After filling the system to more than 0.5 bar, the appliance automatically restarts and the fault message disappears. If air enters the appliance when refilling the system, the appliance can switch off with the fault message "F.75". Cause: When starting up the heating pump, the water pressure sensor checks whether the water pressure rises (pressure drop recognition). If air is found in the heating pump, the required pressure increase does not occur and the fault switch-off "F.75" occurs after five attempts. Remedy: Run the purging program "P.00" to fill the appliance return.

4.3.2 Integral condensation heat exchanger

Section of the heat exchanger (image source: AIC) Perforated plate of a 120 KW appliance The entire heat exchanger, including all the fixtures, is made of stainless steel. The upper section of the heat exchanger, above the perforated plate, is the combustion chamber and this section is called the "heating value level", because only a low level of condensation forms here.

The lower section, below the perforated plate, contains oval-shaped pipes (147 pipes for 120 kW, 126 pipes for 100 kW, 91 pipes for 80 kW) with selective narrowing points through which the hot gas flows. Most of the condensation occurs here and it is there-fore called the "calorific value level". The flue gas that is to be cooled uses the guide plate (and the pump) to heat up the pipes to which the water in the heat exchanger flows from below in a meandering pattern to the interior, as shown in the drawing. The heat is then transferred in the counterflow principle and is therefore optimally trans-ferred. Any condensate that forms is caught in the condensate pan at the bottom and is guided to the condensate siphon in the centre. The upper section (combustion chamber) now holds the heated water, which passes to the heating distribution as flow water.

Heat exchanger of a 120 kW appliance, from above 4.3.2.1 Flue gas collector The flue gas collector surrounds the entire heat exchanger and is constructed from stainless steel up to the flue pipe connection. On the one hand, this is used as a con-densate collector and, on the other hand, it is used as a connection to the inner flue pipe. The air/flue gas duct is first connected to the unit's connection adapter.

4.6 Electronics design 4.6.1 General The electronics on the appliance PCB can be used to implement all control and regula-tion functions on the appliance variants. The appliance state is permanently monitored, appliance faults analysed and shown on the display along with the appliance status and fault information. Important data is saved. The electronic controller, the power supply, the fan control and the fan housing are housed in the electronic PCB. The appliances do not have a separate supply trans-former. The task of the transformer is carried out by a switching power supply integrat-ed into the PCB. The ignition transformer is fitted externally in the upper left-hand cor-ner of the appliance. 4.6.2 New! ecoTEC plus PCB
