Adjustment - Manual operation
All control modes, which are selected via the setting assistant, can be overridden with the functions of manual operation OFF, MIN, MAX, MANUAL.
DANGER
The pump can start despite the “OFF” function
The “OFF” function is not a safety function and is no replacement for disconnecting the power supply for maintenance work. Functions such as pump kick can start up the pump despite the “OFF” function being set.
- Always disconnect the pump from the power supply before carrying out any work!
Manual operation functions can be selected in the menu 
“Settings”→ “Manual operation”
