Operating status
(Measurement)
The controller goes through some regulating situations where it is just waiting for the
next sequence of the regulation. To make these “why is nothing happening” situa-
tions visible, you can see an operating status on the display. Push the info button for
3 seconds to see status. If there is a status code, it will be shown on the display. The
individual status codes have the following meanings:

range. The regulation will continue with a registered average cut-in frequency. There are two registered values – one for day operation and one for
night operation.
