Operating status
Operating status of the controller can be called forth in the display.
Push briefly (1s) the upper button. If there is a status code, it will be shown on the dis-
play. (Status codes have lower priority than alarm codes. In other words, you cannot
see a status code, if there is an active alarm).
The individual status codes have the following meanings:
EKC Status
(0 = regulation)
S10: The regulation stopped by the internal or external start/ stop
