Why doesn't the HCC/S 2.x.x.1 show the status of the valve purge?

If the purge status is parametrized as default with "No, update only," the status is not shown, but the "hidden" status is updated.
If you want to see the status as soon as the purge is activated, the parameter "After a change" must be chosen.

Note: During a purge, the control value is not sent!
