KNX-Sensor used for measuring and controlling indoor air parameters

Applications:
To be added here!!

Functions:
Air temperature ( sensor in housing ) also weighted with external temperature
Relative humidity ( sensor in housing )
Calculated values absolute humidity, dew point temperature and energy content ( enthalpy )
External PT1000 connector ( PT1000 not included )
Control functions for heating and cooling applications ( can be combined )
Setpoint temperatures for Comfort, Standby, Economy and Protection, selectable via KNX HVAC objects
Setpoint change via objects
Storage of minimum- and maximum-temperature
Heat- and frost-alarm
Limits for temperature and humidity
Fan control by humidity limits and external inputs
Detecting of dew point temperature and alarm / regulation at risk of condensation
Adaptation for setpoint and maximum temperatures
Controller output 0…100% or programmable PWM for thermal actuators
Valve rinse function
Second temperature controller as auxiliary controller Two binary contacts.
Four logic blocks for the logical link between internal and external signals.
