3.1. System description
A control unit controls the operation of a Veto heating system including a boiler and a burner.
The mixer transports fuel from the bin to the feeding screw. The feeding screw moves the
fuel to the burner head where they burn at a high temperature with the help of air blown in by
the combustion-air blower and heat up the boiler cleanly and odor-free.
The combustion air blower is on the whole time in operating condition and can be set to the
pause condition. Fresh fuel brought in by the feeding screw pushes the remaining small
amount of ash to the ash box of the boiler from which it must be removed at certain intervals.
Refer to the boiler manual. The optional moving grate and ash screw empty the ash
chamber automatically according to the set intervals.
The feeding screw of a burner pushes the fuel in according to preset time intervals. By
adjusting the feeding screw operation time, the amount of fuel burning in the fire jet and the
boiler's effectiveness are controlled.
The control unit controls the fire that heats up the boiler according to the preset operating
condition and pause times.
When the burning device is operating, the blower rotates the whole time. Operating condition
work time regulates the rotating time of the feeding screw. Operating condition pause time
regulates the pause time of the feeding screw. When the boiler water reaches the
temperature set in the boiler thermostat, the burning device shifts to pause condition. In this
case the burner operates the time set for the pause condition work time and shuts down for
the time set for the pause condition pause time.
3.2. Boiler thermostat
With the boiler thermostat the boiler water temperature can be set at least to 80°C in order to
reach the optimum performance of the boiler.
An overheating alarm is given when the water temperature reaches 100°C. The overheating
alarm is reset by pressing the reset button.
19
For further information about the boiler thermostat, refer to the corresponding manuals.
Figure 4 Boiler thermostat
3.3. Feeding screw thermostat
Feeding screw thermostat measures the surface temperature of the feeding chute and tube.
The alarm temperature of the feeding screw thermostat is 80°C, and the temperature where
the alarm is reset 69°C.
Figure 5 Feeding screw thermostat
20
3.4. Flue gas temperature sensor
The flue gas temperature sensor is a Pt-100-type rod sensor, which:
•
•
Measures the flue gas temperature between 0-500°C.
Monitors the flame.
The rod sensor is installed in the flue gas fitting of the boiler.
Figure 6 Flue gas temperature sensor type Pt-100
21
3.5. Capacitive sensor in the A•T log-2 control unit
When using fuel like wood chips, the long chips may block the fuel flow and then the
connection before the rotary feeder. To prevent a blockage by controlling the feed, a
capacitive sensor is used in the rotary feeder, in installations of two separate feeding screw
and silo screw motors. When adjusted correctly, the capacitive sensor cuts the feed by
stopping the silo screw when the fuel touches the sensor.
Figure 7 Capacitive sensor
Adjust the recognition distance for all fuel types so that the sensor recognizes only the fuel
that touches the forehead surface to avoid a temporary interruption to shut down the whole
burning device, for example, if a chip touches lightly the forehead of the sensor. The wiring
end of the sensor has a screw for adjusting the recognition distance between 2–16 mm. The
default setting is 16 mm. Turn the screw clockwise to grow and counter-clockwise to reduce
the recognition distance. Fuel that has become moist for some reason may require a new
adjustment for the capacitive sensor.
The sensor functions in a temperature between -25°C –80°C. The yellow LED of the sensor
is lit when the silo screw is stopped due to a block.
When the block reaches the rotary feeder, the logic rotates the feeding screw emptying it
using the preset operating and pause conditions. If the block stays in the rotary feeder, the
burning device is shut down with an alarm.
22
3.5.1. Testing adjustment of the capacitive sensor
o
o
Take a handful of fuel towards the forehead surface of the sensor.
The hand must be full of fuel so that the hand itself or the hand moisture does
not give a wrong result.
The sensor light is lit when the sensor recognizes the fuel.
When testing the recognition distance, the operating switch
must be in the 0 position. Ensure that nobody can rotate the
feed or the silo screw with the operating switch.

5. Installation
5.1. Preparing for installation
Before starting any maintenance work, switch off the current
with the main switch and wait for 15 minutes. Although the
control unit is dead, there still is a normal supply voltage
coming from the frequency converter.
Only an authorized electrician should perform the electrical
installation which must comply with the wiring diagrams inside
the control unit.
Mount the control unit so that it does not, even during a fault,
cause a fire hazard to the mounting base or the attaching
structure of the unit.
•
•
•
The burner is driven by a three-phase voltage (50 Hz, 400 V AC) and it needs a
signal from the boiler to start to operate. The signal is given by an adjustable
thermostat which includes a delimiting thermostat (a boiler thermostat with an
overheating protection which is reset manually).
Install the main power switch near the exit of the boiler room.
Place the control unit on the wall in the boiler room according to the electric safety
regulations. A recommended place for the unit is opposite the feed door of the boiler
because it eases up the lighting stage.

Do not adjust the pause time of the maintenance state of the fire too short or for the pulse
too long because the boiler water is already hot and could be overheated as a result of
incorrectly set maintenance fire. It could cause the overheating protection to go off and the
burner to go out. If the maintenance fire has been adjusted during the cold season, it may
cause the boiler to overheat in the summer.

The moisture content, particle size, thermal value, weight and
other parameters of the fuel affect the efficiency of the burner
so that using these values may produce different boiler
outputs. Therefore, no reference values can be given as to the
positions of the air-adjustment plate.
6.6. Monitoring the flue gas temperature
•
Monitor the flue gas temperature (EXIT GAS TEMPERATURE) on the monitoring page
3.
The gas temperature can be monitored between 0-500°C.
The flame monitoring delay is 10 minutes and an alarm is shown on the display when the
flue gas temperature is below 80°C or over 490°C for the time in question.
6.7. Adjusting the boiler thermostat
•
Adjust the boiler thermostat on the monitoring page 3 to at least 80°C in order to attain
the optimal operating efficiency of the boiler.
Adjusting the thermostat affects the temperature of the flue gases as well. The
temperature of the flue gases in the chimney must not fall below the dew point.
Otherwise the moisture in the flue gases condenses and causes the chimney to crumble.
If there is an acid-resisting inner pipe in the chimney, the condensing moisture may flow
down and in the worst case corrode the rear part of the boiler. If the temperature of flue
gases is set too high, the heat is wasted.

6.8. Setting the ash screw work and pause times
•
•
Set the ash screw work time (ASH SCR W. TIME) and pause time (PAUSE TIME) on the
monitoring page 4.
Set the ash screw work and pause times according to the operating and pause condition
work and pause times (monitoring page 1).
42
The ash screw pause time is calculated in 0.1 second intervals. When the feeding screw
rotates 0.1 s the ash screw pause time shortens 0.1 s.
Ash screw works automatically emptying the ash chamber according to the preset work
and pause times. The default setting value for ash screw work time is 5 s. and for the
pause time 120 s.
6.9. Setting the moving grate pause time
•
•
Set the moving grate pause time (FIRE GR P. TIME) on the monitoring page 5.
Set the moving grate pause time according to the operating condition work and pause
times (monitoring page 1), pause condition work and pause times (monitoring page 2)
and the ash screw work and pause times (monitoring page 4).
The moving grate pause time is calculated in 0.1 s. intervals. When the feeding screw
rotates 0.1 s, the moving grate pause time shortens for 0.1 s.
The moving grate automatically empties the ash chamber. The grate makes one
movement after the moving grate pause time (FIRE GR P. TIME). The default value for
the moving grate pause time is 120 s.
6.10. Setting the after-blow time
•
Set the blower after-blow time (AFTER-BLOW) on the monitoring page 5.
It is the after-blowing time when the device shifts from operating condition to pause
condition. The device shifts to a pause condition when the temperature set in the boiler
thermostat is reached. The default value for the after-blow time is 5 s.
6.11. Setting the feeding screw reversing time
Do not operate the spring-driven unloader backwards more
than 5 seconds.
The reversing time can be used to improve the fuel feed if there are blocking items in the
fuel, for example bigger pieces of wood.
•
Set the feeding screw reversing time (REVERSING TIME) on the monitoring page 6.
In a burning device, it is possible to rotate the feeding screw backwards according to the
preset time REVERSING TIME. If the time has been reversed, that time is added to the work
times of the operating and pause condition.
43
When the reversing time is increased, the work times of operating condition and pause
condition increase in the logic but the increase is not shown on the monitoring pages.
The default value for feeding screw reversing time is 0 ms and the high limit 5000 ms.
6.12. Adjusting the blower operation
•
Set the blower operation on/off for the pause condition during the feeding screw
operating time on the monitoring page 7 (BLOWER PAUSE). The default value for
BLOWER PAUSE is “001”.
o
o
The blower is in operation in the pause condition when BLOWER PAUSE is set
to “001”.
The blower is not in operation in pause condition when BLOWER PAUSE is set
to “000”.
6.13. Setting the work time of the feeding screw
•
Set a longer work time in the beginning of operating condition for the feeding screw on
the monitoring page 7 (BOOST). The operating condition work time doubles and there
are three double-work periods. The default value for BOOST is “000”.
o
o
The boost effect is in use when BOOST is set to “001”.
The boost effect is not in use when BOOST is set to “000”.
6.14. Setting the automatic restart
•
Set the automatic restart after a power failure on the monitoring page 7 (RESTART).
After the power is restored, the burning device starts in operating condition or in pause
condition depending on the boiler thermostat. The default value for RESTART is “001”.
o
o
The restart function is in use when the RESTART is set to “001”.
The restart function is not active when the RESTART is set to “000”.
If the restart function is not in use, the instruction THE BURNING DEVICE IS
STARTED WITH THE OPERATING SWITCH IN BLOWER POSITION is shown
on the display after a power failure.

7. Lighting and burn control
Before lighting the device for the first time, check that the settings are made according to this
manual. For further information, refer to the burner manuals.
7.1. Lighting with the control unit
1. Turn the operating switch to the 0 position.
2.
Turn the screw manual operating switch to the half way of the fire jet.
The fuel is lighted manually through the feed door of the boiler. It is safest to light a warm
boiler with birch bark, paper or other suitable lighting material.
Do not use lighter fluid to light the boiler.
48
3. Start the fire by turning the operating switch in the BLOWER position. The blower
operates without interruptions.
4. Hold the switch in this position for about 5 min or until the fire has properly lit.
5. Turn the operating switch to the AUTO position.
If the burner head is not hot enough when the operating switch is turned into the AUTO
position, the fuel coming to the burner head may force the fire into the ash box. Then the
fire must be lit again.
The feed door of the boiler can be opened and the lighting, fuel and flame size can be
monitored. If necessary, feed more fuel to the fire jet.
When a completely cold combustion chamber is lighted for the
first time, the manual operation phase must be continued as
long as the flue gas temperature is 80°C.
7.2. Adjusting the operating efficiency
•
Adjust the operating efficiency on the monitoring page 1 by setting the pause time.
In order to obtain good operating efficiency, the burner should be adjusted so that it operates
for as long as possible and the pause period set by the thermostat is as short as possible.
Once the values are adjusted properly, power is added by reducing the pause time of the
power drive.
49
7.2.1. Adjusting the blower air opening
The necessary amount of air needed in the burning of the fuel is provided to the burner head
by adjusting the air aperture of the blower.
The necessary amount of air varies according to the quality of
the fuel and the amount of fuel to be burned in the burner
head at a time.
•
•
Observe the color of the flame. The optimal color is yellow. A smoky, sooty flame
requires more air. A short sharp flame (possibly with some blue color or a very light
flame) is a sign of too much air.
Open the adjustment shim of the blower between 5 and 6 on the scale.
Figure 14 Adjusting the blower air opening with the adjustment plate
50
7.3. Extincting the fire
1. Turn the operating switch to the BLOWER position. The feeding screw stops rotating.
2. Let the device cool down for 20-30 minutes.
3. Operate the burner head on the forced feeding of the feeding screw to give so much
fresh fuel into the burner head that all burning and charred fuel falls into the ash box.
Empty the burner head through the fire-tending hatch.
4. Operate the feeding screw backwards with the manual screw operating switch until
the burner head and the fuel on the feeding screw are clearly apart. It prevents
smoldering from the hot burner head to proceed into the fuel bin. The device is now
turned off.
7.4. Setting the ash screw
•
Set the work and pause times of Veto ash screw on the display.
The ash screw and moving grate are controlled from the TA control unit set for ash screw
and moving grate.
51
8. Troubleshooting
8.1. Alarms in the control unit
When an alarm is activated, the burning device shuts down and the display shows an alarm
message. After checking the cause of the alarm the device can be started normally. The
burning device is started by resetting the alarm with the operating switch in the BLOWER
position.
8.1.1. Alarm messages
FLAME MONITORING ALARM!
•
•
•
The flue gas temperature in operating condition is below 80°C or above 490°C for 10
minutes.
The burning device is shut down and the display shows the alarm and an instruction
THE BURNING DEVICE IS STARTED WITH THE OPERATING SWITCH IN
BLOWER POS.
The alarm relay 1 is switched on. The relay transmits the alarm information to the
wanted device, for example a lamp, or a separate GSM alarm center (not included in
the delivery).
BOILER WATER OVERHEATING ALARM! RESET THE THERMOSTAT.
•
•
•
•
•
•
•
•
The boiler water temperature reaches 100°C.
The burning device is shut down and the display shows the alarm BOILER WATER
OVERHEATING ALARM! RESET THE THERMOSTAT.
The alarm relay is switched on. The relay transmits the alarm information to the
wanted device, for example a separate GSM alarm center, a lamp.
Reset the boiler water overheating alarm by pressing the reset button.
The display shows an instruction THE BURNING DEVICE IS STARTED WITH THE
OPERATING SWITCH IN BLOWER POSITION.
Wait the boiler water temperature to go back to the setting temperature when the
overheating alarm can be reset with the operating switch in the BLOWER position.
The alarm is reset when the text THE BURNING DEVICE IS STARTED WITH THE
OPERATING SWITCH IN BLOWER POSITION. disappears from the display.
Check on the status page when the burning device is in operating condition. The
boiler thermostat adjustment contact I 4 is closed in this case.
52
•
The boiler thermostat setting temperature can be checked with the temperature
regulator of the thermostat. When the regulator is turned, the boiler thermostat clicks
when the real temperature is met. In order to prevent the boiler water overheating
alarm to occur, the work and pause times of the operating and pause condition must
be set correctly.
FEED SCREW OVERHEATED!
•
•
•
•
•
•
The feeding tube temperature exceeds the alarm limit, 80°C.
The feeding screw is rotated eight times with five times longer operating condition
work and pause times or pause condition work time. This way the fuel that is possibly
burning in the feeding tube, is pushed to the boiler.
The alarm is reset when the temperature goes below 69°C. If the feeding tube
temperature goes below 69°C before the feeding screw has been rotated 8 times, the
alarm resets itself and the burning device starts automatically to operate normally. If
the feeding tube temperature does not go below 69°C when the feeding screw has
been rotated 8 times, the burning device shuts down and the display shows the alarm
FEED SCREW OVERHEATED!. During a device fault alarm the alarm relay switches
on in the logic. The relay transmits the alarm information to the wanted device, for
example a separate GSM alarm center, a lamp.
The feeding tube temperature must go below 69°C when the display shows the
instruction THE BURNING DEVICE IS STARTED WITH THE OPERATING SWITCH
IN BLOWER POSITION. if the device has been shut down.
Reset the feeding screw overheating alarm with the BLOWER position of the switch,
when the feeding tube temperature has gone below 69°C. Check on the logic status
page that the feeding screw temperature has gone below 69°C. The feeding screw
thermostat adjustment contact I 6 is then closed.
If a feeding screw alarm takes place, check the operating and pause condition work
and pause times. Depending on the draught of the chimney and the fuel, the work
and pause times must be reset.
ROTARY FEEDER BLOCKED! REMOVE THE BLOCKAGE THROUGH THE
INSPECTION HATCH.
•
•
•
•
Only in the A•T log-2 control unit.
The rotary feeder is blocked, the logic stops the silo screw and rotates the feed screw
empty with the preset operating and pause condition work and pause times and waits
for the blockage to disappear.
The yellow LED of the capacitive sensor is lit when a blocking object stops the silo
screw rotation. If the blockage is not cleared, the burning device shuts down with an
alarm.
During the alarm the alarm relay 2 switches on in the logic. Opening or closing alarm
information is provided by the relay.
53
•
When the blocking object is removed and the control unit is live again, an instruction
is displayed: THE BURNING DEVICE IS STARTED WITH THE OPERATING
SWITCH IN BLOWER POSITION. The alarm can be reset with the operating switch
in BLOWER position. The status of the capacitive sensor can be checked on the
status page.
8.2. System malfunctions
Wear heat-proof and incombustible clothing to protect your
skin and hair and keep a Plexiglas visor available in the boiler
room in case a backfire has proceeded into the fuel bin.
8.2.1. Backfire in the feeding tube
Although the feeding screw is emptied during a feeding screw overheating alarm, a backfire
might reach the feeding tube. The display shows an alarm FEED SCREW OVERHEATED!
and the feeding tube feels hot or has become black and the water container should also be
empty.
Fault
Backfire in the feeding tube
Solution
•
Drive fuel to the combustion chamber of the boiler
using the screw manual operating switch until new
fuel reaches the fire jet.
•
Check that the fuel amount in pause condition is
sufficient (or not too large).
•
Check that the burning device is air-tight, the
chimney does not draw too strongly and that the fuel
is not too dry.
8.2.2. Backfire in the container
Be careful when opening the fuel bin lid because flue gases
may come out and the smoldering fire may blaze up when
getting more oxygen.
If the fire has spread into the environment, or the fuel bin is
glowing strongly, call for help.
After closing the cover, if the fuel bin is still glowing strongly,
cool the bin by pouring some water on top of it, until the fire
begins to choke inside the bin. Be careful when opening the
cover of the fuel bin to pour water on the embers because the
steam and flue gases may be burning hot.
54
Fault
Backfire in the container
Solution
•
If the backfire has reached the container turn the
operating switch to the 0 position.
•
Ventilate the container.
•
Estimate the extent of the backfire by the surface
temperature of the fuel bin. If the coat of paint on the
feeding pipe, and possibly on the side of the fuel bin
around the joint has turned black, feed fuel using the
forced feeding of the feeding screw into the
combustion chamber of the boiler until the incoming
fuel smolder just a little or not at all.
•
At times the smoldering fuel has to be removed
through the ash hatch of the boiler. Open the cover of
the fuel bin and pour or spray water into the bin if
possible.
•
If you have forgotten to close the bin lid, the backfire
may be very strong. Having the protective clothing on
and using a suitable instrument, try to close the bin
lid.
8.2.3. Blower is not operating and fuel is fed seldom
Fault
The blower is not operating
and fuel is fed seldom
Cause
•
Check the status page in the control unit if the device
has shifted to pause condition. In that case, the
feeding screw or feeding and feeding screw are not
operating for a long time according to the pause
condition work and pause times.
8.2.4. Flame monitoring alarm is displayed
Fault
Flame monitoring alarm is
displayed
Cause
•
The burner may be out of fuel.
•
An unsuitable object might have been shifted with the
fuel to the fuel container and the feeding screw. In
this case check that the motor protection relay F2 is
in up position.
•
Wrong operating condition work and pause times
may cause the alarm. Check the times and restart
the burning device.
55
8.2.5. Unsuitable object has entered the feeding screw
Make sure that nobody is near the feeding tube inspection
hatch, so it is possible to drive the screw backwards with the
screw manual operating switch, if necessary.
Fault
Unsuitable object has
entered the feeding screw
Solution
•
Turn the operating switch to the 0 position.
•
Drive the feeding screw backwards and forwards
using the screw manual operating switch. If the
feeding screw does not stall when driving forwards,
the object is removed. Return to normal operation.
•
If the feeding screw and the motor do not rotate with
the screw manual operating switch turn the operating
switch to the 0 position.
•
Open the feeding tube inspection hatch.
•
Turn the motor protection relay switches to the up
position.
•
Remove the object that caused the interruption
through the inspection hatch.
•
Ensure that the feeding screw functions flawlessly
and close the feeding tube inspection hatch. Restart
the burner.
•
If the motor operates but the feeding screw does not
rotate, a fault is caused by a foreign object or
compact fuel stuck on the bottom of the screw
trough. To clear the fault, remove the fuel from the
silo until the fault is located. Remove the cause of
the fault and clean the screw trough of the compact
fuel before doing any repairs.
8.2.6. Burning device has stopped and cooled down
Fault
The burning device has
stopped and cooled down
Solution
•
Check the device for possible damages caused by
overheating.
•
Reset the display. Refer to Alarm messages.
56
8.2.7. Efficiency of the device weakened
Fault
Efficiency of the device
weakened
Solution
•
Check that the blower works properly. If the propeller
blades have gathered dust clean them.
•
Check the joints of the casting parts of the burner
head and the frame.
•
Check that the air holes of the burner head are open.
•
Check and empty, if necessary, the ash box of the
burner head.
•
When using wood chips made from whole trees, use
up the contents of the fuel bin at times and remove
the layer of stick from the bottom.
8.2.8. Smoke coming into the bin
Fault
Smoke coming into the bin
Solution
•
Check that all the air-intake apertures of the boiler
are closed.
•
Check the air-tightness of the joints between the
chimney and the boiler, and all the joints of the
burner device to maintain a proper draught in the
chimney.
•
Check that there is no blockage in the chimney or the
chimney joint, and make sure that the draught in the
chimney is sufficient.
•
Check that there is not too much ash inside the
burner head.
8.2.9. Display shows STOP in the bottom right corner
Fault
The display shows STOP in
the bottom right corner
Solution
•
Insert the memory card with the logic software.
Refer to Loading a program to the logic.
8.3. Frequency converter malfunctions
For further instructions, refer to the manual of the frequency converter in question.
57
9. Disposal of the control unit
The control unit has to be disposed of in accordance with the local regulations in a waste
processing plant.
Most of the material can be reused as raw material, for example, metal, plastic, batteries.
