8.1 Factory setting
The control is factory preset.
The factory settings can be restored by Wilo cus-
tomer service.
8.2 Checking the speed adjustment
The motor speed is adjusted in the factory. To
check the speed adjustment, start the motor manu-
ally. Once the motor has started, record the speed
with a portable rev counter and compare it to the
speed on the display. If the two values match, no
correction is necessary.
If the difference is large, readjustment is necessary.
Proceed as follows. Set the motor to a constant,
known speed. Enter and confirm this value in
menu 1.2.1.1. Go to the next menu item. In
menu 1.2.1.2, change the setting to "Start" and
confirm. After the adjustment, "Finished" appears
on the display. The speed adjustment is complete
and saved. The motor can be stopped by pressing
the "stop" button (Fig. 2, item 14).
