1Recommendations regarding
safety
Requirements concerning safety are
described in detail in individual chapters of
this manual. Apart from them, the following
requirements should in particular be
observed.
Before starting assembly, repairs or
maintenance, as well as during any
connection works, please make sure
that the mains power supply is
disconnected and that terminals and
electric wires are devoid of voltage.
After the regulator is turned off using
the keyboard, dangerous voltage still
can occur on its terminals.
The regulator cannot be used at
variance with its purpose.
Additional automatics which protect
the boiler, central heating (CH)
system, and domestic hot water
system against results of malfunction
of the regulator, or of errors in its
software, should be applied.
Choose the value of the programmed
parameters accordingly to the given
type of boiler and fuel, taking into
consideration all the operational
conditions of the system. Incorrect
selection of the parameters can cause
malfunction of the boiler (e.g.
overheating of the boiler, the flame
going back to the fuel feeder, etc.),
The regulator is intended for boiler
manufacturers. Before applying the
regulator, a boiler manufacturer
should check if the regulator’s mating
with the given boiler type is proper,
and whether it can cause danger.
The regulator is not an intrinsically
safe device, which means that in the
case of malfunction it can be the
source of a spark or high
temperature, which in the presence of
flammable dusts or liquids can cause
fire or explosion. Thus, the regulator
should be separated from flammable
dusts and gases, e.g. by means of an
appropriate body.
The regulator must be installed by a
boiler manufacturer in accordance
with the applicable safety standards.
The programmed parameters should
only be altered by a person
familiarized with this manual.
The device should only be used in
heating systems in accordance with
the applicable regulations.
The electric system in which the
regulator operates must be protected
by means of a fuse, selected
appropriately to the applied loads.
The regulator cannot be used if its
casing is damaged.
In no circumstances can the design of
the regulator be modified.
Electronic isolation of the connected
devices is applied in this regulator.
The regulator consists of two
subassemblies. In the case of
replacing one subassembly, make
sure to maintain compatibility with the
other one. More information on that
issue can be found in the
documentation intended for fitters.
Keep the regulator out of reach of
children.

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 regulator should be in “Stand-by”
mode. It is possible to start up the boiler
(pressing the button and selecting „Turn
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 Setting preset boiler temperature
Preset boiler temperature, just like the
preset mixer circuit temperature, can be set
in the menu:
Boiler settings →Preset boiler temp.
and
Mixer 1-4 settings →Preset mixer temp.
The value set as Preset boiler temp. is
ignored by the regulator if the preset boiler
temperature is controlled by weather sensor.
Regardless of that, the preset boiler
temperature is automatically increased in
order to fill the hot utility water tank and
feed heating mixer cycles.
8.5 FIRE-UP mode
The FIRE-UP mode is used to automatic firing
up of boiler furnace. Total time of firing-up
depends on the regulator settings (feeder
operation time, heater operation time, etc.)
and on the boiler conditions before firing up.
All parameters, which affect firing-up process
are grouped in the menu:
Service settings →Boiler settings →
Firing-up
Detailed description of firing-up cycle:
Fan turns on with the power set in the
parameter of Blowing power- firing up,
Small dose of fuel (approx. 20% basic
dose) is supplied,
Conditions of the furnace are checked –i.e.
once the exhaust temperature has reached
the value of Ex. temp. at the end of firing-
up or has increased by Ex. temp. delta
within the time set in the parameter
Ignition test time elapsed from the fan
start, firing-up process stops. It means
firing-up has been detected and regulator
enters OPERATION mode. In case the
criteria of furnace firing-up have not been
fulfilled, regulator attempts to clean the
furnace and fire it up:
poker is activated to operate over Poker
cycle time,
fuel is supplied over Feeding time,
fan turns on with the power set in the
parameter of Blowing power- firing up,
lighter switches on for Firing-up time. The
regulator checks within this time whether
fuel in the burner has been kindled. Fuel is
deemed kindled once the temperature
increment indicated on exhaust
temperature sensor has reached the value
of Ex. temp. delta or the exhaust
temperature has increased above the value
set in Ex. temp. at the end of firing-up. If
firing-up has been successfully completed,
lighter turns off and regulator enters
OPERATION mode,
Just upon entry the OPERATION mode,
regulator checks whether the exhaust
temperature has increased by the value of
Ex. temp. delta 2. If NOT - regulator
returns to firing-up mode. If YES - it
remains in OPERATION mode.
In case the firing up has not been
successfully completed, further attempts to
fire-up the furnace are carried out with fuel
dose reduced to 10% of the dose used in
first attempt.
Upon execution of three unsuccessful
attempts, the alarm of “Unsuccessful boiler
firing-up attempt”is produced. Boiler
operation is interrupted and cannot be
automatically resumed - operator's
intervention is required. Once the causes of
firing-up failure have been removed, re-start
the boiler.
8.6 STABILIZATION mode
The STABILIZATION mode occurs
immediately after firing up the furnace and is

11
aimed at stabilizing the combustion process
before switching to the OPERATION mode.
The duration of the mode is set in the
parameter Stabilization time.
8.7 OPERATION mode
In OPERATION mode the fan operates
continuously, fuel feeder switches on
periodically. The operation cycle is composed
of feeder operation time and feeder standstill
time.
If a HUW container needs to be filled in
OPERATION mode at pre-set boiler
temperature, which is lower than the value
required to its filling, the regulator will
automatically increase preset boiler
temperature for the time of HUW container
filling
Boiler regulator is equipped with boiler
output modulation function enabling gradual
reduction of boiler output when approaching
the preset boiler temperature.
Levels of boiler output are available in menu:
Boiler settings →Output Modulation
Each of the levels (100%, 50% or 30%) may
be assigned individual values of fuel feeding
time and blow-in output, which determine
actual boiler output. Values of hysteresis (H1
and H2) determine when the boiler should
work with selected output level. Each of
these values is referred to the measured
boiler temperature vs. its preset value. H1
and H2 values may be so set-up that the
modulation will follow without intermediate
level i.e. the boiler output will change
directly from 100% to 30%.
Once the actual boiler temperature has
reached the preset value, the regulator
enters SUPERVISION mode.
8.8 SUPERVISION mode
In the SUPERVISION mode, the regulator
supervises the furnace, so that it would not
go out. For this purpose, the airflow and the
feeder are activated only for a while, rarer
than in the OPERATION mode. Without
causing further temperature increase.
The airflow does not work continuously, it is
activated cyclically together with the fuel
feeder, which prevents the flame from going
out during boiler standstill.
All parameters regarding boiler setup in the
SUPERVISION can be found in the menu:
Service settings →Boiler settings →
Supervision
Parameters of the SUPERVISION mode
should be set in accordance with boiler
manufacturer’s recommendations. They
should be chosen in such a way, that the
furnace did not go out during boiler standstill
(at the same time, it should not fire up too
intensively, as this will trigger increase in the
boiler temperature). Duration of the feeder
operation and interval in the SUPERVISION
mode are set using parameters: Feeding
time, Feeder interval.
Parameters should be selected in
such a way, that boiler
temperature would gradually
decrease when this mode is active.
Improper settings can cause the
boiler to overheat.

12
Airflow in the SUPERVISION mode operates
with power set in the power modulation
parameter 30% Airflow power.
The regulator returns to the OPERATION
mode automatically after boiler temperature
decreases by the value of Boiler hysteresis in
relation to the preset temperature.
Maximum boiler operation time in the
supervision mode is defined by parameter:
Supervision time.If after lapse of this time
from the moment of the regulator’s entering
the supervision mode, there is no need to
reactivate the boiler, the regulator will
commence the process of putting the boiler
out.
8.9 BURNING OFF mode
In BURNING OFF mode, rest of pellets is
burnt and boiler is being prepared to stop or
shut-down.
All parameters, which affect burning-off
process are grouped in the menu:
Service settings →Boiler settings →
Burning off
Detailed description of burning-off cycle:
Fuel feeder stops,
Remaining fuel is burnt –the fan turns on
for the time set in Burning-off time with the
power set in the parameter of Air flush
intensity,
The furnace is cleaned - poker switches on.
Upon automatic burning-off, regulator enters
STOP mode.
8.10 STOP mode
In the STOP mode, the boiler is put out and
awaits signal to resume heating.
A signal to start heating can be:
decrease in preset boiler temperature
below the preset temperature minus the
value of boiler hysteresis (Boiler
hysteresis),
if the boiler is set to work with a buffer -
decrease in upper buffer temperature
below the preset value (Loading start
temperature).
8.11CHIMNEY mode
The regulator has a special CHIMNEY mode.
During the operation of the mode, all
possible heat consumers in the used heating
installation are started simultaneously and
the boiler starts heating up to the preset
power in the parameter Preset power.The
duration of the mode is set in the parameter
Working time.
The CHIMNEY mode is used to test and
regulate boiler operation.
8.12 Domestic how water settings
The device controls temperature of the
domestic how water –HUW container,
provided that a HUW temperature sensor is
connected. If the sensor is disconnected, an
information about lack thereof is displayed in
the main window. The parameter:
HUW settings →HUW pump mode
allows the user to:
disable filling of the tank, parameter Off,
set HUW priority, using the Priority
parameter - in this case, the CH pump is
deactivated to speed up filling of the
HUW container.
set simultaneous operation of the CH and
HUW pump, using parameter No priority.
8.13 Setting preset HUW temperature
Preset HUW temperature is defined by
parameter:
HUW settings →HUW preset temp.
8.14 DHW container hysteresis
Below temperature HUW preset temp.
reduced by HUW hysteresis, the HUW pump
is activated in order to fill the HUW
container.
When value of hysteresis is set too
low, the HUW pump will start faster
after decrease in HUW temperature.
8.15 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:
Summer/Winter → SUMMER mode for
Summer.
The SUMMER function can’t be
activated when the CWU sensor is
disconnected.
It is not allowed to activate
function summer when HUW pump
is disconnected or damaged.

13
Function SUMMER can be activated
automatically, on the basis of readings from
weather sensor. Use following parameters to
activate this function:
Summer/Winter → SUMMER Mode →
Auto
If the automatic detection of summer mode
is switched on, user can set the parameters:
Activ. temperature SUMMER, so outdoor
temp. above which the summer mode will be
switched on and Deactv. temperature
SUMMER, so outdoor temp. below which the
SUMMER mode will be switched off.
8.16 HUW container disinfection
The regulator has a function of automatic,
periodic heating of the HUW container to
temperature of 70°C. The purpose is to
remove bacterial flora from the HUW
container.
The household members must
definitely be informed about the fact
of activating disinfection, as there is
a hazard of scalding with hot utility
water.
Once a week on Sunday night, at 02:00, the
regulator increases the HUW container
temperature. After 10 minutes of keeping the
tank at 70°C, the HUW pump is deactivated
and the boiler resumes normal operation. Do
not enable the disinfection function if HUW
support is deactivated.
8.17 Mixer circuits settings
Settings for the first mixer circuit can be
found in the menu: Mixer 1 settings
Settings for other mixers can be accessed in
next menu items and they are identical for
each circuit.
Settings for mixer without weather sensor
It is necessary to manually set the required
water temperature in the heating mixer
circuit using parameter Preset mixer temp.,
e.g. at a value of 50°C. The value should
allow to obtain the required room
temperature.
After connecting room thermostat, it is
necessary to set a value of decrease in
preset mixer temperature by thermostat
(parameters Mixer room therm.) e.g. at 5°C.
This value should be selected by trial and
error. The room thermostat can be a
traditional thermostat (no/nc), or room panel
ecoSTER TOUCH. Upon activation of the
thermostat, the preset mixer circuit
temperature will be decreased, which, if
proper decrease value is selected, will stop
growth of temperature in the heated room.
Settings for mixer with weather sensor
without room panel
Set parameter Weather contr. mixer to On.
Select weather curve. Using parameter Curve
shift, set preset room temperature following
the formula:
Preset room temperature = 20°C + heating
curve translation.
Example:
To obtain room temperature of 25°C, value
of the heating curve translation must be set
at 5°C. To obtain room temperature of 18°C,
value of the heating curve translation must
be set at -2°C.
In this setup, it is possible to connect a room
thermostat which will equalize the inaccuracy
of selecting heating curve, if the selected
heating curve value is too high. In such case,
it is necessary to set the value of preset
mixer temperature decrease by thermostat,
e.g. at 2°C. After opening of the thermostat
contacts, the preset mixer circuit
temperature will be decreased, which, if
proper decrease value is selected, will stop
growth of temperature in the heated room.
Settings for mixer with weather sensor and
with room panel
Set parameter Weather contr. mixer to On.
Select weather curve. The ecoSTER TOUCH
panel automatically translates the heating
curve, depending on the preset room
temperature. The regulator relates the
setting to 20°C, e.g. for preset room
temperature = 22°C, the regulator will
translate the heating curve by 2°C, for
preset room temperature = 18°C, the
regulator will translate the heating curve by
-2 °C. In some cases it may be necessary to
fine-tune the heating curve translation.
In this setup the ecoSTER TOUCH room panel
can:
- decrease the heating cycle temperature by
a constant value when the preset room
temperature is reached. Analogously, as

14
specified in the previous point (not
recommended), or
- automatically, continuously correct the
heating cycle temperature.
It is not recommended to use both options at
the same time.
Automatic correction of room temperature is
carried out in accordance with the following
formula:
Correction = (Preset room temperature -
measured room temperature) x room
temperature coefficient /10
Example:
Preset temperature in the heated room (set
at ecoSTER TOUCH) = 22°C. Temperature
measured in the room (by ecoSTER TOUCH)
= 20°C. Room temp. factor = 15.
Preset mixer temperature will be increased
by (22 °C - 20 °C) x 15/10 = 3 °C.
It is necessary to find appropriate value of
the Room temp. factor. The higher the
coefficient, the greater the correction of
preset boiler temperature. If the setting is
“0”, the preset mixer temperature is not
corrected.
Note: setting a value of the room
temperature coefficient too high may cause
cyclical fluctuations of the room temperature!
8.18 Weather controlled operation
Depending on the temperature measured
outside the building, both preset boiler
temperature and temperatures of mixer
circuits can be controlled automatically. If
proper heating curve is selected, the
temperature of the circuits is calculated
automatically, depending on the outdoor
temperature. Thus, if the selected heating
curve is appropriate for the given building,
the room temperature stays more or less the
same, regardless of the temperature outside.
Note: During trial and error selection of
appropriate heating curve, it is necessary to
exclude influence of the room thermostat on
regulator operation (regardless of whether
the room thermostat is connected or not), by
setting the parameter:
Mixer 1 settings →Mixer room therm. to
“0”.
If a room panel ecoSTER200/ecoSTER
TOUCH is connected, it is also necessary to
set the parameter Room temp. factor to “0”.
Guidelines for proper setting of the heating
curve:
floor heating 0,2 -0,6
radiator heating 1,0 - 1,6
boiler 1,8 - 4
Guidelines for selection of appropriate
heating curve:
- if the outdoor temperature drops, and the
room temperature increases, the selected
heating curve value is too high,
- if the outdoor temperature drops, and the
room temperature drops as well, the selected
heating curve value is too low,
- if during frosty weather the room
temperature is proper, but when it gets
warmer - it is too low, it is recommended to
increase the Curve shift and to select a lower
heating curve,
- if during frosty weather the room
temperature is too low, and when it gets
warmer - it is too high, it is recommended to
decrease the Curve shift and to select a
higher heating curve.
Buildings with poor thermal insulation require
higher heating curves, whereas for buildings
which have good thermal insulation, the
heating curve can have lower value.
The regulator can increase or decrease the
preset temperature, calculated in accordance
with the heating curve, if it exceeds the
temperature range for the given circuit.
8.19 Night decrease settings description
Night time decrease for heating circuits,
HUW container and circulation 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

15
reduced automatically, without loss of
heating comfort by reducing fuel
consumption.
Decrease of preset temperature in selected
time intervals is indicated by the symbol “S”
on the main screen.
To activate time intervals, set the parameter
Night time decrease for the given heating
circuit to ON. The parameter Decrease set
the temperature reduction, one for all time
intervals.
Night time decreases can be defined
separately for every day of the week set
Schedule.
Select temperature reduction and beginning
and end of respective time interval. The time
intervals for 24 hours are fixed at 30min.
Time periods.
Night time decrease for boiler
In the setting time intervals the boiler works.
Outside of these time intervals, the boiler is
turned off.
8.20 Circulating pump control
The settings for the circulating pump can be
found in the menu:
Night time decrease
and
Service settings → CH and HUW settings
Setting of circulating pump control is
analogical to night decrease setting.
Circulating pump switches on in selected
time intervals. In disregarded time intervals
circulating pump will start and remain in
operation for the period of time set in
Circulating pump operation time , then will
stop and remain out of operation for the
period of time set in Circulating pump
standstill time.
8.21 Fuel level setup
Activating the fuel level gauge
In order to enable display of the fuel level,
set value of parameter
Menu → Boiler settings → Fuel level →
Alarm level
to a value greater than zero, e.g. 10%.
Tip: fuel level can also be seen in room panel
ecoSTER200 and ecoSTER TOUCH.
Operation of fuel level indicator
Any time upon filling fuel tank, press and
hold pressed current fuel level value.
Following prompt appears:
Set fuel level at 100% Once selected and
confirmed YES, fuel level is set at 100%.
Once selected and confirmed YES, fuel level
is set to 100%.
Note: Fuel may be replenished at any time
without a need to wait for complete empty
fuel tank. Replenish fuel always to the level
corresponding to 100% level of the fuel tank
and set 100% level as described above.
Description of operation
The regulator calculates the fuel level basing
on the current fuel consumption. Default
settings do not always correspond to the
actual consumption of fuel by the given
boiler, therefore, for proper operation this
method requires the regulator user to
perform level calibration. No additional fuel
level sensors are required.
Calibration
To perform calibration - fill the fuel tank to
the level corresponding to its full load and
set the parameter:
Boiler settings →Fuel Level → Fuel level
calibration →Fuel Level 100%
The indicator in the main window will be set
to 100%. On-going calibration process is
signalled by flashing fuel level gauge. The
gauge will flash until the time of marking the

16
point corresponding to minimal fuel level.
One must systematically control the
decreasing level of fuel in the bin. When the
level reaches the requested minimum, set
the value of the parameter:
Boiler settings →Fuel level → Fuel level
calibration →Fuel Level 0%
8.1 Information
Information" menu allows to preview
temperatures being measured and to
recognize which equipment is currently ON.
Upon connection of mixers'
extension module, information
windows of additional mixers are
displayed.
8.2 Operation with additional feeder
The regulator is adapted to work with fuel
charging sensor, which is part of boiler
fittings.
On the basis of the settings made in the
schedule of additional feeder operation in
the menu:
Schedule of extra feeder
and signals received from the fuel level
sensor, the regulator controls replenishment
of fuel in boiler bin.
Upon activation set by time interval of the
schedule, second feeder starts to operate
according the algorithm defined by the
parameter Feeder operat time 2. During
operation of additional feeder, signal of bin
charging sensor is used.
8.3 Support for poker automation
The regulator supports poker automation,
which allows to improve the conditions of
burning of inferior quality fuel and cleaning
the furnace from ashes.
Cleaning of the hearth is performed by a
poker in the FIRE-UP and BURNING OFF
mode.
In the case when the boiler stays for a long
time in the OPERATION or SUPERVISION
mode it is possible to automatically start
cleaning the boiler, the parameter Burner
cleaning is used for this purpose.
8.4 Information
"Information" menu allows to preview
temperatures being measured and to
recognize which equipment is currently ON.
Upon connection of mixers'
extension module, information
windows of additional 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.
8.5 Manual control
Regulator offers possibility to manual start of
working equipment such as pump, feeder
motor or fan.
This feature enables checking whether the
given equipment is fault-free and properly
connected. Access to manual control menu is
possible only in STOP mode, i.e. when the
boiler is OFF.
OFF –equipment is switched OFF, ON –
equipment is switched ON.
Long-term operation of the fan, the
feeder or other working equipment
may lead to occurrence of
hazardous conditions.
8.6 Working according to schedule
In the regulator is possible to switch off the
boiler at defined intervals. In the absence of
demand for heat, e.g. in summer, one can
disable the operation of the boiler at a
certain time and thus reduce fuel
consumption.
Time intervals are entered in the menu:
Work acc. schedule
Note: the menu item may not be available if
the boiler manufacturer does not provide
such a function in the boiler.

Short operation description: The boiler pump (6) starts operation after the boiler has exceeded the CH pump
activation temperature. When the temperature from the sensor (17) reaches the Loading end temperature,
the regulator switches off the burner and goes into the STOP mode. When the temperature from the sensor
(16) drops below the Loading start temperature then the regulator ignites the burner and switches to the
OPERATION mode. When the water entering the boiler is cold, then the thermostatic valve (15) closes. This
causes the boiler water to flow in a short cycle: boiler (1) - throttle valve (15) - thermostatic valve (6) -
pump (6). The thermostatic valve (15) opens after the return temperature to the boiler increases, directing
the boiler water to the heat buffer.

Short operation description: CH pump (6) and and HUW pump (12) start once the boiler temperature has
exceeded CH activation temp. (usually: 40C). In case the water, which flows to the boiler is cold,
thermostatic valve (7) closes. It causes the flow of boiler water in short circuit: boiler (1) –throttle valve (8)
- thermostatic valve (7) –pump (6). Thermostatic valve (7) opens upon increase of boiler return
temperature and directs boiler water to CH system. Once the temperature measured by the sensor (13) has
dropped to below HUW preset temp., HUW pump (12) starts operation. HUW pump (12) stops upon
completed filling of HUW container (11), i.e. when the temperature measured by the sensor (13) is equal to
HUW preset temp..
