Programmable Thermostat

This 7-day programmable hydronic thermostat is engineered for precise temperature control in hydronic heating systems, making it an ideal replacement for the Resideo TL8100A1008/U and compatible applications. Designed for both residential and light commercial installations, this thermostat manages 2-way and 3-way zone valves and circulator pumps across multiple voltage configurations, supporting 24 Vdc, 30 Vdc, 120 Vac, and 240 Vac applications. The unit operates reliably within a temperature range of 32 Degrees F to 122 Degrees F with user-selectable setpoints between 40 Degrees F and 85 Degrees F, accommodating diverse climate control requirements. Measuring 4.9 inches in height, 3.8 inches in width, and 1 inch in depth, the compact design fits seamlessly into standard wall-mounted installations. Power flexibility is provided through dual options: battery operation using two AA batteries for emergency backup or simple installations, and hardwired connections for permanent system integration. The thermostat handles electric heating loads up to 1200W at 240V and is compatible with both resistive and inductive loads, ensuring broad compatibility with existing HVAC infrastructure. Operating in environments with humidity levels from 0% to 95% non-condensing, this unit performs consistently across typical building conditions. The 7-day programmable scheduling allows facility managers to optimize energy consumption by customizing heating cycles for different days and times, reducing operational costs while maintaining occupant comfort. This replacement component provides reliable, energy-efficient control for hydronic heating systems in residential, commercial, and industrial facilities.
