Alarm – OK
– Alarm
Current pump alarm state.
Go to page with digital input settings. For exam-
ple, you can set the time for jitter protection (De-
fault: 0 s).
Start up delay fdbk 0...36000 [s] Defines the period after a pump start without
feedback before a feedback alarm is triggered.
Jitter time is enabled exclusively if the feedback
is pending after this period.
Off by fdbk alarm – No

Determines, in the event of a feedback fault,
whether a pump command is still pending or
whether to switch off the command.
Outs tmp start -64...64 [°C] The pump starts when the outside air tempera-
ture drops below this value. Heat is thus avail-
able immediately for heating (passive frost pro-
tection) when switching on the plant.
The function is disabled when no outside air
temperature is configured or the sensor fails.
Min run time 0...36000 [s] Define the minimum runtime for the pump after a
start.
Feedback can only be used as alarm, when Contact function = NO (Normally
Open) and the element is set to ON.
