Absolute Feuchte-Sensor – AFS 0-10 V
1.0 Important information
In order to ensure complete and effective operation and for your own safety, all of the
following instructions should be read carefully and observed. The relevant national
standards, safety regulations and instructions (e.g. DIN EN VDE 0100) as well as the
technical connection conditions of the energy supply company must be observed and
applied.
Keep the operating instructions close to the unit for easy reference. After the final assem-
bly, the document must be issued to the operator (tenant/owner).

applicable regulations and EC guidelines at its date of manufacture.
1.4 Receipt
The delivery contains the Absolute Humidity Sensor AFS 0-10 V
Please check delivery immediately on receipt for accuracy and damage. If damaged,
please notify the carrier immediately. In case of delayed notification, any possible claim
may be void.
1.5 Storage
When storing for a prolonged time, the following steps are to be taken to avoid damaging
influences:
Protection by dry, air-dustproof packing (plastic bags with drying agent and moisture
indicators). The storage place must be waterproof, vibration-free and free of temperature
variations. Damages due to improper transportation, storage or commissioning must be
verified and are not liable for warranty.
1.6 Area of application – Functions
The Absolute Humidity Sensor AFS 0-10 V measures the relative humidity and tempera-
ture of the ambient air. From this data, the sensor also calculates the physical variables of
mixing ratio, absolute humidity, dew point and enthalpy for the 0-10 V output value. The
0-10 V output value for the temperature is issued to terminal 3, and the 0-10 V output
value for all other variables is issued to terminal 2.
The respective output variables can be selected and scaled via the DIP switch (see
wiring diagram).
Unit can be used in internal and external areas. Do not expose to direct sunlight.
Information on setting the output size of the humidity measurement:
Three physical output options are available. In particular, in case of a differential control
with 2 sensors for drying internal areas, the following must be considered:
