White-Rodgers 1F80-0261 Thermostat

For service professionals managing light commercial or residential maintenance, the White-Rodgers 1F80-0261 provides a reliable 1H/1C programmable thermostat solution. This Emerson Blue 2" display thermostat is engineered for versatility, offering compatibility with 24V and millivolt systems, including gas, oil, or electric configurations. The 5+1+1 day scheduling flexibility allows for distinct Saturday and Sunday programming, which is ideal for optimizing efficiency in various occupancy patterns. As a digital 1H/1C thermostat, it utilizes solid-state microcomputer technology to maintain precise temperature control within ±1°F.

The unit features a clear, backlit 2-inch screen for high visibility in low-light environments. For installation flexibility, it supports dual power options, functioning via 24VAC hardwiring or 2 AA batteries. The horizontal profile fits standard junction boxes, and the terminal layout (R, C, W, Y, G, O/B) ensures a straightforward White-Rodgers 1F80-0261 wiring process. Technicians will appreciate the 1F80-0261 replacement compatibility, as it directly updates older 1F70-358 and 1F80-261 models. Built-in performance features include adjustable heating anticipation, a permanent program memory, and compressor lockout protection to safeguard equipment during rapid cycling.

• Universal Compatibility: Works with single-stage heating and cooling systems, including heat pumps (without auxiliary heat) and millivolt applications.
• Energy Management: Includes "Cool Savings" and selectable recovery modes to reduce peak demand load and improve system efficiency.
• Maintenance Alerts: Features a selectable air filter change indicator to help HVAC contractors ensure end-user equipment longevity.
• Installation Versatility: Dual-power design allows for hardwired "C" terminal connection or stand-alone battery operation.
• Retrofit Ready: Comes with an F61-2634 wall plate and junction box adapter to cover footprint gaps from older controls.

• How do you program the White-Rodgers 1F80-0261 for weekends? Use the PRGM button to navigate to the 5-day (weekday), 1-day (Saturday), and 1-day (Sunday) blocks to set four distinct time and temperature periods for each.
• Can this thermostat control a heat pump? Yes, provided it is a single-stage system without auxiliary heat. The internal GAS/ELEC switch must be set to ELEC for heat pump operation.
• Why is the "Cool On" light blinking? This indicates a 5-minute safety delay. To protect the compressor from short-cycling, the thermostat will wait before re-energizing the cooling circuit.
• What batteries are required? The unit uses two standard AA alkaline batteries, which provide backup for program retention and the clock during power loss.
