Instructions for installation and use
Check the pump setting by pressing the button once
(one constant pessure). The LEDs will brie y (2 sec.)
show the pump setting before changing back to show-
ing the power consumption.
See g. 3 - Pump setting view.
If the pump setting does not give the desired distribu-
tion of heat in
the rooms of the house, change the pump setting.
See g. 3 - Pump setting view.
Before starting the setting, make clear what the dis-
play should show for the new setting (see g. 3).
To change the pump setting, choose the setting you
want (see g. 3), press the button down for more than
2 seconds (less than 10) and the pump switches to
setting selection, the LEDs start ashing and display
the current setting. Then press the button until the
LEDs shows the desired setting. The LEDs ash and
when they stop the new setting is saved. The LEDs
return to show power cunstumption.
Please note that if the LEDs do not ash after 2 sec-
onds, possibly the pump setting is locked. To unlock,
press the button down for more than 10 seconds. LEDs
will ash and the pump is unlocked. To lock the pump,
repeat the procedure.
For more information, se enclosed Grundfos in-
structions.
Alarm status
In case the 1st LED is red the pump has detected one
or more alarms.
See g. 4 - Alarm status.
When there is no active alarm anymore the user inter-
face switches back to operation mode shortly and then
showing power consumption.
