Features
Liquid Crystal Display (LCD) is backlit and easy to read. Most frequently used keys are located near LCD for quick and easy access to information. Models available with outdoor temperature sensor capability. The sensor is more accurate than a thermometer. Configurable features allow one model to be used to replace many different models. Degree F or C temperature display. Automatic or manual changeover. Electric or conventional heat fan operation. Adjustable heating cycle rate. Adjustable range stops. Minimum off time for cooling compressors and heat pumps protects and extends the equipment life. Easy installation, setup and self-test saves installer setup time. Installer selectable LED on T8511 Heat Pump models. System test simplifies troubleshooting and saves time by overriding the time delays. Setpoints are permanently held in memory (no batteries used) and retained during power outages.
