of wood rises, output is lower than demanded and the service life of boiler as well as that of flue is
shortened. If the draft is as specified, the boiler works up to 70% of output even without a fan.
Electromechanical boiler regulation
Boiler regulation is executed by the boiler thermostat on the boiler panel, by which is the ventilator
controlled according to the set output temperature of the water.
The required boiler operation temperature should be set on the boiler thermostat. On the panel there
is also the flue gas thermostat, which serves for ventilator shut down shut after burning out of fuel.
At heating up it should be set to tehe position of „0°C". After adequate burning up, set the flue gas
thermostat to the operation temperature - the fan has run and it has to shut down only after burning
out of fuel. It is possible to observe the optimum position of thermostat according to the sort of the
used fuel, chimney draught and another conditions. Watch the output water temperature on the
temperature scale of the thermanometer. The irreversible safety thermostat is also located on the
panel (version STANDARD and LAMBDA).
Refueling
For refueling open slowly the feeding door. The heating up flap will be thereby also opened. Do not
turn off the ventilator. During heating keep the feed hopper always full. To prevent smoke escape
into the boiler-room, stoke other fuel only after the original charge is burnt out at least to 1/3 of the
feeding content. Then cover live coal with a broad log and fill in as usually. The fuel must not be
pressed over the jet as this could cause the jet stuck and the boiler parameters would go wrong.
Technical description of ATTACK DPX PROFI:
During the operation, the display is showing the current temperature of outlet heating water.
Rotations of the fan are controlled in the following way:
- if during burning up process the boiler temperature is lower than 45 °C, the fan works with the
output set up by the turning of burning up button situated in rear side of regulator in the range of 40
- 100 %. (you can see it on the display, from r4 = 40% to r9 = 90 %, rF=100%), for boiler
temperature higher than 45°C, the fan works up to 100%.
- if the temperature of heating water during the operation is more than 10°C lower than the one set
up by the turning button, the fan works in 100 % output.
- if the temperature of heating water is lower than 10°C from the temperature set up by the
turning button of the boiler thermostat, the regulator decreases the output of ventilator according to
the difference between these temperatures but only to the output not lower than 40%.
- if the boiler temperature is higher or equal to the temperature set up by the turning button of the
boiler thermostat, the fan switches off.
- the ventilator switches on again after decreasing the boiler temperature in o 5°C comparing to the
set up temperature.
The regulation of boiler ensures that the pump for central heating switches off when the temperature
of oulet water in the boiler decreases under 60°C. The pump switches on again by the temperature
higher than 65°C. This is a prevention against tarring and the water steam condensation in the
boiler hopper.
To prevent explosion of accumulated gas during ignition, the boiler regulator ensures purging of
gas in the boiler in 5 seconds and then each minute until 9 minutes according to the position of the
turning post-purge time button in the rear part of the regulator. During the set up there is always
information on the display which lasts 2 seconds (P1,...., P9, P-). In case you do not wish purging
of gas in the boiler, it is necessary to set up (P--).
To make the process of burning up the boiler stable, there is a burning up system installed in the
regulator. After plugging in or stopping the alarm the regulator is automatically set up to the process
of burning up and this mode is signalled by a shining dot on the display. The process of burning up
is finished when the dot stops shining and the boiler temperature reaches the value set up by the
