The Mini-Sewi KNX TH-L-Pr sensor for the KNX building bus system detects brightness and the presence of people in the room. It also measures the temperature and humidity and uses this to calculate 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). Integrated PI controllers control ventilation (humidification/dehumidification based on humidity) and heating/cooling (based on temperature). The Mini-Sewi KNX TH-L-Pr sensor can issue a warning to the bus as soon as the comfort zone according to DIN 1946 is left. Control variable comparators can compare and output values received via communication objects. All measured values can be used to control limit-dependent switching outputs. The states can be linked using AND logic gates and OR logic gates.
