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 the tem-
perature of the ambient air. The physical parameters of mixing ratio, absolute humidity,
dew point and enthalpy are also calculated from these values. The 0-10 V output value
for the temperature is output at terminal 3, the 0-10 V output value for all other parame-
ters is output at terminal 2.
The respective output parameters can be selected and scaled (see wiring diagram) via
the DIP switch.
The 2 sensors AFS 0-10 V are designed for absolute humidity difference control in com-
bination with a control unit EUR EC / FU-C or FU-CS.
Application is possible indoors and outdoors. Do not expose the sensors to direct
sunlight.
Any use other than the intended use is prohibited!
