjustments, while the 7-day programmable schedule offers four daily events to optimize energy loads. Technicians will appreciate the early start feature, which utilizes a learning algorithm to ensure specific setpoints are met precisely at the scheduled time. For advanced comfort and hardwood floor protection, the 561 supports optional floor sensors (like the Tekmar 079) to manage floor minimum and maximum temperature limits. This smart heating control also features energy monitoring and email error notifications, ensuring contractors can maintain and troubleshoot systems effectively.
