  • Page 4: Product Description

    The sensor can receive an external measured value via the bus and process it with the own data to an overall temperature (mixed value). The KNX T-AP provides four switching outputs with adjustable threshold values as well as additional AND and OR logic gates. The sensor has got a PI controller for heating and cooling.

    Elsner Elektronik does not assume any liability for changes in standards after publication of this instruction manual. Installation position The sensor is designed for surface mounting. When selecting an installation location, please ensure that the measurement results are affected as little as possible by external influences.

  • Page 7: Connection Of The Temperature Sensor

    Connection of the temperature sensor Remove the screwed on cover. Lead the KNX bus connection cable through the cable entry on the bottom of the casing and connect the bus +/- to the terminal provided for this purpose. Screw the cover back on. Notes on installation Do not open the temperature sensor if penetration of water (rain) is likely: Only a couple of drops could damage the electronic.
