[EN] - Residual head of circulator
The boiler is equipped with a high efficiency
modulating circulator already hydraulically
and electrically connected, whose useful avail-
able performance is indicated in the graph.
The modulation is managed by the board
through the PUMP DUTY CYCLE - access
level INSTALLER.The circulator is factory set
with discharge head of 7 meters. The boiler is
equipped with an anti-blocking system which
starts up an operation cycle after every 24
hours of disuse in any operating status.
b
The "anti-locking" function
only activated when the boiler is
electrically powered.
a
It is strictly forbidden to operate the
circulator without water.
Where there is the need to use a different
curve, the desired level can be selected on
the circulator.
Variable speed circulator

ble only to the boiler circulator and not to the
circulators of any external devices connected

(e.g. booster circulator)) is only active in the
heating function. The circulator always oper-
ates at maximum speed when switching the
three-way to DHW. Through the PUMP DUTY
CYCLE parameter it is possible to choose
between:
1 - VARIABLE SPEED CIRCULATOR WITH
PROPORTIONAL MODE (41 <= PUMP
DUTY CYCLE <= 100): the boiler board
determines which flow rate curve to adopt
according to the instantaneous power deliv-
ered by the boiler.
2 - VARIABLE SPEED CIRCULATOR WITH
CONSTANT ∆T MODE (2 <= PUMP
is
DUTY CYCLE <= 40): the installer sets the
∆T value to be maintained between outlet
and return (e.g .:by entering a value = 10,
the circulator speed will change to achieve
a system flow rate with the aim of maintain-
ing the ∆T of 10°C upstream and down-
stream of the exchanger).
3 - CIRCULATOR IN MAXIMUM FIXED
SPEED MODE (PUMP DUTY CYCLE =
1): the circulator, when activated, always
operates at maximum speed. Used on
systems with high pressure drop where

it is necessary to make the most of the
boiler discharge head in order to ensure
sufficient circulation (system flow rate at
maximum speed less than 600 litres per
hour).
