Selected Setting view
You can switch from the performance view to the se-
lected settings view by pressing the push button. The
LEDs indicate the actual setting. The settings view
shows which mode controls the circulator. You cannot
change settings at this stage. After 2 seconds, the dis-
play switches back to performance view.
If LED 1 is green, it indicates operation or internal con-
trol.
If LED 1 is red, it indicates alarm or external control.
LED 2 and 3 indicate the different control modes and
LED 4 and 5 indicate the different curves.
Setting the control mode
Check the pump setting by pressing the button once
(one constant pessure). The LEDs will briefly (2 sec.)
show the pump setting before changing back to show-
ing the power consumption.
See fig. 5 - 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 fig. 5 - Pump setting view.
Before starting the setting, make clear what the dis-
play should show for the new setting (
see fig. 5
).
To change the pump setting, choose the setting you
want (see fig. 5), press the button down for more than
2 seconds (less than 10) and the pump switches to
setting selection, the LEDs start flashing and display
the current setting. Then press the button until the
LEDs shows the desired setting. The LEDs flash and
when they stop the new setting is saved. The LEDs
return to show power cunstumption.
Please note
that if the LEDs do not flash after 2 sec-
onds, possibly the pump setting is locked. To unlock,
press the button down for more than 10 seconds. LEDs
will flash and the pump is unlocked. To lock the pump,
repeat the procedure.

structions.
