Hi,

I have some units under my maintenance contract with Carel PCO controller witch are experiencing maintenance alarms.
Since these are abandoned by original installer (they gone out of businesses), I am unable to find or acquire original documentation.
Unit in question are from Thermocold and Emicon.
I would appreciate if anyone know what are maintenance passwords of those manufacturers, since original Carel maintenance password is not functioning there.

Is it possible to order Carel EEPROM chip with software unlocked, like in Carel PCO available at stores, and only change parameters according to application ( i have no problem to parameter it myself)?
I have two fully functioning PCO boards but with locked software. If I could buy only EEPOM chip and make changes in parameters it would be much cheaper for customer to go that way!

Yes, it is tried 1000 and 0123 and 1234!

Also, unit in question have 2 PCO boards. One is master and second one is slave.

When we enter 1234 password on the screen appears question something like second (level?) password!
It appears that 1234 is OK for first level or something like that, but another password is required for 2nd level.
We need to reset compressor maintenance alarm.

If I remember right there are three different passwords user,maintenance and manufacturer, your best bet is try and contact emicon as it is there software passwords and not carels
