The power relay is
delayed by 2 seconds
from the start of
thermostat operation.
●
““HI””, ““MED””, or ““LO”” operation is
executed according to the thermostat
signal. (Refer to ““Thermostat operation””.)
●
““LO”” and ““Stop”” are repeated according to the thermostat signal, independent of the setting.
Notes:
●
Forced operation by start/stop button ON is executed even with thermostat OFF.
●
The room temperature 30 sec after operation start, minus 0.66 deg, becomes the se temperature.
●
When the room temperature is 16°C or lower, 16°C becomes the set temperature.
●
The other operations are the same as for (1).
(2) Set temperature is higher than room temperature.

Other detailed speci  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
A L A H in the same way as at
the time of thermostat ON.
2. In case of switching from ““Sensor
dehumidi
 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 dehumidi  cation””.
3. The  lter sign lights after operation of the
indoor fan for 200 hours. The time is cleared
when the ““ (AUTO SWING)”” button
is pressed while the device is on ““STANDBY
MODE””.
4. 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.
