SK30-TC-CO2-PB 
KNX-Sensor used for measuring and controlling indoor air parameters

Applications:
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:
Air temperature ( sensor in the housing ) also weighted with external temperature
CO2 level ( sensor in the housing )
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 CO2 level
Fan control by CO2 limits and external inputs
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.
