malfunction
I. The system does not operate
•
The system does not restart immediately after the ON/
OFF button is pressed.
If the OPERATION lamp lights, the system is in normal
condition.
It does not restart immediately because a safety device
operates to prevent overload of the system. After 3
minutes, the system will turn on again automatically.
•
The system does not restart immediately when
TEMPERATURE SETTING button is returned to the
former position after pushing the button.
If the OPERATION lamp lights, the system is in normal
condition.
It does not restart immediately because a safety device
operates to prevent overload of the system. After 3
minutes, the system will turn on again automatically.
•
The system does not start when the display shows
“
” (UNDER CENTRALIZED CONTROL) and it
flashes for few seconds after pressing an operation
button.
This is because the system is under centralized control.
Flashes on the display indicates that the system cannot be
controlled by the remote control.
•
The system does not start immediately after the power
supply is turned on.
Wait one minute until the micro computer is prepared for
operation.
•
The outdoor unit is stopped.
This is because the room temperature has reached the set
temperature. The indoor unit switches to fan operation.
II. The display shows “
” (UNDER
CENTRALIZED CONTROL)
and the unit operates in
a mode different to what is shown on the
remote control display.
When using a unit in a multi system, the operation
condition of that unit is controlled by a micro computer as
described below, according to the operation condition of
other indoor units connected to the system.
•
If the operation mode does not match other indoor units
that are already running, the indoor unit will assume the
STANDBY state (the fan is stopped and the air flow flap is
positioned horizontally).
If HEATING mode is set together with COOLING, DRY or
FAN mode, the above mentioned condition will occur.
NOTE
•
Normally, the operation mode in the room where the unit is
first run is given priority, but the following situations are
exceptions, so please keep this in mind.
a. If the operation mode of the first room is FAN Mode,
then using Heating Mode in any room after this will give
priority to heating. In this situation, the air conditioner
running in FAN Mode wil go on standby.
b. With the Priority Room Setting active.
