Example 1: overview of the regulating steps with the coolant capacity given in percentages (x = active)
Switching compressors on:
If two or more steps give the same resultant capacity, the step selected first will be the one that
requires the fewest compressors to be switched off. If that still leaves more than one equal step,
the one selected will be the one with the shortest switch-on delay. If there are then still equal
steps, the one with the fewest operational hours will be selected. If that still does not yield one
unique step, then the first one in sequence will be switched on.
Switching compressors off:
If two or more steps give the same resultant capacity, the step selected first will be the one that
requires the fewest compressors to be switched off. If that still leaves more than one equal step,
the one selected will be the one with the shortest switch-off delay. If there are then still equal
steps, the one with the most operational hours will be selected. If that still does not yield one
