7. FUNCTIONS7-1. Operation FunctionsEmergency operation SENSOR DRYDuring DRY operation, the system adjusts the roomtemperature and fan speed according to the conditions in theroom, in order to maintain a comfortable room environment.SENSOR DRY operationDRY operation is as shown in the figure below.PAM- controlIn order to further improve inverter performance, control isswitched between PWM control at low operation speeds, andPAM control at high operation speeds, making the mosteffective use of power.The compressor operation frequency varies.The indoor fan operates with 1/f fluctuation.The compressor operates at a low operating frequency.The indoor fan operates with 1/f fluctuation.Monitoring operation takes place when the room temperatureis below 59°F( 15°C), or more than 5°F(3°C) below the settemperature.When the monitoring range is entered, the compressor stops,and the indoor fan operates with 1/f fluctuation.DRY ADRY BMonitorConditions are monitored at alltimes when the room temperatureis below 59°F(15°C).LoadCOOL zoneA zoneB zoneEmergency operation is available when the remotecontroller malfunctions, has been lost, or otherwisecannot be used.The set temperature is 4°F(2°C) below the detected roomtemperature in the case of cooling operation.(GREEN) (Lamp Off)COOL STOPTo operate the system, press the OPERATION button,which is also used as the receiver, below the unit display.Each time this button is pressed, the OPERATION lampchanges color to indicate the type of operation. Select thedesired type of operation.The Sensor Dry operation during the Low Ambient CoolingMode (outside air temperature:59°F(15°C) or lower) is asfollows.The compressor operates a cycle of 3 minutes ON and 6minutes OFF repeatedly.NOTEDRY A DRY Band(CLxx models only)32
