Sensor for CO2, Temperature, Humidity

The promotion runs until 05.06.2018 in the Elsner Elektronik online shop. A maximum of 1 promotional item can be ordered per customer.

Replacement for 70234-70237

The Sensor KNX AQS/TH-UP gl measures CO2 concentration, temperature and humidity and calculates the dew point. The sensor can receive external measured values via the bus and process them with the own data to overall values (mixed values, e. g. room average.

The KNX AQS/TH-UP gl provides switching outputs with adjustable threshold values. The switching outputs and further communication objects can be linked by AND and OR logic gates. Additionally, an integrated actuating variable comparator can compare and output values that are received via communication objects.

Integrated PI controllers allows for control of a ventilation (depending on CO2 concentration and air humidity) and a heating/cooling system (depending on temperature).

The KNX AQS/TH-UP gl can emit a warning to the bus as soon as the area of optimum comfort (according to DIN 1946) is left.

  • Measurement of CO2 concentration of the air, of temperature and air humidity (absolute and relative), calculation of the dew point
  • Mixed values from own measured values and external values (proportions can be set in percentage)
  • PI controller for heating (one or two step) and cooling (one or two step) depending on temperature. Control according to separate target values or basic target temperature
  • PI controller for ventilation depending on humidity and CO2 concentration: dehumidification/humidification (one step) or dehumidification (one or two step)
  • Threshold values can be adjusted per parameter or via communication objects: 3 × temperature, 2 × humidity, 4 × CO2
  • 4 AND and 4 OR logic gates with each 4 inputs. Every switching incident as well as 8 logic inputs in the form of communication objects, may be used as inputs for the logic gates. The output of each gate may optionally be configured as 1 bit or 2 x 8 bits
  • 2 actuating variable comparators for output of minimum, maximum or average values. Each with 5 inputs (for values received via communication objects)
  • Configuration is made using the KNX software ETS 5
