Page 14: The Soft Start Function
The Soft Start Function The Soft Start function is located within the Control Menu page. The Soft Start function will operate inde- pendently on each circuit. To limit inrush current on the overall system, an inher- ent characteristic of self-regulating/limiting heating ca- ble, a proprietary Soft Start algorithm is applied during system start-up. - Page 15 6.
