Installation and operating instructions
Description of controls
Basic settings
The KaControl version provides the option of controlling
KaDeck unit by means of a control unit supplied separately or
on-site building management technology.
A number of different settings and configurations are possible
using the DIP switches on the PCB and parameters that can be
set by the control unit.
This manual provides only a brief overview. Please refer to
the separate KaControl instruction manual for further setting
options.
The KaControl system offers the possibility of grouping,
although an extension board (CANbus), available as an
accessory, then needs to be provided.

Changing to ON means that the cassette is no
longer controlled by the KaControl unit, rather
by means of a 0-10V signal on the AI2/GND
and AI3/GND input (see separate KaControl
instructions).

Changing to ON means that the cassette
is no longer controlled by the KaControl
unit, rather by means of an external 0-100
kOhm potentiometer signal on the AI2/GND
and AI3/GND input (see separate KaControl
instructions).

If the function is activated, the operating mode
of the cassette can be changed by an external
potential-free contact. The contact acts on
input DI2/GND.

The cassette is either configured as a 2-pipe
heating or cooling unit or as a 4-pipe heating
and cooling unit depending on the setting.

cassette
OFF
OFF
The cassettes have an air intake temperature
sensor for room temperature setting. Set the
DIP switch to ON if the temperature is to be
detected at the control unit.
If several cassettes are integrated in a group,
the DIP switch has to be set to ON.

Potentiometer
The maximum speed can be set using the potentiometer. The maximum speed and thus also the air
volume and sound pressure level can be reduced, for example if a maximum sound level is not to
be exceeded. The maximum cooling and/or heating output is correspondingly reduced by this.
