Product Description
The KNX-Sensor SK30-THC-CO2-R is used for measuring and controlling indoor air parameters.
Features
- Air temperature ( sensor in the housing ) also weighted with external temperature
- Humidity ( sensor in the housing )
- CO2 level ( sensor in the housing )
- Calculated values absolute humidity, dew point temperature and energy content ( enthalpy )
- 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 rotary controller and/or objects
- Storage of minimum- and maximum-temperature
- Heat- and frost-alarm
- Limits for temperature, humidity and CO2 level
- Fan control by humidity, CO2 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 )
Rotary controller
- Light control as switch / button with short, long, double and both function
- Dimmer
- Blind and shutter control
- Programmable Encoder
- Temperature adjustment
- The binary inputs can be configured as outputs ( LED / Beeper )
- Rotary controller to change the operational state ( comfort / standby ) and increase / decrease the setpoint temperature in several steps
The current state of the temperature controller can be indicated by LED’s
- Heating or cooling
- Slow pulsing if controller is active
- Pulse depth represents deviation between actual- and setpoint-temperature
- Display for comfort / standby / night mode configurable
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
Applications
- Detection and control of room temperature and humidity
- Detection of CO2 level
- Decentralized control for steady KNX-valves or thermal actuators
- Decentralized ventilation control depending on humidity and air quality
- Evaluation of external switches and push buttons for switching functions
