Operating status
The controller goes through some regulating situations where it is just waiting for the next
point of the regulation. To make these "why is nothing happening" situations visible, you
can see an operating status on the display. Push briefly (1s) the upper button. If there is a
status code, it will be shown on the display. The individual status codes have the following
meanings:
