5 CONTROL PANEL The DIEMATIC control panel is a very advanced control panel, which includes electronic programmable regulation to modulate the boiler temperature by activating the burner according to the outside temperature and also to the room temperature, if a CDI 2 or CDR 2 interactive remote control (optional) is connected (see page 6). DIEMATIC control panel is capable of automatically operating a central heating installation with a direct circuit without mixing valve (which can even be configured as a swimming pool circuit). Connection of a domestic hot water sensor enables the programming and regulation of a DHW circuit by activating a control unit on the load pump; DHW circulation loop can be handled thanks to an auxiliary contact which includes its own programming. The addition of 1 or 2 PC + sensor for a valve circuit options (package FM 8) enables the regulation of 1 or 2 circuits with mixing Note: the connection terminal block on the DIEMATIC control panel is fitted with a 0- V inlet thanks to which it is possible to control the boiler using an external system which includes a 0- V outlet with set temperature value. valve: a CDI 2, CDR 2 or a simplified remote control for each of these circuits can also be delivered as optional equipment. The connection of other additional circuits is also possible using DIEMATIC VM control units. DIEMATIC control panel also provides antifreeze protection for the heating system water if the owner is absent (absence programmable up to 1 year in advance for a period of up to days). Moreover, in larger installations, it is possible to connect up to boilers C Eco or 5 boilers C 6 Eco in cascade with the DIEMATIC control panel, each boiler can be equiped with 1 or 2 PC + sensors for 1 valve circuit options: to do so, simply connect them to each other using a US cable. Particular case: C 6- Eco The C 6- Eco is fitted with 2 DIEMATIC control panels allowing the 2 boilers which it comprises to operate in cascade. These 2 panels are connected to each other by a US cable and the cascade flow sensor connected to the boiler chosen as the slave, the other boiler being the master.

10 INFORMATION REQUIRED FOR INSTALLATION Minimum door (T) and corridor (K) widths necessary for clearance of the boiler (these are minimum calculated values) K K = T x L and Example: Calculation of the min. width of a corridor (K) necessary for the clearance of a C -50 boiler through a door width T = 00 mm K = x mm minimum T = In order to avoid damage to boilers, it is necessary to prevent the contamination of combustion air by chloride and/or fluoride compounds, which are particularly corrosive. These compounds are present, for example, in aerosol spray cans, paints, solvents, cleaning products, washing powders/liquids, detergents, glues, snow clearing salts, etc. It is therefore necessary: - To avoid sucking in air discharged from premises using such products: hairdressers, dry cleaners, industrial premises (solvents), premises containing refrigeration systems (risk of leaking refrigeration fluid), etc. - To avoid the storage of such products close to boilers. Please note that, if the boiler and/or its peripherals become corroded by chloride and/or fluoride compounds, our contractual warranty cannot be invoked. K x L L oiler room ventilation The cross-section of the boiler room ventilation (through which combustive air is taken in) must comply with the prevailing standard. T 150 GAS CONNECTION Compliance with prevailing instructions and regulations is mandatory. In all cases, a sectional valve is fitted as close as possible to the boiler. A filter should be fitted to the gas supply inlet immediately after the sectional valve. The pipe diameters must be defined in accordance with prevailing specifications. Gas supply pressure: - 20 mbar on natural gas H - 00 mbar on natural gas H with pressure regulator, available as optional equipment (see page ). ELECTRICAL CONNECTION This must comply with the prevailing standard. The boiler is protected by a A circuit breaker located behind the control panel. It must be powered by an electrical circuit comprising a omnipole switch with an opening distance > mm. Notes: - The sensor cables must be separated from the 20 V circuits by at least cm. - In order to protect the pump antifreeze and cleaning functions, we recommend not switching off the boiler at the mains switch.

11 INFORMATION REQUIRED FOR INSTALLATION HYDRAULIC CONNECTIONS Important: The principle of a condensation boiler is to recycle the energy contained in the water vapour in the combustion gases (latent vaporisation heat). Consequently, to achieve an annual operating efficiency in the order of %, it is necessary Connection to the heating circuit C /6-.. Eco boilers must only be used in closed circuit heating installations. The central heating systems must be cleaned to eliminate the debris (copper, strands, brazing flux) linked to the installation of the system and deposits that can cause malfunctions (noise in the system, chemical reaction between metals). More particularly, if fitting a boiler to an existing installation, it is strongly recommended that you clear sludge out of the system before installing the new boiler. After carrying out this work, particular monitoring of the installation may be necessary both in respect of the water in the network and the quality of the water used for topping it up in order to be in full control of the consequences. Suitable filters may be necessary in some cases. Requirements on heating water: - Total hardness: TH < 25 F - Mains ph: PH < Water treatment If the installation requires water treatment: consult us, particularly for: - water treatment which complies with the use of materials used in the construction of the boiler, the aluminium heating body, the ph of the water must not exceed. - the precautions to be taken to prevent the formation and localisation of oxygen in the water in the installation. - antifreeze products: ensure that these are compatible with aluminium and, if need be, with other components in the installation. Maximum/minimum water flow The maximum difference in temperature between flow water and return water, and the speed at which the flow temperature to size the heating surfaces in such a way as to obtain low return temperatures, below the dew point (e.g. underfloor heating, low temperature radiators, etc.) during the entire heating period. increases, are restricted by the boiler s microprocessor (ΔT = 5C); consequently, the boiler does not need a minimum flowrate provided that it operates at a maximum temperature of 5 C. If the maximum temperature exceeds 5 C, it is necessary to respect the following minimum flowrates: Minimum water flowrate: For the C -280 Eco Qmini =.0 m /h For the C -50 Eco Qmini = 5.0 m /h For the C -0 Eco Qmini = 6.1 m /h For the C -500 Eco Qmini =.1 m /h For the C -50 Eco Qmini = 8.2 m /h For the C 6 Eco, the minimum flowrate on each boiler will be equivalent to the minimum flowrate of a C Eco For the C 6-00 Eco Qmini = m /h For the C Eco Qmini = 12.2 m /h For the C 6-00 Eco Qmini = 1.2 m /h For the C 6-1 Eco Qmini = 16. m /h Maximum water flowrate: flow speeds in the heating body which are too high reduce the transfer of heat. Therefore, it is necessary to restrict the water flow to the value obtained using the following formula: Qmax (m /h) = Nominal useful output /. Condensates discharge It must be connected to the waste water discharge system. The connection must be removable and the flow of condensates visible. The connections and pipes must be in corrosion-resistant material. Condensates neutralisation stations are available as optional equipment (see page 8). 11

12 TS N L TS N L C C C C C C INFORMATION REQUIRED FOR INSTALLATION INSTALLATION DIAGRAMS The examples presented below cannot cover the full range of installation scenarios which may be encountered. Their purpose is to draw the attention to the basic rules to be followed. A certain number of control and safety devices are represented but, in the last resort, it is up to the experts, consultant engineers and design departments to make the final decision on the control and safety devices to be used in the boiler room, depending on its specificities. In all events, it is necessary to abide by the codes of practice and the local and national regulations in force. N : For the connection of domestic hot water, a sleeve made of steel, cast iron or any other insulating material must be interposed between the hot water outlet and this pipework to prevent any corrosion to the spot welds, if the distribution pipework is made of copper.
