PUMP SET-UP
• Depressing shortly the button allows to display
the current set-up (operation mode)
• Depressing the button for more than 2 sec. gives

By default, the pump is set to the
"Porportional Pressure" mode / Curve 3 (See
symbols in bold in the table).
Available Operation Modes
Once the set-up is completed, the pump can
be locked to prevent any accidental change.
Press the button for more than 10 secondes
and all the LED will light (except the red one)
and blink for 1 second to indicate that the
lock is on. Proceed the same way to unlock.
Proportional pressure:
Default mode, applicable to most heating systems.
Pressure increases and decreases according to the
heat demands. Three preset curves are available,
from the lowest to the highest. The AutoAdapt curve
allows the pump to operate with the best efficiency
for the type of system. This is the preferred mode for
two-pipe systems, with thermostatic valves and long
piping (high pressure drop).
Constant pressure:
Pressure is kept constant whether there is a heat de-
mand or not. This is the typical mode for floor-heat-
ing systems or one-pipe systems with low pressure
drop.
Constant curve:
The circulation pump works according to a constant
curve, which is the standard operation for a pump.
The pump will then run following the max curve
when demand is high, e.g. in the case of DHW prior-
ity, and according to the min curve when demand is
low (night mode).
