Three groups of chillers can be defined in the „GPA_GroupSelect“ module. The number of chillers in each group is defined by the parameters CFG-01 to CFG-03.
Whether the group is enabled during free cooling depends on the parameters FRCG-01 through FRCG-03.
The sequence of the groups can be defined by parameter SEQ-01.
