SK10-THC-CO2-RPFF / SK10-THC-CO2-RPFF-MMF The room pendulum sensors TH-CO2-RPFF and TH-CO2-RPFF-MMF are sensors for recording the air parameters temperature, moisture and CO2 content in high interiors. The Sensor TH-CO2-RPF-MMF with a metal-sinter-filter can also be used under impending condensation conditions. Both sensors are used together with the KNX coupling modules SK10-THC or SK07-THC. Applications: Room pendulum sensor for hanging from the ceiling Detection and control of room temperature Detection of CO2 level Decentralized control for steady KNX-valves or thermal actuators Decentralized ventilation control depending on air quality Evaluation of external switches and push buttons for switching functions Functions: Control functions for heating and cooling applications ( can also be combined ) Setpoint temperatures for Comfort, Standby, Economy and Protection, selectable via KNX HVAC objects Storage of minimum- and maximum-temperature Heat- and frost-alarm Limits for temperature and humidity Fan control by humidity limits and external inputs Controller output 0…100% or programmable PWM for thermal actuators Valve rinse function Second temperature controller as auxiliary controller Four logic blocks for the logical link between internal and external signals: 10 associated logic inputs / outputs Heat- and cooling-request as additionally available signals Functions "AND, OR, NOT, XOR" for binary logic Functions "+ - *" for 8-bit values Function "=" for conditional forwarding of events Technical Data: Measurement Temperature Relative Humidity CO2 level Calculated Values Absolute Humidity Dewpoint Temperature Enthalpie Control Integrated Operating voltage 3.3 VDC Power consumption 50mW Ø / 100mW peak Connection 4-Wires GND / VCC / SCL / SDA [ w (white) / y (yellow) / br (brown) / gn (green) ] Ambient temperature Storage -25 .. +85°C Operation -10 .. +60°C Ambient moisture 0% .. 100% not condensing Measurement range temperature -25 .. +80°C Resolution 0,02°C Accuracy ± 0,4°C (5..60°C), otherwise ± 0,8°C Measurement range moisture 0 .. 100% r.H.
