Troubleshooting - Immergas HERCULES Solar 26 1 A Instruction Booklet And Warning

During the request for central heating "CH
ON" appears on the display (24) on the status
indicator (6) and at the same time as burner
ignition the flame presence indicator switches
on (8) with relative power scale and the indi-
cator (9 and 7) with the instantaneous outlet
temperature from the primary heat exchanger.
In the central heating phase, if the temperature
of the water contained in the plant is sufficient
to heat the radiators, the boiler can only func-
tion with the activation of the boiler pump.
Winter functioning mode with room central
heating
• Operation with Comando Amico Remoto
remote control (CAR) (Optional). In the case
of connection to the CAR remote control, the
boiler automatically detects the display and the
( ). symbol appears on the display. From
this moment all controls and adjustments are
referred to the CAR remote control. The stand-
by button " ", the reset button "C", the menu
entry button "D" and the DHW priority button
"B" however remain active.
Important: If the boiler is put into stand-by
(10) the "CON" connection error symbol will
appear on the CAR remote control. The CAR
remote control is however powered constantly
so as not to loose memorised programs.
• Operation with Super Comando Amico
Remoto remote control (Super CAR) (Op-
tional). In the case of connection to the Super
CAR remote control, the boiler automatically
detects the display and the (
appears on the display. From this moment it
is possible to make adjustments indifferently
from the Super CAR remote control or the
boiler. Except for the central heating tempera-
ture that is shown on the display but managed
by the Super CAR remote control.
Important: If the boiler is put into stand-by
(10) the "ERR>CM" connection error symbol
will appear on the Super CAR. The Super CAR
remote control is however powered constantly
so as not to loose memorised programs.
• "COMFORT" or "SAVING" DHW function.
Pressing button "B" on the display makes the
( ) symbol appear and the "COMFORT"
function is activated, which allows to have the
maximum amount of water available set ac-
cording to user requirements by adjusting the
selector switch (1). The production of the hot
water is guaranteed by the solar system and the
boiler.
Pressing button "B" again passes to "SAVING"
mode, signalled by the indicator (15 ) off. In
this way priority is given to the solar system to
produce DHW, thus guaranteeing a minimum
temperature of the water contained in the cyl-
inder of 45°C. In this mode it is also possible to
regulate the temperature of the water contained
in the cylinder by acting on the selector switch
(1).
• Functioning with external probe (Fig. 2-6)
optional. In the case of a system with optional
external probe, the boiler flow temperature
for room central heating is managed by the
external probe depending on the external
temperature measured (Par. 1.5 and par. 3.8
under "P66"). It is possible to modify the flow
temperature from -15°C to +15°C with respect
to the adjustment curve ( fig. 1-8 Offset value).
This correction, which can be activated using
selector switch (3) is kept active for any exter-
nal temperature measured. The modification
of the offset temperature is displayed using
the indicator (7). The indicator (4) shows the
current delivery temperature and after a few
seconds from the modification it is updated
with the new correction. The "SET" indication
appears on the display (Fig. 2-6). By turning the
selector switch (3) in a clockwise direction the
temperature increases and in an anti-clockwise
direction it decreases.

on (8) with relative power scale and the indi-

tion with the activation of the boiler pump.
Functioning in winter mode with external probe
From this moment the boiler functions automati-
cally. With no demand for heat (central heating
or domestic hot water production) the boiler goes
to "stand-by" function, equivalent to the boiler
being powered without presence of flame.
N.B.: it is possible that the boiler may start-up
automatically if the anti-freeze function is ac-
tivated.(13). Moreover, the boiler can function
for a brief period of time after a withdrawal of
domestic hot water in order to take the domestic
hot water circuit back into temperature.
Important: with the boiler in stand-by mode
( ) hot water cannot be produced and the
safety systems cannot be guaranteed, such as:
pump anti-block, anti-freeze and three way
anti-block.

2.6 TROUBLESHOOTING.

The Hercules Solar 26 1 A boiler signals any
anomalies by the flashing symbol (5) along
with the "ERRxx" indication on the indicator
(6) where "xx" corresponds to the error code
described in the following table. On any remote
control the error code will be displayed by means
of the same numerical code number represented
according to the following example (e.g. CAR =
Exx, Super CAR = ERR>xx).
Anomaly signalled
No ignition block
Safety thermostat block (over-hea-
ting), flame control anomaly
Flue safety thermostat block
Contacts resistance block
Flow probe anomaly
Insufficient system pressure
Storage tank probe anomaly
Configuration error
Fan anomaly

Important: the error codes 31, 37, 38 are not
shown on the CAR and Super CAR display.
For error codes 39, 40, 41 and 42 on the CAR
or Super CAR remote control display, they are
displayed with the General alarm code 22.
Ignition block. The boiler ignites automatically
with each demand for room central heating or
hot water production. If this does not occur
within 10 seconds, the boiler remains in stand-
by for 30 seconds, try again and if the second
attempt fails it will go into "ignition block"
(ERR01). To eliminate "ignition block" the Reset
button "C" 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. By switching the appliance on and
off the 5 attempts are re-acquired. On commis-
sioning or after extended inactivity it may be
