A1 = Initial start-up:
The following queries are carried
out at initial start-up:
1.) Controller address: In case that
only one controller is connected,
address 1 can be used. If several
controllers (max. 4) should be
connected, each controller must
be assigned to an address of its
own (see point D8).
2.) Language: Selection: German,
English, French or Italian (see
point D8).
3.) Date and time: Setting of the
current date and time (see point
D9).
Master / Slave – Mode:
Via Dip-switch 1 – on/off (see wiring
diagram SS-950), a KWL-unit can be
defined as a Master- or Slave unit. It
is to be noted that in the network only
one Master-unit is defined. The
remaining KWL-units must be defi-
ned as Slave-units, which are then
subordinated to the Master automati-
cally.
Thus one or more KWL-units (max.
10, see wiring diagram SS-958) can
be operated via the control system.
B5-B14 = Auto / Manual – Mode:
The speed control of the KWL-unit is
carried out by an automatic or
manual power control. In the auto-
matic mode the speed control takes
place in dependence of the room
humidity,
the
CO
2
-concentration
and/or the weekly program. For this
accessory components like CO
2
-
sensor respectively humidity sensor
must the connected.
In the manual mode the speed con-
trol is carried out individually. By tur-
ning of the rotating encoder knob the
following levels can be selected:
Level 0-1-2-3-4-intake air-extract air.
If the CO
2
-concentration rises over
1600 ppm or the humidity value is
over 80 % relative humidity, an infor-
mation “humidity alarm” or “CO
2
-
alarm“ appears, i.e. the selected
speed step is insufficient.
C1 = Booster mode:
After activating the booster mode,
the KWL EC Pro operates in the pre-
set speed step. The remaining runti-
me in the booster mode is shown in
the display and can be deactivated at
any time. Over submenu D3 (boo-
ster), speed step and booster runti-
me (1 - 180 minutes) can be set indi-
vidually.
C2 = Whisper mode:
After activating the whisper mode,
the KWL EC Pro operates in the pre-
set speed step. The remaining runti-
me in the whisper mode is shown in
the display and can be deactivated at
any time. Over submenu D4 (whisper
mode), speed step and booster run-
time (1 - 180 minutes) can be set
individually.
C4 = Clock timer:
It is possible to select between 6
already preset weekly programs: WP
1, WP 2, WP 3, WP 4, WP 5, WP
OFF. Select and confirm the desired
WP in the submenu C4.1 (standard
weekly program) for this purpose. If
an individual weekly program is to be
created, this can be specified in the
submenu 4.2 (individual weekly pro-
gram) for each weekday.
C5 = Vacation program:
For example a firm vacation date can
be deposited over the menu vacation
program. For this time duration an
individual ventilation process can be
set. At the beginning of the vacation
it starts automatically and switches
off again independently. The result is
an ideal ventilation of your property
during this time.
C6 = Sensor values:
A humidity sensor is factory-installed
in the unit. The humidity values are
manually adjustable and are display-
ed in the graphic display of the con-
troller.
Furthermore, up to four CO
2
-sensors
(accessories:
KEL-CO
2
,
Ref.No.
9988) for detection of the CO
2
con-
centration in the indoor air can be
connected and displayed.
C7 = Settings:
Over the setup menu several para-
meters can be adjusted individually.
D1 = Humidity control:
The most important functions are
defined in the submenu D1.
If the humidity control is activated,
the ventilation control takes place as
a function of the relative humidity,
which is measured directly in the
extract air. Following individual set-
tings are possible:
Setpoint: Setting of relative humidity
for level 1.
Switching steps: Switching threshold
in next level run on time: If the set-
point is not reached within 2 hours, a
mandatory pause takes place from 0
to 24 hours, in order to prevent a
continuous running.
D6=Supply and extract air level:
The supply and extract air level can
be set individually.
D7 = Filter change:
The interval for changing the filter can
be set between 2 till 9 months. The
remaining period for a filter change
can be displayed by a query. With an
earlier filter change, the remaining
period must be reset.
