3.1 Application

Temperature control for e.g.: extraction systems, warm-air heaters, air curtain installa-
tions, liquid-cooling, chillers.
Controlled output (0 - 10 V) e.g. for activating a speed controller for fans.
Fans with integrated controller and input 0 - 10 V can be activated directly.

3.2 Function

The measured actual value at the sensor is compared with the adjusted target value.
Output voltage and thus fan speed is controlled automatically depending on the adjusted
parameters.
Alternatively the device can be operated as temperature sensor. Output 0 - 10 V in this
mode proportional to the adjusted measuring range (max. -50...150 °C).

3.3 Storage

The device must be stored in its original packaging in a dry and weather-proof room.
•
• Avoid exposure to extreme heat and cold.
