SK30-TTHC-PB 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: 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 front buttons and/or 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 inputs / outputs ( floating ) Two front buttons The current state of the temperature controller can be indicated by LED’s. Four logic blocks for the logical link between internal and external signals.
