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 5. ERROR MESSAGE If sensor is failed, the red LED on receiver flashes quickly. To solve the problem by checking the connection of sensor or replacing a new sensor. If the orange led freashes quickly , it means the internal circuit is failed.
