Cala KNX IL (CO2) by Elsner | new deep black colour variant

When choosing switch components, appearance matters just as much as function. With the new Deep Black (RAL 9005) colour variant, Elsner Elektronik's Cala KNX IL and Cala KNX IL CO2 now integrate seamlessly into projects with dark switch ranges.

Cala KNX IL visualises status messages and warnings via a coloured LED indicator. Cala KNX IL CO2 extends this with an integrated CO2 sensor and automatic ventilation control. Both variants fit standard 55 mm switch ranges and Swiss 60 mm installation systems, offering flexible on-site visualisation of KNX system states.

Room occupancy, window status, air quality, or technical faults: Cala KNX IL and Cala KNX IL CO2 provide intuitive, at-a-glance status directly in the room, with no need for apps or additional displays. The new colour variant now adds a further degree of design freedom to high-end KNX projects.

Typical applications

Residential buildings – window contact, fault and alarm status visualisation
Offices & meeting rooms – room occupancy and air quality display
Schools & nurseries – CO2 indicator light for demand-controlled ventilation
Event venues – combined CO2 value from multiple sensors

The Cala series: the all-round solution for standard frames

Cala KNX IL and Cala KNX IL CO2 are part of the wider Cala range, designed to fit the most common wall-mounted frame systems on the market, with no need for proprietary hardware.

The glass finish, available in Deep Black (Tiefschwarz) and Pure White (Reinweiß), gives every device in the series a shared aesthetic — from the simplest push-button to the touch display — allowing installers to build coherent systems throughout a building. Alongside Cala KNX IL and IL CO2, the range also includes:

Cala KNX M-T – single, double, or quadruple glass push-button with integrated temperature sensor, replacing traditional light switches
Cala KNX T 101 / T 201-202 Sunblind – room temperature controllers with illuminated digit display and touch buttons for heating control and, on the 201/202 models, blind and sun protection control
Cala KNX MultiTouch T – push-button with printed icons for light, temperature, scenes, or sun protection, designed for environments with multiple users (e.g. hotels)
Cala Touch KNX – the series' flagship touch panel, for integrated control of light, sun protection, and room temperature, also available in an AQS/TH variant with CO2 and humidity sensors

This modularity makes the Cala series an all-round solution for KNX projects of any size, from single rooms to complex buildings, always maintaining design and functional consistency.
