10.10 Auto mode
10.10.1 The air conditioner automatically selects one of the following operation modes: cooling,
heating or fan only according to the temperature difference between room temperature (TA) and set
temperature (TS).
10.10.2 The indoor fan blows automatically in corresponding selected mode
10.10.3 The motion of indoor fan’s blade should accord with the selected operation mode
10.10.4 One mode should be carried out for at least 15 minutes once selected. If the compressor
cannot start for 15 minutes, reselect the operation mode according to the room temp. and set temp.,
or reselect when the set temp. varies
10.11 Force cooling function
10.11.1 Select forced cooling function with the forced cooling button or the switch
