Measuring humidity or temperature only
Operation of the XB3 does not require both current loops to be closed. When using the XB3 to measure either
humidity only or temperature only, close only the loop that is being used.
Using the ROTRONIC HW4 software, any unused output of the XB3 can be disabled.
