Neo-TTHC-x KNX-Sensor used for measuring and controlling indoor air parameters Applications: Detection and control of room temperature and humidity Decentralized control for steady KNX-valves or thermal actuators Decentralized ventilation control depending on humidity Detecting of component temperature and temperature control ( Terminal for external PT1000 ) to prevent condensation and structural damage Evaluation of external switches and push buttons for switching functions Functions: PT1000 not included! Air temperature ( sensor in the housing ) also weighted with external temperature Humidity ( sensor in the housing ) Calculated values absolute humidity, dew point temperature and energy content ( enthalpy ) Additional floor, ceiling or component temperature ( Terminal for external PT1000 ) 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 Four binary inputs / outputs ( floating ) Four logic blocks for the logical link between internal and external signals.
