4. BASIC CONFIGURATION OF VIGAS BOILER WITHOUT
EXHAUST FAN
The advantage of the exhaust gas thermometer is to control the maximum exhaust gas temperature, and when this is
reached by the boiler, a fan will come into operation to lower the engine RPM. This results in higher boiler efficiency
and lower fuel consumption. If installed with an accumulator tank, the thermometer will shut down the boiler when fuel
is burned down. The water temperature inside the boiler and accumulator tank has no influence on boiler shut down.
4.1 VIGAS BOILER CONTROL
4.1.1 Boiler activation
4.1.2 Boiler active – heating phase, heating regime „On“
4.1.3 Boiler active – burning phase „74°C“
4.1.4 To add fuel or boiler shut-down (manual control)
By pressing „ “ fan will be switched off. Use lever t
o open chimney flap
and consequently open the upper door. Fuel can be added if necessary.
After reloading close the upper door and
chimney flap (pic.12.4).
By
pressing „ “ refuelling will be ended. Fan will switch on automatically.
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 bu
rning phase in
this time, it will automatically shut down – sign „END“.
OFF will be displayed when the boiler is switched off. To START the
boiler press middle button ENTER.
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.
