ELSNER 70671 Intra-Sewi KNX L-Pr and TH-L-Pr Built-in Type Brightness and Presence Detectors, white

Intra-Sewi KNX L-Pr and TH-L-Pr Built-in Type Brightness and Presence Detectors, white 

• Presence detector/movement detector
• Mixed light measurement (daylight and artificial light)
• Constant light control for optimum use of daylight
• Awarded design with glass surface
• For ceiling installation
• Also as a combination sensor with room thermostat

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).

The Sensor Intra-Sewi KNX TH-L-Pr can output a warning to the bus as soon as the comfort field, as per DIN 1946, is left. Actuating variable comparators can compare and output variables that were received via communication objects.

All measurement values can be used for the control of limit-dependent switching outputs. States can be linked via AND logic gates and OR logic gates.
