Password Bypass

Hi,
I purchased a 2001 McQuay 55 Ton WGZ Scroll Chiller from a company that is out of business. Temp settings on the unit are too high but I don't have password to change settings. Does anyone know what the manufacturers password for this unit would be? Appreciate any help.

Thanks,

Hey Moldieco
What type of controller is it using,pco or microtech??
I'm guessing microtech try 2001 or 1234..
