Resideo TH5110D1022 Thermostat
The Resideo TH5110D1022 is a professional-grade, non-programmable digital thermostat from the reliable FocusPro 5000 series, engineered for high-accuracy climate control in single-stage HVAC systems. This horizontal-mount unit is the direct industry replacement for the legacy TH5110D1006, providing a seamless retrofit for technicians. It supports 1 heat/1 cool conventional systems and 1H/1C heat pumps without auxiliary heat. Built with a 2.98 sq. in. large backlit display, it ensures high visibility for setpoints and room temperatures in dark mechanical rooms or hallways. Contractors appreciate the dual-power options, allowing for hardwiring (24VAC) or 2x AA battery operation. With a precise +/- 1 degree accuracy and a 750mV millivolt system compatibility, this thermostat handles everything from standard gas furnaces to older standing pilot systems. The auto or manual changeover feature eliminates nuisance calls by allowing the system to toggle between heating and cooling based on load. Its flip-out battery door facilitates rapid maintenance without requiring the technician to pull the faceplate off the wall, preserving terminal connections.
Key Benefits
- Broad Compatibility: Supports 24VAC conventional gas/oil/electric systems, 1-stage heat pumps, and 750mV millivolt heating applications.
- Precise Comfort Control: Maintains temperature within +/- 1°F of the setpoint for consistent residential or light commercial comfort.
- Simplified Maintenance: Features an easy-access battery compartment and a straightforward push-button interface for end-users.
- System Versatility: Equipped with Heat-Off-Cool-Auto system switching and Auto-On fan controls to manage diverse equipment configurations.
- Compact Footprint: Designed for horizontal mounting at 3-7/16" H x 4-1/2" W, making it an ideal choice for covering existing wall marks.
Common Questions
Is the TH5110D1022 compatible with heat pumps that have emergency heat?
No, this specific FocusPro 5000 model is designed for 1H/1C systems only. If your heat pump utilizes auxiliary or emergency heat strips, you should use the TH5220D1029 or another multi-stage thermostat.
Can this thermostat be used on a 2-wire heat-only system?
Yes, the TH5110D1022 works with 2-wire R and W configurations, including millivolt systems, and can run entirely on battery power if a common wire is not present.
What is the difference between the TH5110D1022 and the TH5110D1006?
The 1022 is the current production model and a direct functional replacement for the discontinued 1006, maintaining the same terminal designations and mounting holes for an easy swap.
