The end user is not allowed to access very many parameters in the controller. This fact does however
demand more of the installer in terms of adapting the controller settings to meet the needs of the end user,
as well as adapting the controller settings to operate in harmony with the remote refrigeration installation.
In terms of knowing the Gram factory settings which have been made to the controller installed, the
following appendixes have been added at the end of this document (see table of contents)
• Appendix I related to Gram settings of the Danfoss AKCC-550A controller.
• Appendix II related to Gram settings of the Carel MPX-pro controller.
These appendixes show all the settings which have been made as a default, in order to make sure the
product will run as desired when delivered. The hardware configuration of the cabinet does however allow
the cabinet to run as:
• A standard U-cabinets (solid door) setpoint +12 to -25°C (default) To be adapted to customer needs
and system limitations.
• As a glass door refrigerator KG-cabinet +12 to +2°C (default not to be changed for lower settings)
• As a Glass door freezer (only MIDI) -5 to -22°C. (Default)
IMPORTANT:
Know that refrigerator cabinets with glass door (KG), cannot be changed to run as freezers, due to the fact
that the refrigerator glass doors, does not include a heating element needed on the freezer in order to avoid
condensation.
It is very important always to check all the parameters in the controller, in order to verify the settings in
terms of correctness and suitability related to demands and refrigeration installation. The settings which are
made from the factory are not necessarily suitable for the system which the cabinet is to be integrated into.
