  DESCRIPTION

(replaces 70662 Intra-Sewi KNX TH-Pr)

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).

• Brightness measurement with brightness control
• Motion detection
• 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
•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 two-stage) 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
