To restore operation (unblock alarms):
Faults A01-02-03
Set the function selector to OFF , wait 5-6 seconds and return to
the required setting.
If the unblock attempts do not reactivate the boiler, please request
support from the Technical Assistance Service.
Fault A04
The digital display shows the fault code together with the symbol .
Check the pressure shown on the water gauge:
If the pressure is less than 0.3 bar, set the function selector to
(OFF)
and adjust the filling valve until the pressure is between 1 and 1.5 bar.
Turn the function selector back to the required setting.
If there are frequent drops in pressure, please request support from
the Technical Assistance Service.
Fault A06
The boiler operates normally but does not guarantee a stable domestic
hot water temperature, which is set to around 50°C.
Please request support from the Technical Assistance Service.
Fault A07
Please request support from the Technical Assistance Service.
4.5
Temporary shutdown
During temporary absences, weekends, short holidays etc., set the
function selector to (OFF).
With the power mains ON and the gas supply active, the boiler is
protected by the systems:
-
Anti-freeze
This function is activated if the boiler water temperature falls below
5°C. The pump runs a 15 minute cycle every 2 hours as follows:
the pump stops when the boiler water temperature exceeds 10°C;
the burner is ignited to the minimum in heating mode when the
boiler water temperature falls below 5°C until the water temperature
reaches 30°C, after which a post-pump phase runs for 30 seconds.
-
Pump anti-block function
The pump is activated every 24 hours of standby and, in any event,
3 hours after the last DHW request.
4.6
Shutdown for long periods
If the
START
boiler will not be used for a long period of time:
- set the function selector to (OFF-unblock)
- turn the main system switch to “OFF”
- close the heating and domestic hot water system gas and water
cocks.
The anti-freeze and pump anti-block functions are disabled.
Empty the heating and DHW circuit if there is a risk of freezing.
4.7
Maintenance
Periodic maintenance is an “obligation” required by law and is essential
to the safety, efficiency and lifetime of the boiler.
It allows for the reduction of consumption, polluting emissions and
keeping the product reliable over time.
Before starting maintenance operations:
•
Perform the analysis of the combustion products to check the boiler
operation status then cut the electrical supply by turning off the
system’s general switch
•
Close the fuel and water taps of the heating and domestic hot water
system.
The appliance must be systematically controlled at regular intervals
to make sure it works correctly and efficiently and conforms to
legislative provisions in force.
