FLOW
LIMIT
The FLOW
LIMIT
function can be combined with the following
control modes:
• Prop. pressure
• Con. diff. press.
• Con. diff. temp.
• Const. temp.
• Const. curve.
A flow-limiting function ensures that the flow never exceeds the
entered FLOW
LIMIT
value.
The setting range for FLOW
LIMIT
is 25 to 90 % of the Q
max
of the
pump.
The factory setting of the FLOW
LIMIT
is the flow where the
AUTO
ADAPT
factory setting meets the maximum curve. See fig.
Factory setting
See section
.
14.7 Automatic Night Setback
Once you have enabled automatic night setback, 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.
Factory setting
See section

14.8 Analog inputs
Available inputs depending on the functional module fitted in the
pump:
* See section
22. Identifying the functional module
.
Set the analog input for a feedback sensor via the "Assisted
pump setup" menu. See section
.
If you want to set an analog input for other purposes, you can do
this manually.
You can set the analog inputs via the "Setup, analog input" menu.
See section
.
If you perform the manual setting via Grundfos GO, you need to
enter the menu for the analog input under the "Settings" menu.
Function
The analog inputs can be set to these functions:
• Not active
• Feedback sensor
Sensor used for the selected control mode.
• Ext. setpoint infl.
