Technical description of ATTACK DP PROFI:
During the operation, the display is showing the current temperature of outlet heating water.
Speed of the fan are controlled in this way:
- if during burning up proces 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
r4 = 40% to r9 = 90 %, rF=100%
40 - 100 %. (you can see it on the display, from ), 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.
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 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 thermostat. In case the
temperature in the boiler does not exceed 65 °C in 2 hours of burning up time, the regulator stops the
waste-gas ventilator and switches on the control light - missing fuel.
In the time of burning out the boiler when the temperature falls under 65 °C and this condition lasts
for more than 30 minutes, the regulator stops the flue-gas fan and the control light of missing fuel
shines on.
Missing fuel
When the temperature of heating water in the boiler falls under 65 °C and this condition lasts for
more than 30 minutes, the regulator stops the flue-gas fan and the control light of missing fuel
shines on. If in the burning up process the boiler temperature does not raise to more than 65°C,
missing fuel will be shining on the display after 2 hours. To start the regulation again, it is
necessary to:
- refuel the boiler;
- burn the boiler up
- turn the turning button of the boiler thermostat into the maximum left position and thus stop
the alarm
-wait until the control light of missing fuel flickers,
- by turning button of the boiler thermostat set up the required temperature of the boiler and the
regulator starts the process of burning up
