Circulation pump.
The units are supplied with circulating pumps
fitted with speed regulator.
These settings are suitable for most systems.
In fact, the pump is equipped with electronic
control to set advanced functions. For proper op-
eration one must select the most suitable type of
operation for the system and select a speed in the
available range, with a focus on energy savings.
Display of operation status. During normal
operation, the status LED (2 Fig. 4) is switched on
and green (flashing (FL) when it is in stand-by),
the four yellow LEDs (3 Fig. 4) indicate the pump
absorption according to the following table:

Selection of operating mode. To see the cur-
rent operation mode simply press the button
once (1 Fig. 4).
To change operation mode press the button
for between 2 to 10 seconds until the current
configuration flashing, each time the button is
pressed all possible functions are scrolled cycli-
cally according to the table (Fig. 5). After a few
seconds without doing any operation the circula-
tor memorises the selected mode and goes back
to operation display.
- Constant curve: the pump operates with a con-
tant curve. The circulator working point will
move up or down according to the system's
demand.
- PWM Profile: do not use this operation
mode.
Description
The circulator pump cannot restart
automatically due to an anomaly
Voltage off range
The circulator is locked due to power
supply too low or serious malfunction

Selection button lock. The button has a feature
that locks its operation to prevent accidental
modifications, to lock the control panel it is
necessary to press button (1) longer than 10
seconds (during which the current configuration
flashes), the active lock is signalled by all LEDs of
the control panel flashing. To unlock the button
press again longer than 10 seconds.
Real time diagnostics: in the event of malfunc-
tion the LEDs provide information on the circu-
lator operation status, see table (Fig. 6):
Diagnostics
Wait for the circulator to make automatic
release attempts or manually release the mo-
tor shaft acting on the screw in the centre of
the head.
If the anomaly persists replace the circulator.
Check power supply
Check the power supply, if the anomaly persists
replace the circulator
