ONTROL Figure 3/6 - HDG Control control unit The boiler control HDG Control unit in the control cabinet is the elec- tronic hub. This is a freely programmable PLC control. Via the control unit, you can adjust the heating system HDG Compact 99 - 200 and obtain information on the current process status.
3.4 Fuel quality requirements ERMISSIBLE FUEL The HDG Compact 99 - 200 heating system is designed for the stan- dard use of burning wood fuel products made from untreated wood in the form of wood chips, shavings and wood pellets.
Wood chips from category 45 can be used as fuel in all HDG HDG Compact 99 - 200 wood chip boilers. For P45 wood chips at least 75% by weight of the wood chips must measure between 8 mm and 45 mm.
The ash content for wood in category 2 is higher than that of cate- SH CONTENT gory A1 due to the higher proportion of bark, needles and leaves. The maximum permissible ash content of wood chips for the HDG Compact 99 - 200 is 1.5 % by weight (A1.5). OOD PELLETS With regard to the quality standards for wood pellets, DIN EN 14961-2 "Solid biofuels - fuel specifications and classes - wood pel-...
The optimal ash content is 1% by weight (A1.0). For HDG Compact 99 - 200 heating systems, it is possible to use wood fuel products of grain size P45 with a maximum water content of up to 30 %.

The following table indicates the maximum nominal thermal value OMINAL THERMAL VALUE depending on water content, in reference to the fuels approved for DEPENDING ON WATER the HDG Compact 99 - 200 in accordance with DIN EN 14961 "Solid CONTENT biofuels - fuel specifications and classes".

ASSAGE THROUGH THE WALL between the heating room and the fuel bunker. Its position depends on the distance and the position of the HDG Compact heating system within the room and the customer's installation diagram. The passage through the wall between the heating room and the fuel bunker should have a width of 70 cm and height of 70 cm in order to allow the assembly of the delivery auger.

The required flue gas values are listed in chapter “3 Mode of ope- ration”, section “3.3 Technical data”. The benefits of the HDG Compact 99 - 200 can only be reaped if all of the factors necessary for good combustion are carefully adjusted.
Page 37
4 Planning and installation – Connections Since the flue temperature may lie below 100 °C when the system is partially loaded, a chimney/flue is required which meets the require- ments of DIN EN 13384-1: 2003-03 “Thermal and fluid dynamic calcu- lation methods”.
Figure 4/7 - Connection to the chimney To compensate for irregularities in the flue draught of the chimney, HDG Bavaria recommends installing an auxiliary air unit in the flue pipe, or even better, in the chimney itself as shown in Figure 4/7 - Connection to the chimney.
For this reason, the HDG Compact 99 - 200 is fitted as standard with power control and automatic ignition. It is, however, highly recommended to use an accumulator even with automatic boiler systems.
Page 40
For these reasons, a return temperature control must be installed for the HDG Compact 99 - 200 heating system. The return temperature control causes the water from the boiler return line to be mixed with the water from the boiler supply line until the minimum return tem- perature has been reached.

The thermal safety device is to be inspected annually by an autho- rised, qualified technician to verify that it is functional. The thermal safety device must be installed according to guidelines from HDG Bavaria. Important! In order to prevent leaks, avoid turning the connections of the sa- fety heat exchanger anticlockwise when installing the thermal sa- fety device.

Allow the heating system to burn out until the combustion air fan switches off. Turn the heating system main switch off. ✓ No operating mode is displayed on the control unit of the HDG Control. ✓ The heating system has been de-energised.
6.5 Calling up information, selecting and mo- difying parameters On the display of the control panel for the HDG Control, you can call up various information as well as select and modify parameters. Due the freely programmable design and the numerous options in heating system combinations, especially in regard to the extraction technology, the number of parameters can vary greatly.
6 Using the heating system – ON/OFF menu ODIFYING THE DUST REMOVAL SETTING The fan for the HDG cyclone dust extractor, if available, can be set to four different operating modes. • 0-Off – In this mode, the fan for the de-dusting function is not available or not in operation.
6 Using the heating system – TIME menu ETTING UNDERPRESSURE CONTROL VALUES In this menu, the settings for fan speed with the HDG cyclone dust extractor and the underpressure value for the underpressure control can be defined. ✎ See “Procedure” in this section.

– The maximum number of possible reverse attempts can be set. • Ignition temperature – If the temperature in the hot combustion chamber exceeds this value, the HDG Control does not switch on the ignition fan for starting the heating system. ✎ See “Procedure” in this section.
The cleaning and maintenance work can also be performed by an au- thorised specialist heating company through a servicing contract. PARE PARTS Only use genuine HDG spare parts. You can obtain HDG replace- ment parts from your specialist heating company. 7.1 Cleaning and maintenance schedule The specified maintenance intervals are guidelines.
When applying lubricants, oils and grease, observe the specifica- tions of the respective manufacturer. The following illustrations of the HDG Compact 150/200 serve to vi- sualise the cleaning and maintenance work. The construction of the HDG Compact 100/105 heating system differs only slightly. The ap- proach to cleaning and maintenance work, however, is identical.
