Fibaro Thermostat read additional function status parameter values

Hi there

I would like to read the value of the “additional function status” parameter. It’s a read only parameter. In the zwave configuration page I cannot see a way to show the current value. I only seem to find it as an entry in the drop down menu for the node configuration, which shows me to set the parameter values but not simply display the current value.

Many thanks for your help.
