CONTROL PANELS

DIEMATIC-M3 AND K3 CONTROL PANELS

DIEMATIC-m3 control panel

The DIEMATIC-m3 control panel is a very advanced control panel, which includes electronic programmable regulation as standard to modulate the boiler temperature by activating the 2-stage burner according to the outside temperature and, in certain cases, the room temperature, if a CDI D. iSystem or CDR D. iSystem interactive remote control is connected (optional).As standard, DIEMATIC-m3 is capable of automatically operating a central heating installation with a direct circuit without mixing valve or a circuit with mixing valve (the flow sensor – package AD199 – must be ordered separately, however).By connecting another 1 or 2 “PCB + sensor for 1 valve circuit” options (package FM48), it is therefore possible to control up to 3 circuits with mixing valve and each of these circuits can be fitted with a CDI D. iSystem or CDR D. iSystem remote control (optional).Connection of a domestic hot water sensor enables the programming and regulation of a DHW circuit by activating

a control system on the load pump; DHW looping can be handled thanks to the auxiliary contact which includes its own programming.DIEMATIC-m3 also provides antifreeze protection for the installation and the living space if the home is unoccupied and can be programmed 1 year in advance for a period of up to 99 days.Furthermore, the control system includes an “anti-legionella” protection option.Moreover, in the context of larger installations, it is possible to connect from 2 to 10 boilers in cascade: only the first of these boilers will be fitted with the DIEMATIC-m3 control panel, whilst the others will be fitted with the K3 control panel. Each of these DTG… K3 boilers can in turn be complemented with PCBs (AD220 + 1 or 2 x FM48) for controlling up to 3 circuits with mixing valve (see p. 7) with or without CDI D. iSystem or CDR D. iSystem remote control.

The control module integrated into the DIEMATIC-m3 control panel enables the installer to set the parameters for the entire heating installation, whatever its degree of complexity. It can be used to manage equally well:- a DTG… DIEMATIC-m3 boiler installed alone.- or a cascade of boilers in which only the first will be fitted with

the DIEMATIC-m3 control panel, all the others being fitted with the K3 control panel.

It also enables the user to programme each of the circuits in the installation independently, including those connected to the slave boilers with K3 control panel in a cascade installation. It makes it possible to select the appropriate operating mode for heating (Auto mode depending on programming, “Day”, “Night” or “Antifreeze” temperature mode, whether temporary or permanent), and for domestic hot water production (Auto, temporary or permanent forced load). It also makes it possible to access the various settings parameters and measurements in the installation to modify them or simply consult them, etc.

INFORMATIONS REQUIRED FOR INSTALLATION

INSTALLATION IN BOILER ROOMS

VentilationThis must comply with prevailing national regulationsExamples (valid in France):Top and bottom ventilation mandatory- Top ventilation:

Cross section equal to half of the total cross section of the flue gas conduits with a minimum of 2.5 dm2.

- Bottom ventilation: Direct air inlet: S (dm2) 0.86 P

20P = Installed output in kW

The air inlets must be located in such a way in relation to the top ventilation vents that air is renewed in the entire volume of the boiler room.

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.

INSTRUCTIONS FOR HYDRAULIC CONNECTION

EXAMPLES OF INSTALLATIONS

Operating in cascadeAfter stopping the burner:- time delay required before the order to close a gate valve:

3 min.- order to stop the shunt pump (located between the boiler and

the gate valves) using the limit switch contact on the gate valve.

Water flow rate in the boilerThe water flow rate in the boiler when the burner is operating must be between 1/3 of the nominal flow rate and 3 times the nominal flow rate.Nominal flow rate Qn = 0,86 Pn

15Minimum flow rate Qmin = Qn = 0,86 Pn 3 45(this flow rate also corresponds to the minimum shunt flow rate in the boiler)

Maximum flow rate Qmax = 3 x Qn = 0,86 Pn 5Qn in m3/hPn Nominal output (maximum boiler output) in kW

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 prevailing local and national regulations.

NB: 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 these pipes to prevent any corrosion to the connections, if the distribution pipes are made of copper.

- Complies with the requirements of European Directives.- Heating body in Eutectic cast iron, with optimised exchange

surfaces, operating at low inlet temperature modulated down to 40°C with complete cooling between two heating requests. This technological principle considerably reduces stand-by energy consumption.

- The combustion chamber design ensures NOx level < 200 mg/kWh by DTG 330-…S (in compliance with EN 297 PrA2).

- Low noise atmospheric burner. Measured sound power level: Lw(A)< 61 dB(A) in 2nd stage and 53 dB(A) in 1st stage (in compliance with NF D 30.010).

- Total insulation of the heating body and the draught diverter with glass wool (100 mm thick). The glass wool is covered on two sides with a protective fabric, guaranteeing its durability and easy installation.

- The water circuit is rendered leak-tight by spherical nipples which facilitate the installation of the cast iron sections and is resistant to the high operating pressure.

- Burner fitted on a drawer guidance system on rollers, equipped with a gas unit preset for a 2 stage operating with pressostat min. in 20/25 mbar version and pressostat mini./max. in 300 mbar.

- Electrical ignition with ignition burner and flame monitoring with ionisation probe.

- Draught diverter hood with inspection hatch for an easy access to the heating body.

- Water and gas-connection on the rear side with possibility of sealing in the threads.

- Electrical connections easily accessible.- Reversible gas inlet.
