1) The cooling operation (including Dry operation) is

performed as follows based on the detected tempera-
ture of Tc sensor or Tcj sensor.
When [J] zone is detected for 6 minutes (Following
figure), the commanded frequency is decreased from
the real operation frequency. After then the com-
manded frequency changes every 30 seconds while
operation is performed in [J] zone.
In [K] zone, time counting is interrupted and the
operation is held.
When [I] zone is detected, the timer is cleared and the
operation returns to the normal operation.
If the commanded frequency becomes S0 because the
operation continues in [J] zone, the return temperature
A is raised from 5°C to 12°C until [I] zone is detected
and the indoor fan
operates with [M] mode.

In heating operation, the freeze-preventive control
works if 4-way valve is not exchanged and the condi-
tion is satisfied. (However the temperature for J zone
dashing control is changed from 2°C to –5°C.)

1) The heating operation is performed as follows based on

the detected temperature of Tc sensor or Tcj sensor.
• When [M] zone is detected, the commanded fre-

quency is decreased from the real operation fre-
quency. After then the commanded frequency
changes every 30 seconds while operation is per-
formed in [M] zone.

• In [N] zone, the commanded frequency is held.
• When [L] zone is detected, the commanded fre-

quency is returned to the original value by approx.
6Hz every 60 seconds.

NOTE :
When the operation has started or when Tc or Tcj became
lower than 30°C after start of the operation, temperature
is controlled between values in parentheses of A and B.
