7.FUNCTION 7-1 Cool Mode Operation (RT - SPT) [ over 3 min over 5 min COMP OFAN over 30 sec IFAN In Cool Mode, the operation of the Compressor (COMP), Outdoor Fan (OFAN) and Indoor Fan (IFAN) are determined by the difference between the Room Temperature (RT) and the Set Point Temperature (SPT) as in the graph above. -
Page 20: Heat Mode Operation
7-2 Heat Mode Operation (RT - SPT) [ COMP 30 sec IFAN Note 1 Note 2 The Heat Mode operation is similar to the Cool Mode operation. The COMP, OFAN and IFAN are mainly controlled by the value of (RT – SPT). In the graph above, the IFAN is operating in Auto Fan speed mode. Therefore, the IFAN speed changes automatically according to the (RT - SPT). -

7-3 Auto (Cool/Heat) Mode Operation (RT - SPT) [ COMP & OFAN Auto Heat Mode Auto Cool Mode Auto Heat Mode In Auto Mode, the unit switches between the Auto Cooling Mode and Auto Heating Mode automatically to maintain the room temperature (RT) at the set point temperature (SPT). -

7-4 Dry Mode Operation (RT - SPT) [ Time [min] DRY-ON DRY-OFF IFAN 5 minutes COMP ON time COMP & OFAN 3.5 min Max 15 minutes Max 15 minutes 6 min (Note 2) (Note 1) In Dry Mode, the unit operates in a mild cool mode to lower the humidity of the room. In order to maintain a high efficiency in the drying operation without over lowering the room temperature excessively, the Dry Mode is different from the Cool Mode in two ways. -
