TIME:

 Press this to display working hours and total working time. 

•  Once the unit is running, the display will show the humidity setting 

(left) and current humidity (right). Humidity setting can be changed by 

pressing “Up” or “Down.” 

•  Time settings are based on minutes. For example, if the display shows 

“0000:50,” this means that the unit has worked for 50 minutes since 

powered on. If you want to view the total working time, press “T” again 

and the display will show this for 10 seconds, then return automatically 

to the original working hours. (Pressing “T” before the 10 seconds will 

return the display to the original working hours.)

•  If the unit is powered on but not in operation, the LED will not display 

anything. If “T” is pressed once, the working hours from the previous 

time the unit ran will display for 10 seconds. Within the 10 seconds, if 

“T” is pressed again, the total working time will display for 10 seconds. 

If there is no action within those 10 seconds, the LED will automatically 

shut off.

•  If “T” is pressed when LED displays the total working time, the LED 

will shut off immediately. The current working time will be deleted by 

pressing and holding down “T” for 5 seconds; the time will be reset, but 

the deleted time will be added into the total working time.

NOTE: The total working time cannot be deleted. If the time is beyond 

the range of what the LED can show, it will be deleted and restart  

from zero.
NOTE: If a power outage occurs while the unit is powered on, the unit 

automatically resumes operation at the most recent settings when power 

is restored.
