ENERGY SAVER

During normal operation, the thermostat automatically controls cooling and the fan runs
continuously. When the ENERGY SAVER is selected, the thermostat automatically controls
cooling and the fan automatically stops when the compressor is not operating. (Fan will stop 30
seconds after the compressor stops. After the fan stops, the fan is programmed to rotate for
approx. 2 minutes to detect room temperature. This will occur within a 20 min time span.)
