The basic version of electronic control unit without expander allows to connect pump with
AK 4000S power board. The operation of pump depends on selected hydraulic schema
and boiler temperature. Using two methods of pump control, by pulse or permanent
running.
Pulse running
allows the pump to go on and off within specific time interval. Pump activity
depends on the boiler output temperature. The main advatage is protection of the boiler
against low-temperature corrosion.
Permanent running
is used with 3-way thermostatic valve or Ladomat installation. See
chap. 10.4.
The pump operation is indicated by a flashing symbol on the display.
Discharge fan „2“ is designed to eliminate smoke in the boiler room area during refueling
VIGAS boiler. In case chimney does not comply with minimum parameters „A“ a „B“ it is
recommended to install discharge fan. This shall be installed between chimney flue and
chimney body. Fan capacitor „3“ shall be mounted to the side. It shall be connected to the
power board unit AK 4000S. It comes in two sizes depending on chimney diameter.
V25 (code 0507) – for VIGAS 16,18DPA, 25, 29 UD.
V80 (code 0508) – for VIGAS 40, 60, 80, 100.
As standard in the boilers VIGAS, one load is sufficient for 12 hours of operation which
means that it uses less than 30% of rated output. In view of the life of the boiler it is
preferred that the boiler operates at least at 50% of rated output. If the boiler VIGAS is used
with ACCU tank, 100% of rated output is used to achieve the desired boiler temperature. If
there is current requirement for heating, 100% output of the boiler is divided into charging
ACCU tank and heating. In this case, the tank is recharged by the excess output of the
boiler. In view of the fact that the boiler and ACCU tank is hydraulically connected to each
other, the temperature of the ACCU tank and the boiler rises to the desired temperature of
the boiler together. After exceeding this temperature by 10°C, boiler goes into the
attenuaton
(0% boiler output). In this mode, heating and charging ACCU tank is
managed solely by means of pumps. The great advantage of this system control is that in
the attenuation mode, it is possible at any time to add the fuel to the boiler, without
overheating of the ACCU tank, which in practice increases the time between fuel loading.
The automatic re-heating up takes place only after the exhaustion of ACCU tank at the
selected temperature
MinT
. ACCU tank minimal temperature volume can be adjusted
from 20°C to 70°C. After burning out of fuel and decrease of chimney temperature to the
boiler set
end
, the boiler will shut down. In a combined automatic boiler VIGAS 18 DPA,
after burning out of fuel "wood" boiler will automatically switch to fuel "pellets" and continue
heating another few days.
NOTE:
For all hydraulic circuits with ACCU tank, there must be a thermometer for ACCU
tank (code 3032) connected to regulation AK4000 and its location to insert at the top of the
accu. tank.
