KNX-Sensor used for measuring and controlling indoor air parameters
Functions:
- Air temperature ( sensor in housing ) also weighted with external temperature
- Relative humidity ( sensor in 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 objects
- Storage of minimum- and maximum-temperature
- Heat- and frost-alarm
- Limits for temperature and humidity
- Fan control by humidity 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 contacts.
- Four logic blocks for the logical link between internal and external signals.
