AUTO FRESH DEFROSTING
AUTO OPERATION
NICE TEMPERATURE RESERVATION
INFRARED REMOTE CONTROL
After the ON/OFF button is pressed
to stop heating, the outdoor unit is
still working with the OPERATION
lamp lighting.
Fan speed does not change when
fan speed selector is changed
during auto operation.
When on-timer has been
programmed, operation starts before
the preset time has been reached.
Does “Nice temperature reservation”
function operate during dehumidifying?
Even if the same time is preset,
the operation start time varies.
Timer cannot be set.
The current time display
disappears soon.
The timer has been programmed,
but the preset time disappears.
Auto Fresh Defrosting is carried out : the
system checks the outdoor heat exchanger
and defrosts it as necessary before stopping
operation.
At this point fan speed is automatic.
This is because “Nice temperature reservation”
function is operating. This function starts
operation earlier so the preset temperature is
reached at the preset time. Operation may start
maximum 60 minutes before the preset time.
It does not work. It works only during cooling
and heating.
This is because “Nice temperature reservation”
function is operating. The start time varies
according to the load of room. Since load varies
greatly during heating, the operation start time is
corrected, so it will vary each day.
Has the clock been set? Timer cannot be set
unless the clock has been set.
The current time disappears
in approx. 10 seconds. The
time set display has priority.
Is the current time past the preset time?
When the preset time reaches the current
time, it disappears.
When the current time is
set the display flashes for
approx 3 minutes.
