1 RECOMMENDATIONS 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.

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.

 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 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.

 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.

2 General

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 read­out. 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.

switched on. To start the boiler - press
BURNER OFF? at any place on the screen.
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.

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

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

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)

symbol .

10

Note: If only the HUW is heated
(summer mode), it is recommended
to set the regulator to Standard
mode.

Parameters should be so selected
that the boiler temperature in this
mode gradually drops. Incorrect
settings may lead to boiler
overheating.

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.

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.

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.

When the supervision time expires, the
regulator switches to EXTINGUISHING mode,
unless the boiler temperature decreases and
the boiler 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

Keep the tenants informed of
activating the disinfection function
as there is risk of being burnt with
hot usable water.

In low hysteresis values, the HUW
pump will start faster when the
HUW temperature drops.

In Summer mode, all heat
receivers may be shut off, so
before enabling it please make
sure that the boler does not
overheat.

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.

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

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.

8.12 HUW Circulation

The settings are located in:

HUW Settings→Circulation pump night
time decrease

and

Service Settings→ CH and HUW settings

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

12

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:

13

Mixer 1 settings → Mixer room therm.=

Note! Setting of time intervals for
24 hours (one day) should start
from 00:00!

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

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.

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.

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.

14

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

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.

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

9 Description 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.

8.21 Favourite menu

In Touch version in the menu bar at the
bottom of the screen there is a button:

9.2 Feeder max. temp. exceeded

This alarm will occur after the feeder

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.

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).

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!

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.

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.

9.5 Feeder temp. sensor failure

This alarm occurs when the sensor is
damaged or when its measurement range is
exceeded.

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.

9.6 Exhaust temperature sensor failure

This alarm occurs when the sensor is
damaged or when its measurement range is
exceeded.

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.

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

17

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.

13.1 Environmental conditions

Due to the risk of fire is prohibited to use the
controller in explosive gas and dust
enviroment (eg coal). Regulator should be
separated using appropriate enclosure.
In addition, controller cannot be used in the
presence of water vapor condensation and be
exposed to water.

13.2 Installation requirements

The regulator should be installed by a
qualified and authorised fitter, in accordance
with the applicable norms and regulations.
The manufacturer bears no responsibility for
damages caused by failure to observe this
manual. The regulator is to be built-in. The
regulator cannot be used as a stand-alone
device. The temperature of the ambient and
the fitting surface cannot exceed the range
of 0 - 50˚C. The device consists of two
modules: control panel and working module.
Both elements are connected with electric
wire.

12 Conditions of storage and

transport

The regulator cannot be exposed to direct
effects of weather, i.e. rain and sunlight.
Storage and transport temperature cannot
exceed the range of -15…65 °C.
During transport, the device cannot be
exposed to vibrations greater than those
typical of normal road transport.

13.3 Assembly of TOUCH control panel

The Control Panel is intended to be installed
in a mounting plate. Make sure there is
sufficient thermal insulation between the hot
walls of the boiler and the control panel and
wiring. The amount of space needed to
properly install the control panel is illustrated
below. Follow the guidelines below when
installing the Panel.

 Make an opening in the mounting plate

according to the following illustration.

23

Control panel mounting requirements. 1 –
control panel, 2 – vent holes to provide air
circulation (note: the holes may not cause
downgrading of required IP rating. They are
not required if permitted ambient
temperature around the control panel is not
exceeded.)

Disassembly of control panel:
To remove the control panel (1) from the
housing - insert flat elements (2) into
indicated slots to release housing catches
and remove the panel (1).

13.4 Mounting of working module

The executive module must be covered. The
cover must ensure a level of protection
relevant to the environment in which the
regulator will be used. Moreover, it must
prevent access to parts which are carrying
dangerous voltage, such as terminals. A
standard installation cabinet may be used as
the cover. In such case, the user has access
to the face plate of the executive module.
The cover may be composed from boiler
elements surrounding the whole module.
The module cover does not provide
resistance to dust and water. To protect it
from these factors, provide a suitable
additional cover.
The executive module is intended for
mounting on a standard DIN TS35 rail. The
rail must be installed tightly on a secure
surface. Before placing the module on the
rail (2), lift the pin (3) up. After placing the
module, press the pin (3) to its original
position. Make sure that the device is
installed securely and cannot be removed
from the rail without the use of tools.
For safety reasons, maintain a safe distance
between the active elements of the terminal
of the executive module and the conductive
(metal) elements of the cover (at least 10
mm).
The connection wires must be protected from
plucking it out and loosening, or covered in a
way that prevents the wires from tightening.

13.5 IP protection rate

Enclosure of the regulator’s executive
module provides various IP protection rates,
depending on the method of installation.
After enclosing in accordance with this
drawing, the device has protection rate IP 20
from the front side of the executive module
enclosure (specified on the rating plate).
From the side of the terminals, the casing
has protection rate IP00, thus the terminals
of the executive module must unconditionally
be enclosed, in order to prevent access to
this part of the casing.
If it is necessary to access the part with the
terminals, disconnect the mains supply,
make sure that there is no voltage on
terminals and leads, and remove the
executive module enclosure.

Sensor wires may be extended using wires of
cross-section area not less than 0.5 mm2.
Total length of wires of each sensor should
not exceed 15 m.
Insert boiler temperature sensor into
thermometer well fastened to boiler shell.
Fasten feeder temperature sensor to the
surface of feeder screw tube. Insert
temperature sensor of HUW container into
thermometer well welded to the container.
The best way to mount mixer temperature
sensor is to insert it into a sleeve located in
the stream of flowing water, however, it is
also allowed to fasten the sensor in a contact
manner provided that the sensor and the
pipe are properly heat-insulated.

Make sure thermal contact between the
sensors and the surface which temperature is
measured is good. Apply thermal paste to
improve the contact. Pouring sensors with oil
or water is not allowed. Sensor wires should
be separated from power supply wires.
Otherwise, temperature indications may be
erroneous. Min. distance between these
wires should be 10 cm.
Do not allow sensor wires to contact hot
parts of the boiler and heating system. Wires
of temperature sensors are heat resistant to
the temperature not exceeding 100°C.

Attach the sensor to the wall using tackbolts.
To access the tackbolts holes, unscrew the
sensor lid.

13.10 Checking temperature sensors

The temperature sensor can be checked by
measuring its resistance in a given
temperature. Replace the sensor if there are
significant differences between the measured
resistance and the values provided in the
table below.

13.9 Connecting weather sensor

The regulator cooperates only with a weather
sensor of the CT6-P type. The sensor should
be installed on the coldest wall of the
building, usually this is the northern wall,
under a roof. The sensor should not be
exposed to direct sunlight and rain. The
sensor should be fitted at least 2 m above
the ground, far from windows, chimneys and
other heat sources which could disturb the
temperature measurement (at least 1,5 m).
Connect the sensor using cable of 0,5 mm2
cross-section, up to 25 m long. Polarity of
the leads is insignificant. Connect the other
end of the cable to the regulator.

When connecting mixer servo,
take due care to prevent boiler
overheating, which may occur
when the flow of boiler water is
limited. You are advised to get
familiar with the position of the
valve corresponding to its
maximum opening before
commencement of work so that
you may ensure heat collection

15 SERVICE SETTINGS

Burner settings

Firing-up

 Ignition test time

Time of checking whether the burner is ignited. The regulator checks if
there was a proper rise (increase) of exhaust temperature. After
successfully completing the check, the regulator switches to
OPERATION mode.

 Feed time

Fuel dosage feed time at ignition.

 End-ignition exhaust temp.

Exhaust temperature above which the burner is considered to be ignited.
Ignition test is ignored. Note: setting a low temperature may result in
switching to OPERATION mode without a sufficient flame in the furnace.
Recommended value: 130-150 °C.

 Exhaust delta

Rise (increase) of exhaust temperature necessary to switch to
OPERATION mode.

 Ignition fan

Fan % at ignition. Note: setting a high value will prolong the ignition
process and result in failed ignition attempt.

 Ignition time

Time of consecutive ignition attempts. After this time, the regulator will
make another ignition attempt (max. 3 attempts).

 Fan time extension

Between each ignition attempt, the fan works without the heater. Thanks
to this, before making another ignition attempt, the possible flame in the
burner has a chance to increase the exhaust temperature and cause the
switch from IGNITION to OPERATION mode without the need for
additional ignition attempts.

 Heating-up time

Igniter heating-up time before switching on the fan. This should not be
set too high to prevent damage to the heater. After such time, the
heater continues to work until an increase in the exhaust temperature is
detected.

Operation

 OPERATION mode cycle time

Complete cycle time of fuel feeding in OPERATION mode. OPERATION
cycle time = OPERATION feed time + feeder standstill time

 Feeder efficiency

Efficiency of the fuel feeder in kg/h. Entered a measured amount of fuel
in constant feed (feeder working constantly). The parameter does not
affect the work of the burner and is used for calculating the fuel level and
current boiler output.

 Fuel caloric value

Fuel caloric value in Kwh/kg. This parameter is only used for information.
The parameter does not affect the work of the burner and is used for
calculating the fuel level and current boiler output.

 Container capacity

Fuel container capacity used for calculating the fuel level. Entering the
correct value relieves the user from the need to calibrate the fuel level.
The regulator uses this data if the fuel level has not been calibrated.
After calibrating the fuel level successfully, the regulator does not use
this parameter.

 Feeder

It is possible to conduct a feeder efficiency test and to set the duration of
this test. Additionally, fuel weight can be entered here. This data
facilitates the adjustment of fuel oriented parameters.

Burning off

BURNING OFF mode is not used when coal is the fuel of choice.

 Burning off time

Fan time in order to burn off remaining fuel.

 Purge speed

Fan speed during burning off in %.

Supervision

 Supervision time

BURNING OFF mode and then into PAUSE mode. When the parameter
Supervision time = 0, then the controller skip the SUPERVISION mode
and goes directly to BURNING OFF mode. When the parameter
Supervision time = 255, then the controller stays in SUPERVISION
mode until the boiler temperature drops down up to the level, by which
the controller returns to OPARATION mode.

15.1 BURNER

35

 Fan speed

Fan speed in SUPERVISION mode; too high value may cause the boiler
to overheat or the flame to return to the feeder; too low value results in
fuel over-filling.

 Feed time

Feed time in SUPERVISION mode; too high value may cause the boiler
to overheat or fuel over-filling; too low value results in fuel returning to
the container.

 Interval time

Feeder work cycle time in Supervision mode. SUPERVISION cycle time
= feed time + interval time

 Fan time extension

In SUPERVISION mode, after a fuel dose is supplied and the feeder is
off, the continues to work for the extension period in order to ignite the
fuel dose. This parameter should not be set too high as it may over heat
the boiler.

Min. Fan speed

Minimal fan speed in % that can be selected by the user of the regulator.
This parameter is used to limit the access to the complete fan speed
range in the user menu. It is not used in the fan control algorithm. The
parameter should be set relatively low, allowing the fan to spin slowly
and freely.

Lack of fuel detection time

Lack of fuel detection time is deduced after the exhaust temperature
drops below the Lack of fuel detection threshold. After this time is
deduced, the regulator makes 3 attempts to ignite the burner, and when
this fails, it displays the “ignition failed” alarm.

Lack of fuel detection
threshold

Exhaust temperature increase
time

This time is used as function preventing the extinguishing of flame in
OPERATION mode. If the exhaust temperature does not exceed the
Lack of Fuel Detection threshold after such time, an ignition test will be
made.

Max. feeder temp.

This parameter determines the maximum temperature at which the alarm
for exceeding the maximum feeder temperature is displayed. When this
temperature is exceeded, the feeder is engaged for a predefined time,
with a several-minute pause. If the temperature drops, the regulator
resumes normal operation; if not, the feeder will be engaged for a longer
period in order to remove embers from the feeding pipe. These times
may be edited in a special menu accessible only to the manufacturer of
the boiler.

15.2 BOILER

Boiler settings

Grate

 Max. ignition time

When this time is exceeded ant the exhaust temperature does not rise
above the Lack of Fuel detection threshold +15°C, a failed ignition alarm
will be displayed. Note: during ignition in RUST mode, the fan works at
the Ignition fan - grate speed. This parameter is adjusted via the user
menu.

 Purge operation - supervision

Fan purge time when the boiler temperature exceeds the boiler’s set
temperature

 Purge interval - supervision

Fan purge interval time when the boiler temperature exceeds the boiler’s

set temperature

 Lack of fuel detection time

When the exhaust temperature in OPERATION mode drops below the
Lack of fuel detection threshold, lack of fuel is detected and the fan is
stopped.

 Lack of fuel detection method

Only exhaust - lack of fuel detection occurs via the indications of the
exhaust temperature sensor. This method allows to detect the lack of
fuel quickly. It can only be used when there is an exhaust sensor in the
flue of the boiler.
Water and exhaust - lack of fuel detection occurs both via the indications
of the exhaust temperature sensor and the water temperature sensor in
the boiler. To detect the lack of fuel, both temperatures need to drop,
and the water temperature in the boiler must drop below the CH pump
activation temperature.

 Exhaust temperature - fan

reduction

In order to limit the chimney loss, the fan speed is reduced to the value
of Fan speed 30% This happens when the exhaust temperature

36

exceeds the Fan speed reduction temperature.

Return protection

 Return protection 4D

This parameter turns on/off the boiler return protection function, which is
being done by mixing valve together with electric actuator. Attention: do
not activate this function when there is no actuator installed on the valve!

 Return histeresis

The electric actuator will return to its normal operation with return
temperature ≥ min. return temperature + return hysteresis.

 Min. set return temperature

The boiler return temperature below which the electric actuator will close
the mixing valve.

 Valve closing percentage

It is a value for opening the mixing valve during active return protection
function. This value is given in percentage. This value should be set in
such way, that the return temperature can raise. Attention: the return
protection function will work only in case when the set boiler temperature
will be set on sufficiently high value, otherwise there will be too many
lock ups of the actuator. Attention: The valve is locking up with the +-1%
of precision.

Min. boiler temperature

Minimal set temperature for the boiler, that can be edited by the user in
user menu and also a minimal temperature, that can be automatically set
by a controller e.g. from night decrease, weather control etc.

Max. boiler temperature

Maximal set temperature for the boiler, that can be edited by the user in
user menu and also a maximal temperature, that can be automatically
set by a controller e.g. from night decrease, weather control etc.

Boiler cooldown temp.

Preventive boiler cooldown temperature. When this temperature is
exceeded, the regulator switches on the hot usable water pump and
opens the mixer circuits in order to cool the boiler down. The regulator
will turn the hot usable water pump when the temperature of this water
exceeds the maximum value. The regulator will not open the mixer circuit
when mixer control = floor activated.

Thermostat select

The following options are available:
deactivated (deactivates the effect of the room thermostat on the boiler’s
operation)
universal (enables a no/nc room thermostat on terminals 42-43,
recommended for thermostats with hysteresis below 1K)
ecoSTER (this option is available when the ecoSTER TOUCH room
panel is connected, the signals on the status of the thermostat are sent
from the room panel)

Pump shut-off from thermostat

Available options:
No (the CH boiler pump is not switched off when the room thermostat is
activated)
YES (the CH boiler pump is switched off when the room thermostat is
activated)

CH and HUW settings

CH Pump activation temperature

This parameter decides on the temperature of boiler pump activation. It
secures the boiler against retting, that can occur when the boiler is being
cooled down with cold water from the installation. Attention: deactivation

of boiler pump doesn’t guaranteed, that the boiler is secure against

retting and therefore corrosion. It is recommended to apply additional
automatics e.g. 4-way valve or 3-way thermostatic valve.

CH pump standstill when loading
HUW

It requires a HUW sensor to be plugged in. A prolonged HUW tank
loading can, with HUW priority activated, lead to excessive cooling down
of CH installation, because with these kind of settings the CH pump is
switched off. The parameter of pause time of CH pump preventing this
by periodic operation of CH pump while HUW tank loading. The CH
pump will after this time activate for fixed set time of 30s.

15.3 CH and HUW

37

CH pump standstill time from the
thermostat

When the temperature of the heated rooms is reached (the contact of
the room thermostat is open), the CH pump is stopped for the CH pump
standstill time from the thermostat, after which the CH pump operation
time from the thermostat is activated. Note: The following conditions
must be met in order to stop the pump via the room thermostat:

Boiler room thermostat selection ≠ deactivated
Pump shut-off from thermostat = YES

CH pump standstill time from the
thermostat
Min. HUW temperature

It requires a HUW sensor to be plugged in. This parameter can be used
for limitation of possibility to choose too low value of HUW set
temperature.

Max. HUW temperature

It requires a HUW sensor to be plugged in. This parameter decides on
which maximum temperature will the HUW tank be heated during
dropping down excessive heat in alarm states. It is a crucial parameter
because setting this for too high value can lead to the risk of users
scalding with utility water. On the other hand, too low value of this
parameter can lead to a situation, when during boiler overheating there
will be no possibility to drop down excessive heat into the HUW tank.
When projecting the HUW installation, there should be an assumption of
controller malfunction. This situation can lead to dangerous level of HUW
temperature, leading to user scalding. It is advised to use additional
security precautions in form of thermostatic values.

Boiler temperature increase from
HUW and Mixer

This parameter determines the increase of the set boiler temperature in
order to load the HUW tank, buffer, and the mixer circuit. The
temperature is only increased when there is a need to do so. When the
set temperature of the boiler is on a satisfactory level, the regulator will
not change it in order to load the HUW tank, buffer, or mixer circuit. The
increase of the set boiler temperature for the period of loading the HUW
tank is signalled with the letter “C” in the main window of the display.

HUW operation extension

Available after connecting a HUW sensor. When the HUW tank is fully
loaded and the HUW pump is switched off, the boiler may be in danger
of overheating. This occurs when the set HUW temperature is higher
than the set boiler temperature. The problem is particularly prominent

when the HUW pump works in “SUMMER” mode and the CH pump is

deactivated. In order to cool the boiler down, the HUW pump operation
can be extended by the HUW operation time time value.

Circulation pump standstill time

It is the time between periods of circulation pump operation and it is
defined by the parameter circulation standstill time (recommended
setting is between 15-40 min.) The circulation pump is operating in
cycles for the time of circulation operation time (recommended setting is
between 60 and 120s.)

Circulation pump pperation time

Exchanger

It comes only for hydraulic installations with heat exchanger between
open and closed circuit. Available options are:
YES (the boiler pump is operating constantly in short circuit boiler – heat

exchanger, it is not excluded e.g. from “SUMMER” function or HUW

priority)
NO (standard operation of boiler pump)

Buffer settings

Activation

This parameter is used to turn on operation with the buffer. It is
available after connecting an additional B module and buffer
temperature sensors.

Loading start temperature

The parameter Loading Start temperature defines the upper buffer
temperature below which the process of buffer loading is being
started. This process will then be finish when the bottom buffer
temperature will reach defined temperature in the parameter Loading

Loading stop temperature

15.4 BUFFER

38

Stop temperature.

Central heating installation
activation

If the top buffer temperature drops below this value, in order to save
electrical power, the mixer pumps and HUW pumps will be
deactivated. This function is particularly useful when working in
GRATE mode.

15.5 MIXER

Mixer 1-4 settings

Mixer suport

 Off

The mixer actuator and pump are not in operation.

 CH On

It is being used when a mixing circuit is loading a heat installation of
CH. The maximum mixing circuit temperature is not being limited, the
mixer is fully opened during alarms e.g. with boiler overheating.
Attention: do not use this option when the heat installation is made
with pipes not resistant for high temperatures. In such cases it is
recommended to set the mixer operation for FLOOR switched on.

 Floor On

It is being used when the mixer circuit is loading floor heating
installation. The maximum mixer circuit temperature is limited to the
value of max. mixer set temperature.
Attention: after choosing the option – FLOOR switched on the
parameter of max. mixer set temperature should be so edited, that the
floor heating will be not damaged and there would be no danger of
scalding.

 Pump Only

By the moment when the mixer circuit temperature exceeds the set
temperature in the parameter mixer set temperature, the mixer pump
supply will be shut down. When the circuit temperature will drop by

2˚C then the pump will again be switched on. This option is usually be

used for control of floor heating pump in situation, when this pump is
operating together with thermostatic valve without actuator.

Thermostat select*

Options to choose from:
Shut down: (it cuts the influence of room thermostat upon the boiler
operation.)
Universal: (it turns on the no/nc room thermostat coupled to 42-43
contacts, it is required to use thermostats with 1K hysteresis.)
ecoSTER: (this option is available after remote control device
ecoSTER TOUCH is being connected, thermostat signal is being send
from room panel.)

Minimum mixer temperature

It is the parameter used for limitation of choosing too low value of set
mixer circuit temperature by the user. Automatic regulation (e.g.
periodic temperature reduction) also does not cause the reduction of
set temperature value below the value given in this parameter.

Maximum mixer temperature

This parameter has two functions:
_ it enables the limitation of choosing too high value of set mixer
temperature by the user. Automatic regulation (correction upon
heating curve, that comes from outside temperature) also does not
cause crossing the set temperature above the value given for this
parameter.
_ when the Mixer Support = On, then the mixer pump will shut down

by max. mixer temperature +5˚C, which protects the floor against

destruction. For the floor heating it should be set for the value below
45+/-50 ˚C or even lower, when the thermal resistance of this floor is
lower. Attention: setting too lower value of this parameter can lead to
unnecessary shut down of the pump.

Valve opening time

The time of valve full opening should be entered – this time can be
read from the nameplate of valve actuator, e.g. 140s.

Proportionality range

This parameter affects the movement of the mixer actuator. Increasing
this value results in the mixer reaching the set temperature faster.
Setting this parameter to excessive values causes deregulation of the

39

temperature and unnecessary actuator movement. The proper values
is set experimentally. It is recommended to set this parameter in the
range of 2-6 [3].

Constant for integration time

The greater the value of this parameter, the slower is the actuator
reaction for temperature deviation. Setting too lower values can lead
to unnecessary actuator movements, too high value extending the
time needed to find set value of the temperature. The right value is
being edited according to research results. It is recommended to set
this parameter value between 100 and 180 [160].

Pump shut-off from thermostat

Setting this parameter to “YES” results in closing the mixer and

deactivating the mixer pump after opening the room thermostat
contact (the room is warm). This setting is not recommended because
the heated room may cool down too much.

Mixer insensitivity*

This parameter determines the value of temperature insensitivity
(dead zone) of the mixer control system. The regulator controls the
mixer so that the measured temperature in the mixer circuit sensor is
equal to the set temperature. In order to avoid frequent actuator
movements which can wear it down unnecessarily, the parameter
should only be regulated when the measured temperature of the mixer
circuit is lower or higher than the set temperature by a value
exceeding the mixer insensitivity.

15.6 H OUTPUT

H output

H1 output

There are option to choose from:
Reserve boiler – 46-47 output controls the reserve boiler,
Alarms – when an alarm occurs, output 46-47 is being activated,

H2 output*

B module

Reserve boiler**

This option appears, when an H1 output = reserve boiler, defines the
temperature of solid fuel boilers above which the reserve boiler will be
turn on or off. During buffer operation it also defines the buffer
temperature above which the reserve boiler will be turn on or off.

16 Software UPGRADE

Note: software may be upgraded
by authorised personnel only. All
electric shock preventive
measures must be applied!

Inserting a microSDHC card

To upgrade the TOUCH version software, use only microSDHC memory card. In this section,
software upgrade in the TOUCH version using memory card is described.

To upgrade the software, disconnect power
supply of the regulator and remove ecoTOUCH
control panel from the regulator housing.
Insert memory card into indicated slot.
Memory card should contain new software
stored in the *.pfc format (two files: one with
software for control panel, and the other one
with software for module "A" of the regulator).
Upload new software directly to the memory
card. Do not nest data in sub-directory. Re­install the control panel in regulator housing

and connect power supply. Enter:

General Settings → Software Upgrade and upgrade the software: first in the A module, then
in regulator's control panel.

measure! Apply other methods
too. Regulator manufacturer is not
liable for anti-freezing related
damages.

the regulator is turned off, via keyboard
(regulator in STAND-BY).

17.1 Power supply decay

In the cases of power supply failure, the
regulator will resume the operation mode in
which it was before the failure.

17.2 Anti-freezing protection

In case the boiler temperature has fallen
below 5 C, CH pump is activated to force
boiler water circulation. It delays water
freezing process, but in case of very low
temperature or lack of power it may not be
sufficient to protect the equipment from
freezing.

17.3 Function of protecting pumps

against stagnation

The regulator protects the CH, HUW and
mixer circuit pumps against stagnation. It
does so by activating them periodically
(every 167 h for several seconds). This
protects the pumps against immobilization
due to sedimentation of boiler scale. For this
reason, the regulator power supply should be
connected also when in the boiler is not in
use. This function can be enabled also when

17.4 Bunker feeder

After connecting an additional B module, the
regulator can cooperate with the low fuel
level sensor in the container (fuel supply
from the bunker). After the senor activates
(the contact opens), the regulator will
activate the additional feeder for an
additional feeder operation time, in order to
refill the fuel container. This parameter is
found in:

Service settings→Burner settings

If the Additional feeder operation time is set
to zero, the additional feeder is deactivated.

17.5 Replacement of mains fuse

Mains fuses are located in each working
module. They protect the regulator and other
connected equipment. In case of
replacement, use 6.3 A, 5x20mm ceramic
time fuse. To remove the fuse, press down
fuse holder using flat screwdriver and turn it
in CCW direction.

17.6 Replacement of control panel

It is not recommended to replace only the
control panel as the software in the panel
must be compatible with the software in the
rest of the regulator.
