- Comply with country-specific standards, directives, specifications, and provisions for electrical installation.
- Switch off the voltage to the system during installation.
- The device may only be operated as a fixed-site installation, when assembled and after the conclusion of all installation and operational start-up tasks and only in the surroundings designated for it.
- Improper use, modifications to the device, or failure to observe this manual will void any warranty and guarantee claims.
Description
Indicator Light Green/Yellow/Red
The LED area of the Cala KNX IL The LED light signal can illuminate or flash in the colors green, yellow, or red. This allows states to be visualized for the KNX bus system. E.g. threshold value violations, room occupancy, or other status messages can be linked to Cala KNX IL, and the displayed color changes if these threshold values are exceeded/undercut. States can be linked via AND logic gates and OR logic gates. An integrated actuating variable comparator can compare and issue values that have been received via communication objects. With the Cala KNX IL CO2 model, the measured value of the integrated CO2 sensor can control the color of the illuminated area.
Via the bus, Cala KNX IL CO2 can receive an external CO2 value and process it with its own data to form an overall value (mixed value, e.g. room average). The CO2-measured value can be used for the control of
limit-dependent switch outputs. A PI controller regulates the ventilation according to CO2 concentration.
Scope of delivery
- 55 mm insert with LED illuminated area
- Supporting ring
- KNX plug-in terminal
Accessories required
- The frame (for insert 55 x 55 mm), is compatible with the switch scheme used in the building
- The socket according to DIN EN IEC 60670-1 / DIN 49073
- For Cala KNX IL CO2 use a windproof socket
Installation
The device is installed in a socket. Fig. 2
Note the installation provisions for SELV! The socket used must not contain any 230 V wiring! The metal supporting ring of the socket used must be isolated from
other metal parts (supporting rings), which could also touch 230 V cables, also via multiple touching metal parts! Select an installation location for Cala KNX IL CO2 where the measurement is distorted as little as possible by external influences. Drafts from windows or doors are a possible source of interference. Permanently measured value deviations can be corrected in the ETS (Offset).

Sensor assembly
First, install the box with the supply connection. For the version Cala KNX IL CO2 with integrated sensor, also, seal the supply connection ducts in order to prevent drafts. Then screw the support ring to the
socket and place the switch program frame. Connect the bus cable +/ to the KNX plug terminal and insert it into the slot intended for it (Fig. 4, No. 4). Insert the housing firmly onto the support ring using the clamps so that the sensor and frame are fixed together.
Maintenance
Fingerprints on the glass panel are removed with a cloth moistened with water or a microfiber cloth. Do not use an abrasive cleaning agent or an aggressive cleansing agent.
Disposal
After use, the device must be disposed of in accordance with the legal regulations. Do not dispose of it with household waste!
