The following symptoms do not indicate air condi-
tioner 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 sys-
tem. 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 sys-
tem. 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 con-
troller.
• The system does not start immediately after
the power supply is turned on.
Wait one minute until the micro computer is pre-
pared for operation.
• The outdoor unit is stopped
This is because the room temprerature has
reached the set temprerature. The indoor unit
switches to fan operation.
II. The display shows “
” (UNDER CEN-
TRALIZED CONTROL) and the unit operates
in a mode different to what is shown on the
remote controller display.
When using a unit in a multi system, the opera-
tion condition of that unit is controlled by a micro
computer as described below, according to the
operation condition of other indoor units con-
nected 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 hori-
zontally).
If HEATING mode is set together with COOLING,
DRY or FAN mode, the above mentioned condi-
tion will occur.
NOTE
• Normally, the operation mode in the room where
the unit is first run is given priority, but the follow-
ing 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 sit-
uation, the air conditioner running in FAN
Mode will go on standby.
b. With the Priority Room Setting active.
Contact your Daikin dealer for the operation
that corresponds to your system.
• If the total capacity of operating indoor units
exceeds the limit, the indoor unit will assume the
STANDBY state (FAN and AIR FLOW DIREC-
TION will be left as set). (This only applies to
cooling only type.)
• If another indoor unit commences a HEATING
operation after this indoor unit is running in
COOLING mode, this indoor unit may switch to
DRY operation (fan on low, air flow flap set at hor-
izontal).
