9. Symptoms that are not air
conditioner troubles
Following symptoms are not air conditioner troubles:

9.1 The system does not operate

• The air conditioner does not start immediately
after the ON/OFF button on the user interface is
pressed. 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 "Under Centralized Control" is displayed on
the user interface and pressing the operation
button causes the display to blink for a few
seconds indicating that the central device is
(b)
controlling the unit. The blinking display
indicates that the user interface cannot be used.
• The system does not start immediately after the
power supply is turned on. Wait one minute until
the microcomputer is prepared for operation.

9.2 Cool/Heat cannot be changed over

• When the display shows "
under centralized control), it shows that this is a
slave user interface.
• When the Cool/Heat selector is installed and
the display shows "
centralized control). This is because cool/heat
changeover is controlled by the Cool/Heat
selector. Ask your dealer where the Cool/Heat
selector is installed.
