E3 = Min. fan speed
The minimum fan speed can be set
between level 0 and 1. If level 0 is

ched off. If level 1 is specified, level 0
cannot be activated, nor in the wee-

E13 = Motor monitoring/
fault management:
Fan speed 1:
1. With a rotational speed error in LS
1 that lasts longer than 30 seconds,
the unit switches to LS 2.
2. If the error still exists after 1 minu-
te, the unit remains in LS 2.
If the error does not exist any more,
the unit switches again to LS 1.
Fan speed 2 - 4:
In these fan speeds no automatic
switching takes place on another fan
speed.
Note: Regardless of the error eva-
luation via the speed signal, the
motor has its own error manage-
ment, which shuts down on
blocking and tries cyclically a swit-
ching on.
