The controllers are control units for setting refrigeration functions and operating data. They allow readouts of system messages
and diagnostic data.
The controllers have a service interface at which different configurations are possible.
They also have a connection for collective fault signals.

Cooling units with a Standard-Controller (SC) have an indicator unit with a green LED-light (1).
The indicator unit is on the unit cover. Steady lighting of the green LED-light (1) when mains voltage is applied indicates fault-
free operating mode.
The LED light (1) starts flashing in the event of an operating fault or malfunction. For details of error messages, see "Error
