The road sensor detects the conditions “dry”, “damp” and “wet” above this limit (factory setting 1,5 °C).
Below this limit, there are, in addition, the conditions of “freezing wet” and “critical“ (Figure 21).
For other device settings see chapter 10.2.4

11.3 Examples for the Creation of Addresses
If, for example, a road sensor IRS31Pro-UMB is to be addressed with the device ID 1, this is achieved as
follows:
Class ID for the road sensor IRS31Pro-UMB is 9 = 9h
Device ID is 1= 1h
Placing the class and device ID’s together gives the following address 9001h = 36865d.
Activating compatibility mode changes the class ID to 1.
Class ID for the road sensor IRS31Pro-UMB is 1 = 1h
Device ID is 1= 1h
Placing the class and device ID’s together gives the following address 1001h = 4097d.
11.4 Firmware-Update
With an IRS31Pro-UMB in the compatibility mode it is very slightly possible that mistakenly an IRS31-
UMB firmware is programmed into the sensor. The adjustment data of the sensor thereby becomes
useless, and the sensor delivers no longer correct measuring values. The sensor can be repaired only by
a new calibration at the manufacturing plant.
Important Note: Before implementing any update, please check the name of Sensor.
To do this, load the current configuration via ‘Load profile from Sensor’. The current name of the sensor is
shown under ‘Name’ on the ‘Info’ page.
