12.5 Automatic Night Setback
Navigation
Home > Settings > Automatic Night Setback
Automatic Night Setback
To enable the function, select "Active" with
[OK].
Once Automatic Night Setback has been enabled, the pump
automatically changes between normal duty and night setback
(duty at low performance).
Changeover between normal duty and night setback depends on
the flow-pipe temperature.
The pump automatically changes over to night setback when the
built-in sensor registers a flow-pipe temperature drop of more
than 10 to 15 °C within approx. two hours. The temperature drop
must be at least 0.1 °C/min.
Changeover to normal duty takes place without a time lag when
the temperature has increased by approx. 10 °C.
Automatic Night Setback cannot be enabled
Note
when the pump is in constant-curve mode.

The pump incorporates two signal relays, terminals 1, 2 and 3, for
a potential-free alarm signal, ready signal and operating signal.
For further information, see section 4.5.1 Relay outputs.
Set the function of the signal relays, alarm signal (factory setting),
ready signal and operating signal, on the pump control panel.
The output, terminals 1, 2 and 3, is electrically separated from the
rest of the controller.
The signal relay is operated as follows:
Not active
•
The signal relay is deactivated.
Ready
•
The signal relay is active when the pump is running or has
been set to stop, but is ready to run.
