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.
Keep the regulator out of reach
of children.

2General
The regulator is an advanced electronic
device intended for controlling boilers with
automated solid fuel feeders and ignitors.
Flame is detected via the exhaust
temperature sensor.
It can be used to control the operation of an
unregulated central heating circuit, HUW
circuit and three regulated heating circuits.
Preset temperature of heating circuits may
be set on the basis of weather sensor read-
out. A possibility to work together with room
thermostats helps to maintain comfortable
temperature in heated rooms. Moreover, if
needed, the equipment switches on gas -or
oil fired reserve boiler.
The regulator may operate in connection with
additional control panel installed in rooms.
Regulator is easy to operate in an intuitive
manner. It may be used in households and
other similar premises and in light industry
facilities.
3Information about documentation
The regulator manual is a supplement for the
boiler manual. In particular, except for this
manual, the boiler manual should also be
observed. The regulator manual is divided
into two parts: for user and fitter. Yet, both
parts contain important information,
significant for safety issues, hence the user
should read both parts of the manual.
We are not responsible for any damages
caused by failure to observe these
instructions.
4Storage of documentation
This assembly and operation manual, as well
as any other applicable documentation,
should be stored diligently, so that it was
available at any time. In the case of removal
or sale of the device, the attached
documentation should be handed over to the
new user / owner.
5Applied symbols
In this manual the following graphic symbols
are used:
- useful information and tips,
- important information, failure to
observe these can cause damage of
property, threat for human and
household animal health and life.
Caution: the symbols indicate important
information, in order to make the manual more
lucid. Yet, this does not exempt the user from the
obligation to comply with requirements which are
not marked with a graphic symbol.

The message: ACTIVE REGULATOR? appears.
Confirm the message. Boiler enters firing-up
stage. There is also another method of boiler
start-up. Press MENU button and find and
press button in pie menu.
To stop the boiler - press MENU button, and
find and press button in pie menu.
Note: regulator enters burning off phase.
Upon completion of burning off stage, the
message BURNER OFF appears.
8.3 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.
Mixer 1,2,3,4 settings →Preset mixer
temp.
Regardless of that, the preset boiler
temperature is automatically increased in
order to fill the hot utility water tank and
feed heating mixer cycles.
8.4 FIRING-UP
The FIRING-UP mode is used for automatic
firing-up of furnace in the boiler. All
parameters which influence the firing-up
process can be found in menu:
Service settings →Burner settings →
Firing-up
If the firing-up failed, additional attepnts will
be made. Consecutive attempts are
visualised by numbers next to the lighter
symbol .
After three unsuccessful attempts, an alarm
Failed firing-up attempt is reported. In such
case, the boiler operation is halted. Boiler
operation cannot be continued automatically
- service crew must intervene. After
removing causes of impossibility to fire-up,
the boiler must be restarted.
8.5 OPERATION
The fan operates continuously. Fuel feeder is
activated cyclically. A cycle consists of feeder
operation time and duration of feeding
interval
Parameters related with the Operation mode
are: Feeder operation time and Fan output
in:
Boiler settings →Output modulation
8.6 Regulation mode
There are two regulation modes for
stabilizing the set temperature of the boiler:
Standard and FuzzyLogic
Boiler settings →Regulation mode
Operating in Standard Mode
When the boiler temperature reaches its set
value, the regulator switches to
SUPERVISION mode.
The regulator has a boiler output modulation
mechanism allowing it to gradually reduce
the output as the boiler temperature nears
its set value
Three boiler output levels can be set:
maximum, medium, and minimum. Each
level can be additionally adjusted with
individual fuel feeding times and fan speeds,
affecting the actual output of the boiler. The
output level parameters are accessible
through the menu
Boiler Settings →Output modulation.
The regulator sets the current output of the
burner depending on the set temperature of
the boiler and H1 and H2 hysteresis settings
It is possible to set the H1 and H2 values to
modulate the output withouth the medium
power stage, ie. reducing output from 100%
to 30%, skipping the 50% output (right side
of the figure below)

11
Operating in FuzzyLogic mode
In FuzzyLogic mode, the regulator
automatically sets the output of the burner in
order to maintain the set boiler temperature.
The regulator uses the output settings
predefined in Standard mode. This mode
does not require setting the H1 and H2
hysteresis.
Note: If only the HUW is heated
(summer mode), it is recommended
to set the regulator to Standard
mode.
After the set temperature is exceeded by 5
degrees, the boiler switches to SUPERVISION
mode.
8.7 SUPERVISION
In SUPERVISION mode, the fan and the
feeder are switched on cyclicall at larger
intervals than in OPERATION mode. This is to
prevent the fire from being extinguished.
Supervision parameters can be found in
menu:
Service Settings →Burner Settings →
Supervision
SUPERVISION parameters should be set in
accordance with the recommendations of the
boiler or burner manufacturer. The
parameters should be adjusted to prevent
the furnace from extinguishing during
intervals.
Parameters should be so selected
that the boiler temperature in this
mode gradually drops. Incorrect
settings may lead to boiler
overheating.
When the supervision time expires, the
regulator switches to EXTINGUISHING mode,
unless the boiler temperature decreases and
the boiler automatically switches to
OPERATION mode.
For the setting Supervision time =
0, the regulator skips the
SUPERVISION mode and enters the
BURNING-OFF mode.
When the Supervision time = 255,
the regulator will work continuously
in SUPERVISION mode, until the
boiler temperature decreases and it
automatically switches to
OPERATION mode.
8.8 BURNING OFF
The extinguishing process does not occur
when coal is the fuel of choice. When pellets
are the fuel, they are burned off for several
minutes (depending on the set time). After
BURNING OFF, the regulator switches to
STANDSTILL.
8.9 STANDSTILL
In the STANDSTILL 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.
8.10 Domestic hot water settings HUW
The device controls temperature of the
domestic how water - HUW –tank, 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:
Menu →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 tank.
set simultaneous operation of the CH and
HUW pump, using parameter no priority,
The regulator has a function of automatic,
periodic heating of HUW container to 70 °C
to eliminate bacterial flora from the HUW
container.
Keep the tenants informed of
activating the disinfection function
as there is risk of being burnt with
hot usable water.
The regulator increases the HUW container
temperature once a week, at 2:00 a.m.
Monday. After 10 minutes of maintaining the
temperature at 70 °C, the HUW pump is
switched off and the boiler returns to normal
operation. Do not activate the disinfection
function when the HUW support is off.
8.11 Setting HUW preset temperature
Preset HUW temperature is defined by
parameter:
HUW settings →HUW preset temp.
HUW tank hysteresis
When the temperature drops below the HUW
set temperature –HUW tank hysteresis, the
HUW pump will start in order to supply the
HUW tank.
In low hysteresis values, the HUW
pump will start faster when the
HUW temperature drops.
8.12 HUW Circulation
The settings are located in:
HUW Settings→Circulation pump night
time decrease
and
Service Settings→ CH and HUW settings
The time settings of the circulation pump are
analogous to the settings of night time
decrease. The pump will be off in the defined
time periods. At other times, the pump will
be on at Circulation pump working time
between every Circulation pump stand-by
time.
8.13 Enabling the Summer function
To enable the SUMMER function, heating the
WUH tank without the need of supplying the
CH installation, set the Summer mode
parameter to on.
Menu Summer mode
In Summer mode, all heat
receivers may be shut off, so
before enabling it please make
sure that the boler does not
overheat.
If the weather sensor is connected, switching
between SUMMER and WINTER mode may
occur automatically.
8.14 Mixer circuits settings
Settings for the first mixer circuit can be
found in the menu:
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

13
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 thermostat ecoSTER TOUCH)
Set parameter Weather contr.mixer to on.
Select weather curve as per point 8.15
Using parameter Curve translation, set
preset room temperature following the
formula:
Preset room temperature = 20°C + heating
curve translation.
Example.
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 thermostat ecoSTER
TOUCH
Set parameter Weather contr.mixer to on.
Select weather curve as per point. 8.15
The ecoSTER TOUCH regulator 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 described in point. 8.15
it may be necessary to fine-tune the heating
curve translation.
In this setup, the ecoSTER TOUCH room
thermostat can:
- decrease the heating cycle temperature by
a constant value when the preset room
temperature is reached. Analogously, as
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 ecoSTER200) = 22 °C. Temperature
measured in the room (by ecoSTER200) =
20 °C. Room temp. coeff. = 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. coeff. Range: 0…50. 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!
8.15 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:

14
Mixer 1 settings →Mixer room therm.=
0.
If an ecoSTER TOUCH room panel is
connected, also temporarily set the Room
temperaturę factor = 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 translation 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 translation 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.
8.16 Description of night time decrease
settings
Boiler night time decreases
The boiler operates in selected time
intervals. Outside of the selected intervals,
the boiler is burned off.
Night time decreases for heating
circuits, HUW container and circulation
pump operation.
The intervals can be used to define time
periods at which lower preset temperature
may be set e.g. for a night time or when the
user is not at home (e.g. he/she left for a
work/school). This feature enables automatic
reduction of preset temperature without
compromising the heat comfort and reduces
fuel consumption.
To activate time intervals, set the
parameter: Night time decrease for the given
heating circuit to ON.
Night time decrease may be set for working
days, Saturdays and Sundays.
The example of night time decrease of preset
temperature from 22:00 to 06:00 next day
and from 09:00 to 15:00 is given below.
Note! Setting of time intervals for
24 hours (one day) should start
from 00:00!

15
In the given example, the regulator will set
the decrease of preset temperature by 3 °C
from 00:00 to 06:00, and will keep the
preset value (without the decrease) from
06:00 to 09:00. Then, it will set the decrease
by 5 °C from 09:00 to 15:00, and will keep
the preset value (without the decrease)
again from 15:00 to 22:00; and again will
set the decrease by 3 °C from 22:00 to
23:59.
Time interval is disregarded when
its decrease is set to "0" even
though "from... to ..." values have
been entered.
Decrease of preset boiler
temperature in selected time
intervals is indicated by the symbol:
on the main screen
8.17 Fuel level setup
Activating the fuel level gauge
In order to enable display of the fuel level,
set value of parameter
Boiler settings →Fuel level →Alarm level
to a value greater than zero, e.g. 10%. By
pressing the right or left box in the main
window you can select the fuel level
indicator. Fuel level can also be displayed on
the ecoSTER TOUCH room panel.
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
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

9Description of alarms
9.1 Boiler max. temp. exceeded
Overheating protection occurs in two stages.
First, after the boiler cooling temperature is
exceeded, the regulator tries to decrease the
temperature by transferring the heat excess
to the HUW tank and by opening the mixer
actuators (only when mixer use = CH
enabled). If the temperature measured by
the WUH senor exceeds the Max. WUH
temp., the WUH pump will be switched off in
order to prevent burns. When the
temperature on the boiler drops, the
regulator returns to normal operation. If the
temperature continues to rise (reaching
95C), a constant boiler heating alarm will
start, paired with a sound signal.
The alarm can be cleared by pressing the
Touch and Play button or turning the power
supply off and on.
Note: placing the temperature
sensor outside the water coating of
the boiler, for example on the
outlet pipe, is unfavourable
because it can delay the detection
of overheating.
9.2 Feeder max. temp. exceeded

17
This alarm will occur after the feeder
temperature exceeds the service parameter:
Service setting s→Burner settings →
Max. feeder temp.
In such cases, the regulator will attempt to
push out the burning fuel from the feeder by
switching it on for a short time. If three
consecutive attempts to switch the feeder on
do not reduce the temperature, the feeder
will be switched on for a a longer time and
report a constant alarm. Before returning to
regular operation, remove the excess fuel
from the combustion chamber. For additional
information, see pt. 15.
The flame return protection
function will not work if there is no
power supply to the regulator.
The regulator cannot be used as
the only flame return protection.
Use additional automatic
protection.
9.3 Feeder control system failure
The regulator has an additional protection
preventing it from feeding fuel constantly.
This informs the user about failures in the
electrical system controlling the fuel feeder.
In case of alarm, stop the boiler and
repair the regulator as soon as possible.
It is also possible to continue operation in
emergency mode. Before continuing
operation, mane sure that the combustion
chamber does not contain excessive unburnt
fuel. If so, remove the excess fuel. Ignition
with excessive fuel may lead to explosion of
combustion gasses! Emergency mode is
activated after entering the special
password: 4445. Before activating
emergency mode, familiarize yourself with
the user manual. After accepting the
password, the feeder control is taken over by
the emergency system and the boiler
continues to operate.
Note: operating in emergency
mode is allowed only under user
supervision and until the arrival of
the service team to remove the
failure. If user supervision is not
possible, extinguish the boiler.
When operating in emergency
mode, prevent the consequences of
improper feeder work (feeder
working constantly or not at all).
9.4 Boiler temp. sensor failure
This alarm occurs when the boiler
temperature sensor is damaged or when its
measurement range is exceeded. Check the
sensor and replace it if necessary.
See temperature senor check in pt.
13.10.
9.5 Feeder temp. sensor failure
This alarm occurs when the sensor is
damaged or when its measurement range is
exceeded.
See temperature senor check in pt.
13.10.
9.6 Exhaust temperature sensor failure
This alarm occurs when the sensor is
damaged or when its measurement range is
exceeded.
See temperature senor check in pt.
13.10.
9.7 Boiler ignition failed
This alarm occurs after the third failed
attempt to automatically ignite the furnace
The causes of this alarm include: faulty
igniter or fan, damaged fuel feeding system,
improper parameter settings, low fuel
quality, lack of fuel in the container.
Note: Before continuing operation,
make sure that the combustion
chamber does not contain
excessive unburnt fuel. If so,
remove the excess fuel. Ignition
with excessive fuel may lead to
explosion of combustion gasses!
9.8 Exhaust temperature not met.
Check fuel quality
This alarm is sounded when the exhaust
gases are not heated above the lack of fuel
detection threshold in the exhaust
temperature increase time. The alarm
prevents filling the combustion chamber with

18
unburnt fuel. Check the quality and moisture
of the fuel.
9.9 Boiler overheating, STB limiter
open
This alarm occurs when the independent
safety thermostat protecting the boiler from
being overheated is activated. The burner is
switched off. After the boiler’s temperature
drops, unscrew the round cover of the
temperature limiter and press the reset
button.
9.10 Max exhaust temperature
exceeded. Sensor damage danger!
This alarm occurs only when using the
GRATE and exceeding the maximum exhaust
temperature. The fan is turned off. Its aim is
to protect the exhaust temperature sensor
from being damaged by temperatures
exceeding its resistance level. When the
temperature on the boiler drops, the
regulator returns to normal operation.
9.11 Lack of communication
The control panel is being linked with the
rest of the electronics with RS485 digital
communication link. In case a cable of this
link will be damaged, an alarm will occur on
the screen with the information “Attention!
No communication”.
The controller doesn’t stop to operate and
works normally with before preset
parameters. It is required to check the
connection cable between control panel and
the module and replaced it with a new one or
repair it.
9.12 Unsuccessful attempt of buffer
loading
This feature has an application only after
module B connection. It is a silent alarm,
which informs about unsuccessful attempt of
adding fuel from additional fuel container
(bunker) to boiler container. In case, when
during preset time of container loading, a
sensor in this container will not detect the
increase of fuel level, this alarm will occur.
This signalisation does not shut down boiler
automatic operation.
9.13 Fan or fan speed sensor failure
This alarm occurs then the fan’s speed
sensor or the fan itself is damaged, based on
the voltage capacity on the terminal
controlling the sensor. The regulator switches
off the fan.

In order for the valve (6) to be able to effectively increase the return water temperature,
set a high set temperature of the boiler. In order to improve the water circulation in
natural systems (highlighted circuit in the figure): use large nominal diameter pipes and
four-way valve, avoid unnecessary angles and reductions, maintain a min. 2° horizontal
pipe slope, etc.
If the sensor (3) is attached to the pipe, isolate it with foam surrounding the pipe and
sensor.
