THE VARIOUS 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 2 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 AD 199 must be ordered separately, however).By connecting another 1 or 2 PCB + sensor for 1 valve circuit options (package FM 48), it is therefore possible to control up to 3 circuits with mixing valve and each of these circuits can be fitted with a CDI 2 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 (AD 220 + 1 or 2 x FM 48) for controlling up to 3 circuits with mixing valve (see p. 7) with or without CDI 2 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 ROOMSVentilation

This 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.

Compliance with prevailing instructions and regulations is mandatory. In all cases, a sectional valve is fitted as close as possible to the boiler. A gas filter must be fitted to the boiler inlet.DTG 230 boilers are delivered preset for operation onH-type natural gases.Propane conversion kits are available as optional equipment (except for DTG 330 S).

The gas supply pressures are:- 20 mbar for natural gas H.- 25 mbar for natural gas L.- 37 mbar for propane.

For operation at 300 mbar, it is necessary:- to order the 300 mbar operation kit for the DTG 230:

package GC 192, see page 12.- to specify it on order so that the boiler is delivered with the

corresponding specific gas line for the DTG 330

This must comply with the national regulations.An insulation transformer (available as an option, see page 12 or 14) is required if the electrical network does not include neutral

or if neutral is not connected to the earth to ensure correct flame detection by ionisation.

The above drawing gives the minimum recommended dimensions to ensure adequate access around the boiler.

Important: heating flows and returns must be located on the same side of the boiler, either on the right or on the left.

Dimensions a and b correspond to the dimensions to be respected to ensure clearance for the assembly tools (simplified JD for 8- to 14-section boilers or JD-TE Plus for all models):

if a = 500 m; b = 1600 mmif a = 1600 mm; b = 500 mm

Furthermore, the other dimensions indicated provide adequate access in the boiler room and allow for the dimensions of the base frame.

INSTALLATION DIAGRAMS

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.
