N° 70695 Sewi KNX L brightness sensor, jet black.

The Sewi KNX sensors record various indoor data depending on the model. The measurement values can be used each for the control of limit-depending switching outputs. States can be linked via AND logic gates and OR logic gates. Multi-function modules change input data as required by means of calculations, querying a condition or converting the data point type.

Some models offer a mixed value calculation and a variable comparator that compares and outputs values received by the communication objects.
All CO2 and humidity sensors have an integrated PI controller to control a ventilation system. All temperature sensors have a PI controller for a heating/cooling system.
