The Sewi KNX TH-L-Pr sensor for the KNX bus system detects brightness and the presence of people in the room. It measures the temperature and humidity and calculates the dew point. The indoor sensor can receive external values of temperature and humidity via the bus and process them with its own data to create total values (mixed values, e.g. room average). All measured values can be used to control limit-dependent switching outputs. The states can be linked via AND logic gates and OR logic gates. Multifunctional modules change input data as required by calculations, querying a condition or converting the data point type. In addition, an integrated manipulated variable comparator can compare and output values received via communication objects. Integrated PI controllers control ventilation (according to humidity) and heating/cooling (according to temperature). The Sewi KNX TH-L-Pr can issue a warning to the bus as soon as the comfort zone according to DIN 1946 is left.
