To end this function press again the keys " " and " " for the cycle time or wait 12 minutes for the process to nish.
1.9. Children safety
It is possible to set the keys to lock automatically, so as to prevent they are accidentally pressed; to enable this function, set the TSP 24 to
1. 2 minutes after the last key has been tapped, the same will get blocked. To unlock it, press the key “ ” for the cycle time.

17
1.10. Boiler operation
1.10.1. Switching on the boiler
These instructions assume that the boiler has been installed by a company authorised for the purpose, that the first
started up has been already performed and the boiler has been prearranged for a correct operation.
- Open the gas supply interception valve;
-position to ON the switch on the electrical system upstream the boiler. The display comes on indicating the type of gas, the power set
and the function active in that moment (see Table 3 and Table 4);
- select the boiler operation system by pressing the related key " " (Ag. 1) OFF/SUMMER/WINTER (par. 1.2);
- set the temperature value of the heating water (see paragraph 1.10.2);
- set the temperature value of the domestic hot water (see paragraph 1.10.3);
- set on the house thermostat (if present) the necessary ambient temperature value.
CAUTION
After a long inactivity period of the boiler, especially for boilers operating with propane, there could be difficulty upon ignition.
Therefore, prior to switching on the boiler, start up a gas operated appliance (e.g. a stove).
Despite this, the boiler could get blocked once or twice. Restore then the operation of the same by pressing “ ” (B fig. 1).
1.10.2. HEATING function
To adjust the temperature of the heating water hold for the cycle time the key “ ” (Cg. 1) and then use on the keys " " or " " (Eor
Fg. 1).
The adjustment range of the heating temperature depends on the operating range selected:
-standard range: from 20°C to 80°C;
-low range: from 20°C to 47°C.
The operation range must be selected by the installer or by an Authorized Service Centre (see section 3.2.11).
While the temperature is being set, the heating symbol on the screen ashes (2g. 1) and the value being set for the heating water tem-
perature is displayed.
When the heating system requires heat, the symbol of heating on the display ashes (2g. 1) and the instantaneous temperature of the
heating water in delivery is displayed. The burner symbol ON (1g. 1) comes out only when the burner is running.
The waiting time between one ignition and the next of the boiler, meant to avoid frequent switching on and off of the boiler during heating
operation, ranges between 0 and 10 minutes (default 3), and can be edited in the parameter P05.
1.10.3. DOMESTIC Function
To adjust the temperature of the domestic hot water, hold for the cycle time the key “ ” (Dg. 1) then use the keys " " or " " (Eor F
g. 1).
This function has always priority over the heating function.
The temperature adjustment of the domestic hot water ranges from 10°C to 60°C.
While the temperature is being set, the heating symbol on the screen ashes (7g. 1) and the value being set for the domestic hot water
temperature is displayed.
When the heating system requires heat, the symbol of heating on the display ashes (7g. 1) and the instantaneous temperature of the
heating water is displayed. The burner symbol ON (1g. 1) comes out only when the burner is running.
1.10.4. ANTIFREEZE Function
The boiler is equipped with an anti-freeze protection system enabled with the operating modes: OFF/SUMMER/WINTER/.
The antifreeze function protects the boiler only, not the entire heating system.
The heating system can also be effectively protected from freezing by using specic antifreeze products suitable for systems made from
several metals.
Do not use antifreeze products for vehicles motors and check the effectiveness of the product in time.
If the burner could not get switched on due to lack of gas, the antifreeze functions stay enabled by feeding the circulators.

18
1.10.4.1. Antifreeze function in delivery
The delivery line antifreeze function has two phases:
If the temperature sensor of the heating water detects a water temperature value < TSP 38 + 2°C, the boiler starts the circulators and stays
switched on until the temperature of the heating water reaches a value > TSP 38 + 5°C.
In case the boiler blocks, the pump circulation is however ensured.
If the heating water temperature sensor detects a temperature value < TSP 38, the boiler starts with the burner at the lowest power value.
Once a temperature value > 42°C is reached, the burner goes off while the circulator keeps operating for about 150 seconds.
In case the boiler blocks, the pump circulation is however ensured.
1.10.4.2. Antifreeze function for the domestic hot water plates
The antifreeze function protects as well the domestic hot water circuit.
When the temperature sensor of the domestic hot water detects a water temperature of 5°C, the boiler gets switched on and stays on
the minimum thermal power value until the temperature of the domestic water reaches a temperature of 7°C (the diverter valve is set on
domestic hot water position).
During the antifreeze phase in domestic hot water, the temperature is continuously detected by the sensor on the delivery line and, as
soon as it reaches the value of 42°C, the burner gets switched off. The burner is switched back on if during antifreeze phase the delivery
temperature drops below 5°C.
In case the boiler blocks, the pump circulation is however ensured.
1.10.5. Pump and diverter valve anti-block function
In case the boiler stays inactive and connected to the power mains, every 24 hours the circulation pump and diverter valve are activated
for a short period of time (30 seconds) to prevent them from blocking.
1.10.6. Operation with external probe (option)
The boiler can be connected to a probe that measures the outside temperature (this option is not mandatory; supplied by the manufactur-
er). Note: the temperature outside the boiler adjusts automatically the temperature of the heating water, by increasing it if the external tem-
perature drops and decreasing it when the external temperature rises, to improve comfort and save energy. The maximum temperatures
of the standard and low range are, however, met.
This boiler operation type is dened as being "sliding temperature operation".
The heating water temperature varies according to a program written in the microprocessor of the boiler electronics.
With external probe, the key “ ” (C fig. 1) loses its temperature setting function for the heating water and, instead, allows changing
the “dummy” temperature, i.e. the theoretical temperature desired in the environments to be heated.
On setting the temperature, the dummy ambient temperature value ashes on the display, while the value being set is displayed.
For the optimal adjustment of the curves it is recommended to set it to about 20°C. For further details on the sliding temperature operation
refer to paragraph 3.2.14.
Use exclusively original external probes provided by the manufacturer.
Using external probes other than original, not supplied by the manufacturer, having technical characteristics
different from those required by the electronic management, can affect the operation of the external sensor
and of the boiler.
1.10.7. Operation with Remote Control (option)
The boiler can be paired to a remote control (option not mandatory, supplied by the manufacturer), that allows managing remotely many
parameters of the boiler, for instance:
- select the boiler operation mode;
- select the ambient temperature;
- select the temperature of the heating system water;
- select the temperature of the domestic hot water;
- program the start-up time of the heating system and the activation timing of a possible external boiler (option);
- display boiler diagnostics;
- unblock the boiler;
and other parameters.
To connect the remote control refer to the paragraph 3.2.13 and to the user’s manual annexed to the remote control.
Use exclusively original remote controls supplied by the manufacturer.
Using remote controls other than original, not supplied by the manufacturer, can affect the operation of the
remote control itself and of the boiler.

19
1.11. Boiler blocking
In case of malfunctions, the boiler gets automatically blocked. To acknowledge the boiler operation mode refer to Table 3 and Table 4.
To acknowledge the possible causes of the malfunction check also paragraph “7. Troubleshooting” at the end of this manual.
Proceed then as described below, depending on the cause of the blocking.
1.11.1. Burner blocked
If the burner gets blocked due to the lack of ame, the ashing code E06 is displayed on the screen. In this case, proceed as follows:
- check, by switching on a stove, for instance, if the gas valve is open and if gas is supplied;
-after having checked to make sure gas is normally supplied, unlock the burner by pressing the key “ ” (Bg. 1): if the appliance does
not start and gets block after the third attempt, contact an Authorized Service Centre or personnel qualied for maintenance.
If the burner gets frequently blocked, meaning there is a recurring fault in its operation, contact an Authorized Service Centre or personnel
qualied for maintenance.
1.11.2. Blocking due to over-temperature
In case of over-temperature on the delivery line, the boiler gets blocked and the ashing code E07 is displayed on the screen.
In this case please contact an Authorized Service Centre or personnel qualied for maintenance.
1.11.3. Blocking due to missing draught (fumes blocking)
In case of malfunction of the air suction and/or fumes exhaust systems, the boiler gets blocked and the ashing code E13 or E96 is dis-
played on the screen (the fumes probe has tripped).
In this case please contact an Authorized Service Centre or personnel qualied for maintenance.
1.11.4. Block due to low water pressure in the system
In case of ashing code error E02 indicating the blocking due to low system pressure, fed the system by acting on the lling tap g. 2 (for
SV models the tap is located on the cold water inlet pipe).
The error E02 is displayed when the system pressure drops below 0.5 bar and resets automatically when the pressure of the system has
exceeded the threshold of 1.1 bar.
The pressure value in the cold boiler must be 1÷1.3 bar.
To restore the water pressure value follow the indications given below:
- pull down on the knob to lower it;
- rotate the lling valve knob (g. 2) counter-clockwise to feed water into the boiler;
- keep the valve open until on the control panel is displayed a pressure value of 1÷1.3 bar;
- shut off the valve by rotating the knob clockwise;
- push upwards the knob to t it back.
If the boiler gets blocked again, contact an Authorized Service Centre or personnel qualied for maintenance.
After the operation has been completed, make sure to close the safety Plexiglass door. If the valve has not
been tightly closed, the pressure could increase above 2.6 bar, and have displayed on the screen the error
E03; in this case open the safety valve of the heating system and drain out some water.

1.11.5. Alarm caused by the temperature probes failure
If the burner gets blocked due to the water temperature probe malfunction, the display shows the codes:
-E05 for the heating probe.
In this case the boiler does not work.
-E04 for domestic hot water probe.
In this case the domestic hot water function is performed with modulation on the heating sensor.
-E16 for the return line probe.
In this case the boiler continues to run.
In all four cases contact an Authorized Service Centre or personnel qualified for maintenance.
1.11.6. Blocking caused by the malfunction of the fan
The fan operation is constantly monitored; in case of burner malfunction, the fan is switched off and the ashing code E15 is displayed on
the screen.
This status stays the same until the fan returns to normal operating parameters.
If the boiler does not resume operation and remains in this condition, contact an Authorized Service Centre or personnel qualified
for maintenance.
1.11.7. Alarm due to a faulty connection to the remote control (option)
The boiler acknowledges the presence of the remote control (option not required).
If the remote control is connected and subsequently the boiler does not receive information from it, the boiler attempts to re-establish
communication for a period equal to 60 seconds; after this time has lapsed, on the remote control screen is displayed the code E43.
The boiler will keep running according to the settings made on the control panel, ignoring the settings made on the remote control.
In this case please contact an Authorized Service Centre or personnel qualified for maintenance.
1.12. Maintenance
Provide for periodic maintenance of the boiler according to the schedule specified in the related section of this manual.
Proper maintenance of the boiler allows it to work under the best conditions, to protect the environment and to ensure the safety
of persons, animals and objects.
The routine maintenance operations of the boiler must be carried out by qualified personnel.
For maintenance and repairs operations the manufacturer recommends its clients to contact its network of Authorised Service
Centres, which are trained to perform the above interventions.
1.13. Notes for the user
The user has free access only to the boiler parts whose operation does not require the use of tools and/or equipment; it is, there-
fore, not permitted to remove the boiler panel to intervene on its inner parts.
Nobody, including the qualified staff, is authorized to make changes to the boiler.
The manufacturer declines any liability for damage to persons, animals and objects generated by having tampered with the boiler
or by wrong interventions on the same.
If the boiler remains inactive and disconnected from the power supply for a long time, the pump could require being unblocked.
This operation, which involves disassembling of the panel and the access to the boiler inner parts, must be performed by qualified
personnel.
The pump blocking can be avoided if the system is subjected treatment with specific protective products, suitable for systems
made from several metals.
