Error messages remain displayed (and Status blinks) even after the error has disappeared; they
have to be deleted in the status menu via the command CLEAR.
You can only enter the status menu if there has been an error. Then, ENTER is displayed instead
of OK or CETOFF in Status.
OK appears under Status if the monitoring functions are activated and the system is running
well. If anything special happens, Status blinks regardless of the display position.
If one of the two control outputs is set to "STAT N" or "STAT I" and the function control is activated,
then if any of the errors "sensor open circuit, sensor short-circuit or circulation error" occur, the control
output is switched over. Subsequently an auxiliary relay can be used to forward this error message to
a signalling device. Upon collector excess temperature switch-off CETOFF, the control output does
not switchover.
