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 commanded
frequency changes every 30 seconds while operation is
performed in [J] zone.
In [K] zone, time counting is interrupted and the opera-
tion 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.

• 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.
