Brightness and Presence Detectors
KNX ceiling sensor in different variants with brightness sensor and presence detector. With light control. With logic gates
Highlights
-
-
Presence detector/movement detector
-
-
Mixed light measurement (daylight and artificial light)
-
-
Constant light control for optimum use of daylight
-
-
Compact surface-mounted housing
- - Also as a combination sensor with room thermostat
The Sensor Mini-Sewi KNX L-Pr for the KNX bus system captures the presence of persons even in the event of slight movements, such as sedentary activity in the office. Permanentbrightness monitoring means that the light can be switched off from an adjustable brightness value.
The Sensor Mini-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 Mini-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.
Models:
N° 70403 Mini-Sewi KNX TH-L-Pr Presence, Brightness and Ambient Climate Sensor
N° 70428 Mini-Sewi KNX L-Pr Presence Detector with Brightness Sensor
- Brightness measurement with brightness control
- Presence of persons is detected
- Threshold values can be adjusted per parameter or via communication objects
- 4 AND and 4 OR logic gates, each with 4 inputs. All switching events as well as 16 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output of each gate can be configured optionally as 1-bit or 2 x 8-bit
Configuration is made using the KNX software ETS.
Additional functions Mini-Sewi KNX TH-L-Pr:
- Measuring the temperature and air humidity (relative, absolute), each with mixed value calculation. The share of internal measurement value and external value can be set as a percentage
- Bus message, whether the values for temperature and air humidity are within the comfort field (DIN 1946). Dew point calculation
- PI-controller for heating (one or two-stage) and cooling (one or twostage) according to temperature. Regulation according to separate setpoints or basic setpoint temperature
- PI controller for humidity according to humidity: Ventilate/Air (one-stage) or Ventilate (one or two-stage)
- 2 actuation variable comparators to output minimum, maximum or average values. 5 inputs each for values received via communication objects
