Sewi KNX AQS/TH-D - KNX Sensor measuring CO2, Temperature, Humidity, Pressure, white

Description

• Threshold values can be adjusted per parameter or via communication objects
• 8 AND and 8 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 from each gate can be configured optionally as 1-bit or 2 x 8-bit
• 8 multi-functional modules (computers) for changing the input data by calculations, by querying a condition or by converting the data point type 
• Configuration is carried out with the KNX software ETS 
• For devices with mixed value calculation the share of internal measurement value and external value can be set as a percentage On devices with PI control for heating/cooling it can be heated and cooled in one or two stages. Regulation is done according to separate setpoints or basic setpoint temperature  
• On devices with PI control for ventilation it can be ventilated/aerated in one stage or ventilated in one/two stages 
• On devices with variable comparator minimum, maximum or average values can be output. For each comparator 5 inputs are available for values received via communication objects
• On devices with summer compensation for cooling a characteristic curve matches the set temperature in the room to the external temperature and sets the minimum and maximum target temperature values
• Measuring the CO2 concentration of the air, the temperature and air humidity (relative, absolute), each with mixed value calculation
• Bus warning with regard to whether the values for temperature and air humidity are within the comfort field (DIN 1946). Dewpoint calculation
• Air pressure measurement. Output of the value as normal pressure and optionally as barometric pressure
• PI control for heating/cooling according to temperature
• PI control for ventilation according to humidity and CO2 concentration
• 4 variable comparator
• Summer compensation for cooling systems
