Not Malfunction Of The Air Conditioner - Daikin FHQ71BUV1B Operation Manual

WHAT TO DO WHEN STOPPING THE SYS-
TEM FOR A LONG PERIOD
Turn on FAN OPERATION for a half day and dry
the unit.
• Read the operation manual that came with the
remote controller.
Cut off the power supply.
• When the main power switch is turned on, some
watts of electricity is being used even if the sys-
tem is not operating.
Turn off the main power supply switch for saving
energy.
• The display on the remote controller will vanish
when the main power switch is turned off.
Clean the air filter and the exterior.
• Be sure to replace the air filter to its original place
after cleaning. Refer to "MAINTENANCE".
8. NOT MALFUNCTION OF THE AIR
CONDITIONER
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 " " and it flashes for few sec-
onds 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.
8
• The outdoor unit is stopped.
This is because the room temperature has
reached the set temperature. The indoor unit
switches to fan operation.
II. WHEN " " IS DISPLAYED AND OPER-
ATION IS DIFFERENT FROM THE REMOTE
CONTROL DISPLAY.
This is because operating mode is controlled by a
micro computer, as shown below, depending on
the operating mode of the other connected indoor
units when using in a multi system.
• If the operating mode does not match that of
the other indoor units which are already run-
ning, the indoor unit goes into standby mode
(the fan stops and the air flow flaps become
horizontal).
The unit will go into the above mode if either cool-
ing, dry, or fan operation mode are set together
with heating mode.
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 all the indoor units run-
ning exceeds the limit, the indoor unit will go
into standby mode (fan and air flow direction
remain as set). (Only for cooling-only type.)
• If another indoor unit goes into heating mode
after cooling, the unit may go into dry mode
(fan operates whisper and the air flow flaps
become horizontal).
III.THE FAN SPEED IS DIFFERENT FROM THE
SETTING.
• Pressing the fan speed control button does
not change the fan speed.
When the room temperature reaches the set tem-
perature in heating mode, the power supply from
the outdoor unit stops and the indoor unit goes
into whisper mode (in a multi system, the fan goes
back and forth between stop and whisper).
This is to prevent the cool air from being blown
directly onto anyone in the room.
