Boiler ignition.
Before lighting, make sure the system is full
of water and that the manometer (6) indicates a pressure of
1÷1.2 bar.
- Open the gas cock downstream of the boiler.
Turn main switch (5) to Domestic/Remote Friend Control
(
) or Domestic and Heating (
).
• Operation with Remote Friend Control (Optional). With
the switch (5) set to (
) and Remote Friend Control
connected the boiler sensors (2) and (3) are cut out; the
wording “CE” (External Commands) appears on the dis-
play. e boiler adjustment parameters are settable from
the Remote Friend Control panel.
•
Operation without Remote Friend Control. With the
switch (5) set to (
) the heating adjustment selec-
tor (2) is cut out, and the domestic water temperature
is adjusted by selector (3). With the switch set to (
)
the heating adjustment selector (2) is used to regulate the
temperature of radiators, whereas selector (3) is used for
the domestic water. Turn the selectors clockwise to increase
the temperature, and anticlockwise to decrease it.
Boiler operation is now automatic. Every boiler ignition is
signalled by means of the indicator (9) on the control panel.
When the selector (2) or (3) is turned, the temperature set-
ting at that moment is shown on the display (8), and at the
same time indicator (1) or (4) flashes, depending on the
selector being used; after 5 seconds the current boiler delivery
temperature value appears on the display (8).
Signalling and diagnostics - Display (8).
During normal
boiler operation the boiler delivery temperature value is dis-
played. With the boiler on Stand-by an illuminated horizon-
tal segment appears on the display. In case of malfunction
or anomaly, the temperature is replaced by the relative error
code flashing.
1 = Ignition block
2 = Block due to the overtemperature safety thermostat
activation
5 = Delivery sensor fault
6 = Domestic circuit sensor fault
10 = Failed water flow switch activation
14 = Flame control unit fault
16 = Fan fault
17= Fan rpm incorrect
26= Water flow switch fault
31 = Remote Friend Control not compatible
e user can reset boiler blocks signalled by codes 1 and 2,
by pressing the boiler reset pushbutton (7) or the reset button
on the Remote Friend Control (if connected); if the block
persists request the intervention of a qualified technician (eg.
Immergas Technical Assistance Service).
Boiler block signalled by code 10 can be due to: lack of water
in the system, blocked or faulty circulating pump. In the first
case check that the pressure gauge (6) indicates a value of
1÷1.2 bar; in the latter two, call a qualified technician (e.g.
Immergas Technical Assistance Service).
All the other signals (codes: 5-6-14-16-17-26-31) require
the intervention of a qualified technician (e.g. Immergas
Technical Assistance Service).
Boiler shutdown.
Turn off the main switch (5), turning it
to “0”, and close the gas cock ahead of the appliance.
Never leave the boiler switched on if not used for prolonged
periods.
