2. GENERAL INFORMATION
The controller is a modern electronic device
designed to handling the work of the pellet
boiler using help of optical flame brightness
sensor. The device is compactly build, easy
to install.
It can control the work of central heating and
hot water circuits and also control the work
of 5 mixing heating circuits. The required
temperature of heating circuits can be set on
the basis of data obtained from the main
sensor. The possibility of cooperation with
room thermostats, separate for each heating
circuit is beneficial for maintaining
comfortable temperature in heating rooms.
Moreover, the device turns on the spare
boiler (gas or oil one)
The controller can cooperate with additional
steering panel located in living rooms and
additional modul of lambda λsensor.
Handling of the controller is easy and
intuitive. The controller can be used within
the household and in small industrial
buildings.

Pic. 3 auxiliary window displaying fuel level.
8.3 CONTROLLER START UP
After connecting the power the controller
shows the settings put before connecting the
electricity. If the controller has not operated
before –it will start up in „stand by” mode.
In this mode the screen is dimmed, actual
time and information: Boiler on is displayed.
In this mode protecting pumps against going
stale function is in operation. It is executed
by temporary switching them on. Therefore it
is advised to keep the electrical power to the
controller on when the boiler is not in use.
And the controller should be in “stand by”
mode. It is possible to start up the boiler
(pressing the encoder knob and selecting
„switch on”) or setting parameters of its
operation (MENU button) without connecting
it to the electrical power. After making sure
that fuel is in the silo, and the hatch is closed
–the boiler can be switched on.
8.4 BOILER TEMPERATURE
SETTING
The preset boiler temperature and preset
circuits temperature can be set in the menu
(Possible temperatures are restricted with
range of respective service parameters of the
controller).
Menu→Boiler settings →Preset boiler
temperature.
Menu→Mixer settings 1,2,3,4 →Preset
mixer temperature
8.5 FIRING UP
FIRING UP mode is for automatic firing up of
furnace in boiler. Total time of firing up
proces is dependand on controller’s settings
(feeder operation time, heater operation
time, etc.) and on boiler’s condition before
firing up. Parameters influencing firing up
process are in the menu:
Menu →Service settings →
Boiler settings →Firing up
In case of failed attempt of firing up the
furnace, another attempts are taken during
which amount of fuel (feeding time) is
reduced to 10% of first attempt’s dose.
Pic. 4 Signalling FIRING UP mode and numer
of attempt .
After three failed firing up attempts an alarm
Failed firing up attempt is reported. Boiler’s
operation is then stopped. It is not possible
to automatically continue boiler’s operation.
Service intervention is required. After finding
and solving the cause of firing up failure the
boiler should be fired up again.

8.6 WORK
Pic. 5 Main window view while operating.
The fan operates constantly –see Pic. 6. Fuel
feeder is engaged periodically. One period
consists of feeder operating time and pause
in feeding time.
Pic. 6 . Fan and feeder operation periods.
Parameters related to Operation mode are :
feeder operating time and Air flush intensity
located in:
Menu →Boiler settings →Output
modulation
and operation time period located in
Menu → Service settings →Boiler settings.
There are two regulation modes responsible
for stabilization of boiler preset temperature:
Menu → Boiler settings →Regulation
mode
Standard mode operation
If the boiler’s temperature reach preset one
then the controller switches of to
SUPERVISION mode.
Controller is equipped with boiler’s power
modulation mechanism –which allows for
gradual power reduction when approaching
the preset temperature.
There are three power levels:
Maximal power 100%
Medium power 50%
Minimum power 30%
Current power level is displayed on the
screen as 3 segmented indicato rat the left
side of boiler’s icon.
Pic. 7. Power level indicator in main window.
Each level can be allocated with seperate fuel
feeding times and Air flush intensity which
influence on actual boiler’s power level.
Power levels parameters are available in the
menu:
Menu →Boiler settings →Output
modulation
The controller regulates burner’s power with
which it operates depending on preset
temperature and defined hysteresis
Hysteresis H2 and Hysteresis H1 Pic. 8
Hystereses H1 and H2
It is possible to configure volumes H1 and H2
in such a way that modulation is done
without intermediate position. That means
switching from 100% to 30% with omission
of 50% power (right side of the picture).
Pic. 8 Hystereses H1 and H2 of power modulation

12
Operation in Fuzzy Logic mode
In Fuzzy Logic mode the controller
automatically regulates burner power to
allow boiler operation in such a way to
maintain its temperature on preset level. The
controller uses power levels defined in
Standard mode. In this mode the parameters
Hysteresis H2 and Hysteresis H1 do not have
to be set.
The Fuzzy Logic mode unlike the Standard
mode is not faulty in respect of failing to
reach the preset boiler temperature due to
incorrect adjustement of Hysteresis H2 and
Hysteresis H. It also allows for quicker reach
the preset temperature.
Attention: If the boiler operates
without heat buffer and controller is
switched into SUMMER mode than
Standard mode operation of the
controller is recommended.
After exceeding the preset temperaturę by 5
degrees C the controller switches into
SUPERVISION mode.
8.7 SUPERVISION
SUPERVISION mode is applicable either in
regulation in STANDARD and Fuzzy Logic
mode.
The controller switches into SUPERVISION
mode automatically without user’s
intervention: - in Standard regulation mode
–after reaching the boiler preset
temperature, - in Fuzzy Logic steering –after
exceeding boiler preset temperature by 5
degrees C.
In SUPERVISION mode the controller
oversees the furnace, keeping it from
burning off. To do so, the burner operates
with very low power, what together with
properly adjusted parameters do not cause
further increase in temperature. Burner’s
power in SUPERVISION mode and other
parameters of Supervision are grouped in
menu:
Menu → Service settings →Boiler
settings →Supervision
Parameters of SUPERVISION mode are to be
set in accordance to burner/boiler producer’s
recommendations. They should be so chosen
to prevent the furnace from burning off
during boiler’s pauses (the furnace should
not at the same fire up to too high a
temperature, because it will cause too high a
temperature of the boiler). Operation and
pause time of the feeder in SUPERVISION
mode is set using following parameters:
Feeding time SUPERVISION,Period time
SUPERVISION and Air flush intensity
SUPERVISION.
The parameters in this mode must
be so chosen as to make the boiler
temperature gradually decreasing.
Incorrect settings can cause boiler
overheating.
Maximum time of boiler’s operating in
supervision mode is defined in parameter
Supervision time.If after this time (in
Supervision mode) there is no need to
restart the boiler then the controller starts
the process of boiler’s burning off.
For setting Supervision time = 0 the
controller omits SUPERVISION mode
and goes directly to BURNING OFF.
8.8 BURNING OFF
In burning off mode the leftovers of pellet
are burnt and the boiler is prepared to pause
or deactivation.
All the parameters influencing burning off
process are grouped in menu:
Service settings →
Boiler settings →Burning off
The controller stops feeding fuel and makes
periodical blowings to burn off remnants of
fuel. After decrease of flame brightness or
maximum time of burning off expiration the
controller turns into PAUSE mode.
8.9 PAUSE
In PAUSE mode the boiler is being burnt off
and awaits the signal to start operation. The
following can be a signal to start operation:
Decrease of preset boiler temperature
below preset temperature diminished by
boiler hysteresis (Boiler hysteresis),

13
By boiler operation configuration with the
buffer decrease of top buffer temperature
below preset value (Temperature when
start buffer feeding).
8.10 GRID
Some boilers have an additional grate to
burn other fuels such as wood waste, etc. To
activate the grid, move the parameters
available in the:
Main menu →Boiler settings →Boiler
oper. mode
from "pellet" to "grid". In the grid mode fuel
feeder is turned off. The combustion process
is regulated by the fan. Fan power, when
working with grid, is set in:
Main menu →Boiler settings →Output
modulation > Fan power –grid
The values of parameters such as:
Main menu →Boiler settings →Prest
boiler temp
Main menu →Boiler settings →Output
modulation →Boiler histeresis
Main menu →Service settings →Burner
settings →Fuel detection time
are individually adjusted for the "grid". This
allows you to define different properties of
boiler operation for operation modes "grid"
and "pellets".
When using the grid an alarm "No fuel" can
appear. This alarm occurs when a
temperature drops below the value of the
parameter:
Main menu →Service settings > CH and
HUW settings →CH activation temp.
and then for a period of 10 minutes there
has been no growth.
8.11 HOT WATER SETTINGS
The controller regulates temperature of the
silo of Hot Water HW, providing that the
temperature sensor is connected. When the
sensor is disconnected –the information
about it is displayed in the main window. By
selecting:
Menu →HUW settings →HUW Pump
mode the user is able to:
Deactivate feeding the silo, parameter
Deactivated,
Setting HW priority, by parameter
Priority –then CH pump is
deactivated to feed the HW boiler
quicker,
Set simultaneous operation of CH and
HW pump with the parameter No
priority,
Activate function Summer.
8.12 HOT WATER TEMPERATURE
SETTINGS
Preset temperature HW is defined by
parameter:
Menu →HUW settings →Preset HUW
temperature
8.13 HYSTERESIS OF HOT WATER
FEEDER
Below temperature Preset temperature HW –
Silo hysteresis HW the HW pump will activate
to feed the HW silo .
By small hysteresis value HW pump
will activate faster after HW
temperature decrease.
8.14 SUMMER FUNCTION START UP
To activate SUMMER function which allows
feeding the silo during summer, without
necessity to activate CH installation and
mixers periods, it is required to set the Pump
operation mode HW for Summer.
Attention: when boiler operates
without heating buffer and the
controller is switched into SUMMER
mode, than Standard mode
operation is is recommended. point
8.6
It is not allowed to activate
function summer when HW pump is
disconnected or damaged.
Function SUMMER can be activated
automatically, on the basis of readings from
weather sensor. Use following parameters to
activate this function:
Menu → HUW settings → Auto. detection
SUMMER, Activating temp. SUMMER,
Deactivating temp. SUMMER

14
8.15 HOT WATER FEEDER
DISINFECTION
The controller can automatically, periodically
make HW silo warm up to 70 degrees C. It is
done to remove bacterial flora.
It is absolutely important to inform
all the inmates about activating the
disinfection function. There is a
danger of scalding with HW hot
water.
Once a week at night between Sunday and
Monday at 2 a.m. the controller increases
temperature of HW silo. After 10 minutes of
keeping the silo at 70 degrees C the HW
pump is deactivated and the silo returns to
its normal operation. It is not advisable to
activate disinfection function while the
service of HW is deactivated.
8.16 MIXER CIRCLE SETTINGS
Settings of first mixer circle are in the menu:
Menu →Mixer 1 settings
Settings for other mixers are in following
sections of the menu and are identical in
each cycle.
Mixer settings (without weather sensor) It
is required to set manually desired
temperature in mixer’s heating cycle using
parameter Preset mixer temperature,e.g. 50
degrees C. Such should be a value to provide
required room temperature. .
After connecting a room thermostat, value of
decline in preset mixer temperature from
thermostat should be set. (parameters mixer
room thermostat e.g. 5 degrees C. This value
should be chosen experimentally. A room
thermostat can be a traditional one or a
room panel ecoSTER200. After activating the
thermostat, mixer preset temperature will be
reduced. When this value is reduced
correctly then room temperature increase
will be stopped.
Mixer with weather sensor setting
(without room panel ecoSTER200) Set
parameter mixer weather control in position
on. Adjust weather curve according to point
8.16
Using parameter paralel curve movement set
required room temperature according to
formula:
Required room temperature = 20°C +
heating curve paralel movement.
Example.
To reach room temperature 25°C value of
heating curve movement must be set for
5°C. To reach room temperature 18°C value
of heating curve paralel movement must be
set for -2°C.
In this configuration a thermostat can be
connected. It will level inaccuracy of heating
curve adjustement in case when its value will
be too big. In such case value of decrease of
preset mixer room temperature from
thermostat should be set i.e. for 2°C.After
discontecting thermostat plugs preset mixer
cycle temperature will be reduced. By correct
adjustement of this reduction will stop
temperature increase of temperature in
heated room.
Mixer with weather sensor and room
panel ecoSTER200 settings
Set parameter Mixer weather control. In
position off.
Adjust weather curve according to point 8.16
Controller ecoSTER200 automatically moves
the heating curve depending on preset room
temperature. The controller relates
adjustements to 20 degrees C, i.e. for preset
room temperature = 22 degrees C the
controller will move heating curve by 2
degrees C, for preset room temperature = 18
degrees C the controller will move heating
curve by -2 degrees C. In some cases
described in point 8.16 it can be necessary to
adjust heating curve movement.

15
In this configuration room thermostat
ecoSTER is able to:
reduce temperature of heating cycle by a
constant value, when preset temperature in
a room will be reached. Similarly like it was
described in previous point (not
recommended), or
automatically, constantly correct heating
cycle temperature.
It is not recommended to use both these
possibilities at the same time.
Automatic correction of room temperaturę is
done according to formula:
Correction = (preset room temperature –
measured room temperature) x room
temperature factor / 10
Example.
Preset temperature in heating room (set in
ecoSTER200) = 22 degrees C. Measured
temperature in room (using ecoSTER200) =
20 degrees C. room temperature factor = 15
Preset mixer temperature will be increased
by (22 degrees C –20 degrees C) x 15/10 =
3 degrees C. Correct value of parameter
must be found room temperature factor.
Scope: 0…50. The bigger value of factor the
bigger correction of preset boiler
temperature factor. When set on value “0”
preset mixer temperature is not corrected.
Attention: setting too high value of room
temperature factor may cause cyclic room
temperature fluctuations.
8.17 WEATHER CONTROL
Depending on measured outside
temperature, automatically controlled can be
either preset boiler temperature and mixer
cycles temperatures. By correct adjustment
of heating curve temperature of heating
circuits is counted automatically depending
on value of external temperature. Thanks to
that by choosing proper heating curve for
given building, room temperature remains
approximately the same –no matter what
outside temperature.
Attention: in the proces of experimental
adjustement of proper heating curve it is
necessary to exlude influence of room
thermostat on controller work (irrespectively
if room thermostat is connected or not), by
adjusting parameter:
For mixer cycle: Mixer settings 1 –Mixer
room thermostrat = 0
In case of connected room panel
ecoSTER200 set additionally room
temperature factor = 0
Guidelines for correct heating curve settings:
Floor heating 0,2 –0,6
Radiator heating 1,0 –1,6
Buffer 1,8 - 4
Pic. 9 Heating curves.
Tips for choosing proper heating curve:
If by falling outer temperature room
temperature is increasing, then value of
chosen heating curve is too big,
If by decreasing outer temperature, room
temperature is also decreasing, then value of
chosen heating curve is too low,
If by frosty weather room temperature is
appropriate and in warmer time is too low –
it is recommended to increase parameter
heating curve parallel shift and then choose
lower heating curve.

16
If by frosty weather room temperature is too
low and in warmer time too high –it is
recommended to reduce parameter heating
curve parallel shift and choose higher heating
curve.
Buildings which are poorly isolated require
setting heating curve with higher values, and
for better isolated buildings heating curve
will have lower value.
Preset temperature, counted according to
heating curve can be decreased or increased
by controller when it goes beyond scope of
limits of temperatures for given cycle.
8.18 NIGHT DECREASE SETTINGS
DESCRIPTION
In the controller it is possible to set time
periods of silo temperature reduction,
heating cycles, hot water silo, and circular
pump.
Time periods allow setting temperature
reduction in given time period –i.e. at night
or when user leaves the heated room.
Thanks to it preset temperature can be
reduced automatically, without loss of
heating comfort by reducing fuel
consumption.
To activate time periods use parameter Night
reduction for given cycle and activate it.
Night reductions can be defined separately in
working days, Saturdays and Sundays.
Pic. 10 Window of time periods choosing.
It is needed to set the beginning and the end
of given time period and value with which
the preset temperature will be reduced.
Pic. 11 Time periods edition.
Below sample preset night temperature
reduction is presented.
Attention, defining time periods
during one day must be started at
00:00!
Pic. 12 Sample of defining time periods.
In this example from 00:00 to 06:00 the
controller will set preset silo temperature by
3 degrees C. Since 06:00 to 09:00 the
controller leaves preset silo temperature at
preset level (without reductions).Since 22:00
to 23:59 the controller will reduce preset silo
temperature by 3 degrees C.
Time period is omitted by setting
period reduction for value “0” even
if scope of hours is set in it
Reduction of preset silo temperature
from time period is signalled with
the letter „S” in main window of the
display.

8.19 CIRCULAR PUMP CONTROL
Attention: functionality of circular pump is
available only after connecting additional
module MX.03
Settings are in:
MENU →Night time decrease →Circular
pump.
oraz
Menu →Service settings → CH and HUW
settings
Settings of time control of circular pump are
analogical to settings of night reductions. In
defined time periods circular pump is
deactivated. In omitted periods the circular
pump is switched into position circular
operation time
Detailed settings are shown in point 0.
8.20 FUEL LEVEL CONFIGURATION
Fuel level indicator activating
To activate displaying fuel level following
parameters are to be set
Menu –Boiler setting –Fuel level –
alarm level
On value bigger than “0”, i.e. 10%
Twisting “TOUCH and PLAY” knob in main
window fuel level is displayed in main
window.
Tip: fuel level can also be seen in room panel
ecoSTER200 (room panel is not a standard
option of the controller).
Pic. 14 Auxiliary window with fuel level display.
Fuel level indicator service
Each time when fuel silo is filled to required
level it is necessary to press and keep the
knob in main window. Following info will
appear:
Pic. 15 Fuel level service.
After choosing and accepting „YES” fuel level
will be set for 100%. Attention: Fuel can be
refilled anytime, that means it is not needed
to wait till the silo is empty. However fuel
should be filled up to the level corresponding
to 100% and set the controller level by
pressing knob.
Description of activity
The controller measured fuel level on the
basis of its current consumption. Factory
settings will not always correspond to actual
fuel consumption , so to work correctly this
method needs level calibration by controller’s
user. No additional fuel sensors are required.
Calibration
Fill the silo to the level which corresponds to
full level of fuel, then set value of parameter:

18
Menu –Boiler settings –Fuel level –fuel
level calibration –fuel level 100%
In main window the indicator will be set on
100%. The calibration process is marked
with a pulsating fuel level indicator. The
indicator will pulsate until programming point
referring to minimum fuel level. Decreasing
level of fuel in the silo should be monitored
constantly. When fuel level reaches expected
minimum, parameter value should be set this
way:
Menu →Boiler settings →Fuel level →
Fuel level calibration →Fuel level 0%
8.21 COOPERATION WITH
ADDITIONAL FEEDER
After connecting additional B module the
controller can cooperate with low fuel level
sensor in silo. After activating sensor , for
auxiliary feeder operation time controller will
connect auxiliary feeder to refill basic fuel
level. This parameter can be found in:
Menu →Service settings →Burner
settings
8.22 INFORMATION
Menu information enables view to measured
temperatures and allows to check which of
devices are currently activated. Switching
between following screens is done by
twisting “TOUCH and PLAY” knob.
After connecting extension module
of mixers information about
auxiliary mixers are displayed
Writing „CAL” in information window
of mixer by position valve opening
level stands for active process of its
calibration. It is necessary to wait
until calibration of mixer valve
servomotor is completed. Then its
current state will be displayed.
8.23 MANUAL CONTROL
In the controller it is possible to manualy
activate devices like i.e. pumps, feeder
engine, or blower engine. It enables to check
if the device is operating correctly and if it is
connected properly.
Attention: Entering manual control
is possible only in STAND-BY mode,
when silo is switched off
Pic. 16. Manual control window wiev, when OFF –means
that the device is off, ON –activated.
Attention: long lasting activating of
fan, feeder or other device may
cause danger.

Pic. 17 Scheme with 4 way steering valve controlling central heating circuit2,where: 1 –boiler, 2 –
burner, 3 –controller, 4 –boiler temperature sensor, CT4, 5 –fumes temperature sensor, 6 –servomotor of
4 way valve, 7 –mixer cycle pump, 8 –mixer cycle temperature sensor, 9 –silo of hot water, 10 –hot
water pump, 11 –hot water sensor, 12 –weather temperature sensor CT4-P, 13 –room panel ecoSTER200
or standard room thermostat, 14 –return temperature sensor.
To improve water circulation in gravity cycle it is necessary to use large nominal profiles
DN of a pipe and 4 way valve, not to use large amount of knees and profile narrowings.
Use other rules referring to gravity installations. If return sensor is installed closely, it is
necessary to isolate it thermically from surroundings and improve thermal contact with
pipe. Preset silo temperature must be set so high to ensure thermal power for mixer cycle
when at the same time heating water returning to the silo.
