2 Luna Platinum Luna Platinum range of wall-mounted boilers is composed of heating-only condensing boilers with an output from 12 to 32 kw (at 80 / ). The range stands out for its high performance, ease of use and installation and wide range of accessories for single installation or in cascade. The core element of these condensing boilers is the heat exchanger in stainless steel AISI 316L. The low water content of the exchanger allows for very limited heat inertia and therefore a rapid response to variations in heat demand on the system. The steel surfaces protect the exchanger from the risk of corrosion caused by condensation aximum heating heat input kw 12,4 17,4 24,7 33 aximum heating heat output 80/ kw 12 16, aximum heating heat output 50/30 kw 13,1 18,4 26,1 34,9 inimum heat output 80/ kw 2 2,9 4 5,3 inimum heat output 50/30 kw 2,2 3,2 4,3 5,8 Energetic efficiency 92/42/EE HHHH HHHH HHHH HHHH Average efficiency (DI4702-T8) % 109,8 109,8 109,8 109,8 ominal efficiency 80/ % 97,8 97,7 97,6 97,6 ominal efficiency 50/30 % 105,8 105,8 105,7 105,7 Efficiency at 30% % 107,8 107,7 107,6 107,6 inimum flow on the exchanger lt/h ox class (E483) inimum working temperature Expansion vessel capacity/pre.charge lt 8/0,8 8/0,8 8/0,8 10/0,8 Quantity of condensing l/h 1,5 2,2 2,9 4 Regulation of water temperature in heating circuit bar DHW temperature regulation bar Heating system max pressure bar oaxial flue system max length ø / Dual flue system max lenght ø 80 m m aximum flue mass flow rate kg/s 0,006 0, ,016 inimum flue mass flow rate kg/s 0,001 0,001 0,002 0,003 aximum flue temperature Residual flue prevalence m³/h 16,8 23,5 33,4 44,6 omburent air-flow at Qn Pa Dimensions (h x w x d) mm 7x450x345 et weight kg 34,5 34,5 34,5 37,5 Gas type atural Gas/LPG atural Gas/LPG atural Gas/LPG atural Gas/LPG Power consumption W Power consumption in stand-by way W oise (1 mt far from the boiler) dba <45db (A) <45db (A) <45db (A) <45db (A) Grade of protection IPX5D IPX5D IPX5D IPX5D 82

3 The various parts of the generator are controlled by a latest generation electronics circuit board which makes for simple, reliable boiler management using the extractable control panel with wide LD display. Daily and weekly programming of heating and DHW functions is possible, as is climatic setting according to the comfort criteria chosen by the user and the visualisation of error messages relating to any faults. In addition, such boiler electronics allow technicians to access a series of adjustment parameters and configure the generator so as to optimise efficiency depending on the type of system used.

4 Diagrams As well as illustrating the heating system layout the figures below enable more detailed analysis of generator behaviour in various conditions of use. The pump flow rate-head curve defines the dynamic characteristics of the BAXI circulator inside the hydraulic group. As is known, the temperature of the return water directly influences the efficiency of condensing boilers: at very low temperatures there is better use of the latent heat and consequently improved boiler efficiency. The graph below shows the variations in efficiency, as the ratio of the flow rate to the heat output of the condensing generator specified, depending on the return temperature of the boiler. The last figure shows the trend of the flue temperature of the generator depending on the return temperature.

9 Dual flue system installation This type of pipe permits discharge of the combustion products both outside the building and in single flues. The air intake for combustion may be placed in a different area from that of the discharge. The gaskets and screws of the previously removed from the stopper should be used for air intake connector. The 90 bend enables connection of the boiler to the flues and intake pipes in any direction thanks to the fact that they can rotate by 3. It can also be used as an additional bend in combination with the pipe or 45 bend. (A-B) For special installations of the flues inlet/outlet ducts (B), the orienting dual flue system supplied as an accessory, can be used.

18 onnection of the interface bus for boilers in cascade (OI345) The interface bus OI345 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 extension module AGU2.550 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 OI345 interface in the relative slot and, once the boiler 's electronic circuit has been turned on, connect the interface using the cable provided to the connector of the electronic circuit X30. LPB BUS OI 345 X30 2- If the extension module AGU2.550 has already been installed in the boiler then access the electronic circuit by removing the protective cover on the panel and slot in the OI345 interface as illustrated below making sure to connect the cable provided to the connector of the electronic circuit X30.

19 onnection of extension module AGU2.550 With extension module AGU2.550 the heater can manage either a mixed zone, controlling the mixer valve, zone probe and pump, or a solar plant by means of the probes on the manifold, heater 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 accessory AGU2.550 and connector X41 of the boiler board, passing through the hole in dashboard B. lose dashboard B and insert the AGU arry out the electrical hook-ups necessary for installation and fix the new cover found in the pack. 99

20 1 onnection of expansion module AVS75 Expansion module AVS75 is a device which, in a heating system run with LUA PLATIU boilers, supplies several programmable inlets/outlets necessary to complete the heating system. As for individual installations, the module AVS75 can supply the boiler with the inlets/outlets necessary for management of a mixed zone or, alternatively, a solar plant. The accessory is connected to the cascade of LUA PLATIU 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 expansion modules can be installed, one of which is the accessory AGU2.550 and the other two AVS75 for the management of a maximum of three mixed zones.

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 mixed zone, jump terminals FX23-L. The AVS75 may also be used to manage solar plant by means of the boiler. In this case the connections supplied by the expansion module (AVS75) are the two inlets related to the probe on the manifolds and to the probe on the heater, whereas the outlet regards control of the solar pump (see figure).

21 O 1 2 onnection of expansion module AVS75 As for cascade systems, the module AVS75 allows connection of a cascade pump (output side) downstream of the hydraulic separator, a loading pump for hot sanitary water storage and, where required, an ambiance thermostat and probes for delivery (usually downstream of the hydraulic separator) and for return (usually upstream) of the cascade. The AVS75 can also supply another programmable outlet at 230V for plant necessities.

The pumps of the high temperature zone have to be connected one to each other, and through a relè, linked to the terminal of module AVS75 identified with QX21-. Parameter configuration on non-asters boiler Having configured he master boiler parameters as described in the previous paragraph, proceed to configuration of the other boilers. To this purpose, connect the Remote ontrol (if not already present) to the boiler to be configured and proceed as follows. The operations listed below are repeated for each boiler in the cascade, excluding the ASTER boiler. For correct system functioning an address must be assigned to each boiler so that it can be recognised by the master boiler (the master boiler has default =1). oreover it is also necessary to synchronise the boiler clocks with that of the master boiler.
