Operation Manual 215
8. Following Symptoms are not Air Conditioner
Troubles
8.1 The System does not operate
!
The air conditioner does not start immediately after the ON/OFF button on the remote
controller is pushed.
If the operation lamp lights, the system is in normal condition.
To prevent overloading of the compressor motor, the air conditioner starts 5 minutes after it
is turned ON again in case it was turned OFF just before. The same starting delay occurs
after the operation mode selector button was used.
!
If “Centralized Control” is displayed on the remote control and pressing the operation
button causes the display to blink for a few seconds.
This indicates that the central device is controlling the unit.
The blinking display indicates that the remote control cannot be used.
!
The system does not start immediately after the power supply is turned on.
Wait one minute until the micro computer is prepared for operation.
8.2 Cool/Heat cannot be Changed Over
!
When the display shows “ ” (changeover under control), it shows that this
is a slave remote controller.
!
When the cool/heat changeover remote control switch is installed and the display
shows “
” (changeover under control).
This is because cool/heat changeover is controlled by the cool/heat changeover remote
control switch. Ask your Daikin dealer where the remote control switch is installed.
8.3 Fan Operation is Possible, but Cooling and Heating do
not Work
!
Immediately after the power is turned on.
The micro computer is getting ready to operate. Wait 10 minutes.
8.4 The Fan Strength does not Correspond to the Setting
!
The fan strength does no change even if the fan strength adjustment button in
pressed.
During heating operation, when the room temperature reaches the set temperature, the
outdoor unit goes off and the indoor unit changes to whisper fan strength.
This is to prevent cold air blowing directly on occupants of the room.
The fan strength will not change even if the button is changed, when another indoor unit is in
heating operation.
8.5 The Fan Direction does not Correspond to the Setting
!
The fan direction does not correspond to the remote control display.
The fan direction does not swing.
This is because the unit is being controlled by the micro computer.
