Resideo TH6210U2001 Thermostat
The Resideo TH6210U2001 is a professional-grade, programmable T6 Pro thermostat engineered for high-reliability control of 1 Heat/1 Cool conventional systems and 2 Heat/1 Cool heat pump systems. As the direct replacement for 2220NC, this model utilizes the standardized UWP mounting system, allowing for rapid field swaps and a consistent installation footprint across the entire T-Series line. Whether configured for 7-day, 5-2, or 5-1-1 day scheduling, or set to non-programmable mode for straightforward operation, the TH6210U2001 provides ±1°F temperature accuracy and a 1°F differential for precise climate management.
Built for the rigors of service work, this unit supports both battery or hardwired 24 VAC power through the R and C terminals. The integrated LED backlit display ensures visibility in mechanical rooms, while the numeric installer setup (ISU) menu streamlines configuration of cycles, compressor protection, and adaptive intelligent recovery without requiring a separate manual. With a wide operating humidity range of 5-90% non-condensing and a robust temperature setpoint range (40-90°F Heat / 50-99°F Cool), this thermostat is a versatile solution for gas, oil, electric, and geothermal applications.
Key Benefits- Universal Compatibility: Supports standard efficient gas forced air, heat pumps, and 750mV hydronic systems.
- Contractor-Friendly Installation: Uses the UWP mounting system and includes a J-box adapter and decorative cover plate for a clean finish.
- System Protection: Built-in 5-minute compressor protection prevents short-cycling to extend equipment life.
- Smart Recovery: Features Adaptive Intelligent Recovery to ensure the setpoint is reached exactly at the programmed time.
- Flexible Maintenance: Programmable reminders for air filter and battery replacement reduce nuisance service calls.
- Is the TH6210U2001 dual-fuel compatible? No, this specific model does not support dual-fuel (fossil fuel backup) or outdoor sensors; those require the TH6320U or TH6220U models.
- Can this replace an older Honeywell PRO series? Yes, it is a recommended upgrade for the PRO 2220NC, TH4210D1005, and TH2210DV1006.
- Does this thermostat require a C-wire? No, the T6 Pro can run strictly on two AA batteries, though hardwiring is recommended for continuous backlight operation.
