Resideo TL8100A1008 Thermostat
The Resideo TL8100A1008 from the LineVoltPro 8000 series is a versatile 7-day programmable hydronic thermostat engineered for high-performance control in residential and commercial heating. This specialized line voltage thermostat handles a wide operational range, including 120Vac, 240Vac, and 24Vdc, making it a reliable solution for technicians working on millivolt compatible systems such as gas fireplaces or wood boilers. Its single-stage heat logic is specifically optimized for hot water heating, featuring integrated pump protection to prevent seizing during long periods of inactivity. With a temperature setting range of 40-85 degrees Fahrenheit and screw terminal connections, this vertical mount thermostat ensures precise terminal designations for R, W, and optional remote inputs. The non-condensing humidity tolerance of 0-95% makes it ideal for mechanical rooms where environmental control is paramount for equipment longevity.
Key Benefits for the Contractor- Universal Compatibility: Works with 24V, 120V, and 240V systems, including millivolt and hot water applications.
- Advanced Pump Protection: Extends the life of circulator pumps by activating them briefly during the off-season.
- Robust 7-Day Programming: Allows for independent schedules to maximize energy efficiency without sacrificing building comfort.
- Flexible Power: Designed to operate on 2 AA batteries while maintaining configuration memory during replacement.
- Precision Control: Utilizes a thermistor sensor for a narrow temperature differential, reducing system cycling.
Can the TL8100A1008 control a circulator pump directly?
Yes, it is rated for a 5A resistive and 2A inductive load, making it suitable for direct control of small pumps or zone valves across multiple voltages.
Is this unit suitable for electric baseboard heaters?
While compatible with 240V, it is specifically optimized for hydronic and millivolt systems; verify that the total wattage does not exceed 1200W at 240V.
How does the pump protection feature work?
The thermostat automatically initiates a 1-minute pump cycle every 24 hours of inactivity to prevent scale buildup and pump seizure in hydronic loops.
