White-Rodgers 1F95EZ-0671 Thermostat

The White-Rodgers 1F95EZ-0671 is a high-performance Blue Series 6" Easy Reader universal thermostat engineered for extensive system compatibility. This 7-day programmable thermostat supports up to 4 heat/2 cool stages on heat pump systems and 2 heat/2 cool stages for conventional systems. Designed for versatility, it operates via 24VAC hardwire or mV-30Vac battery power, making it compatible with millivolt systems and 3-wire zone valves. The large 6-square-inch display with high-contrast blue backlighting ensures visibility in various lighting conditions. For complex installations, it features dual fuel logic to manage heat pump and fossil fuel furnace transitions without requiring an outdoor sensor. It includes auto changeover, programmable fan, and keypad lockout for enhanced control. The 1F95EZ-0671 thermostat maintains a precise +/- 1-degree setpoint accuracy across a 45-99°F range, catering to both residential and light commercial demands where staging control is paramount.

• Universal Compatibility: Configures easily for single-stage, multi-stage, or heat pump systems, reducing the need to stock multiple models.
• Dual Fuel Efficiency: Built-in logic manages dual fuel systems effectively without the added cost and labor of an external fossil fuel kit.
• Enhanced Visibility: The Blue Easy Reader display features large characters and a 6-inch screen, specifically designed for improved legibility.
• Flexible Powering: Supports hardwired (C-wire), battery-powered, or power-stealing configurations to suit various field wiring scenarios.
