The Sensors Mini-Sewi KNX T and Mini-Sewi KNX TH measures the ambient temperature. Mini-Sewi KNX TH additionally captures the air humidity and calculates the dew-point. Via the bus, the indoor sensors can receive external values of temperature or humidity and process them further with their own data to a total value (mixed value, e.g. room average).
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. In addition, an integrated actuating variable comparator can compare and output variables that were received via communication objects.
An integrated PI-controller controls a heating/cooling (according to temperature). Mini-Sewi KNX TH offers a second controller for ventilation (humidification/dehumidification according to humidity) and a warning can be output to the bus as soon as the comfort field, as per DIN 1946, is left.
