To restore defaults

all custom settings. It is recommended to restore the factory defaults only under the guidance of Carrier Control
Systems Support.
To erase volatile memory data and restore factory default configuration settings:
1 Turn off the AppController's power switch.
2 Put the Factory Defaults jumper on.
3 Turn on the AppController's power switch.
4 Remove the Factory Defaults jumper.
