13.5 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 +18 to +27 °F (-8 to -3 °C) within approx. two hours.
The temperature drop must be at least 0.18 °F/min (0.1 °C/min).
Changeover to normal duty takes place without a time lag when
the temperature has increased by approx. +18 °F (-8 °C).
Automatic Night Setback cannot be enabled
