when thermo ON.
2. If “cooling” is selected during “sensor
dehumidifi cation” operation the operation
continues as it is with the thermo ON.
The 3 minutes delay is not started. The
set temperature and fan speed depend
on the remote control signal.
It is same for “cooling” – – – – “sensor

3. The filter sign lights after 200 hours
operation of the room fan. The lamp goes
out when the POWER SWITCH set to
OFF and ON again.
4. After the failure mode is started (indicator
lamp fl ickering), rapid mode changing
cannot be done.
5. If the operation is made by the nice
temperature reservation during the
sleep operation, the normal operation
continuously occurs, and for the advance
time, the temperature difference between
the set temperature without sleep shift
and “room temperature” is used.

● Operation starts in advance so that the room temperature reaches
the preset value at the set time.
● The operation time is obtained as follows depending on the room
temperature when operation starts.
(1) Calculation method of the moved-up time.
Moved-up time (MT) = Moved-up time depending on the temperature
difference (OT) + compensation time (HT).
MT is at least 1 minute if OT is not zero.
Heating Cooling
(MT) 00 ~ 60 min. 00 ~ 60 min.
(OT) 00 ~ 60 min. 00 ~ 60 min.
(HT) –60 ~ 60 min. –60 ~ 60 min.
Obtain OT (moved-up time depending on the temperature difference)
from the table below.

❈ The preset temperature value shown above does not
include any shift value.
(2) Compensation
1 The “Attained” state is monitored and a “Not attained” check is
done to revise the compensation time (HT).
“Attained” monitor
Continuously monitored during “NICE TEMPERATURE” operation.
(Heating)
When the room temperature < Set value + compensation shift,
it is regarded to be “attained” and 5 minutes are reduced from
the compensation time.
(Cooling)
When the room temperature < Set value + compensation shift,
it’s operated same as above.
“Not attained” check
Performed once when the “NICE TEMPERATURE” timer is completed.
(Heating)
When the room temperature < Set value + compensation shift
1°C, it is regarded to be “Not attained” and 5 minutes are added
to the compensation time.
(Cooling)
When the room temperature > Set value + compensation shift
+1°C, it’s operated same as above.
❈ If the room temperature is within +1°C from the set value +
compensation shift, compensation is not done.
