Description
Cala KNX IL CO2 CH is an LED light signal that indicates the air quality in the room. The CO2 concentration is measured by the integrated sensor and controls the colour of the light surface. The LED surface lights up or flashes in the colours green, yellow or red.
However, Cala KNX IL CO2 CH does not only make the carbon dioxide pollution visible. It also regulates the ventilation via KNX accordingly.
In some places it makes sense to use a CO2 room average for display and control. For this purpose, Cala KNX IL CO2 can calculate a mixed value from a CO2 value received via the bus and its own value.
The KNX application of the device offers further intelligent functions for the KNX system:
- The CO2 value controls switching outputs depending on the limit value.
- AND/OR logic gates link states.
- Values received via communication object are compared and output in the control value comparator.
Cala KNX IL CO2 CH can also visualise other states in the KNX bus system, e.g. limit value violations or status messages. The functionality then corresponds to that of the Cala KNX IL model.
Cala KNX IL CO2 CH is inserted into the 60 mm frame of a Swiss switch range and thus fits seamlessly into the interior design.
Models:
No. 71391 Cala KNX IL CO2 CH, pure white RAL 9010
No. 71393 Cala KNX IL CO2 CH, jet black RAL 9005

Functions
- Measuring the CO2-concentration in the air each time with mixed value
calculation. The share of internal measured value and external value can be
set as a percentage - Use of the CO2-concentration for the indicator light function
- Display (permanent or flashing) of one of the colours Green, Yellow or Red
- Threshold values can be adjusted per parameter or via communication
objects - PI controller for two-stage ventilation according to CO2-concentration
- 4 AND and 4 OR logic gates each with 4 inputs. All switching events as well
as 16 logic inputs (in the form of communications objects) can be used as
inputs for the logic gates. The output from each gate can be configured
optionally as 1-bit or 2 x 8-bit - 2 control variable comparators to output minimum, maximum or average
values. 5 inputs each for values received via communication objects - Indicator light for visualising states (e. g. limit value violations, room
occupation of status reports)
