4 OPERATION

The Avanttia boiler is designed to heat a heating installation and provide domestic hot water, instantly and/or by collection.

Standaring functioning:

The boiler provides both heating and DHW in this mode. The burner and the circulating pump

will switch on and the diverter valve will switch to DHW mode. When the DHW storage tank reaches the DHW setpoint temperature selected, it was ready to warm the heating installation, by putting the diverter valve in heating mode. The burner will shut down when the boiler reaches its selected setpoint temperature. The circulation pump will stop when the room temperature reaches or exceeds the temperature set on the installation’s room thermostat (if it has one).

Functioning according to outdoor temperature conditions

When the boiler is connected to an outdoor temperature sensor (supplied with the boiler), functioning may be activated according to the outdoor temperature conditions, using parameter P.10 on the

"Technical Menu".

When this operating mode is activated, the boiler and/or heating output temperature are determined in accordance with the K curve set (for parameter P.11 of the

"Technical Menu"

for circuit 1 and P.31 for circuit 2) and the outdoor temperature measured. If the installation is correctly dimensioned, the boiler temperature and/or output temperature calculated will ensure the room temperature is in accordance with the set point programmed.

The K curve relates the outdoor temperature reading on the sensor installed outside the home to the boiler temperature setpoint. The graph shows the temperature ratio for each point on the K curve.

IMPORTANT: To connect the outdoor temperature sensor to the boiler, carefully follow the

connection instructions provided in the

"Electrical Connections"

section.

5 ADDITIONAL FUNCTIONS

The Avanttia boiler has the following additional control functions:

5.1 Antilegionella function

Using the P.17 parameter, it is possible to activate the function of protection against Legionella bacterium. With the feature enabled, every 7 days, DHW tank temperature rises up to 65 ºC.

5.2 Pumps anti-block function

This feature prevents the boiler circulation pumps from seizing up if they have been out of use for a long period. This system remains enabled while the boiler is plugged into the mains.

5.3 Anti-frost function

This function protects the boiler from freezing up during cold weather. If the boiler temperature drops to below 6 ºC, the heating circulation pump will start up. If the boiler temperature continues to drop and reaches 4 ºC, the burner will start up, heating the installation. When this function has been activated, it will continue working until the boiler reaches 8 ºC. This system remains on standby while the boiler is plugged into the mains.

5.4 Boiler pressure sensor function

This function prevents boiler failure caused by a low water level and excess pressure in the boiler. The pressure is detected by a pressure sensor, and its value appears on the control panel display (on the

“User Menu”

). If the pressure drops below 0.05 MPa (0.5 bar), the electronic control switches off the boiler and triggers an alarm on the display ("E02"). When the boiler pressure exceeds 0.25 MPa (2.5 bar), an alarm is triggered on the display ("HI") to warn of the excess pressure. If this should occur, we recommend calling the nearest Technical Assistance Service, and draining the boiler until the pressure is between 0.1 and 0.15 MPa (1 and 1.5 bar).

5.5 Resetting to factory default values

If these settings are wrongly adjusted or if the boiler functions incorrectly, all the original settings of all the parameters can be restored by selecting oH in parameter P.26.

5.6 Connecting the LAGO FB OT+ remote control

The boiler has a terminal strip, J5, for connecting the LAGO FB OT+ remote control (see

"Connection Diagram”

). This allows the heating mode for circuit 1 to be switched off, according to

the room temperature. Installing the LAFO FB OT+ remote control enables the heating and DHW system to adapt to the

scheduled times for use of the installation. It also optimises the installation’s functioning, adapting the heating setpoint temperature to the room temperature and improving comfort.

5.7 Room thermostat connection

The boiler has two terminal strips, J4 and J6, for connecting room thermostats or room chronothermostats (TA1 and TA2, see "Electrical Connection Diagram”). This allows the heating mode for each circuit installed to be switched off according to the room temperature. To connect it, remove the bridge joining the terminals of each terminal strip, J4 and J6, and connect room thermostat Nº 1 or Nº 2 for circuits 1 or 2 respectively.

Installing a room thermostat will optimise the performance of the installation, adapting the heating to your home’s requirements and obtaining enhanced comfort. Also, if the thermostat allows the hours of functioning to be programmed (chronothermostat), it can adapt the heating system to the hours of use of the installation.

Avanttia

12

6 FUNCTIONING OF HEATING CIRCUIT 2 (OPTIONAL)

All the boiler models in the Avanttia range may optionally control a second heating circuit. For this second circuit to be controlled, a second circulating pump (BC2) needs to be installed on the boiler if a direct circuit is required, or a pump (BC2) and a mixer valve (M2) if a mixed circuit is required. For correct installation, carefully follow the instructions given in the

“Installation with two heating circuits”

section of this manual.

Direct circuit functioning

Heating circuit 2 will work with the selected boiler setpoint temperature and the temperature of room thermostat 2 (TA2) (if the boiler has one). When circuit 2 is functioning with an external sensor (P.10 = ON and P.31 not OFF), the boiler temperature will depend on the outside temperature and the curve selected in setting P.31.

Mixed circuit functioning

Heating circuit 2 will work with the selected setpoint flow temperature for mixed circuit 2 and the temperature of room thermostat 2 (TA2) (if the boiler has one). When circuit 2 is functioning with an external sensor (P.10 = ON and P.31 not OFF), the setpoint flow temperature will depend on the outside temperature and the curve selected in setting P.31.

In both cases, the burner, the heating pump of circuit 2 (BC2) and the mixer valve (M2) (if the installation has one) will begin to function until the selected temperature is reached in the installation or on room thermostat 2 (if the installation has one). When the temperature of the installation drops below the selected boiler temperature, the burner will start up again, running the heating cycle.

13

7 LAGO FB OT+ REMOTE CONTROL (OPTIONAL)

A remote control (LAGO FB OT+) can optionally be supplied together with the Avanttia boiler. This remote control can be used to fully operate the boiler from anywhere in the room in which it is installed. The LAGO FB OT+ remote control governs the parameters of heating circuit Nº 1 and the installation’s domestic hot water production.

This remote control allows the hours of home comfort to be programmed for heating circuit Nº 1, adjusting the installation to the particular requirements of the home by measuring the room temperature and consequently adapting the installation temperature. The remote control can also be used to adjust the hot water and heating set point temperatures at any time, and for viewing the different boiler operation parameters. It also warns of any functioning anomalies affecting the boiler.

The LAGO FB OT+ remote control may optionally be connected to an external sensor, for measuring the outside temperature. With this option installed, the remote control can adjust the home comfort level (circuit Nº 1) according to the weather conditions at each particular time, optimising fuel consumption and heating comfort in the home.

The LAGO FB OT+ remote control takes over the control of the boiler when it is connected to it. The different selectable boiler temperatures must be modified using the remote control. It is easy to install, only requiring 2 wires for communication between the boiler and the LAGO FB OT+ control. It is connected to the boiler by connecting the two wires on terminal strip J6 (see “Electrical Connection Diagram”). For correct installation and functioning, carefully read the instructions enclosed with the remote control.

The following sections contain a general explanation of the different operating modes and options of the LAGO FB OT+ remote control.

NOTE: The "AF outdoor temperature sensor" indicated in the instructions manual of remote

controller is not compatible with the boiler, so it is compulsory the use of "EVT outdoor sensor" (provided within the boiler) to measure the outdoor temperature.

7.1 Functioning without an outdoor sensor Conventional heating installation (direct circuit)

The maximum temperature for heating circuit Nº 1, the heating times and the desired room temperatures can be selected on the remote control. The LAGO FB OT+ remote control will calculate the boiler temperature required at each particular time, depending on the temperature of the room, and it will activate or disable the heating mode of circuit Nº 1 depending on the heating times and room temperatures programmed.

Instalation of heating circuit Nº 2 (optional)

If the boiler is supplied with an second heating circuit, this circuit is adjusted and controlled via the boiler control panel (see

"Functioning of heating circuit Nº 2 (optional)"

).

Avanttia

14

7.2 Functioning with an external sensor (Optional)

If the LAGO FB OT+ remote control is fitted with an outdoor temperature sensor, it can calculate the heating temperature of heating installation Nº 1 according with the outside weather conditions at each particular time, with optimum adjustment of the heating installation conditions for improved heating comfort in the home and energy savings.

The maximum temperature and an operating curve for heating circuit Nº 1, the heating times and the room temperatures desired can all be selected on the remote control (see instructions enclosed with the LAGO FB OT+ remote control). The LAGO FB OT+ remote control calculates the required boiler temperature at each particular time, depending on the temperature inside the home and the outside weather conditions, in accordance with the operating curve selected (parameter 01 on the

“User Menu"

of the LAGO FB OT+), switching the heating on and off in accordance with the heating

times and the room temperatures programmed. Depending on the type of heating circuit, the following adjustments should be made:

Conventional heating installation (direct circuit)

In setting 01 of the LAGO FB OT+

“User Menu"

, select a curve of at least 1. The maximum boiler

temperature can also be selected on the LAGO FB OT+ remote control.

Installing low temperature heating (mixed circuit)

In setting 01 of the LAGO FB OT+

“User Menu”

, select a curve of less than 0.8. We also recommend selecting a maximum flow temperature NO HIGHER THAN 85ºC, to protect the underfloor heating installation from overheating. To do this, select the maximum flow temperature of heating circuit 1 in setting 07 of the LAGO FB OT+

8 COMMISSIONING OF THE BOILER

The start-up of the boiler, for the validity of warranty to be in force, is to be carried out by an authorised Technical Assistance Service. Prior to proceeding to such a start-up, the following steps

will be performed:

- Check that the boiler is properly connected to the electric power supply.

- Check that the installation is filled with water (the pressure gauge must indicate a pressure between 0.1 and 0.15 MPa (1 and 1.5 bar)).

- Check for the proper chimney installation.

- Check that the gas supply connection is properly installed.

- Drain the air off the boiler gas circuit by opening the shutoff valve of the gas line and loosening lightly the valve gas intake pressure tapping for a moment as, otherwise, the air would be forced to come out slowly through the pilot burner injector.

- Check that the heating circuits outlet and return flow valves are opened, if any.

- Turn the chronothermostat or LAGO FB OT+ remote control (if these are fitted) to the desired setting.

- It is compulsory to do a combustion analysis in the boiler, using a proper tester. The combustion test will be done through the hole for this purpose, placed in the plastic pipe of combustion products exhaustion inside the boiler. If test is out of margins described in the section "Combustion adjustment", it will be necessary to adjust the combustion.

To start up the boiler, hold down the button, select the desired setpoint temperatures and turn the chronothermostat or LAGO FB OT+ remote control (if these are fitted) to the desired setting.

9 BOILER DELIVERY

The Technical Assistance Service, once the commissioning of the boiler has been carried out, will explain the boiler operation to the users by informing them about the most necessary remarks.

The installer will be responsible for explaining to the users the operation of any control or regulation device that is a part of the installation and it is not supplied with the boiler.

10 SHUTTING DOWN THE BOILER

To switch off the boiler, hold down the button. In Off mode, while the boiler is plugged into the mains and connected to the fuel installation, its heating and hot water functions will be switched off

but the anti-frost protection and pump anti-block functions will remain activated. To shut down the boiler functioning completely, unplug it from the mains and cut off the fuel supply.

11 DRAINING THE BOILER

The water is drained from the boiler by opening the air drain valve

(10)

, located inside the boiler on the lower left hand side of the heat exchanger. Connect a flexible tube to this valve and run it to a drain. After draining the boiler, close the valve again and remove the flexible tube.

If any of the safety cut-outs described below should occur repeatedly, switch off the boiler and call your nearest official technical assistance service.

12.1 Temperature safety cut-out

When this cut-out occurs, the "E30" code (temperature alarm) will begin to flash on the digital display and the alarm warning pilot light will flash on the control panel. The burner will switch off and stop heating the installation.

This occurs when the boiler exceeds a temperature of 110 ºC. To unblock it, wait until the boiler drops to below 100 ºC and press the button .

12.2 Burner cut-out

When this cut-out occurs, the code “E09” will begin to flash on the digital display and the flame failure symbol. The burner will switch off and stop heating the installation.

This occurs as a result of an anomaly in the burner or in the fuel installation. To unblock it, press the button

.

12.3 Low pressure cut-out

When this cut-out occurs, the code “E02” will begin to flash on the digital display and the flame failure symbol. The burner amd the boiler circulation pumps will switch off, cutting off the heating and water flow to the installation.

This occurs when the boiler pressure drops to below 0.05 MPa (0.5 bar), preventing the boiler from functioning when the water is drained from the installation, due to either leakage or maintenance

operations. To unlock it, press the button

.

13 BOILER MAINTENANCE

To maintain the boiler in perfect working order, a yearly overhaul is to be performed by DOMUSA TEKNIK’s authorised personnel.

Boiler and flue maintenance

The most important aspects to be checked are as follows:

- The water pressure in the heating installation, when the water is cold, must be between 0.1 and 0.15 MPa (1 and 1.5 bar). If it is not between these values, it must be filled until they are reached.

- The control and safety devices (thermostats, gas valve, etc.) must function correctly.

- The burner and the inside of the boiler chamber must be clean. Soft brushes or compressed air are recommended for cleaning the boiler, to prevent damage. Do not use chemical products.

- The expansion vessel must be full, in accordance with the specifications on the vessel plate.

- Check the gas and water installations are completely sealed.

- The flues must be free of any obstacles and have no leaks.

- The gas flow must remain between the values indicated on the

Specifications Sheet

.

- The circulating pumps and mixer valves (if the boiler is equipped with these) must not be blocked.

Cleaning the boiler

The boiler does not require any special maintenance. Yearly cleaning at the end of the heating season will be sufficient. The boiler chamber and burner should not be cleaned using chemical products or steel brushes. After any cleaning operation has been carried out, it is important to ensure that several ignition cycles are performed to check all the elements are functioning correctly.

After checking the boiler is functioning correctly, ensure there are no leaks.

Draining the condensation water

The boiler condensation water drain outlet should not be altered in any way and it must be kept free of obstructions. Yearly cleaning of the condensation collection siphon is recommended.

If a neutralisation system is installed at the condensation drain outlet, it should undergo periodical maintenance, in accordance with the manufacturer’s instructions.

Cleaning products

Never use chemical products to clean the boiler. A plastic brush is sufficient, if the cleaning is carried out annually.

The cleaning of the boiler and hydraulic circuit will have lasting effects if water with a hardness of over 25ºF is treated previously. For softer water no treatment is required. In any case, a descaling pump should be used to carry out the descaling process.

Anti-frost precautions

The Avanttia boiler, have a function to prevent the installation from freezing, ensuring that the boiler is connected to the electrical power supply. In any case, and mainly in geographical zones where very low temperatures are usual, it is advisable to add anti-freezing liquid to heating circuit. When a very long period the boiler is not going to work, it is advisable to empty the boiler totally.

Boiler water characteristics

In case of water hardness of over 25-30ºF, we recommend using treated water in the heating installation to avoid any scale deposits on the boiler.

Bear in mind that a scale deposit of even a few millimetres will cause a major reduction in boiler performance, as scale is a poor thermal conductor.

It is essential to treat the water used in the heating circuit in the following cases:

- Very long circuits (containing a large amount of water).

- Frequent filling of the installation.

If repeated partial or total draining of the installation is necessary, we recommend filling it with treated water.

14 ALARM CODES

The Avanttia boiler has an electronic circuit which performs continuous self-testing to detect any malfunctioning in the boiler. When the electronic control detects malfunctioning, this is indicated by an alarm code flashing on the display. The following list describes the alarm codes that may appear:
