White-Rodgers 1F86-0244 Thermostat

The White-Rodgers 1F86-0244 is a dependable non-programmable 24V thermostat designed for 1H/1C conventional systems and single-stage heat pumps without auxiliary heat. Engineered for low voltage NEC Class II systems, this unit offers a reliable interface for service calls where simplicity is preferred over complex scheduling. With a setpoint range of 45°F to 90°F and a 2-square-inch blue backlit display, it ensures high visibility in low-light mechanical rooms or residential hallways. Contractors will appreciate the easy-to-wire push-connect color-coded terminals (R, C, Y, W, G, O/B) and millivolt compatibility, making it a versatile addition to any truck stock. The dual-power design allows for hardwired or battery-operated installation, with permanent program retention ensuring setpoints are maintained during a total power loss. Advanced features include adjustable heating cycle anticipation (Fast/Slow), compressor lockout protection, and a manual changeover switch for consistent climate control.

Common Questions

Is the White-Rodgers 1F86-0244 compatible with multi-stage equipment?
No, this model is strictly for single-stage 1H/1C systems. If you are servicing a multi-stage heat pump with auxiliary heat, you will need a 1F83 or 1F85 series controller.

Can I use this thermostat with 120V or 240V electric baseboard heat?
No. This is a low voltage thermostat rated for 30VAC maximum. Using this on line voltage circuits will cause immediate control failure and creates a fire hazard.

How do I adjust the heating cycle rate for various furnace types?
The internal configuration menu allows for Fast (FA) or Slow (SL) anticipation settings. Use the Fast setting for high-efficiency gas furnaces and the Slow setting for oil or larger mass systems to prevent short cycling.
