Resideo T87N1000 Thermostat
The Resideo T87N1000 represents the modern evolution of the iconic Honeywell Round thermostat, specifically engineered for reliable 24VAC control in residential and light commercial applications. This non-programmable thermostat features a manual changeover design and is compatible with 1-stage heat/1-stage cool conventional systems as well as heat pumps without auxiliary heat. Built with a mercury-free thermistor sensor, the unit delivers precise ±1°F accuracy across a 40°F to 90°F setpoint range. The battery-assisted power stealing method ensures consistent performance even on systems with low power availability, while the Premier White finish and classic twist-dial interface provide a familiar experience for end-users. For contractors, the standard R, Rc, W, Y, G, O, B terminal designations and included decorative cover plate simplify professional HVAC thermostat installation by hiding existing wall marks. Note that the T87N1000 and T87N1000/U are functionally identical low voltage thermostats.
Key Benefits
- Universal Compatibility: Works with standard gas, oil, or electric 1H/1C systems and air-to-air heat pumps.
- Mercury-Free Construction: Environmentally compliant electronic design replaces older mechanical mercury-switch models.
- Enhanced Visibility: Features an enlarged scale and raised numbers for easier temperature adjustments.
- Power Flexibility: Utilizes power-stealing technology with battery assistance to maintain 18-30Vac operation.
- Precision Control: Professional-grade thermistor sensor maintains tight 1-degree temperature differentials.
Common Questions
Is the Resideo T87N1000 compatible with multi-stage heat pumps?
No, this model is designed strictly for single-stage heating and cooling. For heat pumps with auxiliary or emergency heat, a 2H/1C or multi-stage controller is required.
Does this unit require a common (C) wire?
The T87N1000 is a power-stealing thermostat that can typically operate without a C-wire on most 24V systems, though it uses battery assistance to ensure stable relay switching.
Can I use this for 120V or 240V baseboard heating?
No, this is a low voltage thermostat rated for 18-30Vac. Do not connect it to line voltage systems, as this will damage the electronic components.
