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.

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 Specifications
Table 2 Sensor operation values
Other detailed specifications
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 Tele. control input during
stopped ON timer, operation will
be started at that time and the timer
will be cleared.
3.
In case of Tele. control 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
dehumidification” 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 dehumidifica-
tion”. The same also applies for
“Automatic” sensor dehumidifica-
tion, cooling “Sensor dehumidifica-
tion”, “Cooling”.
7.
The filter sign lights after operation
of the indoor fan for 200 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 flashing), 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.
