2. Design
Description
Heating with pellets with the use of the ATMOS A85 pellet burner has a lot in common with
natural gas or oil heating. However, there is a difference that burning of pellets produces a certain
quantity of ashes that must be removed from the burner and boiler in an interval to avoid impairment
of efficiency or affecting the functionality of the burner.
The ATMOS A85 pellet burner is supplied with automatic fuel ignition as standard. The assembly
of the burner, external conveyor and fuel bin work completely automatically during operation and
is controlled by an electronic control unit with the use of a flame sensor (photocell). In the burner
body the fuel and combustion air are supplied in such a way to ensure maximum efficiency and
environment-friendliness of fuel burning.
Normally only high-quality pellets with the diameter of 6 to 8 mm and length of 5 to 25 mm
should be fed into the burner. Pellets made of soft wood without bark, called white pellets, are
considered as high quality pellets.
Ashes are normally removed from the burner through the open door once every 7 to 30 days as
necessary. Fly-ash and dirt accumulated in the combustion chamber of the burner and boiler
considerably reduce the service life and output.
For this reason the basic version of ATMOS burner A85 is equipped with pneumatic cleaning
which cleanses the burner’s combustion chamber after every burn out or at regular intervals (factory
setting is 4 hours – parameter S42, S43). Thanks to pneumatic cleaning you can check or clean the
burner’s combustion chamber only once in a fortnight or a month.
It is recommended to thoroughly clean the inner parts of the burner once a year; for this operation
the burner should be removed from the boiler. For ideal cleaning of the combustion chamber (pot) of
the burner you can use a special vacuum cleaner or a poker.

4. Safety, burner installation and commissioning
Safety and connection of the burner to the boiler
WA R N I NG - Before starting the burner you must carefully read all the provisions of this
manual. At the same time you must observe all general safety regulations for work with
heating equipment resulting from the valid legislation.
• The premises where the equipment will be installed must comply with all fire protection regulations
EN
in accordance with valid standards and laws.
• The equipment must be positioned in such a way to ensure access for cleaning and removal of
ashes not only from the burner, but also from the boiler, flue gas duct and chimney.
• The burner must be installed to the boiler over a sealing cord, soft Sibral sealing or another
insulation and sealing material to prevent flue gas from escaping along the burner to the boiler
room. Under one of the nuts with the use of which the burner is attached to the boiler a SPECIAL
SHEET-METAL PART - END SWITCH STOP must be positioned. It is used to compress the
end switch that monitors the proper position of the burner on the boiler. This protective device
must not be omitted in any case as it is directly related to fire safety.
• The connection between the burner and the boiler must be properly tightened to prevent flue gas
from escaping to the boiler room.
•
During the installation you must make sure that the pellets can freely fall through the hose to the
burner. The connections between the hose, burner and conveyor must also be properly tightened.
Design and technical measures for increasing safety
• The ignition and combustion process is controlled by the electronic control unit by means of the
flame sensor - photocell. If the sensor does not sufficiently see the flame during operation, it will
automatically put the burner out of operation.
• The electronic control unit senses the speed of the burner fan and at any problems of the fan it
automatically puts the burner out of operation.
• On the burner frame there is an end switch and end switch stop that does not make it possible to
start to burner if the burner is not properly fixed to the boiler (e.g. after cleaning of the burner).
If during normal operation of the burner the end switch gets disconnected, the burner will be
automatically put out of operation. If at the start after two attempts with the fuel supply and one
attempt without the fuel supply the pellets are not ignited, the burner will be automatically put out
of operation.
• If during normal operation of the burner the fuel bin runs out of pellets, the burner will try a new
start and subsequently will be put out of operation. After replenishing pellets in the fuel bin and
drawing pellets to the conveyor you can start the burner by merely turning off and on the burner
switch on the boiler panel.
• The flexible transparent hose between the burner and external conveyor is made of special material
that melts at high temperatures and the hose will change to a spring that will separate the burner
from the fuel bin.
10-EN
www.atmos.cz
Operation and Maintenance Manual - EN
• The safety thermostat - located on the fuel supply pipe of the burner, will shut down the burner
if its temperature is higher than 95 °C. Thus, it protects the burner from return ignition of pellets
in the conveyor and at the same time from operation with clogged flue gas exhaust from the boiler
(e.g. in case of a failure to remove dust from the boiler, flue gas duct and chimney). The safety
thermostat will also put the burner out of operation in case the hose between the burner and
conveyor gets perforated to prevent flue gas from escaping to the boiler room.
INFO - After any shutdown of the burner when an error message (ALARM) appears on
the display it is necessary to immediately find the cause and remove it. After removing the
cause of the error you can start the burner by merely turning off and on the burner switch,
which is located on the boiler panel.
Basic dimensions of the opening for installation of the burner in a boiler
In the case of the D80P, P80 boilers the boiler comprises a frame with a sealing cord - 18x32 mm.

5. Type of environment and location of the boiler with the
burner in the boiler room
Boilers with a pellet burner may be used in the AA5/AB5 basic environment in accordance with
the ČSN3320001 standard. Boilers must be installed in a boiler room with guaranteed sufficient supply
of combustion air. It is unacceptable to
locate boilers on residential premises
(incl. corridors). The cross-section of the
EN
opening for supply of combustion air to
the boiler room must be at least 350 cm

6. Chimneyn
A boiler with a burner must always be connected to the chimney vent with consent of the
responsible chimney maintenance company. The chimney vent must always produce sufficient
draught and exhaust flue gas to the free atmosphere in virtually all operation conditions. For proper
function of boiler the separate chimney vent must be properly dimensioned as the combustion, output
and service life of the boiler depends on its draught. The draught of a boiler directly depends on
its cross-section, height and roughness of the inner wall. No other device may be connected to the
chimney to which a boiler is connected. The diameter of the chimney must not be smaller than the
outlet on the boiler (min. 180 mm). The chimney draught must achieve prescribed values (see the
technical specifications in the boiler manual). However, the boiler must not be excessively high so as
not to reduce the efficiency of the boiler and not to disturb its combustion (tear the flame). In case of
too strong draught install a throttling flap or draught reducer in the flue gas duct between the boiler and
the chimney.
Guideline values of dimensions of the chimney cross-section:
20 x 20 cm height 9 m
Ø 20 cm height 10 m
The exact determination of chimney dimensions is defined by the ČSN 73 4201 standard.
The prescribed chimney draught is specified in the “Technical data” chapter of the manual
of the particular boiler.
12-EN
CAUTION - The draught of the chimney during operation must ensure the minimum
vacuum of 2 Pa in the combustion chamber of the boiler.
www.atmos.cz
Operation and Maintenance Manual - EN
7. Flue gas duct of the boiler
The flue gas duct from the boiler must lead to the
chimney vent. If the boiler cannot be connected directly to
the chimney vent, the corresponding flue gas duct adapter
must be as short as possible with regard to the particular
conditions, but not longer than 1 m, without additional
heating surface and it must rise towards the chimney. Flue
gas ducts must be mechanically strong and leak-proof for
flue gas and cleanable inside. Flue gas ducts must not lead
through other owners‘ residential or commercial units. The
inner cross-section of the flue gas duct must not be larger
than the inner cross-section of the smoke uptake and must
not get narrower towards the chimney. The use of smoke
elbows is not suitable. Designs of passages of flue gas ducts
through structures of flammable materials are defined in
Annexes 2 and 3 of ČSN 061008 and are mainly suitable for
mobile units, wooden huts, etc.

8. Fire protection within the installation and use of heat appliances
Extract from ČSN 061008 - Fire safety of local appliances and sources of heat
Safe distances
On installation of an appliance the safe distance from building materials must be maintained, at
least 200 mm. This distance is valid for boilers and flue gas ducts located near flammable materials
of the B, C1 and C2 flammability class (the flammability class is specified in tab. no. 1). The safety
distance (200 mm) must be doubled if boilers and flue gas ducts are located near flammable materials
of the C3 class (see tab. no.1). The safety distance must be doubled if the flammability class of
flammable material is not evidenced. The safety distance may be reduced to a half (100 mm) if you
use a non-flammable heat insulating panel (asbestos panel) with the thickness of at least 5 mm,
located 25 mm from the protected flammable material (flammable insulation). A shielding panel or
protective screen (on the protected object) must exceed the outline of the boilers (incl. flue gas ducts)
at each side by at least 150 mm and the top surface of the boiler by at least 300 mm. A shielding panel
or protective screen must also be used to protect fixtures of flammable materials if the safe distance
cannot be maintained (e.g. in mobile units, huts, etc. - more details in ČSN 061008). The safety
www.atmos.cz
EN-13
Operation and Maintenance Manual - EN
distance must also be maintained in case of installation of fixtures near boilers.
If boilers are located on a floor of flammable materials, they must be installed on a non-flammable,
heat-insulating pad, exceeding the ground plan at the side of the feeding and ashpan opening by at
least 300 mm before the opening - at the other sides by at least 100 mm. As non-flammable, heat
insulation pads you can use all materials of the A flammability class.
Tab. nr.1
Flammability classes of
EN
building materials and
products
A - no ammability
granite, sandstone, concrete, brick, ceramic tiles, mortar, re-resist-
ant plastering, etc.
B - dicult ammability
C1 - poor ammability
C2 - medium ammability
C3 - high ammability
WARNING - In circumstances leading to the danger of transient ingress of flammable
gases or vapours and during work that might result in a temporary risk of a fire or explosion
(e.g. gluing of linoleum, PVC, etc.) the boilers must be put out of operation in time before
the occurrence of the danger. No objects of flammable substances may be put on the
burner and boiler in a smaller distance than the safe distance from them (more - see
ČSN EN 13501-1).
In short, do not put any items that could easily catch fire in the vicinity of the boiler.

11. Connection of the boiler and burner to the electric mains
Only connect the burner to the 230 V, 50 Hz electric mains via the boiler with a mains cable
without a plug so that the conductors (L, N) should not be interchanged. The mains supply must be
replaced with the same type by a repair organization. The boiler must be positioned in such a way
that the connector on the burner can be within the operator’s reach (in accordance with ČSN EN
60335-1).
CAUTION - Boilers with a burner may only be connected by a qualified person in accordance
with all the relevant valid regulations of the particular country while great attention must be
paid to safe earthing of the boiler.
After the installation of the burner on the boiler the technician must connect the burner and
subsequently the entire boiler to the electric mains in accordance with the attached wiring
diagram (page 20).
Connection:
Between the burner and boiler a six-wire cable is newly used that is connected with one end to
the burner with a 6-pin connector (part of the burner) and the other end with a 6-pin connector to the
boiler.
EN
The meaning of the conductors is as follows:
Black – phase L1 (230V, 50Hz) – With the main switch of the boiler on the black conductor is
•
permanently live (independently of the control thermostat of the boiler). It is the supply voltage of
the burner. This phase must be fuse protected via the safety thermostat of the boiler (95 - 110 °C).
• Brown – phase L2 (230V, 50Hz) – The brown conductor is controlled by the control or another
thermostat on the boiler panel. It brings the phase, impulse for the burner start. It is perceived as
the starting (ignition) and shutdown signal. This phase must also be fuse protected via the safety
thermostat of the boiler. (95 – 110 °C).
• Grey - reserve R (L3) (230V/50Hz) - The grey conductor is connected directly to the 6-pin
connector on the boiler. It serves as the free reserve for various functions of the boiler, characterized
with the S6 parameter. In this case it serves to control the solenoid valve of the burner‘s pneumatic
cleaning.
• Red - reserve R2 (230V/50Hz) – The red conductor is connected directly to the 6-pin connector
on the boiler. It serves as the second free reserve for various functions of the boiler, characterized
with the S14 parameter. In this case it serves to control the compressor of the burner‘s pneumatic
cleaning.
• Blue - N – Neutral – The blue conductor is connected to the neutral conductor.
• Yellow and green - PE – Protective Earthing – The yellow and green conductor is connected to
the earth.
NOTE - The burner and the boiler fan are newly connected by a three line cable of the speed
sensor. One end of the cable connects to the burner by a 3-pin connector (part of the boiler
fan cable) and the other one connects to the draught fan connector in the boiler casing.

15. Commissioning
CAUTION - The system may only be put in operation if the burner is connected to the
boiler, the boiler to a chimney with sufficient draught via a flue gas duct and in the fuel bin
there is a sufficient quantity of pellets of the corresponding quality. Pellets made of soft
wood without bark, i.e. white pellets with the diameter of 6 to 8 mm and length of 5
to 25 mm are considered as high-quality pellets. These pellets do not cake. Burning of
dark pellets or pellets with bark that contain visible dark dots produces cake that must
be removed from the burner mouth once a day. Otherwise the combustion chamber
and the feeding hose from the conveyor will get clogged.
For this reason the basic version of ATMOS burner A85 is equipped with pneumatic
cleaning which cleanses the burner’s combustion chamber after every burn out
or at regular intervals (factory setting is 4 hours – parameter S42, S43). Thanks to
pneumatic cleaning you can check or clean the burner’s combustion chamber only once
in a fortnight or a month.
INFO - The pellets have to be stored in dry and clean containers (areas). When filling
the fuel bin, the pellets must not be contaminated by foreign objects that could cause a
blockage of the conveyor or have an impact on the burning process.
Operation and Maintenance Manual - EN
EN
Requirements for the external conveyor and pellet bin at the first start of the burner:
• The worm conveyor must be positioned in the bin in such a way to be able to easily pick up
pellets. In the case of a fuel bin whose pellet level will be higher than 2 metres a roof will have
to be installed over the conveyor to prevent blocking of the conveyor. Blocking of the conveyor is
caused by dust in the pellets in combination with high pressure caused by the height of the pellet
level. ATMOS 250, 500 and 1000 l pellet bins do not require the installation of the roof.
• The hose between the burner and conveyor must be tensioned, properly fixed and must have such
an inclination to enable trouble-free falling of pellets to the burner.
• The connector of the work conveyor must be plugged into the socket on the burner.
Procedure of drawing pellets to the conveyor
• Plug the connector of the external worm conveyor to a standard wall socket. As soon as the first
pellets get over the top point and start to fall to the burner via the elastic hose, plug the connector
of the external worm conveyor back into the socket on the burner.
Normal operation:
• On the control thermostat on the boiler panel set the required operation temperature of 80 - 90 °C
and turn on the switch of the burner located on the boiler panel and the main switch.
The STARTup mechanism consists of the following steps:
At the start the worm conveyor and the ignition spiral are started (the fan on the burner and the boiler
•
is stopped).
• The worm conveyor will run for the time set by parameter T1, necessary for the delivery of the
amount for pellets for optimum ignition. After the delivery of the ignition amount of fuel the
www.atmos.cz
EN-21
Operation and Maintenance Manual - EN
worm conveyor will stop. The burner fan will be started at the ignition speed - parameter S2
as well as the extraction fan.
• After the ignition of pellets the photocell will sense light, which will cause the ignition spiral to
switch off with a slight delay.
• The burner will pass over to the stage of perfect burning of fuel - set by parameter T7.
The OPERATION algorithm consists of the following steps:
EN
• When the fuel burns perfectly, the burner will get to the stage of gradual increase of the power
to the nominal value - parameter T10.
• After achieving the nominal power the burner works in the normal mode until the heating system
or the accumulation tank is heated to the required temperature. The power of the burner results
from the hourly quantity of pellets delivered by the worm conveyor to the combustion chamber.
The worm conveyor works in the intermittent mode set by parameters T4 and T6. Parameters
T4 and T6 are set in accordance with the instructions on page 25.
•
After setting the nominal power of the burner you must also set the amount of combustion air
necessary for complete burning of fuel. The setup is done using air flap of the burner fan and by
changing speed of the burner fan (parameter S3). The exact setting should be carried out by a
trained person with the use of a flue gas analyzer.
The burning out algorithm is designed as follows:
•
After the achievement of the set temperature at the boiler thermostat (e.g. 85 °C) or temperature
in the accumulation tank - temperature at the bottom sensor (TS), the electronic control unit of the
burner will switch off the external worm conveyor. Thanks to this, the pellets in the combustion
chamber will burn out. Optimal burning out of pellets in the combustion chamber is additionally
supported by the operation of the burner fan for a certain time - parameter T5. After subsequent
drop of the temperature of water in the boiler or discharge of the accumulation tank - temperature
at the top sensor (TV), the burner will be re-started in the same way as described in the text above.
If the accumulation tank is connected to a solar exchanger and activating functions for automatic
optimization (switching) of sensors, parameter S15 = 3, the burner may be turned off by sensor TK
instead of sensor TS.
The other algorithms are designed in the following way:
• If the first attempt for ignition with fuel supply fails, the burner will repeat the whole algorithm.
After the second unsuccessful attempt for ignition with fuel supply the burner will proceed to the
third attempt during which the fuel is not supplied any longer, but only the ignition spiral is active.
After this unsuccessful attempt the burner will be put out of operation as the system has probably
run out of pellets or a fault has occurred.
• In case of a short-term interruption of power supply to the burner, the burner will automatically
renew its operation after performing diagnostic checks, complete burning out of pellets,
pneumatic cleaning of the burner and a new start.

Setting up required output and combustion quality:
Required output is set up by parameters T4 and T6
The real output is, however, also affected by pellet diameter and an angle of the conveyor. That is why
it is necessary to know that when conveyor angle or pellet diameter were changed after set-up of the
burner, the burner must be set up again.
Quality of combustion is set up with the fan‘s air flap in such way that the flame ends at the front
edge of the combustion chamber spherical space. This means that in boiler D80P, P80 flames fill the
EN
entire space of the combustion chamber. However, reaching of the flames as far as the spherical space
of the boiler‘s body must be prevented.
Accurate final set-up of combustion is to be done after the boiler had been in continuous operation
for 30 to 60 minutes. The best way is to use an exhaust analyzer. We recommend to set up the burner
so that surplus O2 in exhaust gas fluctuates between 7 to 10 % and average CO is less than 250 mg/
m3. Exhaust gas temperature must never drop below 110 °C and rise above 250 °C.
INFO - Although the burner has many functionalities (parameters), these only relate
to set up of the basic ones, which characterize output of the burner T4, T6 and quality
of combustion – fan‘s speed S3, air flap opening
Approximate recommended set up of the burner for separate outputs when using conveyors
DRA50 – 1.7, 2.5, 4 and 5 m, 6 mm pellets and the conveyor at an angle of 45°:

CAUTION - Parameter T4 must never be set higher than 9 s.
INFO – If necessary, when there is little space in the boiler room, you may shorten the conveyor
(screw) or its legs as you wish at any time, but in such way that the conveyor angle remains
smaller than 45°.
Minimum length of the pipe between the burner and the conveyor must be more than
30 cm. Maximum length of the pipe should not exceed 1 m.

a) S4 = 1 …. Photocell sensing
• Parameter S6 – characterizes the first reserve R - additional output - function … (3)
The first reserve R is used for controlling boiler exhaust fan.
EN
CAUTION – In the standard setting when parameter S1 is set to 2, you can connect to
the reserve terminal
(approx. 566 VA).
In the setting when parameter S1 is set to 4, which means that at the start both the ignition
spirals are activated simultaneously, you can connect to the reserve terminal R, R2, R5 and
R6 an appliance with the maximum current of 0.29 A (approx. 67 VA).
If:
a) S6 = 1…. If any fault occurs in the burner and the burner is shut down, the reserve relay will
be closed and the reserve output will be energized. Thanks to this you can start a spare source
of energy for heating of the building as e.g. a gas, electric or oil boiler.
b) S6 = 2….. If any fault occurs in the burner and the burner is shut down, the reserve relay will
be opened and the reserve output will not be energized. Thanks to this a signal can be sent to
an electrically backed up AB01 ATMOS GSM module controller that will send information that
there is a system fault or the system is not energized. This is the opposite logic (to S6 = 1), which
means that during normal operation the reserve is energized.
c) S6 = 3…… The reserve function as the output function for the burner fan, when the reserve
output is closed, is energized always when the burner fan is running (fan mode only 100 % or
OFF). This function is applied if you want the boiler fan or extraction fan in the chimney to run
together with the burner fan. This function is designed for direct control of an fan directly from
the burner (e.g.
D80P, P80,
R, R2, R5 and R6
DxxPX, PXxx).
an appliance with the maximum current of 2.46 A
d) S6 = 4…… The reserve function as the reversed function of the output for the burner fan,
when the reserve output is off, is not energized always when the burner fan is running. This
function is always activated if you connect the A25 burner with the AS25 set containing the
AD02 or AD03 module, which in this case controls the extraction fan of the boiler. Install the
www.atmos.cz
EN-27
EN
Operation and Maintenance Manual - EN
AD02 or AD03 module under the instrument hood of the boiler and connect it electrically
between the boiler terminal board and the extraction fan, see the wiring diagram.
This setting and connection with AD02 or AD03 module and special connector (jumper to main
switch) is standardly used for SP(X) boilers with the function for automatic start after wood
is burnt out activated (AUTOSTART – S34 = 1 or S34 = 2). Boiler exhaust fan is running
simultaneously with the pellet burner during the AUTOSTART function.
e) S6 = 5…… Reserve function as the output function for the Z1 ignition spiral when the reserve
copies the run of the ignition spiral.
f) S6 = 6….. Cleaning function of the combustion chamber or grill (flap). If the burner is in the
normal START, RUN and STOP mode, the output is not energized. The output is only energized
for the limited time T11, which continues immediately after the expiration of time T5 in the
STOP mode. It is not used with the A25 burner.
g) S6 = 7….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The
reserve output work independently of the condition of the actual output for the external worm
conveyor. This means that if the standard output for the external conveyor gets damaged, the
reserve will work independently in accordance with the same program, and therefore it can be
used as a replacement for the damaged output.
h) S6 = 8….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The
reserve works in dependence on the status of the actual output for the external worm conveyor.
This means that if the output for the external conveyor gets damaged, the reserve will be switched
off automatically. This function is suitable in situations when you need to control another external
conveyor that supplies (feeds) pellets from a larger distance to the main conveyor from which the
pellets fall directly to the burner.
i) S6 = 9….. Reserve function as the output function for the external worm conveyor, when the
reserve copies the run of the external worm conveyor, but with the difference that it does not cycle, but
runs permanently both during the drawing of the ignition amount and during both the times T4
and T6. Thus, the other external conveyor runs continuously and works independently of the status
of the actual output for the external worm conveyor. This means that if the output to the main external
conveyor from which pellets directly fall to the burner gets damaged, the reserve will keep working
independently. This function can be used in cases when you need to control another external conveyor
that supplies (feeds) pellets from a larger distance to a pellet bin at the boiler from which the main
external conveyor draws pellets to supply them directly to the burner. Caution - the other external
conveyor must always be controlled with an additional level sensor (level meter) that will maintain the
level of pellets in the pellet bin at the boiler.
j) S6 = 10….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor, but with the difference that it does not
cycle, but runs permanently both during the drawing of the ignition amount and during
both the times T4 and T6. Thus, the other external conveyor runs continuously, but it works in
dependence on the status of the actual output for the external worm conveyor. This means that if
28-EN
www.atmos.cz
Operation and Maintenance Manual - EN
the output for the external conveyor from which pellets fall directly to the burner gets damaged,
the reserve will be switched off automatically. This function is convenient in cases when you
need to control another external conveyor that supplies (feeds) pellets from a larger distance to
a pellet bin at the boiler from which the main external conveyor draws pellets to supply them
directly to the burner. Caution - the other external conveyor must always be controlled with an
additional level sensor (level meter) that will maintain the level of pellets in the pellet bin at the
boiler. This is a similar function to S6 = 9, but with a higher degree of safety.
k) S6 = 11….. Reserve function for controlling boiler exhaust fan for SP(X) boiler types when the
function for automatic start after wood is burnt out is activated. This function ensures that boiler
exhaust fan is running only during wood burning after the wood is burnt out. When the burner is
run on pellets, the boiler exhaust fan remains switched off. This function is used if you do not need
or want to use the boiler exhaust fan while the burner is running. Install the AD02 module under
the instrument hood of the boiler and connect it electrically between the boiler terminal board and
the extraction fan, see the wiring diagram.
WARNING – this is not a standard setting for SP(X) boilers with the function of automatic
start
(AUTOSTART – S34 = 1 or S34 = 2) after wood is burnt out (standard setting is S6 = 4).
EN
l) S6 = 12…..Reserve function for direct control of pump in the boiler circuit from the burner
regulation (boiler terminal board). This function controls the pump in the boiler circuit without
using AD02 or AD03 modules. This is applicable only for boilers that do not allow heating with
wood (not even in emergency situations). E.g. D14P, P14, D21P, P21, D25P, P25, D80P, P80,
DxxPX, PXxx. Pump output must be switched to reserve R on the boiler terminal board and the
TK sensor must be installed before this function can be activated. After activation, S37, S38, S39,
S40 temperature parameters must be checked and configured.
m) S6 = 13…..Reserve function is the reverse output function for controlling the pump in
the boiler circuit from the burner regulation (output cable from boiler with a connector – white
inside) via AD02 or AD03 modules. This function controls the pump in the boiler circuit using
AD02 or AD03 modules ranged into a set with pump thermostat installed into the boiler panel.
This method of pump controlling can be used for any ATMOS pellet boiler, and is therefore
recommended. AD02 or AD03 modules must be inserted and connected under the boiler hood
and the TK sensor must be installed before this function can be activated. After activation, S37,
S38, S39, S40 temperature parameters must be checked and configured.
n) S6 = 14….. Reserve function for direct control of solar heating pump from the burner regulation
(boiler terminal board). This function control solar pump when automatic sensor switching function
is activated (S15=3), where the boiler is connected with accumulation tank equipped with solar
exchanger and collectors. The system requires TV, TK, TS and solar sensors to be connected to the
TSV solar panel. This function never uses AD02 or AD03 modules.
After activation, S26, S27, S28, S29, S30, S31, S32, S33 temperature parameters must be checked
and configured.
This function is specially designed for boilers: D14P, P14, D15P, P15, D20P, P20, D21P, P21,
D25P and P25

CAUTION - the direct controlling function of solar heating from pellet burner cannot be
used for SP(X) boilers and boilers with burner built into the upper doors. This function also
cannot be used when the pump is simultaneously controlled in the boiler circuit from the
burner regulation (TK sensor cannot be simultaneously in boiler and accumulation tank)
o) S6 = 15….. Reserve function for the compressor control during the function for automatic
burner cleaning using compressed air. Power element designed for switching and powering the
compressor (e.g. contactor) must be connected between reserve output R and the compressor. This
function is connected with S6(14), S41, S42, S43, S44, S45, S46, S47 parameter, which must be
checked and configured.
p) S6 = 16….. Reserve function for controlling el.fan during the function for automatic burner
cleaning using compressed air. This function is connected with S6 (14), S41, S42, S43, S44, S45,
S46, S47 parameter, which must be checked and configured.
Special function for turning on reserve output R according to the temperature of a concrete
sensor:
a) e.g. function: TS>……. means that if the TS sensor temperature is higher then the set value in
S48 parameter – Temperature A, reserve output R will be activated
b) e.g. function: TS<……. means that if the TS sensor temperature is higher then the set value in
S48 parameter – Temperature A, reserve output R will be deactivated
c) e.g. function: TS,TV>……. means that if the TS and TV sensor temperature is higher at the
same time then the set value in S48 parameter – Temperature A and S50 – Temperature B, reserve
output R will be activated (Temperature A = first position (TS), Temperature B = second position
(Tv)).
d) e.g. function TS,TK<……. means that if the TS and TK sensor temperature is higher at the
same time then the set value in S48 parameter – Temperature A and S50 – Temperature B, reserve
output R will be deactivated (Temperature A = first position (TS), Temperature B = second position
(Tk)).

• Parameter S14 – characterizes the second reserve R2 - additional output - function … (12)
The second reserve R2 is used for controlling the pump in boiler circuit
CAUTION – In the standard setting when parameter S1 is set to 2, you can connect to the
reserve
A (approx. 566 VA).
In the setting when parameter S1 is set to 4, which means that at the start both the ignition
spirals are activated simultaneously, you can connect to the reserve
nal an applian¬ce with the maximum current of 0.29 A (approx. 67 VA).

b) S14 = 2….. If any fault occurs in the burner and the burner is shut down, the reserve relay will
be opened and the reserve output will not be energized. Thanks to this a signal can be sent to an
electrically backed up AB01 ATMOS GSM module controller that will send information that there
is a system fault or the system is not energized. This is the opposite logic (to S14 = 1), which
means that during normal operation the reserve is energized.
c)
S14 = 3…… The reserve function as the output function for the burner fan, when the
reserve output is closed, is energized always when the burner fan is running (fan mode only
100 % or OFF). This function is applied if you want the boiler fan or extraction fan in the chimney
to run together with the burner fan. This function is designed for direct control of an fan directly
from the burner (e.g.
d) S14 = 4…… The reserve function as the reversed function of the output for the burner fan,
when the reserve output is off, is not energized always when the burner fan is running. This
function is always activated if you connect the A25 burner with the AS25 set containing the
AD02 or AD03 module, which in this case controls the extraction fan of the boiler. Install the
AD02 or AD03 module under the instrument hood of the boiler and connect it electrically
between the boiler terminal board and the extraction fan, see the wiring diagram.
This setting and connection with AD02 or AD03 module and special connector (jumper to main
switch) is standardly used for SP(X) boilers with the function for automatic start after wood
is burnt out activated (AUTOSTART – S34 = 1 or S34 = 2). Boiler exhaust fan is running
simultaneously with the pellet burner during the AUTOSTART function.

e) S14 = 5…… Reserve function as the output function for the Z1 ignition spiral when the reserve
copies the run of the ignition spiral.
f) S14 = 6….. Cleaning function of the combustion chamber or grill (flap). If the burner is in the
normal START, RUN and STOP mode, the output is not energized. The output is only energized
for the limited time T11, which continues immediately after the expiration of time T5 in the
STOP mode. It is not used with the A25 burner.
g) S14 = 7….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The
reserve output work independently of the condition of the actual output for the external worm
conveyor. This means that if the standard output for the external conveyor gets damaged, the
reserve will work independently in accordance with the same program, and therefore it can be
used as a replacement for the damaged output.
h) S14 = 8….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The
reserve works in dependence on the status of the actual output for the external worm conveyor.
This means that if the output for the external conveyor gets damaged, the reserve will be switched
off automatically. This function is suitable in situations when you need to control another external
conveyor that supplies (feeds) pellets from a larger distance to the main conveyor from which the
pellets fall directly to the burner.

but runs permanently both during the drawing of the ignition amount and during both the
times T4 and T6. Thus, the other external conveyor runs continuously and works independently
of the status of the actual output for the external worm conveyor. This means that if the output
to the main external conveyor from which pellets directly fall to the burner gets damaged, the
reserve will keep working independently. This function can be used in cases when you need to
control another external conveyor that supplies (feeds) pellets from a larger distance to a pellet
bin at the boiler from which the main external conveyor draws pellets to supply them directly to
the burner. Caution - the other external conveyor must always be controlled with an additional
level sensor (level meter) that will maintain the level of pellets in the pellet bin at the boiler.

both the times T4 and T6. Thus, the other external conveyor runs continuously, but it works in
dependence on the status of the actual output for the external worm conveyor. This means that if
the output for the external conveyor from which pellets fall directly to the burner gets damaged,
the reserve will be switched off automatically. This function is convenient in cases when you
need to control another external conveyor that supplies (feeds) pellets from a larger distance to
a pellet bin at the boiler from which the main external conveyor draws pellets to supply them
directly to the burner. Caution - the other external conveyor must always be controlled with an
additional level sensor (level meter) that will maintain the level of pellets in the pellet bin at the
boiler. This is a similar function to S6 = 9, but with a higher degree of safety.
EN
k) S14 = 11….. Reserve function for controlling boiler exhaust fan for SP(X) boiler types when the
function for automatic start after wood is burnt out is activated. This function ensures that boiler
exhaust fan is running only during wood burning after the wood is burnt out. When the burner is
run on pellets, the boiler exhaust fan remains switched off. This function is used if you do not need
or want to use the boiler exhaust fan while the burner is running. Install the AD02 module under
the instrument hood of the boiler and connect it electrically between the boiler terminal board and
the extraction fan, see the wiring diagram.
WARNING – this is not a standard setting for SP(X) boilers with the function of automatic
start (AUTOSTART – S34 = 1 or S34 = 2) after wood is burnt out (standard setting is
S6 = 4).
l) S14 = 12…..Reserve function for direct control of pump in the boiler circuit from the burner
regulation (boiler terminal board). This function controls the pump in the boiler circuit without
using AD02 or AD03 modules. This is applicable only for boilers that do not allow heating with
wood (not even in emergency situations). E.g. D14P, P14, D21P, P21, D25P, P25, D80P, P80,
DxxPX, PXxx. Pump output must be switched to reserve R2 on the boiler terminal board and the
TK sensor must be installed before this function can be activated. After activation, S37, S38, S39,
S40 temperature parameters must be checked and configured.
m) S14 = 13…..Reserve function is the reverse output function for controlling the pump in
the boiler circuit from the burner regulation (output cable from boiler with a connector – white
inside) via AD02 or AD03 modules. This function controls the pump in the boiler circuit using
AD02 or AD03 modules ranged into a set with pump thermostat installed into the boiler panel.

Operation and Maintenance Manual - EN
This method of pump controlling can be used for any ATMOS pellet boiler, and is therefore
recommended. AD02 or AD03 modules must be inserted and connected under the boiler hood
and the TK sensor must be installed before this function can be activated. After activation, S37,
S38, S39, S40 temperature parameters must be checked and configured.
n) S14 = 14….. Reserve function for direct control of solar heating pump from the burner regulation
(boiler terminal board). This function control solar pump when automatic sensor switching function
is activated (S15 = 3), where the boiler is connected with accumulation tank equipped with solar
exchanger and collectors. The system requires TV, TK, TS and solar sensors to be connected to the
TSV solar panel. This function never uses AD02 or AD03 modules.
After activation, S26, S27, S28, S29, S30, S31, S32, S33 temperature parameters must be checked
and configured.
This function is specially designed for boilers: D14P, P14, D15P, P15, D20P, P20, D21P, P21,
D25P and P25
CAUTION - the direct controlling function of solar heating from pellet burner cannot be
used for SP(X) boilers and boilers with burner built into the upper doors. This function also
cannot be used when the pump is simultaneously controlled in the boiler circuit from the
burner regulation (TK sensor cannot be simultaneously in boiler and accumulation tank)
o) S14 = 15….. Reserve function for the compressor control during the function for automatic
burner cleaning using compressed air. Power element designed for switching and powering the
compressor (e.g. contactor) must be connected between reserve output R2 and the compressor.
This function is connected with S6(14), S41, S42, S43, S44, S45, S46, S47 parameter, which must
be checked and configured.

Special function for turning on reserve output R2 according to the temperature of a concrete
sensor:
a) e.g. function: TS>… means that if the TS sensor temperature is higher then the set value in S52
parameter – Temperature C, reserve output R2 will be activated
b) e.g. function: TS<… means that if the TS sensor temperature is higher then the set value in
S52 parameter – Temperature C, reserve output R2 will be deactivated
c) e.g. function: TS, TV>… means that if the TS and TV sensor temperature is higher at the same
time then the set value in S52 parameter – Temperature C and S54 – Temperature D, reserve output
R2 will be activated (Temperature C = first position (TS), Temperature D = second position (Tv)).

• Parameter S15 – Operation function of the burner by the two temperatures in the accumulation
tank …(1)
a) S15 = 1… The function is off, the burner works based on the thermoregulator on the boiler panel
b) S15 = 2 …. The function is activated and the pellet burner works based on the two temperatures
(sensors) in the accumulation tank – TV and TS (recommended tank volume: 1000 l).
The temperature of the bottom sensor (TS) is the temperature at which the burner is switched off
and the fuel burns out.
The temperature of the top sensor (TV) is the temperature at which the burner is switched on again.
The burner screen displays the TV and TS temperatures.
EN
c) S15 = 3 …. The function is activated and the pellet burner works based on the two temperatures
(sensors) in the accumulation tank – TV and TS (recommended tank volume: 1000 l).
The temperature of the top sensor (TV) is the temperature at which the burner is switched on again.
The temperature of the bottom sensor (TS or TK) is the temperature at which the burner is stopped.
Whether the burner is switched off based on the TS or TK sensor is decided by the temperature of
the solar panel (TSV) and the temperature in the lower part of the accumulation tank (TS), where a
solar exchange is built-in. If the solar panel can efficiently heat up water in the accumulation tank,
the burner is turned off based on the TK sensor, so that the tank can store energy from the sun.
If the energy delivered from the solar collector drops below a certain limit (temperature), the
deactivation logic of the burner is automatically switched back to be based on the TS sensor (S26
= 1).
However, it is possible to set that the switching may only occur after a certain period of time
(S29 = 2nd digit means the length of delay between switches, in hours). Another variant is to have
the burner work permanently based on the TV and TK temperatures (S26 = 0).
d) S15 = 4 …. The function is off and the burner works based on the TK temperature, protected
by the thermoregulators on the boiler panel. After this function is activated, we need to check and
possibly setup its temperature parameters S18 and S19.
CAUTION - if S15 = 2 not possible to set S6 = 14 a S14 = 14. Je-li S15 = 3 not possible
to setS6 = 11, S14 = 11, S6 = 12, S14 = 12, S6 = 13, S14 = 13. Je-li S15 = 1, S15 = 4 not

• Parameter S16 - Temperature of the top sensor (TV) at which the burner is started….. (60 °C)
It is the minimum temperature of water that can be reasonably utilized in the heating system.
• Parameter S17 - The temperature of the bottom sensor ((TS, or TK for S15 = 3)) at which the
burner is stopped….. (75 °C)
It is the maximum temperature of water that corresponds to requirements of the heated building
and the designed heat exchangers in the system (radiators and floor heating).
EN
CAUTION – Do not set this value too high to avoid disconnection of the safety thermostat on
the boiler. Always set the control thermostat on the boiler to the maximum value (95 °C). If
the control thermostat on the boiler intervenes before the burner is switched off by the signal of
the TS sensor in the bottom part of the accumulation tank, the system probably finds itself in the
state of hydraulic imbalance and you should check and adjust it. You can e.g. throttle the shortcut
in the boiler circuit or the return line from the heating system towards the accumulation tank.
• Parameter S18 – describes the required temperature of boiler TK, which the burner is switched
off at if S15 = 4… (85 °C)
• Parameter S19
- difference between TK temperature (for re-starting the burner) for S15 = 4…(5 K)
• Parameter S24 – maximum flue gas temperature... (250 °C)
If you connect a flue gas temperature sensor (TS) to the burner and in a mode of the burner this
limit value is exceeded, a warning message will appear on the display. It will notify the operator of the
necessity to clean the heat exchanger of the boiler or the installer of the necessity to reduce the burner
power to avoid unnecessary wasting of fuel. The operation of the burner is not limited by this
message in any way and to clear the message you can just switch off and on the main switch on the
boiler.

Parameter S26
TK sensor, when S15 = 3. Connection of the boiler with a tank equipped with a solar exchanger… (1)
– is the function for defining the logic of deactivating the burner based on the TS or
a) S26 = 0…. The burner permanently works based on the upper TV sensor (activation temperature)
and via the TK sensor (deactivation temperature). The lower part of the tank permanently has
enough room for energy from the solar collector (TS sensor)
b) S26 = 1… the burner permanently works based on the upper TV sensor (activation temperature)
and the configured logic automatically takes care of switching between the middle TK sensor and
lower TS sensor. Whether the burner is deactivated based on TS or TK is decided based on the
temperature on the solar panel (TSV) and the temperature on the lower part of the accumulation
tank (TS), where the solar exchanger is located. If the solar panel can efficiently heat up water in
the accumulation tank, the burner is turned off based on the TK sensor, so that the tank can store
energy from the sun.
• Parameter S17 - activation difference of function S26 = 1… (10 K)
If the temperature on the solar panel (TSV) exceeds the temperature in the lower part of the tank
by the activation difference, the boiler deactivation function will be switched from the bottom TS
sensor to the middle TK sensor.
If a function for solar panel pump control is activated directly from the boiler regulation (S6 = 14
or S14=4), the same logic will be used to activate the solar pump.
36-EN

Operation and Maintenance Manual - EN
• Parameter S28 – deactivation difference of function S26 = 1… (3 K)
If the temperature on the solar panel (TSV) exceeds the temperature in the lower part of the tank
by the deactivation difference, the boiler deactivation function will be switched from the middle
TK sensor to the bottom TS sensor.
If a function for solar panel pump control is activated directly from the boiler regulation (S6 = 14
or S14 = 4), the same logic will be used to activate the solar pump.
• Parameter S29 – is the function for delaying the automatic switching from the TK sensor back to
the TS sensor for controlling the burner based on two temperatures (sensors, S15 = 3)... (0 hours)
This function will cause the function for deactivating the burner to be switched from the middle
TK sensor to the bottom TS sensor after the time listed in parameter S29 passes, if the temperature
on the solar panel TSV is lower or greater only by the deactivation difference (Parameter S28) than
the temperature in the lower part of the tank where the solar exchange is located.
The set value means the number of hours, e.g.: S29 = 2 means a switch delay of 2 hours.
• Parameter S30 – is the function of the minimal operating time of the solar pump when the
conditions for its activation and then deactivation are met (function S15 = 3)… (3 min)
The set value means the number of minutes, e.g.: S30 = 3 means 3 minutes

• Parameter S31 – characterizes the required temperature TS in the lower part of the accumulation
tank where the solar exchanger is located, during the function of charging the accumulation tank
by the solar collector. (function S15 = 3)… (75 °C)
Once it is reached, the solar pump will be turned off.
• Parameter S32 – characterizes the maximum temperature TV in the accumulation tank during the
function of charging the accumulation tank by the solar collector (function S15 = 3)… (100 °C)
The solar pump will be turned off if it is exceeded.
• Parameter S33 – characterizes the maximum temperature TSV of the solar collector, for which
the solar pump will still remain in operation (function S15 = 3)… (115 °C)
The solar pump will be turned off if it is exceeded.
• Parameter S34 – is the function of automatically starting the pellet burner (AUTOSTART) after
the wood burns out. The function is specially created for SP(X) burners, however it may also be
used for two separate boilers… (0)
a) S34 = 0…. The automatic start function is off
b) S34 = 1…. The automatic start function is on. The pellet burner will be turned on when the
temperature of exhausts TSV drops below the set value (S36 = 80), e.g. below 80 °C
c) S34 = 2…. The automatic start function is on. The pellet burner will be turned on when two
conditions are met:
- the temperature of the boiler TK drops below the set value (S35 = 75), e.g. below 75 °C
- the temperature of exhausts TSV drops below the set value (S36 = 80), e.g. below 80 °C

Operation and Maintenance Manual - EN
If the function (parameter S34) is turned on in the boiler, the following practice is used for
boilers SP(X):
If the boiler is burning out but the wood container still contains enough wood, we may directly
switch the boiler switch from wood to pellets.
The pellet burner will perform a DIAGNOSTIC which will be used to ascertain the current status
of the boiler (temperature of exhausts, temperature of the boiler, temperature in the accumulation
tank)
If the conditions for immediate start of the burner are not met (see above), the burner will remain
EN
on standby, where the flue exhaust fan will remain in operation (if set) so that the wood can
properly finish burning (S6 = 4). AUTOSTART will start flashing on the burner screen.
If the AUTOSTART sign flashes slowly, the conditions set by the function (S34 = 1 or S34 = 2)
are not met.
If the AUTOSTART sign flashes quickly, the previous conditions are met, but the conditions set
by function (S15 = 2) are not, which means that the temperature on the accumulation tank did not
drop below the value set by S16 or the regulation thermoregulator on the boiler is not activated, i.e.
the end switch is not pressed (a star is not displayed on the boiler screen near the thermoregulator
symbol)
If all the conditions are met, the burner will start automatically.
INFO – In case of an electric outage, the burner will perform a DIAGNOSTIC and, if all
conditions are met, will burn out and return to normal operation. Otherwise it will await the
fulfillment of previous conditions (drop of exhaust and water temperature).
If we want to use wood to heat up the boiler, it suffices to place the switch on the wood
position. However, it is better to first keep the switch on the „0“ position for 10 - 15 minutes
so that the burner can properly burn out. This is an ideal time to prepare the fuel for stoking.
WARNING – SP(X) boilers do not allow you to control the solar heating function directly
from the pellet burner. Additionally the TK and TSV sensors are used for measuring the
temperature of the boiler and exhausts during this function.
• Parameter S35 – characterizes the limit (max.) temperature of the boiler TK, during which the
burner will automatically start during the AUTOSTART function (S34 = 2)… (75 °C)
• Parameter S36 – characterizes the limit (max.) temperature of the exhausts TSV, during which the
burner will automatically start during the AUTOSTART function (S34 = 2)… (80 °C)
WARNING – after placing the exhaust sensor TSV on a side of the burner flue pipe, the
TSV temperature is not the exact temperature of the exhausts but the difference temperature
for the automatic start function. If we want to place the exhaust sensor directly on or into the
flue pipe to measure the exhaust temperature precisely, it is necessary to always use a sensor
with a higher heat resistance of up to 400 °C.
• Parameter S37 – characterizes the requires temperature of the boiler TK during which the pump in
the boiler circuit will be activated. This will only occur if the required temperature is reached and
the boiler is in OPERATION or burn-out mode (S14=13 with modules AD02 or AD03)… (75 °C)

pump in the boiler circuit will be activated (S14 = 13 with modules AD02 or AD03)… (93 °C)
Activation will be carried out regardless of special functions of the burner (function S40). The
function works based on the deactivation difference specified in parameter S38.
• Parameter S40 – is the function for after-running of the pump in the boiler circuit used based on

pellet burner burns out is off (after the time specified in parameter T5 runs out). The pump will
be switched off after the temperature of the boiler TK drops (S38, S39). Designated for ceramic
boilers with a large momentum (with the option of stoking with wood).

19 = 9 - number of cycles)
If the parameter S41 = 0 or 10, the function is turned off.
• Parameter S42 – is the function for automatic cleaning of the burner by compressed air after a
certain period of operation. On the subsequent termination of a work cycle (burnout), the burner
mouth will be cleaned. The function utilizes both reserve outputs (S16 = 16, S14 = 15)… (4 hours)
After the time S42 runs out the pellet burner burns out and cleans. AUTO STOP will be shows on
the burner screen.
The set value represents the actual time in hours.
• Parameter S43 – is the function for automatic cleaning of the burner by compressed air after
a certain period of operation. After the set period elapses, the burner will immediately stop, be

• Parameter S67 - characterizes function of R5 reserve output similar with S6 and S14 parameters
with instaled AC07X-C additional module. Primary is this reserve used to control air pump for
pellet burner pneumatic ash cleaning system.... (15).
Function is also for DxxPX (PXxx) boilers, burner profile A25PX (A25PX pneu)
if:
a) S67 = 1…. If any fault occurs in the burner and the burner is shut down, the reserve relay will
be closed and the reserve output will be energized. Thanks to this you can start a spare source
of energy for heating of the building as e.g. a gas, electric or oil boiler.
EN
b) S67 = 2….. If any fault occurs in the burner and the burner is shut down, the reserve relay will
be opened and the reserve output will not be energized. Thanks to this a signal can be sent to
an electrically backed up AB01 ATMOS GSM module controller that will send information that
there is a system fault or the system is not energized. This is the opposite logic (to S6 = 1), which
means that during normal operation the reserve is energized.
c) S67 = 4…… The reserve function as the reversed function of the output for the burner fan,
when the reserve output is off, is not energized always when the burner fan is running. This
function is always activated if you connect the A25 burner with the AS25 set containing the
AD02 or AD03 module, which in this case controls the extraction fan of the boiler. Install the
AD02 or AD03 module under the instrument hood of the boiler and connect it electrically
between the boiler terminal board and the extraction fan, see the wiring diagram.
This setting and connection with AD02 or AD03 module and special connector (jumper to main
switch) is standardly used for DCxxSP boilers with the function for automatic start after
wood is burnt out activated (AUTOSTART – S34 = 1 or S34 = 2). Boiler exhaust fan is running simultaneously with the pellet burner during the AUTOSTART function.
d S67 = 7….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The
reserve output work independently of the condition of the actual output for the external worm
conveyor. This means that if the standard output for the external conveyor gets damaged, the reserve will work independently in accordance with the same program, and therefore it can be used
as a replacement for the damaged output.
e) S67 = 8….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The
reserve works in dependence on the status of the actual output for the external worm conveyor.

This means that if the output for the external conveyor gets damaged, the reserve will be switched
off automatically. This function is suitable in situations when you need to control another external
conveyor that supplies (feeds) pellets from a larger distance to the main conveyor from which the
pellets fall directly to the burner.
f) S67 = 15….. Reserve function for the compressor control during the function for automatic
burner cleaning using compressed air. Power element designed for switching and powering the
compressor (e.g. contactor) must be connected between reserve output R5 and the compressor.

b) e.g. function: TS<……. means that if the TS sensor temperature is higher then the set value in
S48 parameter – Temperature A, reserve output R5 will be deactivated
c) e.g. function: TS,TV>……. means that if the TS and TV sensor temperature is higher at the
same time then the set value in S48 parameter – Temperature A and S50 – Temperature B, reserve
output R5 will be activated (Temperature A = first position (TS), Temperature B = second position
(Tv)).

• Parameter S68 - characterizes function of R6 reserve output similar with S6 and S14 parameters
with instaled AC07X-C additional module. Primary is this reserve used to control electic valve for
pellet burner pneumatic ash cleaning system....... (16).
Function is also for DxxPX (PXxx) boilers, burner profile A25PX (A25PX pneu)
if:
a) S68 = 1…. If any fault occurs in the burner and the burner is shut down, the reserve relay will
be closed and the reserve output will be energized. Thanks to this you can start a spare source
of energy for heating of the building as e.g. a gas, electric or oil boiler.
b)
S68 = 2….. If any fault occurs in the burner and the burner is shut down, the reserve relay will
be opened and the reserve output will not be energized. Thanks to this a signal can be sent to an
electrically backed up AB01 ATMOS GSM module controller that will send information that there
is a system fault or the system is not energized. This is the opposite logic (to S14 = 1), which
means that during normal operation the reserve is energized.
c) S68 = 3…… The reserve function as the output function for the burner fan, when the re-
serve output is closed, is energized always when the burner fan is running (fan mode only
100 % or OFF). This function is applied if you want the boiler fan or extraction fan in the chimney
to run together with the burner fan. This function is designed for direct control of an fan directly
from the burner (e.g. DxxPX, PXxx).
EN
d) S68 = 9….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor, but with the difference that it does not
cycle, but runs permanently both during the drawing of the ignition amount and during both
the times T4 and T6. Thus, the other external conveyor runs continuously and works indepen-
dently of the status of the actual output for the external worm conveyor. This means that if the
output to the main external conveyor from which pellets directly fall to the burner gets damaged,
the reserve will keep working independently. This function can be used in cases when you need
to control another external conveyor that supplies (feeds) pellets from a larger distance to a pel-
let bin at the boiler from which the main external conveyor draws pellets to supply them directly
to the burner. Caution - the other external conveyor must always be controlled with an additional
level sensor (level meter) that will maintain the level of pellets in the pellet bin at the boiler.
e) S68 = 10….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor, but with the difference that it does not
cycle, but runs permanently both during the drawing of the ignition amount and during both
the times T4 and T6. Thus, the other external conveyor runs continuously, but it works in de-
pendence on the status of the actual output for the external worm conveyor. This means that if the
output for the external conveyor from which pellets fall directly to the burner gets damaged, the
reserve will be switched off automatically. This function is convenient in cases when you need to
control another external conveyor that supplies (feeds) pellets from a larger distance to a pellet
bin at the boiler from which the main external conveyor draws pellets to supply them directly to
the burner. Caution - the other external conveyor must always be controlled with an additional
level sensor (level meter) that will maintain the level of pellets in the pellet bin at the boiler. This
is a similar function to S6 = 9, but with a higher degree of safety.

f) S68 = 11….. Reserve function for controlling boiler exhaust fan for DCxxSP(X), CxxSP,
ACxxSP boiler types when the function for automatic start after wood is burnt out is activated.
This function ensures that boiler exhaust fan is running only during wood burning after the wood
is burnt out. When the burner is run on pellets, the boiler exhaust fan remains switched off. This
function is used if you do not need or want to use the boiler exhaust fan while the burner is running. Install the AD02 module under the instrument hood of the boiler and connect it electrically
between the boiler terminal board and the extraction fan, see the wiring diagram.
EN
WARNING – this is not a standard setting for DCxxSP(X), CxxSP, ACxxSP boilers with
the function of automatic start

g) S68 = 12…..Reserve function for direct control of pump in the boiler circuit from the burner
regulation (boiler terminal board). This function controls the pump in the boiler circuit without
using AD02 or AD03 modules. This is applicable only for boilers that do not allow heating with
wood (not even in emergency situations). E.g. D14P, P14, D21P, P21, D25P, P25, DxxPX, PXxx.
Pump output must be switched to reserve R5 on the boiler terminal board and the TK sensor must
be installed before this function can be activated. After activation, S37, S38, S39, S40 temperature
parameters must be checked and configured.
h) S68 = 13…..Reserve function is the reverse output function for controlling the pump in
the boiler circuit from the burner regulation (output cable from boiler with a connector – white
inside) via AD02 or AD03 modules. This function controls the pump in the boiler circuit using
AD02 or AD03 modules ranged into a set with pump thermostat installed into the boiler panel.
This method of pump controlling can be used for any ATMOS pellet boiler, and is therefore
recommended. AD02 or AD03 modules must be inserted and connected under the boiler hood
and the TK sensor must be installed before this function can be activated. After activation, S37,
S38, S39, S40 temperature parameters must be checked and configured.
i) S68 = 14….. Reserve function for direct control of solar heating pump from the burner regulation (boiler terminal board). This function control solar pump when automatic sensor switching function is activated (S15 = 3), where the boiler is connected with accumulation tank equipped with
solar exchanger and collectors. The system requires TV, TK, TS and solar sensors to be connected
to the TSV solar panel. This function never uses AD02 or AD03 modules.
After activation, S26, S27, S28, S29, S30, S31, S32, S33 temperature parameters must be checked
and configured.
This function is specially designed for boilers: D14P, P14, D15P, P15, D20P, P20, D21P, P21,
D25P and P25
CAUTION - the direct controlling function of solar heating from pellet burner cannot be

EN
Short explanation:
This always depends on whether the burner regulation function based on two temperatures on the
accumulation tank is on or off, and whether the automatic start function after wood burns out is
activated.
The default settings are S15 = 1 and S34 = 0, which means that the function for controlling the
burner by two sensors is deactivated and the AUTOSTART function for DCxxSP(X)/(EP), CxxSP,
KCxxSP burns is also off. The burner is only controlled by thermoregulators on the boiler panel.
The customer may connect the exhaust temperature sensors TS and TSV and the water temperature
sensors TV and TK to the burner so that they only serve as information.
If we set S15 = 2, the function for regulation by two temperatures on the tank is activated and
so we connect the water tempearture sensor in the lower part of the tank TS and the water
temperature sensor in the upper part of the tank TV to the clamps of the burner connector.
If we set S15 = 3, the function for regulation by two temperatures on the tank is also activated,
simultaneously with the solar functions. It is thus also necessary to connect the TK sensor
located in the middle of the accumulation tank between the TV and TS sensors and the TSV
solar collector sensor.
If we are going to use the AUTOSTART function for boilers DCxxSP (S34 = 1 or S34 = 2), we must
also connect the TK sensor as a boiler sensor and the TSV sensor as the exhaust temperature
sensor.
If we are going to control the pump in the boiler circuit (recommended S14 = 12 or S14 = 13),
we must always connect the TK sensor.

If you are not sure, proceed as follows:
- Check whether the worm conveyor is really working by plugging the conveyor connector directly
to a wall socket, if so
- Turn off and on the main switch of the boiler and watch the lighting and flashing symbols on the
display of the electronic unit. Each start over a particular symbol on the display means that the
element or function is in operation or should be.
Each symbol on the display characterizes one element or function of the burner.
EN
- Indicates operation of the external conveyor
-
Indicates connected control thermostat of the boiler
- Indicates connected ignition spiral 1
- Indicates connected ignition spiral 2
- Indicates the fan running at the starting or
operation speed
- Indicates connected reserve output R (bottom *)
- Indicates connected reserve output R2 (top *)
- Indicates that the photocell sees the flame
- If an error message related to the damage of a particular part on the burner appears immediately,
you should call the customer service to replace the damaged part
- If no error message appears, you must watch and compare the function of individual elements in
the burner by checking which symbol on the display is flashing or lighting up. This way you can
easily locate a possible defect within the burner (faulty part).
- If the burner or boiler is not energized, check the supply cable of the boiler or the cable between
the burner and the boiler
CAUTION - BEFORE OPERNING THE COVER TURN OFF THE MAIN SWITCH!
Checks of live parts may only be performed by a qualified person in accordance with
valid standards and laws.
Inspection procedure of the inner electric installation of the burner and boiler:
- Check whether the burner is energized
- Check whether the start signal is being sent to the burner - the control and safety thermostat
is connected - L2 - the symbol on the display is lit
- Check whether the supply phase - L1 - is flowing to the burner
- Check the fuses in the electronic board for the fan, conveyor and ignition spirals
- Check the terminal board for released contact
Check whether the ignition spiral at the start ignites (heats up) when the or symbol lights up
-
- Check the connection of the ignition spiral (supply wires)
- Check the connector of the supply cable of the burner for wrong connection - whether phase L1
(supply phase) is not interchanged with L2 (controlled phase) or reserve R, R2

If no problem has been found, reset the regulation AC07X by the RESTART command.
If the system is working, but you are not satisfied with its function, proceed as follows:
Check the quality of pellets
• Heating value - whether they are really pellets made of wood or whether something has been
added to them - crumble them and smell
• Colour - caking - white pellets do not cake, dark pellets or pellets with dark dots that contain bark
cake.
If the pneumatic cleaning does not manage to clean the burner combustion chamber sufficiently,
shorten the times defined by parameters S42 and S43. When the two hour time span for cleaning is
not sufficient, the pellets contain impurities that make it impossible to burn these pellets in a A85
burner (biological waste). Must be replaced.
• Dust in pellets - causes uneven operation of the burner and clogging of the burner hose
• Size - too small pellets - reduce the burner power (Ø 5 x 5 mm), long pellets do not fall freely to
the burner and clog the supply pipe.
Check the flue gas temperature
• It should be in the optimal range (130 ÷ 220 °С).
• If the temperature is too low, reduce the power of the burner (decrease parameter T4 and increase
T6) and reduce the quantity of combustion air or clean the boiler.
• If the temperature is too low, increase the power of the burner and quantity of combustion air
(increase parameter T4).
EN
Check the level of pellets in the burner mouth
•
If it is too low and the burner goes out, check the flue gas temperature (see above). Reduce the
quantity of combustion air or increase the quantity of supplied pellets - increase the power (increase
parameter T4).
• If the pellet level in the burner mouth is too high and the burner exhibits poor combustion - produces
smoke, increase the quantity of combustion air or reduce the quantity of supplied pellets - reduce the
power (decrease parameter T4).
At the start check how long it takes for combustion quality to improve - how long smoke is released
from the chimney
• If smoke is released from the chimney at the start for more than 5 minutes, extend the time of
gradual increase to the nominal power (parameter T10, e.g. increase by 5min). Be careful about
the setting of the air flap.
The burner regularly does not ignite at the first attempt, but always at the second one
• Extend the time for the supply of ignition fuel (parameter T1 e.g. by 10 s), extend time T2 for
ignition of pellets (e.g. to 15 minutes) or reduce the angle of the conveyor (max. 45°).
If after stopping of the burner and its burning out a lot of glowing unburnt pellets remain in the
combustion chamber (mouth) of the burner
•
Extend the rundown time of the fan - parameter T5 (e.g. extend the time by 5 minutes) - never shorten

18. Maintenance and cleaning of the burner
The system for burning wooden pellets is designed in such a way to require minimum maintenance.
The necessary degree of maintenance directly depends on the set power of the burner and quality of
used pellets.
CAUTION - Before starting repair or maintenance work during which you will handle
the burner always turn off the power supply with the main switch of the boiler or
EN
Regular removal of ashes:
Burning of wooden pellets leaves approximately 1 to 2 % of ashes. In practice you will gradually
find out how often the burner should be cleaned depending on the set power, intensity of heating and
quality of used fuel. Before the start of cleaning you must first shut down the burner and let the fuel
burn out, best by reducing the temperature on the control thermostat or by turning off the burner
switch on the boiler panel. The common interval of cleaning the burner mouth and boiler varies
in the range of 7 to 30 days (after burning of 300 to 1000 kg of high-quality pellets).
For this reason the basic version of ATMOS burner A85 is equipped with pneumatic cleaning
which cleanses the burner’s combustion chamber after every burn out or at regular intervals (factory
setting is 4 hours – parameter S42, S43). Thanks to pneumatic cleaning you can check or clean the
burner’s combustion chamber only once in a fortnight or a month.
Then remove ashes from the combustion space of the boiler and clean the heat exchanger of
the boiler (tube plate) as described in the boiler manual.
disconnect to supply cable of the burner with the connector!
CAUTION - Always put ashes in a closed vessel. During the removal of ashes and cleaning
of the combustion chamber use means of personal protection (gloves and protective goggles).
Annual maintenance
• At least once a year you must perform a complete check, maintenance and inspection of the
burner during which the burner must be removed from the boiler.
• During this maintenance remove and wipe the photocell that senses the flame.
• Thoroughly clean the space under the combustion chamber of the burner and behind the ignition
spiral. Disassemble the inlet pipe through which pellets fall to the burner and clean it.
• Dismount the covering metal sheet of the burner mouth attached with one screw and clean the
space under it where pellets fall and burn (scrape off dust and deposits). Clean the opening
through which the photocell sees the flame.
• Knock dust out of the flexible supply hose and visually check whether it is not perforated. In such
a case repair it or replace. On that occasion check the worm of the external conveyor by inspecting
58-EN
www.atmos.cz
Operation and Maintenance Manual - EN
it from the bottom where pellets fall into the flexible hose. Check whether is it not strangled by
some objects, e.g. wound strings, a piece of wood, etc. that are sometimes found in pellets.
• Then, assemble and seat everything in the boiler. Tighten all the connections.
• Finally, check the basic functions and safety of the electronic unit in the TESTING and
INFOR MATION submenus, see page 49 and 50. Check the function of the end switch and 95 °C
(55 °C for boilers DxxPX, PXxx) safety thermostat at the pellet inlet to the burner (contact of the
thermostat with the pipe), see page 10 and 11.
CAUTION - It is prohibited to do welding work on the equipment if the system is connected
to the electric mains and the electronic control unit is not removed. It might get damaged.
If the customer is not able to carry out the annual inspection and maintenance of the burner
by themselves, this service may be ordered from a service engineer. This service is subject
to a fee. Make a record of the annual maintenance and inspection in the operation manual
on page 64.
