Product Description
The KNX-Sensor SK07-TTHC-4B is used for measuring and controlling indoor air parameters.
External Sensors not included!
(the compatible sensors are listed in accessories tab below).
Features
- Air temperature ( external connection, PT1000 )
- Air temperature and humidity ( external connection, SHT71 )
- Calculated values absolute humidity, dew point temperature and energy content ( enthalpy )
- Primary temperature input also weighted with additional mixing temperature
- 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 objects
- Storage of minimum and maximum temperature
- Heat and frost alarm
- Limits for temperature, humidity
- Fan control via humidity limits and external inputs
- Detecting of dew point temperature with alarm / regulation at risk of condensation
- Adaptation for setpoint and limits temperatures
- Controller output 0..100% or programmable PWM for thermal actuators
- Valve rinse function
- Second temperature controller as auxiliary controller
Four binary inputs / outputs ( floating )
- 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 )
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
- Decentralized control for steady KNX-valves or thermal actuators
- Decentralized ventilation control depending on humidity and air quality
- Detecting of component temperature and temperature control to prevent condensation and structural damage
- Evaluation of external switches and push buttons for switching functions
