3.9 Filling the heating system (fig. 16)
Note: even if the boiler is fitted with a semi-automatic filling device, the
first filling operation must be carried out by turning the filler tap (B) with the
boiler off.
Once the hydraulic connections have been carried out, fill the heating
system. This operation must be carried out when the system is cold,carrying
out the following operations:
- open the caps of the lower (A) automatic air vent valve by two or three
turns; to allow a continuous venting of the air, leave the plug of the valve
A open
- make sure the cold water inlet tap is open
- open the filling tap (B) until the pressure indicated by the water pressure
gauge is between 1 and 1.5 bar
- re-close the filling tap.
b
The venting of the boiler takes place automatically via the two
automatic vent valve A positioned on the circulator.
3.10 Draining the heating system (fig. 16)
Before starting emptying, switch off the electricity supply by turning off the
main switch of the system.
- Close the heating system's valves.
- Connect a hose to the system drain valve (C).
- Manually loosen the system drain valve (C).
3.11 Emptying the domestic hot water system
Whenever there is risk of frost, the domestic hot water system must be
emptied in the following way:
- turn off the main water supply tap
- turn on all the hot and cold water taps
- drain the lowest points.

3.12 Circulator settings
Circulator residual discharge head
ΔP at
The boilers is equipped with an already hydraulically and electrically
boiler
connected circulator, whose useful available performance is indicated in
output
the graphs at page 252.
Pa
The circulator comes set from the factory with a 6 metre discharge head curve.
The boiler is equipped with an anti-blocking system which starts up an
180
operation cycle after every 24 hours in standby with the mode selector in
210
any position.
255

280
The "antiblocking" function is active only if the boiler is electrically
powered.

Operating the circulator without water is strictly forbidden.

If you need to use a different curve you can select the desired level on the

Below the main characteristics and the ways to set up their desired operation
are listed.

3.12.1 User interface

The user interface is made up of a button (A), a two-coloured red / green
601
LED (B) and four yellow LEDs (C) arranged in a row.

The user interface allows the operating performance to be viewed (operating
495 status and alarm status) and it also allows the circulator operating modes
to be set.
540
The performance, indicated by the LEDs (B) and (C) is always visible during
normal operation of the circulator whereas the settings can be carried out
by pressing the button (A).
3.12.2 Operating status indication
When the circulator is in operation the LED (B) is green. The four yellow
LEDs (C) indicate the electrical energy consumption (P1) as shown in the
following table.

Green LED on +
1 yellow LED on

(*) For the power (P1) absorbed by the circulator see the indications in the
"Technical Data" table.
3.12.3 Alarm status indication
If the circulator has detected one or more alarms the two-coloured LED (B)
will be red. The four yellow LEDs (C) indicate the type of alarm as shown
in the following table.
LED status
Red LED on +
1 yellow LED
on (LED 5)
Red LED on +
1 yellow LED

Red LED on +
1 yellow LED

b
If there are several alarms the circulator will display only the alarm
with the highest priority.
3.12.4 Display of active settings
With the circulator powered, press briefly on the button (A) to view the active
configuration of the circulator. The LEDs indicate the active settings.
In this phase no variations can be made to the circulator configuration. Two
seconds after the button (A) has been pressed the user interface returns to
the normal operating status display.
