P reheating operation is executed at the time of operation s tart and after completion
of defrosting, and at all other times, there is no operation, independent of the preheating signal.

F or the time T E after start of heating operation, defros ting will not be
executed even when the defros ting s ignal is given as input.
When the res erve cycle defrosting TA has continued for the time
shown in the table on the left, the operation advances to T B and TC
independent of the defrosting s ignal.
When the power relay becomes O N after expiration of the time TE ,
defrosting will be started immediately with input of the defros ting s ignal.
Once defrosting has been completed, the defros ting signal is not
accepted for the time T E .
When a defrosting s ignal has been given as input at the time of s top
by means of the s tart/stop s witch or at the time of OF F timer count-up,
defrosting is executed before operation stop.
The defrosting s ignal is not accepted at the time of overload input.

Other detailed specifications
1. When the room temperature ris es
within 3 minutes after thermostat
OF F 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 thermos tat ON.
2. In case of T ele. control input during
stopped ON timer, operation will be
started at that time and the timer
will be cleared.
3. In case of T ele. control input during
operation of the OF F timer, the
operation will be stopped at that time
and the timer will be cleared.
4. E ven when operation s top is
executed at the time of outside fan
OF F by overload, automatic fresh
defrosting will not be executed.
5. In case of s witching 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 s et
room temperature and the blowing
velocity will be according to the
remote control signal. T he same
applies for s witching from "Heating"
to "Automatic" heating.
6. In cas e of switching from "S ensor
dehumidification" operation to
"C ooling", as it is when the
thermostat is ON. 3 min delay will
not be entered. However, the s et
room temperature and the blowing
velocity will be according to the
remote control signal.
The same applies for s witching from
"C ooling" to "S ens or dehumidifica-
tion". T he same also applies for
"Automatic" s ensor dehumidification,
cooling "S ens or dehumidification",
"C ooling".
7. T he filter sign lights after operation
of the indoor fan for 100 hours . T he
time is cleared by the filter switch.
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 60 minutes of defrosting
prohibition are counted from
Thermostat ON after start/stop
switch ON. W hen the thermos tat is
OF F at the time of start/stop s witch
ON, the 60 minutes will be counted
from the time of thermos tat ON. The
initial OF F time is not counted.
C ounting starts when the thermos tat
becomes ON, and the count then
continues even if the thermos tat
becomes OF F .
11. In case of s witching 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 s hown
below when the overload input
disappears.
(1) When previously the
defrosting signal existed
without overload input,
defrosting will s tart
immediately.
(2) In cases other than the
above, defrosting will be
executed with a defrosting
signal in the condition without
overload input.
