10.2.3 Load-dependent by controller
The pump can be switched on load-dependent by the controller (see section 15.1.1
"Assign aggregates to sequences").
The co
ntrollers can be used for up to three wiring connections; maximum selection
applies. The switch-on and switch-off points can be entered via the settings "Load-
dependent ON" and "Load-dependent OFF". In normal use, we recommend
switching on the pump at 5% load and switching it off at 0% load.
