EEPROM Write Failure on VariTrac CCP III

Issue:

EEPROM Write Failure on VariTrac CCP III

Resolution:

 

Upgrade the firmware in the VariTrac CCP3 to the latest image 4.200.344. This corrects the EEPROM write fail error and quarantines the bad blocks that were being overwritten so the controller will have a normal life time.

 

 

Replace the CCP (and make sure to upgrade the image if not running the latest and greatest).

Facts:

• VariTrac III Central Control Panel (CCP)
• The CCP appears able to run the system including the rooftop. Fan is on etc. EEPROM failure occurred after attempting to make name changes to the panel and zones. Cycling power would clear EEPROM Write Failure diagnostic but previously entered name changes also disappeared. AHU's were occupied but Operating modes were off and the fan would not turn on.
