Honeywell T8034N1007 Thermostat

The Honeywell T8034N1007 is a mercury-free non-programmable mechanical thermostat designed for 1H/1C conventional systems and single-stage heat pumps without auxiliary heat. This Honeywell Econostat features a bimetal sensor element and a precise snap-action switch, ensuring reliable performance in demanding environments. As a professional-grade low voltage thermostat, it operates on a 20-30Vac range with a manual changeover system (Heat-Off-Cool) and dedicated Auto-On fan switching. The horizontal-mount design is built for easy installation on a standard junction box or directly to the wall. This unit serves as the direct replacement for 1F56-306 and older mercury-filled models, meeting all current compliance standards. With a temperature setpoint range of 45-95°F and +/- 2-degree accuracy, the T8034N1007/U provides the consistent mechanical operation that contractors and technicians rely on for simple, high-durability residential or light commercial applications.

• Environmental Compliance: Fully mercury-free thermostat design, meeting modern regulatory and disposal standards.
• Broad Compatibility: Supports 1 Heat / 1 Cool conventional systems and single-stage heat pumps lacking auxiliary heat strips.
• Technical Precision: Integrated bimetal sensing element and snap-action switching eliminate the drift associated with older mechanical designs.
• Simplified Wiring: Standard terminal designations (R, RC, W, Y, G, O, B) allow for rapid field installation and retrofitting.
• Reliable Interface: Features a clear analog temperature scale and integrated thermometer for immediate visual verification.

Common Questions

Is the Honeywell T8034N1007 compatible with multi-stage systems?
No, this model is specifically engineered for single-stage heating and cooling. It is not designed for systems requiring auxiliary heat or multi-stage compressor control.

Does this thermostat require a C-wire for operation?
As a mechanical, non-programmable thermostat, the T8034N1007 operates via 24V low voltage switching and does not typically require a common wire for basic functionality, though professional verification of existing wiring is recommended.

Can I use this to replace an old mercury-vial thermostat?
Yes, the Honeywell T8034N1007 is the industry-standard replacement for mercury-based Econostat models and the White-Rodgers 1F56-306, providing the same horizontal form factor.
