6. Cabling
6.1 General Information
• All low voltage cables should be laid along the shortest route.
• Ensure that low voltage and high voltage cables are separated
using metal planking on cable trays.
• Only shielded cables should be used as low voltage and bus
cables.
• Lay all BUS cables in a linear pattern. Star-shaped wiring is not
permitted (Figure on left).
• The KaController is connected via a bus connection to the
respective Venkon and must be connected to the Venkon's PCB.
Incorrect:
Star-shaped cabling of bus cables
All BUS cables are shielded, paired cables, for instance CAT5
(AWG23), however must be at least of the same value.
When laying bus cables, avoid the formation star points, for
instance in the junction box. Instead loop the cables through
the units (Venkons).

Programming Key
After the parameters have been set, setup can be simply copied to
other Venkon circuit boards with the aid of the programming key.
Please follow the following steps to copy setup:
1. Disconnect the previously programmed Venkon KaControl circuit
board.
Read parameters
2. Set the DIP switch of the programming key to Read mode
(DIP1 =OFF, DIP20 =OFF). The DIP switches are located
underneath the cover!
3. Plug the key into the 8-pin plug labelled IR on the Venkon circuit
board using the adapter cable.
4. Press the button on the programming key. If the copy is
successful, the red LED will light up followed by the green LED.
Loading parameters
5. Remove the programming key and set the internal DIP switches
of the programming key to Write mode (DIP1=OFF, DIP2=ON).
6. Repeat steps 3 and 4 to write the parameters to the Venkon
circuit board.
Important note:
The new Venkon circuit board should also be disconnected before
writing the parameters.
The programming key is not supplied as standard with the unit
and can be ordered from Kampmann Customer Service as a
non-standard accessory.
The software versions of the control circuit boards must be
identical when reading and writing the parameter sets (see
parameter P000).
It is not possible to read parameters from a control board using
software version "P000=33" for instance and then write the
parameters to a control board using software version "P000=37".

12. Functional Testing of Connected Assemblies
The KaController provides the option of checking the operation of
the connected external units independently of the software
application.
The function of individual assemblies, such as the fan, can be
directly enabled and checked using inputs on the KaController.
The functional test of the connected assemblies is called up and
implemented by the following operating steps:
1. Switch off the Venkon by:
• Pressing the ON/OFF key or
• Pressing the navigator for a minimum of 5 seconds or
• Turning the navigator to the left until OFF appears
2. Call up the Parameter menu by pressing the navigator for a
minimum of 10 seconds. The display shows "Para" and then "CODE"
with the value 000 in sequence.
3. Select the password (Code) 77 by turning the navigator and
confirm by pressing the navigator.
4. "L01" is shown on the display and the function test of the
connected assemblies can start.
Important note:
The individual test steps are called up by pressing the navigator.
The default view with "OFF" on-screen display is shown once the
test has been completed (L15).

* The control automatically detects the requisite sensors at the analogue inputs B1-B3 via the DIP
switch settings. If sensors are defective or not connected, this is shown by the respective display
(L01-L03) flashing.
** Outputs No4-No7 can only be tested when using the standard valve PCB.
Hardware-related locks should be observed during the functional test (refer to the respective
wiring diagram!)

13.2 Calling Up the KaController Parameter Menu
The following steps are needed to set the parameters:
1. Switch off the Venkon by:
• Pressing the ON/OFF key
or
• Pressing the navigator for a minimum of 5 seconds
or
• Turning the navigator to the left until OFF appears
2. Call up the Parameter menu by pressing the navigator for a
minimum of 10 seconds. The display shows "Para" and then "CODE"
with the value 000 in sequence.
3. Select the password (Code) 11 by turning the navigator and
confirm by pressing the navigator. You are now in the
KaController's Parameter menu.
4. Parameters can now be set using the navigator.
Setting parameters:
• Select the parameter by turning the navigator
• Call up Edit mode by pressing the navigator
• Enter the required value by turning the navigator
• Save the new value by pressing the navigator
There are 3 ways to exit the Service menu and call up the Standard
view:
