INPUTS/OUTPUTS menu - Compressor magnet circuit breaker flow switch digital inputs
Visualisation on unit display Index Display/Parameter
A Inputs/Outputs: Indicates the state of the different entries/
exits.
B Master: indicates the type of data displayed; the displays can
be:
• Analogue inputs;
• Digital inputs;
• Digital outputs;
C 05: indicates the status of the flow switch positioned on the
evaporator, the status of this input can be one of the following:
