ELSNER 70682 Intra-Sewi KNX L-Pr and TH-L-Pr

The Sensor Intra-Sewi KNX L-Pr for the KNX building bus system captures brightness and the presence of persons in rooms.

The Sensor Intra-Sewi KNX TH-L-Pr additionally measures the temperature and the air humidity and calculates the dew-point. Via the bus, the indoor sensor can receive external values of temperature and humidity and process them further with its own data to a total value (mixed value, e.g. room average). Integrated PI-controllers control ventilation (humidification/dehumidification according to humidity) and heating/cooling (according to temperature).
