• 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).

• 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

shifted at the same time.
However, correction is possible
only in cooling operation mode,
but not in “Sensor dehumidific-
