Copeland Comfort Control (White Rodgers) 1F86EZ-0251 Thermostat

The Copeland Comfort Control (White Rodgers) 1F86EZ-0251 is a professional-grade 1H/1C non-programmable thermostat engineered for simplified climate management without sacrificing precision. Built for single-stage heating and cooling systems, including heat pumps (without auxiliary heat) and 24V or millivolt applications, this unit features the Blue Easy Set™ logic. It eliminates complex scheduling while offering three temperature pre-sets—Home, Sleep, and Away—allowing for rapid setpoint adjustments with a single touch. Technical features include a 2-square-inch backlit digital display for high visibility in low-light mechanical rooms and permanent memory retention to preserve settings during a total power loss. The dual-powered design supports either a hardwired "C" wire or battery operation via two AA batteries. For contractors, the color-coded push-connect terminals streamline the wiring process, while the "Cool Savings" feature provides peak load energy management. This low voltage digital thermostat is an ideal choice for residential and light commercial retrofits where intuitive operation and vertical/horizontal mounting flexibility are required.
