Memory function setting
When the unit is shut off, press the MODE button for 10
seconds to switch set values so as to decide if the unit
operating status or shut off status is memorized after a
power fail.
If the set temperature area displays "01", it means the
unit operating status or shut off status shall be memorized
after a power fail; "02" means the operating status or shut
off status will not be memorized.
Press the ON/OFF button to store the set value and exit
the setting.
Even if the ON/OFF button is not pressed, the system
will store the set value and exit the setting after 10
seconds, and return to the normal unit off display.
