• The system does not restart immediately after the ON/

OFF button is pressed.

If the OPERATION lamp lights, the system is in normal con-
dition.

ates to prevent overload of the system. After 3 minutes, the 
system will turn on again automatically.

• The system does not restart immediately when TEM-

PERATURE SETTING button is returned to the former 
position after pushing the button.

If the OPERATION lamp lights, the system is in normal con-
dition.
It does not restart immediately because a safety device oper-
ates to prevent overload of the system. After 3 minutes, the

• The system does not start when the display shows 

” (UNDER CENTRALIZED CONTROL) and it 

flashes for a few seconds after pressing an operation 
button.

anyone in the room.
