Note:
1. When Auto mode is selected, unit would check room temperature first and work with fixed mode as
above accordingly. Every 6 minutes, unit would check room temperature again, running mode would
be changed according with update room temperature.
2 If working mode is changed by remote control unit has 3 minutes delay protection for compressor 2. If working mode is changed by remote control, unit has 3 minutes delay protection for compressor.
3. Fan speed selection: For Dry mode, fan speed is fixed with low speed. For Cooling, Heating and Fan
mode, fan would work with set speed.
4. Unit has protection function, including 3 minutes delay function, Anti-cold function before heating,
Over heating protection during heating function, Anti-frozen during cooling mode, E1,E2,E3,E4
protection.
