Automatic
If the selection in operating line "Run priority" is "Automatic", the run priority
automatically changes weekly. Changeover occurs at the time set for motor kick.
Assign the run priority to a pump by selecting the required pump in operating line
"Run priority" if changeover by time is not what you want.
If a motor is faulty, the run priority is changed over to the other motor. After the fault
is acknowledged and reset, the same run priority as prior to the fault is resumed.
For testing, you can manually change over the run priority. To do this, select the
desired motor in operating line "Run priority". When returning the run priority to
"Automatic", the run priority remains active at the current motor until the next
changeover by time.
8.4.5 Delay times
You can set a "Switch-on delay", "Switch-off delay", "On time minimum" and "Off
time minimum" for motors.
