Display/Parameter
Inputs/Outputs: Indicates the state of the different entries/exits.
Master: indicates the type of data displayed; the displays can be:
• Analogue inputs;
• Digital inputs;
• Digital outputs;
05: indicates the status of the flow switch positioned on the
evaporator, the status of this input can be one of the following:
• Closed = normal functioning;
• Open = minimum water flow rate threshold exceeded at the
evaporator (Flow switch alarm);
06: indicates the status of the compressor magnet circuit breaker
indicated, the status of this input can be one of the following:
• Closed = normal functioning;
• Open = the compressor load has exceeded the maximum
threshold (Compressor magnet circuit breaker alarm);

01: indicates the status of the high pressure switch, mounted
on the cooling circuit indicated. The status of this component
can be one of the following:
• Closed = normal working state;
• Open = maximum pressure threshold exceeded
(HIGH PRESSURE alarm);
02: indicates the status of the low pressure switch, mounted
on the cooling circuit indicated. The status of this component
can be one of the following:
• Closed = normal working state;
• Open = minimum pressure threshold exceeded
(LOW PRESSURE alarm);
