As shown below, the upper limit of the revolution frequency is restricted. However B zone is assumed as C zone for 6 minutes and after when the compressor activated. In defrost operation, the control value of Tc is shifted by 6°C. In D and E zones, the priority is given to air volume selection setup of remote controller.

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 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 [L] mode.

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