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,
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 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 is equipped with internal
overcurrent protection, one-polar,
which have an impact on the safety of
use. The condition of its correct
operation is the proper connection of
the power cable to the electrical
network. It is absolutely necessary to
ensure that the L phase wire is not
changed with the N neutral wire.
Ensure that the polarity of the L and N
wires is correct by measuring at their
terminals.
Prevent access to the regulator of
people who do not know the content of
this manual, especially children.

2General information
The regulator ecoMAX920P1-K TOUCH is a
device designed to control the operation of a
boiler with automatic feeding of solid fuel
with a igniter. Flame detection is performed
with the use of an optical flame brightness
sensor. 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). The
regulator may operate in connection with
additional wire room thermostat/panel
ecoSTER200, ecoSTER TOUCH and wireless
room thermostat/panel eSTER_x80 or
eSTER_x40 installed in rooms and
ecoNET300 Internet module. Additionally it
cooperates with ecoLAMBDA module and
extension B and C modules.
The regulator may be used in households
and other similar premises and in light
industry facilities.

Make sure fuel is present in the tank and
tank hatch is closed. Now boiler may be
switched on. To start the boiler, press “Boiler
Off” at any place on the screen. The message
“Active regulator?”appears.
After accepting the boiler goes into Firing-up
phase. There is a second method of
integration of the boiler. Press the menu
button, then press in the menu button .
To turn off the boiler, press the menu button,
then press in the menu button , then
the controller will go to the process of
burning off. Only after burning off completion
will be information "Boiler Off".
8.3 Preset temperature setting
The boiler preset temperature and HUW
preset temperature, and mixer circuits preset
temperature can be set in the menu
(possible temperatures are restricted with
range of respective service parameters):
Boiler settings →Preset boiler
temperature
HUW settings →Preset HUW
temperature
Mixer settings 1-5 →Preset mixer
temperature
The parameter value Preset boiler
temperature, is by regulator bypassed when
the preset boiler temperature is controlled by
weather sensor. Regardless of that, the
preset boiler temp. is automatically increased
to load the hot user water tank and power
heating circuits of mixers.
8.4 FIRE UP mode
The FIRE UP mode is for automatic firing up
of furnace in boiler. Total time of firing up
process is dependand on controller’s settings
and on boiler’s condition before firing up.
Parameters influencing firing up process are
in the menu:
Service settings →
Burner settings →Fire up
In case of failed attempt of firing up the
furnace, another attempts are taken during
which amount of fuel is reduced to 10% of
first attempt’s dose. Further attempts of
firing up are signaled by numbers next to the
igniter . After three failed firing up
attempts an alarm “Unsuccessful boiler
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.
8.5 OPERATION mode
In the OPERATION mode the burner fan
operates constantly. Fuel feeder is engaged
periodically. Period consists of feeder
operating time and pause in fuel feeding
time.
The Feeding cycle time parameter is located
in the menu:
Service settings →Burner settings →
Operation
Feeder operation time is calculated
automatically depending on the required
current power of the burner, Feed efficiency
and Calorific value of the fuel. Parameters of
blow-in and exhaust output for different
power levels of the burner are available in
the menu:

8.6 Regulation modes
Can choose between two adjustment modes
responsible for stabilizing the boiler preset
temperature Standard and Fuzzy Logic. This
mode changes in the menu:
Boiler settings →Regulation mode
Standard mode operation
If the boiler’s temperature reach preset one
then the controller switches off to
SUPERVISION mode.
The regulator is equipped with boiler’s power
modulation mechanism which allows for
gradual power reduction when approaching
the preset temperature. There are three
boiler power levels: Maximum, Intermediate,
Minimum. 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:
Boiler settings →Output modulation
The controller regulates burner’s power with
which it operates depending on preset
temperature and defined hysteresis The
Intermediate power-hysteresis H2 and
Minimum power-hysteresis H1.
It is possible to configure hysteresis volumes
H1 and H2 in such a way that modulation is
done without intermediate position. That
means switching from Max. to Min. with
omission of Intermediate power.
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
H2 and H1 hysteresis 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 H2 and H1. It also
allows for quicker reach the preset
temperature. In addition, you can adjust the
boiler output in FL mode by the parameters
Min. boiler output FL and Max. boiler output
FL.
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 temperature by
5ºC the controller switches into
SUPERVISION mode.
8.7 SUPERVISION mode
The SUPERVISION mode is applicable either
in regulation in Standard and Fuzzy Logic
mode. The regulator switches into
SUPERVISION mode automatically without
user’s intervention:
in Standard regulation mode –after
reaching the boiler preset temperature,
in Fuzzy Logic regulation mode –after
exceeding boiler preset temperature by
5ºC.
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 the
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

12
mode is set using following parameters:
Boiler output in Supervision mode,Cycle
time and Fan output.
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 service
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 mode
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 the 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 STOP mode.
8.9 STOP mode
In the STOP 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),
by boiler operation configuration with the
buffer decrease of top buffer temperature
below preset value (Buffer loading start
temperature).
8.10 GRATE mode
Some boilers have an additional grate to
burn other fuels such as wood waste, etc. To
activate the grate, move the parameters
available in the menu:
Boiler settings →Boiler oper. mode
from "pellet" to "grate". In the grate mode
fuel feeder is turned off. The combustion
process is regulated by the blow-in fan and
exhaust fan. Fans power, when working with
grate, is set in the menu:
Boiler settings →Burner settings →
Grate →Fan output - Grate mode
and
Extraction output - Grate mode
The values of parameters such as: Preset
boiler temperature, Boiler hysteresis and
Fuel detection time are individually adjusted
for the grate mode. This allows you to define
different properties of boiler operation for
operation modes "grate" and "pellets". When
using the grate an alarm "No fuel" can
appear. This alarm occurs when a
temperature drops below the value of the
parameter:
Service settings →CH and HUW settings
→CH pump activation temperature and
then for a period of 10 minutes there has
been no growth.
8.11 Burner cleaning
The regulator is used for cleaning the furnace
of ashes generated in the combustion
process. For this purpose, the regulator uses
the work of the blow-in and exhaust fan with
power set in the Cleaning intensity
parameter. In the parameter Burner
cleaning, in the Boiler settings menu, set
the time of the burner operation without
cleaning after which the boiler will enter the
BURNING OFF mode, in which the
mechanism for rotary cleaning of the burner
will be started and then firing-up the burner.
Purification of the furnace is made during
FIRE UP and BURNING OFF. Parameter
Cleaning start time and Cleaning stop time
set the start and end time of the heat
exchanger cleaning. Additional parameters
responsible for cleaning are in the menu:
Service settings →Burner settings →
Cleaning
8.12 HUW settings
The regulator regulates temperature of the
silo of Hot Water HUW, providing that the
temperature sensor is connected. When the
sensor is disconnected –the information

13
about it is displayed in the main window. By
selecting:
HUW settings →HUW pump mode the
user is able to:
deactivate feeding the HUW container,
parameter Off,
setting HUW priority, by parameter
Priority –then CH pump is deactivated to
feed the HUW boiler quicker,
set simultaneous operation of CH and
HUW pump with the parameter No
priority.
8.13 HUW preset temperature settings
Preset temperature HUW is defined by
parameter:
HUW settings →HUW preset
temperature
8.14 Hysteresis of HUW
Below temperature HUW preset temp. minus
HUW hysteresis the HUW pump will activate
to feed the HUW container.
By small hysteresis value HUW
pump will activate faster after HUW
temperature decrease.
8.15 Enabling the summer function
To activate SUMMER function which allows
feeding the HUW container during summer,
without necessity to activate CH installation
and mixers periods, it is required to set the
menu:
Summer/Winter → SUMMER mode on
Summer.
Attention: when boiler operates
without heating buffer and the
controller is switched into Summer
function, than Standard mode
operation is recommended.
It is not allowed to activate
function summer when HW pump is
disconnected or damaged.
Summer function 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, you can set the parameters:
SUMMER mode act. temperature, so outdoor
temp. above which the summer mode will be
switched on and SUMMER mode deact.
temperature, so outdoor temp. below which
the SUMMER mode will be switched off.
8.16 HUW container disinfection
The controller can automatically, periodically
make HUW container warm up to 70ºC. 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 hot water.
Once a week at night, in Monday at 2 a.m.
the controller increases temperature of HUW
container. After 10 minutes of keeping the
silo at 70ºC the HUW pump is deactivated
and the silo returns to its normal operation.
It is not advisable to activate disinfection
function while the service of HUW is
deactivated.
8.17 Mixer circle settings
Settings for the first mixer circuit can be
found in the menu:
Mixer 1 settings
Settings for other mixers (after connecting
additional module B and C) can be accessed
in next menu items and they are identical for
each circuit.
Settings for mixer without weather
temp. sensor
It is necessary to manually set the required
water temperature in the heating mixer
circuit using parameter Preset mixer
temperature, 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. 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.

14
Settings for mixer with weather temp.
sensor without room panel
Set parameter Mixer weather control to On.
Select weather curve as per point 8.18.
Using parameter Heating curve shift, set
preset room temperature following the
formula:
Preset room temperature = 20°C + heating
curve shift.
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.
Mixer settings with weather temp.
sensor and room panel settings
Set parameter Mixer weather control to On.
Select weather curve as per point. 8.18. The
room 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 described in point. 8.18
it may be necessary to fine-tune the heating
curve shift.
In this setup, the 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 room panel) = 22°C. Temperature
measured in the room (by room panel) =
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.
Attention: setting too high value of room
temperature factor may cause cyclic room
temperature fluctuations.
8.18 Weather control
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:
Service Settings →Boiler settings →
Thermostat select. = Off
If a room panel is connected, it is also
necessary to set the parameter Room
temperature 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

15
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 Heating 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 Heating 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
In the controller it is possible to set time
periods of silo temperature reduction,
heating cycles, hot water silo, circular pump
and boiler. Time periods allow setting
temperature reduction in given time period –
e.g. 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. Decrease of preset
temperature in selected time intervals is
indicated by the symbol on the main
screen. To activate time intervals, set the
parameter Night time decrease for the given
heating circuit to ON. The parameter
Reduction value 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 30 min.
Time periods
In the given example, the regulator will set
the decrease of preset temperature by
Reduction value 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 Reduction value 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 Reduction value from 22:00 to
23:59.
Attention, defining time periods
during one day must be started at
00:00.
Time period is omitted by setting
period reduction for value “0” even if
scope of hours is set in it.
8.20 Working according to schedule
In the regulator is possible to switch on and
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. To activate the time intervals
must set the parameter Off,in the menu:
Operation with schedule at YES. Switching
on and off the boiler in the time interval can
be set for all on separate days of the week in
the Schedule.
8.21 Control of the circulation pump
Functionality of circular pump is available in
the menu:

16
HUW setting →Night time decrease circ.
pump
and
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 Circulating
operation time, what Circulating standstill
time.
8.22 Fuel level configuration
To operate the fuel level in the tank, the
regulator uses a fuel level sensor. After
burning fuel below the minimum level set in
the sensor by the boiler manufacturer, the
regulator will display a reminder "CAUTION!
Low fuel level" and it will continue to supply
fuel. If the user does not add fuel, the
regulator burns all the fuel and switches off
the boiler.
If the fuel level sensor is not used, the fuel
level will be operated in accordance with the
following description.
Operation of fuel level indicator
To activate displaying fuel level following
parameters are to be set:
Boiler setting →Fuel level →Alarm level
on value bigger than “0”, e.g. 10%.
By pressing on the left or right window of the
main window you can select the fuel level
indicator. Tip: fuel level can also be seen in
room panel.
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:
„Set fuel level to 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
the value of the parameter:
Boiler settings →Fuel level → Fuel level
calibration →Fuel Level 0%
8.23 Feeder efficiency test
The regulator allows you to test the
efficiency of the burner feeder, which has a
significant impact on the operation of the
burner. The test is started with the Feeder
test parameter in the menu:
Boiler settings →Feeder
During the test, a necessarily filled feeder
feeds fuel to an additional container for the
time set in the Efficiency test time. After this
time, weigh the fuel in an additional
container and enter the value obtained in the
parameter Fuel dose from test.
In case of emptying the main fuel tank and
restarting the boiler / burner, the filling

17
function of the burner feeder should be
enabled by the parameter Feeder filling.
8.24 Information
Menu information enables view to measured
temperatures and allows to check which of
devices are currently activated.
After connecting extension module
of mixers information about
auxiliary mixers are displayed.
8.25 Manual control
In the regulator it is possible to manual
activate devices like e.g. pumps, feeder
engine, or blower engine. It enables to check
if the device is operating correctly and if it is
connected properly.
Entering manual control is possible
only in “Boiler Off”mode, when silo
is switched off.
Description: OFF –the device is turned off, ON –the
device is turned on.
Attention: long lasting activating of
fan, feeder or other device may
cause danger.
8.26 Menu favorites
In the menu bar at the bottom of the screen
is visible button . After its selecting
appears quick selection menu. Elements of
this menu is added by hold for a moment the
appropriate icon in the rotary menu.
To remove an item from the menu favorites
being in the favorites menu hold the selected
icon and then confirm the deletion.
8.27 Room thermostat and panel
The regulator can cooperate with wired
(ecoSTER200, ecoSTER TOUCH) room panels
or (eSTER_x40, eSTER_x80) wireless room
panels - two-way ISM radio transmission. All
panels has a built-in room thermostat. This
room panels shows useful information such
as: fuel level, alarm indication etc.
8.28 Cooperation with the Internet
