5. OFF via messages with plant stop (only for pumps switched on directly via
operating mode)
6. ON via switch-off delay
7. OFF via stop conditions (1+2)
8. ON via start conditions (1+2)
9. ON by outside temperature
10. On by pump kick
11. Load-dependent ON
12. Preselection in normal operation for pumps switched on directly by the
