Programmable Thermostat

This replacement digital programmable thermostat is engineered as a direct substitute for the Resideo TH6220D1028/U and compatible Honeywell Home FocusPRO 6000 series units. Designed for HVAC professionals and facility managers, this thermostat delivers precise climate control for residential and light commercial applications. The unit supports advanced heating and cooling capabilities, including up to two heat pump stages or two conventional heat stages, paired with one heat pump stage or two conventional cooling stages. This versatile configuration accommodates a wide range of heating and air conditioning systems. The control range spans 40 to 90 degrees Fahrenheit (4 to 32 degrees Celsius), providing comprehensive temperature management across seasonal demands. The thermostat features a large, backlit digital display that clearly shows both current room temperature and user-set temperature for quick reference and diagnostics. Programming flexibility is a core strength, with selectable scheduling options supporting either a 5-1-1 format (separate programming for weekdays, Saturday, and Sunday) or a 5-2 format (weekdays and weekend settings). This adaptability allows optimization for various occupancy patterns. Measuring 5 13/16 inches wide by 1 1/2 inches deep by 3 9/16 inches high, the horizontal-mount design fits standard wall installations without requiring modifications. The unit operates on 20 to 30 VAC power and accommodates both hardwired and battery-backup configurations for reliable operation during power interruptions. Terminal connectivity includes R, RC, C, W-O/B, G, Y, W2-AUX/E, and Y2-L connections, ensuring compatibility with standard HVAC wiring schematics. This replacement thermostat is ideal for retrofit applications, equipment upgrades, and new installations where reliable temperature control and programmable scheduling are essential.
