Fan : If selecting continuous fan mode, the green LED flashes.
Dehumidifying : If selecting dehumidifying mode , the 3 - way valve works as 10 minutes
on and 10 minutes off. In this cycle , the fan speed turns into low speed.
If the Room temp. is lower than 16 ,the 3 - way valve contact remains off.
Sleep Mode : In cooling mode , when this function is set , then the temperature will go
up 1 after one hour of setting ( in heating mode , it will go down 1 ) ;
then at the second hour , the temperature will go up another 1 ( in
heating mode , it will go down another 1 ) ; then this final temperature
will be remained.
( The highest limitation of setting temperature is 30 and the lowest
limitation is 16 )
Setting Reservation clock :
After pre - setting timer for operation , the controller will be
power - on or power - off according to the pre - set time.
The workable distance of the receiver : as below illustration
