The 1F93-380 digital thermostat is system-selectable between single-stage, multistage, and heat pump. It has seven-day in-dependent programming and auto changeover. Its microprocessor allows adjustment of blower delay settings and is designed to maintain temperature accuracy to within 0.5 degrees F of setpoint. According to the manufacturer, the thermostat’s Energy Management Recovery feature allows it to automatically select the proper time to start heating or cooling for the most efficient operation, potentially reducing heating and cooling costs by up to 33 percent. Built-in diagnostics monitor the thermostat’s operation and aid with troubleshooting.
