2.4 USE OF THE WATER HEATER.
Ignition (Fig. 2-1). Before ignition, check that
the DHW inlet valve is open.
- Open the gas cock upstream from the water
heater.
- Press the button (1) until the display switches
on; pressing the button passes cyclically from
the "off ", "stand-by" and "on" state of the
appliance.
- Regulate the DHW temperature according to
requirements by turning the selector (3).
Turning in a clockwise direction the
temperature increases and in an anti-clockwise
direction it decreases.
From this moment the water heater functions
automatically. If there is no request for DHW, it
goes to "Stand-by" which is equal to water heater
powered without flame presence. The display
shows the temperature of the water inside the
water heater (5). Each time the burner ignites,
the relative flame present symbol is displayed
(11) with relative power scale (10). Moreover, the
indication of the instant temperature supplied
by the water heater is supplied.
• "Stand-by" mode. Repeatedly press the
button (1) until the (
) symbol appears. The
water heater is inactive from this moment.
The indication of any anomalies is however
guaranteed.
N.B.: in these conditions the water heater is
considered still powered.
• "Off " mode. Press button (1) repeatedly until
the display switches off. In this way the water
heater is off completely.
N.B.: in these conditions the water heater
is considered still live even if there are no
functions active.
2.5 FAULT AND ANOMALY SIGNALS.
The water heater signals out anomalies by
flashing on the display and relative error codes,
listed on the table, are displayed.
Anomaly signalled
No ignition block
Over-heating (safety) thermo-
stat block
Domestic hot water probe
anomaly
Maximum N° of reset
Flue pressure switch failure
Domestic hot water inlet
probe anomaly
Parasite flame
Push button control panel
anomaly
Low power supply voltage
Ignition block. The water heater ignites
automatically with each demand for hot water
production. If this does not occur within 10
seconds, the water heater goes into ignition block
(code 01). To eliminate "ignition block" the Reset
button (2) must be pressed. On commissioning
or after extended inactivity it may be necessary to
eliminate the "ignition block". If this phenomenon
occurs frequently, contact a qualified technician
for assistance (e.g. Immergas After-Sales Technical
Assistance Service).
Overtemperature thermostat block. During
normal functioning, if a fault causes excessive
overheating internally, the water heater goes into
overtemperature block (code 02). After allowing
to cool, eliminate the "overtemperature block" by
pressing the Reset key (2). If this phenomenon
occurs frequently, contact a qualified technician
for assistance (e.g. Immergas After-Sales Technical
Assistance Service).
Domestic hot water probe anomaly. If the board
detects an anomaly on the delivery probe (code
06), the water heater will not start; contact a
qualified technician for assistance (e.g. Immergas
After-Sales Technical Assistance Service).
Maximum N° of reset. To eliminate any "anomaly"
the Reset button (2) must be pressed. The Anomaly
can be reset 5 times consecutively, after which the
function in inhibited for at least one hour. One
attempt is gained every hour for a maximum of
5 attempts.
Flue gas pressure switch failure. This occurs if the
intake or exhaust pipes are blocked, in case of a fan
fault or a fault on the flue gas pressure switch (code
11). If normal conditions are restored the water
heater restarts without having to be reset. If this
anomaly persists, contact a qualified technician
for assistance (e.g. Immergas After-Sales Technical
Assistance Service).
Domestic hot water inlet probe anomaly. If the
board detects an anomaly on the domestic hot
water NTC probe, the water heater signals the
anomaly. In this case the water heater continues to
produce domestic hot water but not with optimal
performance. A qualified technician however
must be called (e.g. Immergas After-Sales Service).
Parasite flame. This occurs in case of a leak on the
detection circuit or anomaly in the flame control
unit.(code 20), try to reset the water heater. If the
anomaly continues contact a qualified technician
code
(e.g. Immergas After-Sales Technical Assistance
displayed
Service).
(flashing)
Push button control panel anomaly. This occurs
01
when the circuit board detects an anomaly on the
push button control panel. If normal conditions are
02
restored the water heater restarts without having
to be reset. If this anomaly persists, contact a
06
qualified technician for assistance (e.g. Immergas
After-Sales Technical Assistance Service).
08
Low power supply voltage This occurs when the
power supply voltage is lower than the allowed
11
limits for the correct functioning of the water
heater. If normal conditions are restored the
12
water heater restarts without having to be reset.
If this phenomenon occurs frequently, contact a
20
qualified technician for assistance (e.g. Immergas
After-Sales Technical Assistance Service).

2.6 INFORMATION MENU.
37
Pressing the button (2) for 8 seconds, the
"Information menu" is activated, which allows to
display some water heater functioning parameters.
To scroll the various parameters, press the button
(2), to exit the menu, press the button (1) or wait
for 15 minutes.
List of parameters.
2.7 SWITCH-OFF OF THE WATER
Press the button (1 Fig. 2-1) (
display is switched off completely.
N.B.: in these conditions the water heater is
considered still powered.
Disconnect the external omnipolar water heater
switch and close the gas cock upstream of the
appliance. Never leave the water heater switched
on if left unused for prolonged periods.
2.8 EMPTYING THE WATER HEATER.
To empty the water heater, close the cold water
inlet valve and open the hot water valve lower
down in the water network in the room.
2.9 ANTI-FREEZE PROTECTION
The water heater can be equipped with an
optional anti-freeze kit, which protects it from
freezing to outdoor temperatures of -15°C. For
correct installation of the kit and especially
to guarantee appropriate functioning, the
instructions supplied with the kit itself must
be followed.
2.10 CASE CLEANING.
Use damp cloths and neutral detergent to clean
the water heater casing. Never use abrasive or
powder detergents.
2.11 DECOMMISSIONING.
In the event of permanent shutdown of the
water heater, contact professional staff for
the procedures and ensure that the electrical,
water and gas supply lines are shut off and
disconnected.
