12
Equipment emits odor.
Room smell and cigarette odors
accumulated inside the indoor unit are
discharged with air. Inside of the indoor
unit must be cleaned.
13
Flap operates when power is turned on.
It is normal. The flap initializes for accurate
positioning.
14
Change of operation mode causes flap to
move.
It is normal. There is a control function that
moves the flap when operation mode is
changed.
15
Fan operates in “M” mode during heating
even if remote controller is set to “Low.”
It is normal. It is caused by the activation of
the overload control (airflow shift control).
16
Flap automatically moves during cooling.
It is normal. It is caused by the activation of
the dew prevention function or ceiling
soiling prevention function.
17
Indoor unit fan operates in “L” mode for 1
minute in microcomputer-controlled dry
mode even if compressor is not operating.
It is normal. The monitoring function
forcibly operates the fan for one minute.
18
In simultaneous ON/OFF multi-system
setup, indoor unit (sub) does not operate in
sync with the other indoor unit (main).
(Flat, fan, etc.)
It is normal. It is caused by a signal
transmission lag.
19
Indoor unit fan operates after heating
operation stops.
It is normal. The fan operates in the “LL”
mode for 60 to 100 seconds to dissipate
the residual heat in the heater.
20
Drain pump operates when equipment is
not operating.
It is normal. The drain pump continues to
operate for several minutes after
equipment is turned off.
21
Horizontal swing sends air to different
directions in cooling and heating even if it
is set to the same position.
It is normal. The airflow direction in cooling/
dry operation is different from that in
heating/fan operation.
22
Flap remains horizontal even if it is set to
Swing.
It is normal. The flap does not swing in the
thermostat OFF mode.
23
Remote control thermostat cannot be set
with group-control remote controller.
Normal operation.
The setting of remote control thermostat is
not possible when group-control mode is in
operation.
24
When operating in remote control
thermostat, the thermostat turns off before
temperature of remote control reaches the
set temperature.
Normal operation.
The thermostat may be controlled with the
suction temperature (body thermostat),
concurrently with the set temperature.
25
When abnormality occurs with the unit with
individual remote controller in One Remote
Controller Group-control mode, the
address display of individual remote
controllers indicates “0” (zero) regardless
of the actual address setting.
Normal operation.
Address display of individual remote
controllers always indicate “0” (zero).
