the former position after pushing the button.
It does not restart immediately because a safety device operates to prevent overload of the system.
After 3 minutes, the system will turn on again automatically.
zIf the reception beep is rapidly repeated 3 times (It sounds only twice when operating normally.)
Control is set to the optional controller for centralized control.
zIf the defrost lamp on the indoor unit’s display is lit when heating is started.
This indication is to warn against cold air being blown from the unit. There is nothing wrong with the
equipment.
II. THE UNIT STOPS ONCE IN A WHILE
zThe remote controller indicates “U4” and “U5”, the unit stops. Within several minutes the unit
restarts.
Due to electrical noise other than that from the air conditioner, the communication between the units is
cut off and the unit stops.
When the noise is gone, the unit automatically restarts.
III. NO CHANGEOVER IS AVAILABLE BETWEEN HEATING AND COOLING MODES
zThe indoor unit mak es a “PEEE” receiving sound.
When operation changeover is under control, the control is set to the mode that cannot be carried out.
IV. AIR FLOW RATE CANNOT BE OBTAINED AS SET
zEven if the air flow rate adjusting button is pressed, the air flow rate does not change.
When the room temperature reaches the indoor unit set temperature, the outdoor unit stops and the air
flow rate of indoor unit drops to the minimum.
This is to avoid the cold air from getting in contact with the people in the room.
V. AIR DISCHARGE DIRECTION IS NOT AS SET
zThe remote controller indication and the air discharge direction is not the same.
Air discharge direction swing is impossible.
Because it is controlled by microcomputer. Refer to “AIR FLOW DIRECTION ADJUST” on page 56.
VI. ONLY A PART OF INDICATION SHOWS
zEven if the unit is operated, only the operation indication shows, or even if the indication shows,
soon after, the indication other than that for operation disappears.
The corresponding indoor unit is that for multi-system and the remote controller is set to the multi-
system.
VII.NO INDICATION SHOWS OR ALL INDICATION SHOW
zWhen the remote controller button is pressed.
The battery is dead.
VIII.INSUFFICIENT COOLING

Multiple setting Remote controller display
A: Standard All items displayed.
When operation changeover, temperature setting or the
like is carried out from the remote controller, the indoor
unit rejects the instruction.
(Signal receiving sound “peeh” or “pick-pick-pick”)
As a result, a discrepancy between the operation state of
the indoor unit and the indication of the remote controller
display occurs.
b: Multi System Operations remain displayed
shortly after execution.
Since the indication of the remote controller is turned off,
no discrepancy such as mentioned above occurs.
