White-Rodgers 1F82-0261 Thermostat

The White-Rodgers 1F82-0261 is a performance-grade two-stage heat pump thermostat designed for legacy 2H/1C applications. Built on the Emerson Blue series platform, this 24V programmable pulse thermostat utilizes a 5+1+1 day schedule, allowing contractors to customize terminal outputs for weekdays and weekends independently. With a 2-square-inch backlit display and high-contrast characters, reading system status in dim mechanical rooms or residential hallways is straightforward. The unit supports dual power configuration, operating via system power (24VAC) or battery backup using two AA alkaline batteries, ensuring permanent program retention during power cycles. Professional technicians will appreciate the color-coded push-connect terminals—R, C, G, Y, W2, O/B, and L—which simplify the interface for multi-stage heating with electric or fossil fuel auxiliary backups. Integrated Energy Management Recovery (EMR) logic ensures the system reaches the desired setpoint exactly at the scheduled time, optimizing compressor run-times and auxiliary heat engagement.

• Multi-Stage Control: Optimized for 2 Heat / 1 Cool heat pump systems with emergency and auxiliary heat terminal support.
• Technical Precision: Features an adjustable temperature differential (0.6° to 1.7°F) for precise cycling control and Energy Management Recovery.
• Installation Versatility: Dual-powered design functions as a hardwired 24VAC thermostat or as a battery-operated unit for retrofit applications.
• Field-Serviceable Display: The 2-inch backlit Emerson Blue display provides clear visibility for setpoints, current room temperature, and system alerts.
• Robust Compatibility: Horizontal profile fits standard junction boxes using the included F61-2634 wallplate adapter for a clean finish.

• Does this model support millivolt systems? No, this is a 24VAC low-voltage control specified for standard heat pump systems.
• How do you handle the reversing valve (O/B) configuration? The O/B switch is factory set to 'O' (energize in cool), but it can be manually switched to 'B' (energize in heat) depending on the condensing unit manufacturer requirements.
• Will it save settings during a power outage? Yes, the 1F82-0261 utilizes non-volatile memory for permanent program retention even without batteries.
