SK30-TC-CO2-PB
KNX Sensor Temperature Control CO2 Concentration 2 Front Buttons + 2 Binary Inputs / Outputs - white
Product code:
30512371
The KNX-Sensor SK30-TC-CO2-PB is used for measuring and controlling indoor air parameters
Description
- 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 - 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 )
- Front button 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 LEDs. - 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
- 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
