Instruction SiEBE18-526
236 System Configuration
• The system does not start when the display
shows “ ” (UNDER CENTRALIZED
CONTROL) and it flashes for few seconds after
pressing an operation button.
This isbecause the system isunder 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 isbecause the room temperature has
reached the set temperature. The indoor unit
switches to fan operation.
II. WHEN “ ” (UNDER CENTRALIZED CONTROL)
IS DISPLAYED AND OPERATION IS DIFFERENT FROM
THE REMOTE CONTROL DISPLAY.
This isbecause 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 running,
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
cooling, 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 following
situationsare 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 will go on standby.
b With the Priority Room Setting active
Cont
act your Daikin de
aler for the operation that
corresponds to your system.
• If the total capacity of all the indoor units
running exceeds the limit, the indoor unit will
go into standby mode (fan and air flow direc-
tion 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
temperature in hea
ting mode, the power supply
from the outdoor unit stopsand the indoor unit
goes into whisper mode (in a multi system, the fan
goesback and forth between stop and whisper).
This is to prevent the cool air from being blown
directly onto anyone in the room.
IV. AIR BLOW DIRECTION IS NOT AS SPECIFIED.
• Actual air blow direction is not as shown on
the remote control.
• Automatic swing setting does not work.
Refer to “AIR FLOW DIRECTION ADJUST”.
V. WHITE MIST COMES OUT OF A UNIT
• When humidity is high during cooling opera-
tion (In oily or dusty places)
If the inside of an indoor unit is extremely
contaminated, the temperature distribution inside
a room becomesuneven. It is necessary to clean
the inside of the indoor unit. Ask your Daikin
dealer for details on cle
aning the unit. This
operation requires a qualified service person.
• When the system is changed over to HEATING
OPERATION after DEFROST OPERATION.
Moisture generated by DEFROST becomes
stea
m and exists.
VI. NOISE OF AIR CONDITIONERS
• A ringing sound after the unit is started.
This sound is generated by the temperature
regulator working.
It will quiet down after about a minute.
• A continuou
s flow “Shuh” sound is heard
when the systems is in COOLING or
DEFROST OPERATION.
This is the sound of refrigerant gas flowing
through both indoor and outdoor units.
• A “Shuh” sound which is heard at the start or
immediately after the stop of operation or
which is heard at the start or immediately after
the stop of DEFROST OPERATION.
This is the noise of refrigerant caused by flow stop
and flow change.
• A continuous flow “Shah” sound is
heard
when the system is in COOLING OPERATION
or at a stop.
The noise is heard when the drain pump is in operation.
• A “Pishi-pishi” squeaking sound is heard
when the system is in operation or after the
stop of operation.
Expansion and contraction of plastic parts caused
by temperature change makes this noise.
