When Tai
≥
Tset, entering auto cooling mode;
When Tai
<
Tset, entering auto heating mode.
5.2 Auto cooling mode is as the same as the cooling mode. After the thermostat is OFF for 15 minutes, if
Tai+ 1+Tcomp2
<
Tset, the unit will enter auto heating mode, or the unit will still stay at auto cooling mode
and stop when it reaches the set temperature; while the indoor motor will be at low speed.
5.3 Auto heating mode is as the same as the heating mode. After the thermostat is OFF for 15 minutes, if
Tai
≥
Tset+1 +Tcomp1, the unit will enter auto cooling mode, or the unit will still stay at auto heating mode;
5.4 In this mode, the Sleep function is available, run as cooling sleep in cooling mode and as heating
sleep in heating mode. Once sleep mode is set, the mode will not change after the unit stops for 15
