Boiler ignition. Before switching on the boiler, check
that the system is filled with water and that gauge (6)
indicates a pressure of 1÷1,2 bar.

N.W.: When the main switch (5) is positioned on the
above mentioned positions, the green indicating lamp

With the main switch (5) set on position (
the Amico Remote Control connected to the boiler,
the two selectors (1) and (2) are inhibited. The
functioning parameters of the boiler are settable
directly on the Amico Remote Control panel.

Ignition block. Each time heating or hot water
production is required the boiler is activated
automatically. If this does not occur within 10
seconds, the boiler activates an "ignition block"
(indicator lamp 7). To eliminate the block, rotate the
main switch (5) temporarily to the Reset position. On
initial ignition or following a prolonged period of disuse
the ignition block may need to be inhibited. If this
function is activated repeatedly, contact a qualified
technician for assistance (e.g. Immergas Technical
Services Centre).
Temperature overload block. During operation, if
a fault causes a temperature overload condition, the
boiler operation is shut-off (indicating lamp 7 flashing).
To eliminate the over heat lock is necessary to turn
momentary the main switch (5) to Reset position. If
the problem is frequent, contact an authorised
technician (e.g. Immergas Technical Service).

heating temperature selector (1) is inhibited, the
domestic hot water temperature is controlled by
selector (2). With the main switch (5) set to (
position, the heating temperature selector (1) is
used to adjust the temperature of radiators, while
selector (2) is used to adjust the domestic hot water
temperature. Rotate clockwise to increase the
temperature and counterclockwise to decrease.
Now the boiler works automatically. Without heating
demands (heating system and domestic hot water),
the boiler moves on stand-by position, equivalent to
boiler supplied without flame presence (indicating
lamp number 4 ignited). Every time the burner works,
this situation is indicated through the yellow indicating
lamp of flame presence (3) on the control panel.

fan is blocked or when the ignition-detection control
box is defected. If normal conditions are restored,
the boiler re-start to work without requiring reset. If
anomalies persists contact the authorised technician

Central heating NTC sensor fault. If ignition control
box detects a fault of central heating NTC, the boiler
does not start; is necessary to call an authorised
technician (e.g. Immergas Technical Service).
Sanitary NTC sensor fault. If ignition control box
