6. Timed running 
.
 Set the time duration according to the time difference between the clock for 
timing and the current clock 
. In timing mode, the display panel will flash the light at fixed times 
6-0-1. Timed OFF 
When this function is set, operation modes on the panel display will not change. 
The timing icon will show and the operation stops when the set time comes. 
6-0-2. Timed ON

7. Automatic running 
7-1.
 Automatic running mode 
Under this
 mode, the MCU will choose the work mode according to the room 
temperature so as to keep the set termperature ( set 23
℃
 for heating mode and 
26
℃
 for cooling mode) 
When the unit is powered on for the first time and the the room termperature is equal to or 
below 23
℃
, it will start the heating mode or the cooling mode when the room temperature is 
higher than 23
℃
 
Enter into the heating mode and follow the heating process(supposed temperature 23
℃
). 
When the temperature is high enough to stop the compressor, the compressor stops and there
