The power relay is
delayed by 2 seconds
from the start of
thermostat operation.
(1) In case of “Automatic” mode
Note:
●
The min. ON time of the power relay
is 3 minutes, and the min. OFF time
also is 3 minutes.
(2) In other modes than “Automatic”
Same as above (but operation is
made with the velocity set at the
time of operation start).
●
“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 set
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).

●
The operation mode at the
start of operation differs as
shown below according to
the room temperature.
●
A shift is not accepted at the
time of operation start.
●
There is no switching between
modes after start of operation.
●
When the operation is started
again within 20 min. after
stop with the start/stop button,
operation will be executed in
the previous mode.
●
The operation details are the
same as for each operation mode.
●
The set temperature is set with
the room temperature
adjustment button. Correction
by ,±3°C is possible with.
At this time, the operation mode
judgement temperature also is
shifted at the same time.
However, correction is possible
only in cooling operation mode,
but not in “Sensor dehumidi
fi ca-
tion” mode.
(2) Set temperature is higher than room temperature.
(1) When the set temperature is lower than the room
temperature.
