In the case of a two-circuit condenser, the setting will take as the reference the highest condensing pressure, or the
lower evaporation pressure, giving priority to the circuit requiring more resources. Both circuits have the same
reference set-point (PR02). In case of failure of one of the two pressure probes, the adjustment is made only based on
the circuit with the active probe, and a failed probe warning is returned. Parameter PG03 defines the number of
condenser circuits, and enables the input of the second AI2 pressure probe.
