N° 70681 Intra-Sewi KNX TH-L-Pr Presence, Brightness and Ambient Climate Sensor, white RAL 9010The 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.TECHNICAL DATAGeneral:HousingPlastic, glassColour• similar to signal white RAL 9003 (Intra-Sewi KNX L-Pr)• similar to pure white RAL 9010 (Intra-Sewi KNX TH-L-Pr)• similar to jet black RAL 9005Assemblybuilt-in, in false ceiling or connector socketDimensions Ø x height above wallapprox. 80 mm x approx. 5 mmheight in wall (installation) approx. 31 mm (incl. clamps)Degree of protectionIP 30Weightapprox. 50 gAmbient temperature-20… 60°CAmbient humidity5...95% RH, non-condensingStorage temperature-30… 70°CKNX bus:KNX mediumTP1-256Configuration modeS-ModeGroup addressesmax. 254Assignmentsmax. 254Communication objects• Intra-Sewi KNX TH-L-Pr: 252• Intra-Sewi KNX L-Pr: 122Nominal voltage KNX30 V DC SELVPower consumption KNXmax. 10 mAConnectionKNX plug terminalsDuration after bus voltage restoration until data is receivedapprox. 5 secondsSensors:Brightness sensor:Measurement range0 lux … 2,000 lux (higher values can be measured and output)Resolution1 lux at 0…2,000 luxPresence sensor:Coverage angleapprox. 94° × 82° (see also Coverage area of the presence detector)Rangeapprox. 5 mTemperature sensor (only Intra-Sewi KNX TH-L-Pr):Measurement range-20°C … 60°CResolution0.1°CHumidity sensor (only Intra-Sewi KNX TH-L-Pr):Measurement range0% rH … 100% rHResolution0.1% rH
