We’ve improved the best-selling digital thermostat by combining a single stage, multi-stage and heat pump into one universal thermostat. And better yet we’ve enhanced it with the new styling and home comfort features, specially designed for all systems. It now offers more control, more convenience and more value than the competition. And it’s backed with the reputation of White-Rodgers — pioneers in home comfort since 1937. More Accuracy and Control. If you’re in the process of upgrading a multi-stage, heat pump or single stage system, don’t forget the “brain” for your new system…your thermostat. Our White-Rodgers 80 Series can maintain a set temperature to within one degree. Plus, there’s a permanent memory that saves all programs and settings during a power loss. Comfort and Convenience with Versatility. The programmable models deliver perfect comfort, as they automatically change to the temperature you selected for wake-up, during the day, evening hours and while you sleep. You can also configure them with minimum and maximum temperature range for cooling or heating. The new 40% larger lighted display makes for clearer low-light viewing. Maximum Energy Savings. Program heating and cooling times to cut energy use, not comfort. You can save up to 33% in energy costs, depending on your home’s location, climate and program selections. Now you can have it all…energy savings, with comfort and convenience!
