To restore factory defaults
CAUTION
This erases all archived information and user-configuration settings. You will have to reconfigure
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 Carrier® ChillerVu™'s power switch.
2
Make sure the address switches are not set to 0, 0.
3
Hold down the controller’s
Factory Defaults
button while you turn its power on.
4
Continue to hold down the
Factory Defaults
button until the controller displays
8
and then the chase pattern,
then release the button.
5
Turn on the Carrier® ChillerVu™'s power switch.
CAUTION
If you have a CCN network and you restore factory defaults, you must download to the Carrier®
ChillerVu™ from the i-Vu® application and NOT upload it. Uploading results in losing your CCN communication.

a Module Status report (Modstat) under
