4-6. Remote 14 Receptacle Information

This unit automatically senses when a remote control is connected to the remote 14 receptacle. After connecting a
remote control, the unit will automatically adjust output control to a primary/secondary configuration. In this
configuration, the AMP ADJUST control on the unit becomes the primary and sets the maximum amperage output of
the unit. The remote control becomes the secondary and provides an amperage range adjustment of 0 to 100% based
on the AMP ADJUST control setting.
