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 a modern electronic device
designed to control pellet-fired boiler
operation with optical flame brightness
sensor. The regulator is compatible with an
air pressure sensor allowing for a precise
combustion control.
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.
6Directive WEEE 2002/96/EG Act on
electrical and electronic equipment
Recycle the product and the
packaging at the end of the
operational use period in an
appropriate manner.
Do not dispose of the product
together with normal waste.
Do not burn the product.

on the main screen and select "reserve
boiler". The pellet boiler is then burned
off. The reserve boiler is switched on
after the pellet boiler is burned off.
Details on the reserve boiler are given in
sec. 12.15.

12
8.4 Setting preset boiler
temperature
Preset boiler temperature, just like the
preset mixer circuit temperature, can be set
in the menu (possible settings of these
temperatures are limited by the scope of
their corresponding regulator service
parameters).
Menu→Boiler settings > Preset boiler
temp.
Menu→Mixer 1,2,3,4 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 FIRING-UP
The FIRING-UP mode is used for automatic
firing-up of furnace in the boiler. Total
duration of the firing-up process depends on
regulator settings (feeder operation time,
heater operation time, etc.) and on the
boiler’s status before firing-up. All
parameters which influence the firing-up
process can be found in menu:
Menu →Service settings >
Boiler settings > Firing-up
If firing up the furnace fails, further attempts
are carried out during which the fuel dose
(feeding time) is reduced to 10% of the dose
in the first attempt.
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.
8.6 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:
Menu →Boiler settings →Output
modulation.
8.7 SUPERVISION
The regulator automatically enters the
SUPERVISION mode without any user's
intervention once actual temperature has
exceeded the boiler preset temperature by
5°C.
In the SUPERVISION mode, the regulator
supervises the fire in the furnace so that it
does not burn off. To achieve that, the
burner power is kept low which together with
correctly adjusted parameters prevents any
increase of the temperature. Burner power in
the SUPERVISION mode and other
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. They should
be such values so that the fire in the furnace
does not burn off during boiler standstills
(and it should not burn too intensely as the
boiler temperature may increase). Feeder
operation and standstill times in the
SUPERVISION mode are set with the
following parameters: Feeding Time
SUPERVISION, Cycle time SUPERVISION and
Blow-in SUPERVISION mode.
Parameters should be so selected
that the boiler temperature in this
mode gradually drops. Incorrect
settings may lead to boiler
overheating.
The maximum boiler operation time in the
SUPERVISION mode is defined by
Supervision time.If, after this time, the

13
boiler does not have to operate again after it
entered the SUPERVISION mode, the
regulator initiates boiler burn-off.
For the setting Supervision time = 0,
the regulator skips the SUPERVISION
mode and enters the BURNING-OFF
mode.
8.8 BURNING OFF
In the PUTTING OUT mode, remains of the
pellet are burnt out and the boiler is
prepared for standstill or deactivation.
All parameters which influence the process of
putting out can be found in menu:
Service settings >
Boiler settings > Burning off
The regulator stops fuel feeding and
performs periodical air flushes to burn fuel
residues. When the flame brightness
decreases or the maximum burning-off time
elapses, the regulator enters the
STANDSTILL mode.
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 how water settings
DHW
The device controls temperature of the
domestic how water - DHW –tank, provided
that a DHW temperature sensor is
connected. If the sensor is disconnected, an
information about lack thereof is displayed in
the main window. The parameter:
Menu →DHW settings > DHW pump
mode allows the user to:
disable filling of the tank, parameter
off,
set DHW priority, using the priority
parameter - in this case, the CH pump
is deactivated to speed up filling of
the DHW tank.
set simultaneous operation of the CH
and DHW 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 preset DHW
temperature
Preset DHW temperature is defined by
parameter:
DHW settings > Preset DHW temp.
8.12 DHW tank hysteresis
Below temperature DHW preset temp.
reduced by DHW tank hysteresis, the DHW
pump is activated in order to fill the DHW
tank.
When value of hysteresis is set too
low, the DHW pump will start faster
after decrease in DHW temperature.
8.13 Enabling the SUMMER function
In order to activate the SUMMER function,
which enables to load the DHW tank in the
summer, without the need for activating the
CH system and mixer cycles, set the
parameter DHW pump operation mode to
summer.
Do not enable the summer function
if the DHW pump is disconnected
or damaged.

14
The SUMMER function can be enabled
automatically, on the basis of readouts from
the weather sensor. This functionality is
enabled with the following parameters:
DHW settings > Auto SUMMER detect.
DHW settings > Activ.temp.SUMMER
DHW settings > Deactiv.temp.SUMMER
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
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

15
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:
Mixer 1 settings > Mixer room therm. to
“0”.
If a room panel ecoSTER200 is connected, it
is also necessary to set the parameter Room
temp. coeff. 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
Drawing 1 Heating curves.
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.
Fig. 5 Boiler night time decreases
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!
Fig. 6 Night time decreases for heating circuits
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 Circulating pump control
Note: the circulating pump functionality is
available only if an additional extension
mixer module.
The settings can be found in:
MENU →DHW Settings → Circulation
pumps night-time decrease
and
Menu →Service settings → CH/DHW
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

17
period of time set in Circulating pump
standstill time.
8.18 Fuel level setup
Activating the fuel level gauge
In order to enable display of the fuel level,
set value of parameter

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:
Menu →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
the value of the parameter:
Menu →BOILER SETTINGS →Fuel Level
→ Fuel level calibration →Fuel Level 0%
Calibration can be skipped if the Feeder
Efficiency and Tank capacity,parameters are
set correctly in: Menu →Service settings
→Burner settings → Operation.
8.19 Operation with additional
feeder
After the additional module B is connected,
the regulator may be used with low tank fuel
level sensor (fuel feed from bunker). After
the sensor is activated (contacts open), the
regulator activates the additional tank for the
Additional feeder - operation time to refill the
main fuel tank. This parameter can be found
in: Menu →Service settings →Burner

sensor (not necessary for the operation of the system).
To improve water circulation in gravitational circuit of the boiler (the circuit is indicated on
the diagram with a bold line) it is necessary to: (i) use pipes and 4-way valve of large DN
value, (ii) avoid using excessive number of elbows and cross section reductions, and (iii)
apply other rules of gravitational circuit construction - e.g. keeping of gradients, etc.
In case the return temperature sensor is of contact type -provide the sensor with heat
insulation to isolate it from the environment and improve its thermal contact with a pipe
by application of thermal paste. Set the preset boiler temperature at so high a value that
heat output required for the mixer circuit and to heat-up return water to the boiler is
guaranteed.
