Pump start
Before starting the pump, make sure that the system is filled with liquid (heating medium),
the system has been properly vented and the pressure at the pump inlet has reached the
minimum inlet pressure as required.
Venting
Before first start-up and before each heating season, the pump must be de-aerated. The
above can be carried out by starting the pump in the top gear 3 and unscrewing the vent
unions. If no air escapes from the resulting hole, and only water flows out into the hole,
screw the cap with the seal on it.

proportional
pressure characteristics
-
The AUTO function controls the pump efficiency automatically in
theb pecified range.
- It adjusts the pump efficiency depending on the system size;
- It adjusts the pump efficiency according to the load change for
a certain eriod of time;
- In the AUTO mode, the pump is set for the proportional pressure
control mode.
PP: I / II / III
Curves of proportional
pressure
The operating point will move up and down along the
proportional pressure curve depending on the demand of the
system flow: when the flow demand decreases - the water pump
pressure drops; whereas when the energy demand increases - it
increases.
CP: I / II / III
Curves of constant
pressure
The operating point of the pump moves forward and backward
o the constant pressure curve according to the system demand.
The water pump pressure remains constant, it has no relation to
the flow demand.
S: I / II / III
(S III - factory
settings)
Curves of constant rotary
speed.
HS (1-3), the pump is set for the maximum curve in all operating
conditions.
If the pump is set in the HS3 mode, the pump will be vented
quickly.
No. Function Description Operation
1 Venting
Exhaust the air inside the pump
to ensure normal working (this
function does not vent the
heating system)
Press and hold the button for 5 seconds until
LED1+LED2+LED3 light up.
The pump will vent automatically for 5 minutes.
2 Manual restart Retart the pump manually
Press and hold the button for 8 seconds. until
LED1+LED2+LED3+LED4+LED5 light up and then
release.
The pump will start nad stop continuously for 5
minutes to unlock.
