ween 0 – 100 %.

An operating hours reset can only be
carried out in the factory.
E2 = Heat exchanger frost protec-
tion:
0 till 10° C
E3 = Min. fan speed
The minimum fan speed can be set
between level 0 and 1. If level 0 is
specified, the KWL-unit can be swit-
ched off. If level 1 is specified, level 0
cannot be activated, nor in the wee-
kly program.

The controller address can be chan-
ged later. It should be noted that the

All parameters can be reset to fac-
tory setting. If the settings in the wee-
kly program should not be reset, this
option can be set in advance.
E13 = Motor monitoring:
Speed monitoring: The motors are
speed monitored – if the speed in
level 1 falls below 1100 1/min, auto-
matically a speed increase follows to
level 2. If the speed is still below 1100
1/min after about 10 seconds, the
KWL-unit stops and the shutters clo-
se. This also occurs if the speed is
too low in level 2 - 4.
Current monitoring: The motor cur-
rents are monitored permanently – if
minimum or maximum value is rea-
ched, the KWL-unit stops and the
shutters close.
Voltage monitoring: The output volta-
ges at the board are monitored per-
manently - if minimum or maximum
value is reached, the KWL-unit stops
and the shutters close.
