When an error occurs, press the key (6) to display
the error message. The message on the display descri-
bes the cause of the error.
If an error occurs, an alarm may also activate a suitably

The difference between the setpoint and the current
temperature is monitored. If this difference persists for
longer than the time set here, the system generates an
error.
N°
6740 CH flow 1 temperature alarm
