PRE-HEATING (faster hot water)
Turning the domestic hot water adjustment knob to the symbol
activates the pre-heating function. Bring the domestic hot water
temperature adjustment knob back to the required position. This
function keeps the water in the domestic hot water exchanger to
reduce standby times when a request is made. When the pre-heating
function is enabled, the display shows the symbol . The display
indicates the outlet temperature of the heating water or the domestic
hot water based upon the request in progress. During burner ignition,
following a pre-heating request, the monitor shows the flashing
symbol. To deactivate the pre-heating function, rotate the domestic
hot water temperature adjustment knob back to the symbol
. The
symbol switches off. Return the domestic hot water temperature
adjustment knob to the desired position. The function is not active
when the boiler is OFF: function selector on
OFF.
ADJUSTMENT OF THE TEMPERATURE OF DOMESTIC HOT
WATER
To adjust the domestic hot water temperature (for baths, showers,
kitchen etc.), turn the dial with the
symbol clockwise to increase
the value, or anticlockwise to decrease the value (mi. value 37°C -
max. value 60 °C). The boiler is in standby until the burner switches
on following a heat request. The boiler continues to function until
the temperatures set on the boiler are reached, or the heat request
terminates; it will then go back to standby. In the case of a temporary
stop the digital display shows the fault code.
HEATING TEMPERATURE CONTROL FUNCTION(C.T.R.)
Turn the heating water temperature selector into sector highlighted
with white markers to activate the H.T.C. self-adjusting system:
based on the temperature set on the ambient thermostat and the time
employed to reach it, the boiler varies automatically the heating water
temperature reducing the operating time, allowing great operation
comfort and energy saving.

RESET FUNCTION
To restore the operation, bring the function selector to OFF, wait
5-6 seconds and then bring the function selector back to the desired
position. At this point, the boiler will restart automatically.
N.B. If the attempts to reset the appliance do not activate operation,
contact the Technical Assistance Centre.
Temporary switch-off
In the event of temporary absences (weekends, short trips, etc.) set
the mode selector to
(off/reset).
While the electrical supply and the fuel supply remain active, the boil-
er is protected by the systems:
Antifreeze
this function is activated when the temperature of the water in the
boiler drops below 5°C. The circulation pump runs for a timed period
of 15 minutes every 2 hours, with the following logic: the circulation
pump switches off when the water temperature in the boiler exceeds
10°C; the burner lights and operates at the lowest heating setting
when the water temperature in the boiler drops below 5°C, and con-
tinues heating until the water temperature reaches 30°C, after which
a 30 second post-circulation cycle is performed.
Circulator anti-blocking
the circulator is activated every 24 hours when stopped and in any
case three hours after the last domestic hot water drawing.
Switching off for long periods
In the case of prolonged periods with the boiler not in use, perform the
following operations:
- Position the function selector on
(OFF - RESET.
- Turn the main system switch to “OFF”.
- Turn off the fuel and water taps of the heating and domestic hot
water system.
In this case, the anti-freeze and anti-locking systems are deac-
tivated.
Drain the heating and domestic hot water systems to prevent
freezing.
