8.2 Display
The display (1) is on when you have switched on
the power supply.
The display shows the actual pump power
consumption in watt (integer) or the actual flow
during operation.
If a fault is indicated, correct the fault and reset
the pump by switching the power supply off and
on.
If the pump impeller is rotated, for example
when filling the pump with water, sufficient
energy can be generated to light up the display
even if the power supply has been switched off.
Light field indicating high and low flow
• The light field blinks for low flow
– If the flow is lower than 1 gpm, the light
field alternately flashes between "0" and
"1" randomly.
• The light field shows HI for high flow
– If the flow is higher than 12 gpm, the light
field shows "HI" on user interface.
8.2.1 Light fields indicating the pump setting
The pump has optional performance settings
which you can select with the push-button. See

Heating systems are "slow" systems that cannot
be set to the optimum operation within minutes
or hours.
However, if the recommended pump setting in
some applications does not give the desired
distribution of heat in the rooms of the house,
you can change to an alternative pump setting.
