Over ride codes for Carrier Aqua Snap Chillers

[GDH2012]

Does anyone know of a high level over ride code that would enable access into a Carrier Aqua Snap chiller. Generic pass codes do not work, as Carrier service technicians have changed access codes.

Is it the pro dialog? If so, get a cup of tea and start inputting codes, can only be a number between 0 and 150!! Had to do similar on a site last week,
