Q1
The timer will not become set.
The current time display will
disappear at once.
Q2
Q3
I made a timer "reservation". But
the time setting has disappeared.
I tried to set the "sleep" timer
while the ON timer is reserved.
But it will not set itself to a desired
time. Q4
The time set in the "sleep" timer can be set with a
time up to the time set with the ON timer. If the end
time of the "sleep" timer is past the time set with the
ON timer, you cannot make that setting.
A4
Is the time not past the reserved time?
The set time disappears when the current time
reaches the reserved time.
A3
The current time
disappears 10 seconds
later. The timer set
display is given priority.
A2
Have you set the product to the current time? The
timer cannot be set unless it is set to the current
time.
A1
When set to the current
time setting, the reading
blinks for about 3 minutes.
Wireless remote control
I set the "sleep" timer during
operation.But
the indoor fan will not run (it will
not produce wind)
wind intensity will not change.
Q5
I tried to change the setting with
the "room temperature" button of
the remote control unit in vain.
Q6 A6
You cannot make this setting when the product is in "air
purification" mode. Moreover, you cannot set the product
to a desired setting when quick laundry or dew control is
being performed with the "auto" or "quick
dehumidification" button.
This occurs when the room temperature and humidity
have reached their settings during dehumidification and
the air-conditioner is in a pause. The product will begin
again to run within about 3 minutes.
The product will run with the wind speed set to a "quiet"
state.
