Gasifying boiler Vigas
The servo-controlled flap will move to open
position (servo 100%) when
„ENTER“ button is pressed. Consequently, the following sequence
100%
down to 45% will move the flap to retain the lambda sensor value of
λ
1,35.
When displaying servo at 45%, secondary air is closed. When
displaying 0% primary a
ir is also closed. The flap will move to position
0% only when boiler is in the „OFF“ or „END“ phase.
In the heating phase, the boiler gas exhaust temperature is lower then
the
minimum set-up exhaust gas temperature
. Minimum and maximum
temperatures can be modified in boiler set-
up parameters. Minimum
standard exhaust gas set-up temperature is up 90°C and maximum set
-
up temperature is 220°C.
Boiler can be in heating mode for up to 60
minutes with minimum of 2min. If boiler does not reach burning phase in
this time, it will automatically shut down – sign „END“.

6.1.2 Boiler active – heating phase „On“
6.1.3 Boiler active – burning phase
6.1.4 Add fuel, boiler shut-down (manual control)
6.1.5. Boiler shut-down (automatic)
The burning phase is active, when the exhaust gas temperature is
(
end) +10 °C or after reaching desired temp. Burning phase is
controlled by PID regulator on the basis of chimney and boiler temp.
If the
temperature rises 1°C above desired temp., the output will be 0
%. If it
decreases >2°C below desired temp., the output will start again.

By pressing „ “ the boiler fan is switched off.
Open chimney flap

finishes fuel reloading and the fan will be
switched on. During fuel reloading, the servo-
controlled flap remains in
the same positi
on as it was before adding fuel. When fuel reloading is
complete, the flap moves to the position (servo 100%).
Consequently,
the following sequence 100% down to 45%
will move the flap to retain the
lambda sensor value of λ 1,35. When displaying servo at 4
5%, secondary
air is closed. When displaying 0% primary air is also closed. The flap will
move to position 0% only when boiler is in the „OFF“ or „END“ phase.
When exhaust gas temperature drops under the set-up temperature
( end), the boiler is automatically switched-off. Sign „END“
will be
indicated on the display. By pressing the ENTER“ button twice, the boiler
will start operating again.
The visual graphic control is used for this operation.
To activate the
display driver, press small middle bu
tton ENTER. The graphic control
offers options: switch-off boiler, add fuel or cancel display driver.
