2GENERAL INFORMATION
The controller is a modern electronic device
designed to handling the work of the pellet
boiler using help of optical flame brightness
sensor. The device is compactly build, easy
to install.
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 one)
The controller can cooperate with additional
steering panel located in living rooms and
additional modul of lambda λsensor.
Handling of the controller is easy and
intuitive. The controller can be used within
the household and in small industrial
buildings.

8.2 BOILER START UP - Switching on
and off of the boiler
After making sure that fuel is in the silo, and
the hatch is closed –the boiler can be
switched on. To activate boiler press the
screen “Boiler activated”, then “Activate
controller?” sign will appear.
Pic. 2 Boiler start up
After accepting, boiler will go into firing up
mode. There is another way to activate
boiler, Press MENU and then find and press
in round menu button: .
To switch off the boiler press MENU button
and then find and press button: .
Attention: the controller will go to burning off
process. Right after its finish a sign will
appear: “boiler switched off”.
8.3 BOILER PRESET TEMPERATURE
SETTINGS
The preset boiler temperature and preset
circuits temperature can be set in the menu
(Possible temperatures are restricted with
range of respective service parameters of the
controller).
Boiler settings →Preset boiler
temperature
Mixer settings 1-5 →Preset mixer
temperature
Value of parameter: The preset boiler
temperature, is omitted by the controller
when preset boiler temperature is controlled
by weather sensor. Independently, the
preset boiler temperature is automatically
raised in order to load the HUW buffer and to
load heating circuits of mixers.
8.4 FIRING UP
FIRING UP mode is for automatic firing up of
furnace in boiler. Total time of firing up
process is depended on controller’s settings
(feeder operation time, heater operation
time, etc.) and on boiler’s condition before
firing up. Parameters influencing firing up
process are in the menu:
Service settings →Burner settings→
Burning up
In case of failed attempt of firing up the
furnace, another attempts are taken during
which amount of fuel (feeding time) is
reduced to 10% of first attempt’s dose.
Another attempts of firing-up are numbered
next to the symbol of an igniter .
After three failed firing up attempts an alarm
Failed 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 WORK
The fan operatres constantly –see Pic. 3 Fuel
feeder is engaged periodically. One period
consists of feeder operating time and pause
in feeding time.

If the boiler’s temperature reaches preset
one then the controller switches of to
SUPERVISION mode.
Controller is equipped with boiler’s power
modulation mechanism –which allows for
gradual power reduction when approaching
the preset temperature.
There are three power levels:
- Maximal power 100
- Medium power 50
- Minimum power 30
Values for the individual power levels can be
set in the menu:
Service settings → Burner settings →
Operation
The controller regulates burner’s power with
which it operates depending on preset
temperature and defined hysteresis
Hysteresis H2 and Hysteresis H1. Pic. 4
Hystereses H1 and H2 of power modulationIt
is possible to configure volumes H1 and H2
in such a way that modulation is done
without intermediate position. That means
switching from 100% to 30% with omission
of 50% power.
Pic. 4 Hystereses H1 and H2 of power modulation
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
Hysteresis H2 and Hysteresis H1 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 adjustment of Hysteresis H2 and
Hysteresis H. It also allows for quicker reach
the preset temperature.
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 5
C degrees the controller switches into
SUPERVISION mode.
8.6 SUPERVISION
SUPERVISION mode is applicable either in
regulation in STANDARD and Fuzzy Logic
mode.
The controller switches into SUPERVISION
mode automatically without user’s
intervention: - in Standard regulation mode
–after reaching the boiler preset
temperature, - in Fuzzy Logic steering –after
exceeding boiler preset temperature by 5 C
degrees.
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
menu:
Service settings →Burner settings →
Supervision
Maximum time of boiler’s operating in
supervision mode is defined in 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.

13
8.7 BURNING OFF
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 menu:
Service settings →Burner 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 PAUSE mode.
8.8 PAUSE
In PAUSE 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 (Temperature when
start buffer feeding).
8.9 CHIMNEY SWEEP
The regulator has a special CHIMNEYSWEEP
mode. In this mode, the time set in Chimney
sweep mode work time are activated
together all the heat consumers in the
heating system, and boiler begins to warm
up to the preset power set in:
CHIMNEY SWEEP mode →Chimney
sweep mode preset power
This mode is used for testing and adjusting
the operation of the boiler.
8.10 GEATE
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:
Boiler settings →Boiler work mode
from "pellet" to "grate". In the grate mode
fuel feeder is turned off. The combustion
process is regulated by the fan. Fan power,
when working with grate, is set in:
Boiler settings →Power modulation →
Blowing power –Grate
The values of parameters such as:
Boiler settings →Preset boiler
temperature
Boiler settings →Power modulation →
Boiler hysteresis
Service settings →Burner settings →
Fuel detection time
are individually adjusted for the "grate". 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
→Temperature of activating the CH
pump
and then for a period of 10 minutes there
has been no growth.
8.11 HUW SETTINGS
The controller regulates temperature of the
silo of Hot Water HUW, providing that the
temperature sensor is connected. When the
sensor is disconnected –the information
about it is displayed in the main window. By
selecting:
HUW settings →HUW pump working
mode the user is able to:
Deactivate feeding the silo, parameter
Deactivated,
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,
Activate function Summer.
8.12 HUW TEMPERATURE SETTINGS
Preset temperature HUW is defined by
parameter:
Settings of HUW →Pre-set HUW
temperature
8.13 HUW HYSTERESIS
Below temperature Preset temperature of
HUW –Hysteresis of HUW container the HUW
pump will activate to feed the HUW silo.

14
By small hysteresis value HUW
pump will activate faster after HUW
temperature decrease.
8.14 ACTIVATION SUMMER FUNCTION
To activate SUMMER function which allows
feeding the HUW tank during summer,
without necessity to activate CH installation
and mixers periods, it is required to set the
SUMMER mode for Summer.
Summer/Winter SUMMER mode
In SUMMER mode, all heat
consumers can be switched off so
before turning it on, make sure
that the boiler will not overheat.
If the weather sensor is connected SUMMER
function can be activated automatically with
the Auto parameter with additional settings
at which the function is to be switched on /
off depending on the outside temperature of
the set parameters: Activated temperature
SUMMER, Deactivated temperature SUMMER.
8.15 HUW DISINFECTION
The controller can automatically, periodically
make HUW silo 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 HUW hot
water.
Once a week at night between Sunday and
Monday at 2 a.m. the controller increases
temperature of HUW silo. 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.
8.16 MIXER CIRCLE SETTINGS
Settings of first mixer circle are in the menu:
Menu →Mixer settings 1
Settings for other mixers are in following
sections of the menu and are identical in
each cycle.
Mixer settings without weather sensor
It is required to set manually desired
temperature in mixer’s heating cycle using
parameter Preset temperature of mixer, e.g.
50ºC. Such should be a value to provide
required room temperature.
After connecting a room thermostat, value of
decline in preset mixer temperature from
thermostat should be set. (parameters Mixer
room thermostat e.g. 5ºC. This value should
be chosen experimentally. A room
thermostat can be a traditional one or a
room panel Room Control TOUCH. After
activating the thermostat, mixer preset
temperature will be reduced. When this value
is reduced correctly then room temperature
increase will be stopped.
Mixer with weather sensor setting
without room panel Room Control
TOUCH
Set parameter Weather control of mixer in
position on. Adjust weather curve according
to point 8.17
Using parameter Parallel movement of curve
set required room temperature according to
formula:
Required room temperature = 20°C +
heating curve parallel movement.
Example.
To reach room temperature 25°C value of
heating curve movement must be set for
5°C. To reach room temperature 18°C value
of heating curve parallel movement must be
set for -2°C.
In this configuration a thermostat can be
connected. It will level inaccuracy of heating
curve adjustment in case when its value will
be too big. In such case value of decrease of
preset mixer room temperature from
thermostat should be set i.e. for 2°C. After
disconnecting thermostat plugs preset mixer
cycle temperature will be reduced. By correct
adjustment of this reduction will stop
temperature increase of temperature in
heated room.
Mixer with weather sensor and room
panel Room Control TOUCH settings
Set parameter Weather control of mixer. In
position off.
Adjust weather curve according to point 8.17

15
Controller Room Control TOUCH
automatically moves the heating curve
depending on preset room temperature. The
controller relates adjustments to 20ºC, i.e.
for preset room temperature = 22ºC the
controller will move heating curve by 2ºC, for
preset room temperature = 18ºC the
controller will move heating curve by -2ºC. In
some cases described in point 8.17. It can be
necessary to adjust heating curve
movement.
In this configuration room thermostat Room
Control TOUCH is able to:
- reduce temperature of heating cycle by a
constant value, when preset temperature in
a room will be reached. Similarly like it was
described in previous point (not
recommended), or
- automatically, constantly correct heating
cycle temperature.
It is not recommended to use both these
possibilities at the same time.
Automatic correction of room temperature is
done according to formula:
Correction = (preset room temperature –
measured room temperature) x Room
temperature ratio / 10
Example.
Preset temperature in heating room (set in
Room Control TOUCH) = 22ºC. Measured
temperature in room (using Room Control
TOUCH) = 20ºC, Room temperature ratio =
15
Preset mixer temperature will be increased
by (22ºC –20ºC) x 15/10 = 3ºC. Correct
value of parameter must be found Room
temperature ratio. Scope: 0…50. The bigger
value of factor the bigger correction of preset
boiler temperature factor. When set on value
“0” preset mixer temperature is not
corrected. Attention: setting too high value
of room temperature ratio may cause cyclic
room temperature fluctuations.
8.17 WEATHER CONTROL
Depending on measured outside
temperature, automatically controlled can be
either preset boiler temperature and mixer
cycles temperatures. By correct adjustment
of heating curve temperature of heating
circuits is counted automatically depending
on value of external temperature. Thanks to
that by choosing proper heating curve for
given building, room temperature remains
approximately the same –no matter what
outside temperature.
In case of connected room panel Room
Control TOUCH set additionally room
temperature ratio = 0
Guidelines for correct heating curve settings:
- floor heating 0,2 -0,6
- radiator heating 1,0 - 1,6
- buffer 1,8 - 4
Pic. 5 Heating curves.
Tips for choosing proper heating curve:
If by falling outer temperature room
temperature is increasing, then value of
chosen heating curve is too big,
If by decreasing outer temperature, room
temperature is also decreasing, then value of
chosen heating curve is too low,
If by frosty weather room temperature is
appropriate and in warmer time is too low –
it is recommended to increase parameter
Parallel movement of heating curve and then
choose lower heating curve,
If by frosty weather room temperature is too
low and in warmer time too high –it is
recommended to reduce Parallel movement
of heating curve and choose higher heating
curve.
Buildings which are poorly isolated require
setting heating curve with higher values, and
for better isolated buildings heating curve
will have lower value.

Preset temperature, counted according to
heating curve can be decreased or increased
by controller when it goes beyond scope of
limits of temperatures for given cycle.
8.18 NIGHT DECREASE SETTINGS
DESCRIPTION
Night time decreases for boiler, heating
circuits, HUW tank 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. Decrease of preset boiler
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 boiler or
the given heating circuit to On. The
parameter Reduction value set the temp. the
reduction, one for all time intervals.
Decrease night can be defined separately for
every day of the week set Schedule.
Select the lowering of the temperature set
point and the beginning and end of a given
time interval.
8.19 CIRCULAR PUMP CONTROL
Functionality of circular pump is available
after connecting to Output H controller or
additional module C.
Should be set the support Outputs H1 or
Output H2 and H3 to support the circulation
pump in:
Service settings →Output H1, Output H2
and H3
Settings are in:
Settings of HUW →Night reductions of
circulation 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. The circulation pump is running
in the Circulation running time in the periods
which have not been mentioned above.
8.20 FUEL LEVEL CONFIGURATION
Fuel level indicator activating
To activate displaying fuel level following
parameters are to be set
Boiler setting →fuel level →alarm level
On value bigger than “0”, i.e. 10%
Touching left or right window in main window

standard option of the controller).
Fuel level indicator service
Each time when fuel silo is filled to required
level it is necessary to press and keep the
current fuel level in main window. Following
info will appear:
Pic. 6 Fuel level service.
After choosing and accepting „YES” fuel level
will be set for 100%. Attention: Fuel can be
refilled anytime, that means it is not needed
to wait till the silo is empty. However fuel
should be filled up to the level corresponding
to 100% and set the controller level as
described above.
Description of activity
The controller measures fuel level on the
basis of its current consumption. Factory
settings will not always correspond to actual
fuel consumption , so to work correctly this
method needs level calibration by controller’s
user. No additional fuel sensors are required.

Calibration
Fill the silo to the level which corresponds to
full level of fuel, then set value of parameter:
Boiler settings →Fuel level →Calibration
of fuel level →fuel level 100%
In main window the indicator will be set on
100%. The calibration process is marked
with a pulsating fuel level indicator. The
indicator will pulsate until programming point
referring to minimum fuel level. Decreasing
level of fuel in the silo should be monitored
constantly. When fuel level reaches expected
minimum, parameter value should be set this
way:
Boiler settings →Fuel level →Calibration
of fuel level →Fuel level 0%
8.21 COOPERATION WITH
ADDITIONAL FEEDER
After connecting additional B module the
controller can cooperate with low fuel level
sensor in silo. After activating sensor , for
Additional feeder working time controller will
connect auxiliary feeder to refill basic fuel
level. This parameter can be found in:
Service settings →Burner settings →

8.22 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.
8.23 MANUAL CONTROL
In the controller it is possible to manually
activate devices like i.e. pumps, feeder
engine, or blower engine. It enables to check
if the device is operating correctly and if it is
connected properly.
Attention: Entering manual control
is possible only in STAND-BY mode,
when boiler is switched off

Long lasting activating of fan,
feeder or other device may cause
danger.
8.24 MENU FAVORITE
In menu, on a lower stripe of the screen
there is a button: . After its
selection fast choice menu appears. Parts in
this menu are added by pressing for a while
the right icon in a round menu.
To delete selected position from favorites
menu it is needed to press it for a longer

TOUCH or standard room thermostat, 14 –return temperature sensor (is not necessary to operate the
system).
To improve water circulation in gravity cycle it is necessary to use large nominal profiles
DN of a pipe and 4 way valve, not to use large amount of knees and profile narrowings.
Use other rules referring to gravity installations. If return sensor is installed closely, it is
necessary to isolate it thermally from surroundings and improve thermal contact with
pipe. Preset silo temperature must be set so high to ensure thermal power for mixer cycle
when at the same time heating water returning to the silo.
