risks of corrosion due to condensate. The modulating pump fully optimises the boilers yield, precisely adjusting capacity in

order to obtain an optimal temperature difference between delivery and return. Lastly, the wide modulation range of the burner

means that boiler power can be best adapted to the required thermal load. Adjustment of the various generator components

is carried out by a digital PCB with latest generation double microprocessor, resulting in simple and reliable management of

the boiler through a control panel with large LCD. As well as daily and weekly programming of heating and sanitary functions

and the setting of climatic adjustment in accordance with the users criteria of comfort, the electronics system also permits easy

integration with renewable energy heat generation system by programming a series of regulating parameters with which the

generator can be configured to optimise its performance in relation to the type of system it will be working on. Further proof of

the great flexibility of this range of boilers in highly diversified contexts.

6DiagramsThe following diagrams, over and above supplying a better definition of the plan of the system, permit a more detailed analysis of how the generator behaves under different working conditions.The pump capacity-prevalence curve defines the dynamic characteristics of the BAXI circulator in the hydraulic unit. It is well known that the temperature of the return water has a direct influence on the performance of a condensation boiler. At very low temperatures there is better exploitation of the latent heat and consequently better boiler performance. The diagram shows the variations in performance as a ratio between the capacity and thermal power of the specified condensation generator in function of the boilers return temperature. The final diagram shows the trend of the generator flue temperature in function of the return temperature.

Burner-exchanger unitThe air-gas premixing unit, the burner and the primary exchanger are the components that ensure high performances from these

condensing heat generators.

The premixing unit is a new conception which, thanks to a new design and the double clapet technique, ensures that the burner

constantly has an optimal air/gas ratio independently from the number of fan revs, keeping consumption to a minimum and

always guaranteeing correct combustion and consequently a reduction in polluting emissions. On the same subject of energy

saving and highest performances, this new component permits achievement of a modulation ratio of 1:9, giving the generator

such great flexibility as to be adaptable to great variations in thermal load, as happens increasingly in new generation multifamily

homes.

In the range from 35 to 70 kW the stainless steel burner, through the internal diffuser and special micro-perforation on the

cylindrical surface, achieves uniform distribution of the air/gas mixture independently of its length. In the power range of 90 to

110 kW the burner is in metal fibre. This produces a spread of very short flame for optimal heat radiation while minimising the

formation of nitrogen oxides.

In the range from 35 to 70 kW the primary exchanger, entirely in stainless steel, comprises one single burner/fumes chamber,

which keeps the size of the generator down for high power and actually more versatile installations even in relatively restricted

spaces. The two highest powered generators (90 and 110 kW) employ the dual chamber exchanger in stainless steel. The two

cylindrical fumes chambers set vertically (burner chamber and condensation chamber) contain the stainless steel coils that carry

the primary circuit water. In the upper chamber the hot exhaust gases transfer heat to the system return water in the coils,

bringing about condensation of the fumes themselves and thus transferring the latent heat to the water, preheating it prior to its

entry into the burner chamber.

Boiler functioning information Off, Reset, Exit menu/functions

The whole range of LUNA DUO-TEC MP high power wall-mounted boilers are equipped with an extensive control panel: each key activates a specific function and the LCD simultaneously shows numbers and symbols indicating the functioning status, facili-tating easy interpretation and immediate programming, adjustment and control of parameters.

The boiler electronic PCB has been specially designed to run premixing condensation boilers and permits start-up, control and supervision of this kind of gas fired heat generator with view to obtaining best use of the burner for applications in the field of central heating and the generation of hot sanitary water. Indubitably the most important feature of this new generation of electronic boards is its ability to integrate different heat gen-eration technologies through the use of small interface boards and by means of a communication protocol that allows dialogue among the various parts of the heating system.

All the control, management and communications software (meaning the whole intelligent part of a heating system) resides in the boiler PCB, so the only interfaces needed for integration with other types of generator are hardware items such as extensions of connectors on the motherboard and, where required, an additional display (text knob) for the parameter programming of a complex heating system.

Features: double microprocessor: latest generation software for control of the generator, or also of a complete heating system. management of primary circuit pump modulation by PWM controller daily heating programme and generation of hot sanitary water electronic thermometer automatic troubleshooting: signalling and description of possible anomalies incorporated climatic regulation (external probe available as optional) automatic summer/winter changeover with external probe connected preset for installation in cascade with control software included in the PCB preset for installation in mixing systems (low and high temperature)

Connection of clip-in module THINK

With clip-in module THINK the heater can manage either a mixing zone, controlling the mixing valve, zone sensor and pump, or a solar system by means of the sensors on the collector, tank and solar pump. This accessory is installed in the boiler dashboard. You must remove cover A from dashboard B. Raise dashboard B and hook up the flat cable between connector X50 of clip-in module and connector X41 of the boiler board, passing through the hole in dashboard B. Close dashboard B and insert the clip-in module. Carry out the electrical hook-ups necessary for installation and fix the new cover C found in the pack.

Connection of external module THINK

External module THINK is a device which, in a heating system run with LUNA DUO-TEC MP boilers, supplies several programmable inlets/outlets necessary to complete the heating system.As for individual installations, the module external module can supply the boiler with the inlets/outlets necessary for management of a mixing zone or, alternatively, a solar system.The accessory is connected to the cascade of LUNA DUO-TEC MP boilers by means of a local bus through which the information regarding the devices connected is received and transmitted.

For each individual boiler a maximum of three extension modules can be installed, one clip-in module and two external module for the management of a maximum of three mixing zones.When it is used for management of mixing zones the external module requires the presence of a remote control (see relevant section on page 20) for programming the zone control parameters. In this case the remote control may also be used as a room sensor for the mixing zone.

The external module may also be used to manage solar system by means of the boiler. In this case the connections supplied by the module are the two inlets related to the sensor on the collectors and to the sensor on the tank, whereas the outlet regards control of the solar pump (see figure).

In the case of a mixing zone, hook up the safety thermostat between the FX23-L terminals and jump the terminals EX21-FX23. In this way the circuit pump connected to relay QX23 is internally connected in series with the safety thermostat.

Should it be necessary to use relay outlet QX23 for functions other than those envisaged for the mixing zone, jump terminals FX23-L.

Some easy schemes to enter the THINK world

Heating circuit with 2 high temperature zones, one zone controlled with a thermostat and one zone controlled with THINK remote control.

1) How many independent zones are in the system?

There are 2 independent zones, so the 2 heating zones HC1 and HC2 must be activated. This means to set the 2 registers:

5710 zone HC1 On (factory set)5715 zone HC2 On

2) The valve of HC1 zone is controlled by the boiler PCB, it means the relevant parameter of the QX1 terminal to which the valve is connected has to be set and it must be fixed that is the pump (or the valve) of HC1 zone

5890 OUTPUT QX1 pump of the circuit HC1 (factory set)

3) The thermostat of the high temperature zone HC2 is connected to RT terminal of the boiler (input H5). It has to be set the thermostat connected to the relay is the zone HC2 one.

5977 INPUT H5 RT of the circuit HC2

4) Then it has to be set the remote control that is the address 1 and it is assigned to the zone HC1, it means:

40 (of the remote control) use Room Unit 142 (of the remote control) assignation zone HC1 To invert the 2 zones and make 1 the zone HC2 and 2 the zone HC1, without switching the connections, it would be enough to change the setting of the parameter 5890

5890 OUTPUT QX1 pump of the circuit HC2

then to set the release to the valve as the release to valve of the zone HC2, change the parameter 5977

5977 INPUT H5 RT of the circuit HC1

Example scheme of heating circuit with 2 high temperature zones

HC1HC2

29


to set on the PCB of the boiler that the RT is the zone HC1 thermostat and to change the parameters of the remote control:

40 (of the remote control) use Unit Ambiente 142 (of the remote control) assignation Multi-function

Example scheme of heating circuit with 3 high temperature zones

Heating circuit with 3 high temperature zones, one zone controlled with a thermostat and two zones controlled with THINK remote controls.An external programmable module has been installed to in increase the number of the connections of the PCB and to control the 3 zone valves.

1) How many independent zones are in the system?

There are 3 independent zones, so the 3 heating zones HC1, HC2 and HC3 must be activated. This means to set the 3 registers:

5710 zone CR1 On (factory set)5715 zone CR2 On5721 zone CR3 On

2) An external programmable module THINK has been used, so this accessory has to be set by the activation on the register 6020:

6020 FUNCTION EM1 Multi-functionThis setting defines the external module with the address 1 (EM1) as multi-functional.

3) The valves of the 3 zones HC1, HC2 and HC3 are controlled by the external programmable module, so the relevant parameters of the external module have to be set to define which terminals of the external module control the valves (in this contest pump and valve have the same meaning)

6030 OUTPUT QX21 EM Pump of the circuit CR1 6031 OUTPUT QX22 EM Pump of the circuit CR26032 OUTPUT QX23 EM Pump of the circuit CR3

4) The thermostat of the high temperature zone HC3 is connected to the terminal RT of the external module (input H2). It has to be set that the thermostat connected to that terminal is the one of the zone HC3

6046 INPUT H2 EM1 RT of the circuit HO3

HC1HC2HC3

30

5) Then the remote controls of the zone HC1 and HC2 have to be linked to the relevant zones, it means

40 (of the remote control address 1) use Room Unit 142 (of the remote control address 1) assignation Zone HC1

40 (of the remote control address 2) use Room Unit 2In this case it is not necessary to give the assignation, because it is automatically set in those units where the use is different form Room Unit 1.

Example scheme with 2 low temperature zones and 1 high temperature zone

Heating circuit with 2 zones low temperature controlled by remote controls THINK and 1 zone with high temperature controlled by room thermostat.

To control low temperature zones it is ALWAYS necessary to use a programmable module (clip-in or external module). In this case, 2 modules are necessary.

First of all, the 3 heating zones HC1, HC2 and HC3 have to be activated. This means to set the 3 registers:

5710 zone HC1 On (factory set)5715 zone HC2 On5721 zone HC3 On 2 programmable modules have been used, so they must be qualified by means of the activation on the register 6020 and 6021:

6020 FUNCTION EM1 Zone HC16021 FUNCTION EM2 Zone HC2

These settings assign the external module with address 1 (EM1) to the zone HC1 and assign the external module with address 2 (EM2) to the zone HC2.

Since the safety thermostats of the low temperature zones are both connected to the terminal EX21 of the relevant external modules, this choice has to be to be set:

6024 Terminal EX21 of EM1 Safety thermostat zone HC16026 Terminal EX21 of EM2 Safety thermostat zone HC2

The thermostat of the high temperature zone HC3 is linked to the terminal RT of the PCB of the boiler (H5). It must be defined that the thermostat connected to this terminal is the thermostat of the zone HC3

Ext. module THINK

Ext. module THINK

HC1HC2HC3

31


6046 INPUT H3 RT of circuit HC3

Also the valve of the zone HC3 is connected to the programmable output QX1 of the PCB of the boiler. So it is necessary to set the following parameter:

5890 OUTPUT QX1 Pump of the circuit HC3

Then the remote controls of the zone HC1 and HC2 have to be linked to the relevant zones, it means

40 (of the remote control address 1) use Room Unit 142 (of the remote control address 1) assignation Zone HC1

40 (of the remote control address 2) use Room Unit 2In this case it is not necessary to give the assignation, because it is automatically set in those units where the use is different form Room Unit 1.

Example scheme of heating circuit with 1 high temperature zone, 1 low temperature zone and a solar tank for DHW production with solar integration

Heating circuit with 2 zones, 1 with high temperature and 1 with low temperature controlled by room thermostat, with a solar system

To control low temperature zones it is ALWAYS necessary to use a programmable module (clip-in or external module). Also to control a solar system it is necessary to employ an external programmable module. In this case, then, 2 modules are necessary.

First of all, as we have seen, the 2 zones HC1 and HC2 have to be activated. This means to set the 2 registers:

5710 zone HC1 On (factory set)5715 zone HC2 On

2 programmable modules have been used, so they must be qualified by means of the activation on the register 6020 and 6021:

6020 FUNCTION EM1 Zone HC16021 FUNCTION EM2 Solar system for DHW production

Ext. module THINK

Ext. module THINK

32

These settings assign the external module with address 1 (EM1) to the zone HC1 and assign the external module with address 2 (EM2) to the control of the solar collectors. Obviously the sensors and the pump of the solar system have to be connected to the relevant terminals, specified in the technical manual of the external programmable module:

BX22 Solar sensor tank side

BX21 Solar sensor collectors side (Pt 1000)

QX23 Solar pump circuit

Since the low temperature safety thermostat is linked to EX21 terminal of the external module EM1, this choice has to be set on the relevant register:

6024 Terminal EX21 di EM1 Safety thermostat zone HC1

The thermostat of the low temperature zone HC1 is connected to the terminal of the external module EM1 (H2), while the thermostat of the high temperature zone HC2 is linked to the terminal RT of the PCB of the boiler (H5). It must be defined that the thermostat connected to this terminal is the thermostat of the zone HC2

6046 INPUT H2 EM1 RT of circuit HC15977 INPUT H5 RT of circuit HC2

Finally, also the valve of the zone HC2 is connected to the programmable output QX1 of the PCB of the boiler. So it is necessary to set the following parameter:

5890 OUTPUT QX1 Pump of the circuit HC2

System with high power condensing boiler Luna Duo-tec MP 1 direct high temperature circuit 1 low temperature mixing circuit 1 DHW tank with solar integration

This system could be a small multi-familiar building (4-6 flats), where every flat is supplied with low temperature zones with integration (for example in the bathrooms) of high temperature elements.This system could also be one single premise (commercial building, sport center or factory) with underfloor heating system and high temperature integration.In both cases, the DHW is delivered to the users from a central tank whose thermal load is provided with a solar collectors system, eventually integrated with the centralized boiler.

Also for this system, it is necessary to use a programmable clip-in module THINK to control the hydraulic circuit of the solar collectors. Moreover, a programmable external module THINK is required to control the low temperature zone.

In the picture are showed the connections to be done on the programmable clip-in module

System with high output condensing boiler Luna Duo-tec MP 2 low temperature mixing circuits 1 DHW tank with solar integration for heating and DHW production

This system could be a quite big house, with at least 2 zones (ground/first floor) with independent climatic regulation.This system could also be one single premise (commercial building, sport center or factory) with underfloor heating system and high temperature integration.In both cases, the DHW is delivered to the users from a central tank whose thermal load is provided with a solar collectors system, eventually integrated with the centralized boiler.

Also for this system, it is necessary to use a programmable clip-in module THINK to control the hydraulic circuit of the solar collectors. Moreover, 2 programmable external modules THINK are required to control the low temperature zone.

In the picture are showed the connections to be done on the programmable clip-in modules

A Tank sensor (supplied as accessory)

B Solar collector sensor (supplied as accessory)


A Delivery sensor C Mixing zone pump

B Mixing valve D Safety thermostat

In the following parameters, the heating circuit 1 (HC1) is the low temperature zone, while the heating circuit 2 (HC2) is the other low temperature circuit.

Connection of the interface bus for boilers in cascade THINK

The interface bus is an electronic device enabling communication with and therefore the management of boilers in cascade. Thus used, the communication bus also permits remote monitoring and management of the cascade. The interface bus slot is inside the control panel of each boiler in the cascade. There are two possible positions of the accessory inside the panel:

1- If the clip-in module THINK has not already been installed in the boiler, then remove the protective cover on the back of the command panel on the boiler, place the interface bus in the relative slot and, once the electronic circuit of the boiler has been turned on, connect the interface using the cable provided to the connector of the electronic circuit X30.

2- If the clip-in module THINK has already been installed in the boiler, then access the electronic circuit by removing the protective cover on the panel and slot in the interface bus as illustrated below making sure to connect the cable provided to the connector of the electronic circuit X30.

Connection of external module THINKExternal module THINK is a device which, in a heating system run with LUNA DUO-TEC MP boilers, supplies several programmable inlets/outlets necessary to complete the heating system.As for cascade systems, the external module THINK allows connection of a cascade pump (output side) downstream of the hydraulic separator, a loading pump for hot sanitary water storage and, where required, a room thermostat and sensors for flow (usually downstream of the hydraulic separator) and for return (usually upstream) of the cascade. The external module THINK can also supply another programmable outlet at 230V for system necessities.The accessory is connected to the cascade of LUNA DUO-TEC MP boilers by means of a local bus through which the information regarding the devices connected is received and transmitted.

Programming of parameters regarding the cascade of boilers is carried out by means of the remote control to be installed externally (see remote control kit on page 20).

Connection of external module THINK

External module THINK is a device which, in a heating system run with LUNA DUO-TEC MP boilers, supplies several programmable inlets/outlets necessary to complete the heating system.As for individual installations, the module external module can supply the boiler with the inlets/outlets necessary for management of a mixing zone or, alternatively, a solar system.The accessory is connected to the cascade of LUNA DUO-TEC MP boilers by means of a local bus through which the information regarding the devices connected is received and transmitted.

For each individual boiler a maximum of three extension modules can be installed, one clip-in module and two external module for the management of a maximum of three mixing zones.When it is used for management of mixing zones the external module requires the presence of a remote control (see relevant section on page 20) for programming the zone control parameters. In this case the remote control may also be used as a room sensor for the mixing zone.

The external module may also be used to manage solar system by means of the boiler. In this case the connections supplied by the module are the two inlets related to the sensor on the collectors and to the sensor on the tank, whereas the outlet regards control of the solar pump (see figure).

System with two high output condensing boilers Luna Duo-tec MP in cascade 1 high temperature direct circuit 1 DHW tank

This system is similar to the Luna Duo-tec MP single installation already seen, with the difference of the cascade. The example is useful to see the different uses of the electronic devices in presence of a cascade installation.For complete management of the cascade it has to be installed a interface bus kit for boilers in cascade THINK (one in each boiler in cascade), an external module THINK and a remote control THINK for programming all system parameters.The figure shows the connection of the bus modules and the external module.

The connections of external module THINK are highlighted in the figure.
