After 2 minutes from pressing the last key, they will be locked. To unlock, simply press the " " button for the cycle time.

17
1.10. Operation of the boiler
1.10.1. Power on
These instructions assume that the boiler has been installed by an authorized installer, the first ignition has been
carried out and the boiler has been set up for correct operation.
- Open the gas shut-off valve;
- set the switch on the electrical system upstream of the boiler to the ON position. The display lights up indicating the type of gas, the
power set and the function active at that moment (see Table 3 and Table 4);
- choose the boiler operating system by pressing the appropriate button " " (A fig. 1) OFF / SUMMER / WINTER (par. 1.2);
- set the desired temperature value for the heating water (see paragraph 1.10.2);
- set the desired temperature value for domestic hot water (see paragraph 1.10.3);
- set the desired room temperature value on the room thermostat inside the house (if present).
ATTENTION
After a long period of inactivity of the boiler, especially for boilers running on propane, it may be difficult to ignite. Therefore,
before lighting the boiler, turn on another gas appliance (for example a stove). Despite this, the boiler could block once or twice.
Then restore its operation by pressing the button " " (B fig. 1).
1.10.2. HEATING function
To adjust the heating water temperature, hold down the " " button (C fig. 1) for the cycle time and then press the "
" Or " "(E or F fig. 1).
The heating temperature adjustment range depends on the selected operating range:
- standard range: from 20 ° C to 80 ° C;
- reduced range: from 20 ° C to 47 ° C.
The selection of the operating range must be made by the installer or by an Authorized Service Center (see paragraph 3.2.11).
While setting the temperature, the heating symbol flashes on the screen (2 fig. 1) and the value that is being set for the heating water
temperature is indicated.
When the heating system requires heat, the heating symbol flashes on the display (2 fig. 1) and the instantaneous temperature of the
heating delivery water is displayed. The burner on symbol (1 fig. 1) appears only when the burner is operating.
The waiting time between one ignition and the next of the boiler, which serves to avoid frequent switching on and off of the boiler during
heating operation, is between 0 and 10 minutes (default 3), which can be modified with parameter P05.
1.10.3. SANITARY function
To adjust the temperature of the domestic hot water, hold down the " " button (D fig. 1) for the cycle time and then press the " " or
" " buttons (E or F fig. 1).
This function always takes precedence over the heating function.
The adjustment range of the domestic hot water temperature ranges from 10 ° C to 60 °C.
During the temperature setting, the heating symbol flashes on the screen (7 fig. 1) and the value that is being set for the domestic hot
water temperature is indicated.
When there is a request for domestic hot water, the heating symbol flashes on the display (7 fig. 1) and the instant water temperature is
displayed. The burner on symbol (1 fig. 1) appears only when the burner is operating.
1.10.4. ANTIFREEZE function
The boiler is equipped with an antifreeze protection system active in the operating modes: OFF / SUMMER / WINTER /.
The antifreeze function protects only the boiler, not the entire heating system.
The heating system can also be effectively protected from freezing by using specific antifreeze products suitable for multi-metal systems.
Do not use antifreeze products for car engines and check the effectiveness of the product over time.
If it is not possible to ignite the burner due to lack of gas, the antifreeze functions are in any case activated by feeding the circulators.

18
1.10.4.1. Delivery antifreeze function The flow antifreeze
function has two phases:
If the heating water temperature sensor measures a water temperature <TSP 38 + 2 °C, the boiler starts the circulators and stays on until
the heating water temperature reaches a temperature> TSP 38 + 5 °C .
In the event that the boiler goes into lockout, the circulation of the pump is guaranteed.
If the heating water temperature sensor measures a water temperature <TSP 38, the boiler starts with the burner at minimum power. When
a temperature> 42 ° C is reached, the burner switches off and the post-circulation of the circulators continues for 150 seconds.
In the event that the boiler goes into lockout, the circulation of the pump is guaranteed.
1.10.4.2. Plate sanitary antifreeze function
The antifreeze function also protects the sanitary circuit. When the sanitary water temperature sensor measures a water temperature of 5 °
C, the boiler switches on and stays on at the minimum heat output value until the sanitary water temperature reaches a temperature of 7 °
C ( the diverter valve is placed in the sanitary position).During the antifreeze phase in DHW, the temperature detected by the flow probe is
continuously checked and if this reaches the value of 42 ° C, the burner is switched off. The burner is re-ignited if the request for operation
in the anti-freeze phase is still present and the flow temperature drops below 5 ° C.In the event that the boiler goes into lockout, the
circulation of the pump is guaranteed.
1.10.5. Pump anti-blocking function and diverter valve
In the event that the boiler remains inactive and connected to the mains, every 24 hours the circulation pump and the diverter valve are
activated for a short period (30 seconds), in order to prevent them from locking up.
1.10.6. Operation with external probe (optional)
The boiler can be connected to a probe that measures the external temperature (optional not mandatory, supplied by the manufacturer).
Once the outside temperature is known, the boiler automatically adjusts the temperature of the heating water, increasing it when the
outside temperature decreases and decreasing it when the outside temperature increases, thus improving the environmental comfort and
saving fuel. The maximum temperatures of the standard and reduced ranges are nevertheless respected.This boiler operation is called
“sliding temperature operation”.The variations in the temperature of the heating water occur according to a program written in the
microprocessor of the boiler electronics.
With an external probe, the " " button (C fig. 1) loses its function of setting the temperature of the heating water and instead
allows you to change the fictitious room temperature, that is the theoretical temperature desired in the rooms to be heated. While setting
the temperature, the fictitious room temperature value flashes on the display and the value being set is indicated.
For an optimal adjustment of the curves, a position close to 20 ° C is recommended. For a detailed explanation of the sliding temperature
operation, refer to paragraph 3.2.14.
Use only original external probes, supplied by the manufacturer.
The use of non-original external probes, not supplied by the manufacturer, if they have different technical
characteristics from those required by the management electronics, may affect the operation of the
external probe itself and of the boiler.
1.10.7. Operation with Remote Control (optional)
If the user so wishes, it is possible to connect the boiler to a Remote Control (optional not mandatory, supplied by the manufacturer),
which allows you to manage many boiler parameters, for example:
-selection of the boiler status;
-selection of the desired room temperature;
-selection of the water temperature of the heating system;
-selection of the domestic hot water temperature;
-programming the ignition times of the heating system and the activation times of any external boiler (optional);
-display of boiler diagnostics;
-boiler release;
-and other parameters.
-To connect the Remote Control, refer to paragraph 3.2.13 and the instruction booklet attached to the Remote Control.
Use only original Remote Controls, supplied by the manufacturer.
The use of non-original Remote Controls, not supplied by the manufacturer, may affect the operation of the
Remote Control itself and of the boiler.

19
1.11. Boiler lockout
When operating anomalies occur, the boiler automatically shuts down. Refer to Table 3 and Table 4 to recognize the boiler operating
status.To recognize the possible causes of the malfunction, see also paragraph “7. Technical problems table ”at the end of this booklet.
Depending on the type of block found, proceed as described below.
1.11.1. Burner lockout
In the event of burner lockout due to no flame, the E06 code flashes on the display. In this case, proceed as follows:
- check that the gas cock is open and that there is gas in the network, for example by lighting a stove;
- having checked the presence of fuel, unblock the burner by pressing the " " button (B fig. 1): if the appliance does not restart and
returns to lockout, on the third attempt contact an Authorized Service Center or qualified personnel for maintenance .
If the burner shuts down frequently, a sign of a recurring malfunction in operation, contact an Authorized Service Center or qualified
personnel for maintenance.
1.11.2. Overtemperature lockout
In case of overheating of the supply water, the boiler is blocked and the code E07 flashes. In this case, contact an Authorized Service
Center or qualified personnel for maintenance.
1.11.3. Block due to lack of draft (smoke block)
In the event of a malfunction of the air intake and / or flue gas exhaust systems, the boiler is blocked, the display shows the flashing code
E13 0 E96 (intervention of the fumes probe).In this case, contact an Authorized Service Center or qualified personnel for maintenance.
1.11.4. Block due to insufficient water pressure in the system
If the E02 blocking error due to insufficient system pressure flashes, fill the system by acting on the filling tap in fig. 2 (for SV models the
tap is located on the cold water inlet pipe).
Error E02 is displayed when the system pressure falls below the value of 0.5 bar and resets automatically when the system pressure
exceeds the threshold of 1.1 bar.
The pressure value with the boiler cold must be 1 ÷ 1.3 bar.
To restore the water pressure value, proceed as follows:
- pull the knob down to remove it;
- turn the filler tap knob (fig. 2) anticlockwise to allow the water to enter the boiler;
- keep the tap open until a pressure value of 1 ÷ 1.3 bar is reached on the control panel;
- close the tap by turning the knob clockwise;
- push the knob upwards to make it retract.
If the boiler locks up again, contact an Authorized Service Center or qualified personnel for maintenance.
At the end of the operation, close the filling tap well. If the tap is not closed properly, due to an increase in
pressure above 2.6 bar, the presence of error E03 on the display and subsequently the opening of the
safety valve of the heating system and the leakage of hot water could occur. -here.

1.11.5. Alarm due to temperature probe malfunction
In the event of a burner lockout due to a malfunction of the temperature probes, the following codes appear on the display:
-E05 for the heating probe.
In this case the boiler does not work.
-E04 for the DHW probe (Play models only).
In this case the DHW function is performed with modulation on the central heating probe.
-E12 for the boiler probe (Play SV models only).
-E16 for the return probe.
In this case the boiler continues to operate.
In all four cases, contact an Authorized Service Center or qualified personnel for maintenance.1.11.6.
Block due to fan malfunction
The operation of the fan is constantly monitored and in the event of its malfunction the burner is switched off and the display shows the
flashing code E15.
-This state is maintained until the fan returns to normal operating parameters.
If the boiler does not restart and remains in this condition, contact a qualified Service Center or Authorized for maintenance.
1.11.7. Alarm due to malfunction of the connection to the Remote Control (optional)
The boiler recognizes the presence of the Remote Control (optional not mandatory).
If the Remote Control is connected and subsequently the boiler does not receive information from the Remote Control, the boiler attempts
to re-establish communication for a period of 60 seconds, after which the code E43 appears on the Remote Control display.
The boiler will continue to operate according to the settings made on the control panel, ignoring the settings made on the Re-motion
Control.
In this case, contact an Authorized Service Center or qualified personnel for maintenance.
1.12. Maintenance
Provide periodic maintenance of the boiler according to the schedule specified in the appropriate section of this booklet.
Proper maintenance of the boiler allows it to work in the best conditions, respecting the environment and in complete safety for
people, animals and things.
Maintenance of the boiler must be carried out by qualified personnel.
The manufacturer advises its customers to contact the network of its Authorized Service Centers for maintenance and repair
operations, which are trained to perform the above operations in the best possible way.
1.13. Notes for the user
The user has free access only to the parts of the boiler whose operation does not require the use of tools and / or tools: he is
therefore not authorized to disassemble the boiler panel and to intervene inside it.
No one, including qualified personnel, is authorized to make modifications to the boiler.
The manufacturer declines all responsibility for damage to people, animals and things that may originate from tampering or
incorrect interventions on the boiler.
If the boiler remains inactive for a long time and is electrically disconnected, it may be necessary to unblock the pump.
This operation, which involves disassembling the casing and accessing the inside of the boiler, must be carried out by qualified
personnel.
Blocking of the pump can be avoided if the system water is treated with specific filming products suitable for multi-metal
systems.
