(k)(l)'11 • SCM-SM-1102) Automatic louver level setting during heatingAt the hot start with the heating thermostat OFF, regardless whether the auto swing switch is operated or not (auto swingor louver stop), the louver takes the level position (In order to prevent the cold start). The louver position display LCDcontinues to show the display which has been shown before entering this control.3) Louver-free stop controlWhen the louver-free stop has been selected with the indoor function of wired remote controller “ POSITION”, thelouver motor stops when it receives the stop signal from the remote controller. If the auto swing signal is received fromthe remote controller, the auto swing will start from the position where it was before the stop.Note (1) When the indoor function of wired remote controller “ POSITION” has been switched, switch also the remote control function “POSITION” in the same way.Compressor inching prevention control1) 3-minute timerWhen the compressor has been stopped by the thermostat, remote controller operation switch or anomalous condition,its restart will be inhibited for 3 minutes. However, the 3-minute timer is invalidated at the power on the electric powersource for the unit.2) 3-minute forced operation timer• Compressor will not stop for 3 minutes after the compressor ON. However, it stops immediately when the unit isstopped by means of the ON/OFF switch or by when the thermister turned OFF the change of operation mode.• If the thermostat is turned OFF during the forced operation control of heating compressor, the louver position (with theauto swing) is returned to the level position.Note (1) The compressor stops when it has entered the protective control.Drain pump control [Applicable models:FDTC and FDUM]1) This control is operated when the inverter frequency is other than 0 Hz during the cooling operation and automaticcooling and dehumidifying operations.2) Drain pump ON condition continues for 5 minutes even when it enters the OFF range according to 1) above after turningthe drain pump ON, and then stops. The 5-minute delay continues also in the event of anomalous stop.3) The drain pump is operated with the 5-minute delay operation when the compressor is changed from ON to OFF.4) Even in conditions other than the above (such as heating, fan, stop, cooling thermostat OFF), the drain pump control isperformed by the drain detection.5) Following settings can be made using the indoor function setting of the wired remote controller.( i ) : Drain pump is run during cooling and dry.(ii): Drain pump is run during cooling, dry and heating.(iii): Drain pump is run during cooling, dry, heating and fan.(iv): Drain pump is run during cooling, dry and fan.- 27 -
