Compressor Rotational Speed Control
1. When power is turned on, rotational speed is fixed 42 (r/s) for 10 minutes.
2. The use rotational speed.
Compressor rotational speed decided by the ATC temperature.
• Each ATC temperature condition, for the first step, it starts the lowest rotational speed of available range.
• If the temperature difference is big between PCC and FCC, the rotational speed changes one rank up.

Compressor Starting Control
The compressor is not start while waiting timer is operating.
And when power is turned on, compressor starting control is not available.
