the description for this item.
The structure of the main menus Humidity (HuMi) and Tem-
perature (tEMP) is identical. Here you can configure the
switching outputs or the analogue outputs (if applicable).
The basic device settings can be changed. General settings can
be configured under Basic Settings Advanced Functions (b.EF).
These settings should be configured first, as they affect the

This explanation of the operation applies to the sensor ver-
sions without display.

5.2.1 Switching outputs

The sensor has one switching output assigned to humidity.
The threshold is preset to 80 %. The switching function is a NC
contact. This switching output can be configured ex works or
via the digital interface.
For the functionality please refer to chapter Switching out-
puts.

5.2.2 Analogue outputs

The sensor version features up to two 4-20 mA analogue out-
puts. The analogue outputs are available for the relative hu-
midity and temperature. The scale is preset and can be factory
configured or via the digital interface. By default the analogue
output shows the relative humidity as 0 % to 100 %. The ana-
logue output shows the temperature from -20 °C to 120 °C.
