Notes:
● 60 minutes after the sleep key is switched on,
sleep operation
is started.
● When the sleep key is switched on during OFF timer operation,
the OFF timer will be canceled.
● When the sleep key is switched on during OFF timer operation, the OFF timer will be cancelled.
● When the sleep key is switched on during ON after a timer reservation, sleep operation will be started.
Notes:
● Even when the preheating signal is not given as input, heating operation is started when 3 minutes have
passed for T.
● Preheating operation is executed at the time of operation start and after completion of defrosting, and at all
other times, there is no operation, independent of the preheating signal.

●
For the time TE after start of heating operation, defrosting will not be executed
even when the defrosting signal is given as input.
●
When the reserve cycle defrosting TA has continued for the time shown in the table
on the left, the operation advances to TB and TC independent of the defrosting
signal.
●
When the power relay becomes ON after expiration of the time TE, defrosting will
be started immediately with input of the defrosting signal.
●
Once defrosting has been completed, the defrosting signal is not accepted for the
time TE.
●
When a defrosting signal has been given as input at the time of stop by means of
the start/stop switch or at the time of OFF timer count-up, defrosting is executed
before operation stop.
●
The defrosting signal is not accepted at the time of overload input.

Table 1 Specifi cations
Table 2 Sensor operation values
Other detailed specifi cations
1. When the room temperature rises
within 3 minutes after thermostat OFF
during cooling operation with automatic
velocity, the blowing velocity changes
in the order of S → L → H in the
same way as at the time of thermostat
ON.
2. In case of Temporary switch input
during stopped ON timer, operation
will be started at that time and the
timer will bee cleared.
3. In case of Temporary switch input
during operation of the OFF timer, the
operation will be stopped at that time
and the timer will be cleared.
4. Even when operation stop is executed
at the time of outside fan OFF by
overload, automatic fresh defrosting
will not be executed.
5. In case of switching to “Heating”
during “Automatic” heating operation,
the operation will be continued as it is
when the thermostat is ON. 3 min
delay will not be entered. However,
the set room temperature and the
blowing velocity will be according to
the remote control signal. The same
applies for switching from “Heating”
to “Automatic” heating.
6. In case of switching from “Sensor
dehumidifi cation” operation to “Cooling”,
as it is when the thermostat is ON.
3 min delay will not be entered.
However, the set room temperature and
the blowing velocity will be according
to the remote control signal.
The same applies for switching from
“Cooling” to “Sensor dehumidifi cation”.
The same also applies for “Automatic”
sensor dehumidification, cooling
“Sensor dehumidifi cation”, “Cooling”.
7. The fi lter sign lights after operation of
the indoor fan for 100 hours. The time
is cleared when power switch set to
OFF and ON again.
8. After entry into trouble mode (when
the indication lamp is fl ashing), the
rapid feed mode can not be changed.
9. When operation by nice temperature
reservation is executed during sleep
operation, normal operation will be
continued, and the advance time
becomes the temperature difference
between the set temperature without
sleep shift and the room temperature.
10. The 50 minutes of defrosting prohibition
are counted from Thermostat ON
after start/stop switch ON. When
the thermostat is OFF at the time of
start/stop switch ON, the 60 minutes
will be counted from the time of
thermostat ON. The initial OFF time
is not counted. Counting starts when
the thermostat becomes ON, and
the count then continues even if the
thermostat becomes OFF.
11. In case of switching from “Heating” the
reversing valve is held for 3 minutes.
12. The defrosting signal is not accepted
with overload input, and the operation
becomes as shown below when the
overload input disappears.
(1) When previously the defrosting
signal existed without overload
input, defrosting will start
immediately.
(2) In cases other than the above,
defrosting will be executed
with a defrosting signal in the
condition without overload input.
