1 Safety requirements

Requirements concerning safety are
described in detail in individual chapters of
this manual. Apart from them, the following
requirements should in particular be
observed.

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.

 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 misused.

 The regulator is designed to be

enclosed.

 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 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.

 In the regulator there is applied

electronic disconnection of connected
devices (2Y type of operation
according to PN-EN 60730-1) as well
as micro-disconnection (2B type of
operation according to PN-EN 60730-

1).

 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.

 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

2 General information

Boiler regulator ecoMAX860P TOUCH is a
modern electronic device intended to control
boiler operation with automatic feeding of
solid fuel and with the ignitors. Flame is
detected via the exhaust temperature
sensor.
The regulator is a multipurpose device:

 it automatically maintains a preset boiler

temperature by controlling the fuel
combustion process,

 it controls timing fuel feeder and fan

(modulating its power),

 it automatically stabilizes a preset

temperature of the domestic hot water
container,

 it automatically maintains preset

temperature of several independent

mixer heating cycles.
The preset temperature of heating cycles and
the boiler can be set on the basis of a
weather sensor readouts.
The device includes the control panel with
horizontal regulation of its position, the main
operating unit and optional modules to
control additional heating circuits.
The regulator can cooperate with an
additional room panel ecoSTER TOUCH
situated in living quarters and module for the

8.2 Switching on/off the boiler

Make sure fuel is present in the tank and
tank hatch is closed. Now boiler may be
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 start­up. Press MENU button and find and press

If firing up the furnace fails, further attempts
are carried. Consecutive attempts are
visualised by numbers next to the lighter

symbol .
After three unsuccessful attempts, an alarm
Failed firing up attempt is reported. In such
case, the boiler operation is halted. Boiler
operation cannot be continued automatically

- service crew must intervene. After
removing causes of impossibility to fire up,
the boiler must be restarted.

8.5 OPERATION

The fan operates continuously. Fuel feeder is
activated cyclically. A cycle consists of feeder
operation time and duration of feeding
interval
Parameters related with the Operation mode
are: Feeder operation time and Fan output
in:

Boiler settings → Output modulation

button in pie menu.

To stop the boiler - press MENU button, and

find and press button in pie menu.

8.3 Settings preset temperature

Preset boiler temperature or preset HUW
temperature, just like the preset mixer
circuit temperature, can be set in the menu:

Boiler settings → Preset boiler temp.
HUW settings → HUW preset temp.
Mixer 1-4 settings → Preset mixer temp.

The value set as Preset boiler temp. is
ignored by the regulator if the preset boiler
temperature is controlled by weather sensor.
Regardless of that, the preset boiler
temperature is automatically increased in
order to fill the hot utility water tank and
feed heating mixer cycles.

8.4 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

8.6 Regulation mode

There are two regulation modes for
stabilizing the set temperature of the boiler:
Standard and FuzzyLogic

Boiler settings → Regulation mode

Operating in Standard Mode

When the boiler temperature reaches its set
value, the regulator switches to
SUPERVISION mode.
The regulator has a boiler output modulation
mechanism allowing it to gradually reduce
the output as the boiler temperature nears
its set value
Three boiler output levels can be set:
maximum, medium, and minimum. Each
level can be additionally adjusted with
individual fuel feeding times and fan speeds,
affecting the actual output of the boiler. The
output level parameters are accessible
through the menu
Boiler Settings → Output modulation.
The regulator sets the current output of the
burner depending on the set temperature of
the boiler and H1 and H2 hysteresis settings
It is possible to set the H1 and H2 values to
modulate the output withouth the medium
power stage, ie. reducing output from 100%

10

to 30%, skipping the 50% output (right side

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.

of the figure below).

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.

When the supervision time expires, the
regulator switches to BURNING OFF 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.

After the set temperature is exceeded by
5ºC, 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.

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 Buffer loading start
temperature.

8.10 Domestic hot water settings

HUW

The device controls temperature of the
domestic how water - HUW – tank, provided
that a HUW temperature sensor is
connected. If the sensor is disconnected, an
information about lack thereof is displayed in
the main window. The parameter:

Menu → HUW settings → HUW pump
mode allows the user to:

 disable filling of the tank, parameter Off,

11

 set HUW priority, using the Priority

After setting a low hysteresis value,
HUW pump will run faster when
HUW temperature falls.

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

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

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.

8.11 Setting HUW preset

temperature

Preset HUW temperature is defined by
parameter:

HUW settings → HUW preset temp.

8.12 HUW container hysteresis

Below HUW preset temp. – HUW container
hysteresis starts HUW pump to load the HUW

container.

8.13 HUW circulation

The settings can be found in:

HUW Settings → Schedule - circulation
pumps

and

Service settings → CH and HUW settings

Setting of circulating pump control is
analogical to night decrease setting.
Circulating pump switches on in selected
time intervals. In disregarded time intervals
circulating pump will start and remain in
operation for the period of time set in
Circulating pump operation time , then will
stop and remain out of operation for the
period of time set in Circulating pump
standstill time.

8.14 Enabling the SUMMER function

In order to activate the SUMMER function,
which enables to load the HUW tank in the
summer, without the need for activating the
CH system and mixer cycles, set the
parameter SUMMER mode to Summer.

Summer/Winter → SUMMER mode

If the weather sensor is connected SUMMER
function can be activated automatically with
the Auto parameter including settings for

SUMMER mode act. temperature, SUMMER
mode deact. temperature.

8.15 Disinfection HUW container

The regulator has a function of automatic,
periodic heating of HUW container to 70°C to
eliminate bacterial flora from the HUW
container.

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.

8.16 Mixer circuits settings

Settings for the first mixer circuit can be
found in the menu: Mixer 1 settings
Settings for other mixers can be accessed in
next menu items and they are identical for
each circuit.

Settings for mixer without weather
sensor

It is necessary to manually set the required
water temperature in the heating mixer
circuit using parameter Preset mixer temp.,

e.g. at a value of 50°C. The value should

allow to obtain the required room
temperature.
After connecting room thermostat, it is
necessary to set a value of decrease in
preset mixer temperature by thermostat
(parameters Mixer room therm.) e.g. at 5°C.
This value should be selected by trial and
error. The room thermostat can be a
traditional thermostat (NO-NC), or room
panel ecoSTER TOUCH. Upon activation of
the thermostat, the preset mixer circuit
temperature will be decreased, which, if
proper decrease value is selected, will stop
growth of temperature in the heated room.

12

Settings for mixer with weather sensor
without room thermostat ecoSTER
TOUCH

Set parameter Mixer weather control to On.
Select weather curve. Using parameter
Curve translation, set preset room
temperature following the formula:

Preset room temperature = 20°C + heating

curve translation.
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

Set parameter Mixer weather control to On.
Select weather curve. 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 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 ecoSTER TOUCH) = 22°C. Temperature
measured in the room (by ecoSTER TOUCH)
= 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. Note: setting a value of the room
temperature coefficient too high may cause
cyclical fluctuations of the room temperature!

8.17 Weather controlled

Depending on the temperature measured
outside the building, both preset boiler
temperature and temperatures of mixer
circuits can be controlled automatically. If
proper heating curve is selected, the
temperature of the circuits is calculated
automatically, depending on the outdoor
temperature. Thus, if the selected heating
curve is appropriate for the given building,
the room temperature stays more or less the
same, regardless of the temperature outside.
Note: during trial and error selection of
appropriate heating curve, it is necessary to
exclude influence of the room thermostat on
regulator operation (regardless of whether
the room thermostat is connected or not), by
setting the parameter:

Mixer 1 settings → Mixer room therm. =

0.
If a room panel ecoSTER TOUCH 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

13

Guidelines for selection of appropriate

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

heating curve:

- if the outdoor temperature drops, and the
room temperature increases, the selected
heating curve value is too high,

- if the outdoor temperature drops, and the
room temperature drops as well, the selected
heating curve value is too low,

- if during frosty weather the room
temperature is proper, but when it gets
warmer - it is too low, it is recommended to
increase the Curve translation and to select a
lower heating curve,

- if during frosty weather the room
temperature is too low, and when it gets
warmer - it is too high, it is recommended to
decrease the Curve translation and to select
a higher heating curve.
Buildings with poor thermal insulation require
higher heating curves, whereas for buildings
which have good thermal insulation, the
heating curve can have lower value.
The regulator can increase or decrease the
preset temperature, calculated in accordance
with the heating curve, if it exceeds the
temperature range for the given circuit.

8.18 Description of night time decrease

settings

Night time decreases for boiler, heating
circuits, HUW container and circulation
pump operation.

The intervals can be used to define time
periods at which lower preset temperature
may be set e.g. for a night time or when the
user is not at home. This feature enables
automatic reduction of preset temperature
without compromising the heat comfort and
reduces 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
Schedule for boiler or 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.
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.

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

14

set the decrease by 3°C from 22:00 to

Time interval is disregarded when
its decrease is set to "0" even
though "from... to ..." values have
been entered.

Upon connection of mixers'
extension module, information
windows of additional mixers are
displayed.

Note: Access to manual control
menu is possible only in the STAND­BY mode, i.e. when the boiler is
OFF.

Note: Long-term operation of the
fan, the feeder or other working
equipment may lead to occurrence
of hazardous conditions.

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%

Calibration can be skipped if the Feeder
Efficiency and Tank capacity, parameters are

set correctly in: Menu → Service settings
→ Burner settings → Operation

"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

Due to fire risk it is forbidden to use the
controller in proximity of explosive gases or
dust. Moreover the controller cannot be used
in conditions of water steam condensation or
be exposed to effects of water.

12.2 Mounting requirements

Regulator should be installed by qualified and
authorized technician with observance of
applicable standards and regulations. The
manufacturer disclaims any liability for
damage caused by non-observance of
instructions specified in this manual. The
regulator is intended to build into other
equipment, and may not be used as a
stand-alone device.
Ambient temperature and temperature of
mounting base should be within the range of
0…+50˚C. The regulator is composed of two
modules: a control panel and an operating
unit, connected with electric wire.

11 Storage and transport conditions

The controller cannot be exposed to
immediate effects of atmospheric conditions
i.e. rain or sunrays. Temperature of storage
and transport should be within scope

-15…+65°C.
During transport the controller cannot be
exposed to vibrations bigger than typical for
transport of boilers as well as direct pressure
upon the clamp cover in order to protect the
STB capillary, which is situated inside the
clamp box for the controller version equipped
with STB device.

12 REGULATOR INSTALLATION

12.1 Environmental conditions

12.3 Module installation

The regulator casing does not provide dust
and water immunity. In order to provide the
protection from these factors the regulator
should be enclosed with a proper casing.
The regulator is to be enclosed – which
means the regulator should be screwed on to
the flat horizontal or vertical surface (e.g.
boiler housing, room wall). To screw on the
regulator use mounting holes and proper
screws. Location and spacing of mounting
holes are shown in the picture below. The
regulator must not be used as a free­standing device.

After installation make sure that the device is
properly mounted and it is impossible to
detach it from the mounting surface.

21

Opening of the boiler door or flue
leakiness cannot expose the
regulator directly to hot gases and
fire from the fireplace.

In case of using the version with
STB device before making the
montage and wiring it is strongly
recommended to take out the STB
capillary from inside the clamp box
using cable opening as described on
the picture below.

Attention! This capillary cannot
be smashed or bend with acute
angle.

1- Cable opening 2 – The STB capillary cable,

Caution: After the regulator is
turned off using the keyboard,
dangerous voltage can occur on the
terminals. Before starting any
assembly works, you must
disconnect the mains supply and
make sure that there is no
dangerous voltage on the terminals
and the leads.

Connection of the 230V~ mains
voltage to terminals 25-48 or to
transmission terminals G2, G3, B
and USB results in the regulator
damage and poses a threat of
electrocution.

Unconditionally check if any lead of
the insulated cable, or the cable
itself DO NOT have electrical
connection with the metal
grounding strip (which is placed
near to high voltage terminals of
the regulator).

which was being correctly taken out from the
clamp box.

Connection cables should not have contact
with surfaces which temperature exceeds
cables nominal operating temperature.
Terminals 1-22 are designed to connect
devices supplied by the mains 230V~
voltage. Terminals 25–48 are designed to
work with low-voltage devices (<12V).

Tips of connection cables, especially mains
voltage cables should be secured from
splitting by e. g. insulated clamp sleeves in
accordance with the picture below: a –
properly secured, b – improperly secured.

12.4 IP protection rate

The regulator casing provides the IP20
protection rating. The casing on the
connectors cover side provides IP00 rating,
and because of that connectors must be
unconditionally covered with the cover.
If there is a need to gain an access to the
terminals side, it is a must to disconnect the
mains voltage and make sure there is no
dangerous voltage on regulator terminals.

12.5 Electric connection

The regulator is designed to be fed with
230V~, 50Hz voltage. The electrical system
should be:

 three core (with protective wire PE),
 in accordance with applicable regulations.

The feeder cable should be connected to the
terminals marked with an arrow.

22

All peripherals (such like: pumps,
RE-marked relays and connected
recipients) may be connected only
by qualified person in accordance
with applicable regulations. Safety
precautions to prevent electrocution
shall be observed.
Regulator shall be equipped with a
set of pins connected to 230V AC
mains.

to which they are connected.

sensors

The regulator is compatible only with CT4
and CT2S sensors. The use of other sensors
is prohibited!.
Wires of sensors can be extended by wires
with diameter no smaller than 0,5mm2. Total
length of wires in each sensor should not
exceed 15m.
The boiler temperature sensor should be
installed in a thermostatic pipe installed in
the boiler. Temperature sensor of hot water
silo should be installed in a thermostatic pipe
welded into the silo. The mixer temperature
sensor should be installed in a sleeve located
in stream of running water in pipe, but also it
can be installed on the pipe, on condition
that it is thermally isolated from the pipe.

12.7 Connecting weather sensor

he regulator cooperates solely with the
weather sensor type CT6-P. The sensor
should be installed on the coolest wall of the
building. Usually it is the northern wall,
under the roof. The sensor should not be
exposed to direct sunrays and rain. The
sensor should be installed at least 2 m above
the ground, far away from windows,
chimneys and other sources of heat.
To make the connection use wire with
diameter at least 0,5mm2 up to 25m long.
Polarization of wires is not essential. Second
end should be connected to terminals of the
regulator or properly to the used kind of
regulator.
The sensor should be screw to the wall.
Access to assembly holes is possible after
unscrewing the cover of the sensor.

Mounting temperature sensor: 1 - pipe, 2 –
clamps, 3 - thermal insulation, 4 - temperature
sensor.

Good thermal contact should be maintained
between sensors and the measured surface.
To this purpose thermal grease should be
used. It is not acceptable to lubricate sensors
with water or oil. Wires of sensors should be
separated from network electrical wires. In
such a case wrong readings of temperature
may be shown. Minimum length between
those wires should be 10 cm. It is not
acceptable to allow for contact between wires
of sensors and hot parts of the boiler and the
heating installation. Wires of sensors are
resistant to temperature not exceeding
100°C.

12.8 Connecting exhaust sensor

The exhaust sensor should be fitted in the
boiler flue. The gap between the sensor and
the flue should be sealed. The sensor should
be installed by a qualified fitter, while
observing regulations applicable for chimney
systems. The emission sensor should be
connected to the sensor terminals acc. to
The emission sensor lead cannot touch hot
elements of the boiler and the flue, the

temperature of which exceeds 350°C. The

emission sensor should be installed in such
distance from the boiler at which it is not
directly exposed to flames, and where the
emission temperature does not exceed
450°C.

26

Caution: Opening the boiler door
can cause the emission
temperature to exceed the

sensor‘s thermal resistance,

which can burn the sensor out.

12.9 Checking temperature sensors

Temperature sensors CT4/CT6-P/CT2S can
be checked by measuring their resistance at
the given temperature. In the case of finding
significant differences between the value of
measured resistance and the values
presented in the table below, the sensor
must be changed.

12.10 Connection of mixers room

thermostat

Room thermostat connected to the
operational unit affects mixer 1 circuit and/or
boiler circuit. If the whole heating circuit of
the building is supplied by a mixer with
electric servo, room thermostat for boiler
should be turned off.
Room thermostat, after disconnection of its
connectors reduces preset temperature of
the mixer circuit by a value set up in: Reduce
preset mixer temp. to thermostat. This
parameter is available in:
Mixer 1-4 settings
The mixer pump does not stop upon opening
contacts of the room thermostat unless other
settings have been made in the Service
Menu. Select the value of this parameter so
that once the room thermostat has
responded (its contacts have opened), the
temperature in the room drops.

27

12.11 Connection of boiler's room

Note: the boiler room thermostat
should be switched off if the whole
central heating system of the
building is supplied through a mixing
valve equipped with electric servo.

Once the preset room temperature
has been reached, thermostat opens
its contacts and the display shows:

.

The pump interlock by opening
the contacts of the room
thermostat may be activated only
upon making sure the boiler will
not be overheated.

It should to perform assembly and
installation of the module by
yourself, in conformity with the
applicable standards.

thermostat

The regulator may work with mechanical or
electronic room thermostat, which opens the
contacts once the preset temperature has
been achieved.
Set-up the operation of room thermostat in:

Boiler settings  Room thermostat 

Thermostat selection  Universal

Once the temperature in the room, in which
the room thermostat is installed, has reached
the preset value, regulator reduces the
preset boiler temperature by the value set in
Inc. p. b. temp. thermostat and the display

shows . This will cause longer breaks in
boiler operation (the boiler will remain in
SUPERVISION mode) and the same,
temperature in heated rooms will drop.
Moreover, the boiler pump (CH pump) may
be interlocked for a certain time by opening
the contacts of the room thermostat in
heated rooms. To activate this function ­enter:

Boiler settings → Room thermostat →
CH pump standstill

and set the value of this parameter >0.

Setting the value of e.g. ,,5” causes the

pump will be stopped by the room

thermostat for 5 min. When ,,0” is set, the

CH pump will not be stopped by the room
thermostat. Once this time has elapsed, the
regulator switches on CH pump for a time set
in CH pump op t. th. on e.g. 30s. This
feature prevents from excessive cooling of
the system caused by a pump stop.

12.12 Connection of reserve boiler

The regulator can control a reserve boiler
(gas- or oil-), eliminating the necessity of
enabling or disabling this boiler manually.
The reserve boiler will be enabled if the
temperature of the pellet boiler drops, and
disabled when the pellet boiler reaches an
appropriate temperature. Connection to a
reserve boiler, e.g. oil-boiler one, should only
be made by a qualified fitter, in accordance
with the technical documentation of this
boiler.
The reserve boiler should be connected via
relay to terminals 43-44 (Output H).

boiler to the regulator, where: 1- regulator, 2 –
reserve boiler (gas- or oil-), 3 – module U3,
consisting of relay RM 84-2012-35-1012 and base

In a standard version, the regulator is not
equipped with the U3 module.

Set the temperatures of reserve boiler switch
on/off:

Service settings  Boiler settings 
Reserve boiler  Reserve boiler
Reserve boiler activation temp.

Control of reserve boiler is off upon setting
this parameter at ,,0”.
Then should set the support for output H for
reserve boiler:

Service settings  Output H = Reserve
boiler

Once the boiler has been fired up, and its
temperature has exceeded the preset value
(e.g. 25C), regulator switches off the
reserve boiler and applies voltage 12V DC at
output H, which causes release of coil of U3
module relay and opening its contacts. Once
the boiler temperature has dropped below

signaling

The regulator may announce an alarm
condition by activating external device (e.g.
bell or GSM device to send SMS). Alarm
signaling and reserve boiler control use the
same terminals, therefore, setting of the H
output for alarm signaling deactivates the
function of reserve boiler control. Connect
alarm annunciator through U3 module.

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
from the boiler at any time it is
required by opening it completely.

Safety temperature limiter should
have nominal operation voltage of
~230V and should follow current
regulations.

Warning: 1-2 terminals are under
dangerous voltage.

RELPOL and base GZT80 RELPOL.

12.14 Connection of mixer

The regulator works only with mixing valve
servos equipped with limit switches. Use of
other servos is not allowed. The servos of full
turn time from 30 to 255 s may be used.
Description of mixer connection:

- connect mixer temperature sensor, ­connect mixer pump wiring,

- switch on the regulator and select proper
Mixer support in the service menu
Service settings  Mixer 1 Settings

- enter the proper Valve opening time in (this
time should be indicated on servo rating
plate e.g. 120 s).

- connect power supply to the regulator and
switch on the regulator to start the mixer
pump,

- determine direction of servo closing/
opening. For this purpose, set the selector
located on the housing of the servo to
manual control and find the positions in
which the temperature in mixer circuit is
maximum and minimum (it corresponds to
the setting of the regulator of "100% ON"
and "0% OFF, respectively). Note the
position to verify the connections later,

- disconnect power supply to the regulator,

- connect mixer servo and regulator wiring
according to valve servo manufacturer's
technical documentation. Do not mistake
direction of valve opening with its closing,

- connect regulator power supply,

- check whether wires to mixer closing and
opening are not interchanged. To do this,
enter MENU Manual control and open the
mixer by selecting Mix1 Open = ON. When

opening the servo, the temperature on mixer
sensor should increase. If not, disconnect
regulator power supply and switch the wires.
Note: Other reason may be incorrect
mechanical connection of the valve! – refer
to the documentation of valve manufacturer
and check whether the valve is properly
connected.

12.15 Connecting temperature

limiter STB

When temperature of water in the boiler

exceeds 95°C, power supply of the electric

feeder and the fan is cut off by the safety
temperature limiter. To reset the limiter it is
needed to press the button placed in the side
of the casing, near the power switch.
Pressing of that button is only possible when
temperature of water in the boiler drops.
If the regulator is not factory-equipped with
the safety temperature limiter, the STB
should be connected as an external device.
The STB temperature limiter should be
connected to the 1-2 terminals shown on the
electric scheme. If the safety temperature of
water in the boiler exceeds, the power supply
of the fan and the engine of feeder will be
cut off by the temperature limiter.

12.16 DS input

There is a possibility of connecting the sensor
that detects a door or fuel tank flap opening.
Opening of the DS contact results in
disconnection of the fan and the feeder
power supply. DS connector is under safe
voltage.

12.17 Connecting room panel

The regulator can be equipped with room
panel ecoSTER TOUCH, which can serve as:

- room thermostat,

- boiler control panel,

- alarm signalling device,

- fuel level indicator.

30

Cross-section area of wires used to
connect ecoSTER TOUCH control
panel should be 0,5mm2.

Max. length of wires should not exceed 30 m.

Software update can be
performed only by a qualified
person. Precautions to prevent
electrocution should be observed!.

ecoMAX860P

TOUCH

ecoSTER TOUCH

This length may be longer if the wires used
have cross-section area larger than 0,5mm2.

 Four-wire connection
Connection – see Electric scheme.

 Two-wire connection
For two-wire connection, power supply of
12V DC and rated current of min. 200mA is
required. Disconnect GND and +12V wires
from the module (2) and re-connect them to
external power supply unit arranged near
ecoSTER200 or ecoSTER TOUCH. The power
supply unit is not included in the regulator
supply. The max. length of wires to the
ecoSTER200 or ecoSTER TOUCH control
panel depends on cross-section area of a
wire, and e.g. for a wire of cross-section of

0.5 mm2 it should not exceed 30m. The
cross-section area of the wire should not be
less than 0.5 mm2.

To update the software:

 disconnect power supply of the regulator.
 insert microSDHC memory card (other

types of memory cards are not
supported) to a socket in the movable
casing of the panel shown above. On the
memory card there should be written new
software in the *.pfc format as a 2 files:
a file with the panel software and a file
with the module A software.

 Software files should be placed directly

on the memory card, do not place them
in any subdirectory,

 then connect power supply of the

regulator and go to:
General settings → Software update and
perform the update firstly in the A module,
then in the panel, and in the end in other
devices.

12.18 Software update

Simultaneous update of the regulator and
panel software can be done using memory
card only type microSDHC.

14 SERVICE 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.

 Ignition end 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.

 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.

14.1 BURNER

34

 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.

Exhaust temperature when no
fuel

If exhaust temperature is lower than this value for a time longer than the
time set in the Fuel lack detection time parameter, lack of fuel will be
detected and next firing-up attempt will be made.

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.

Exhaust temperature - blow
reduction

Exhaust temperature over which revolutions of the fan are reduced
(down to a minimum power).

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.

Feeder 2 operation time

Additional (external) feeder operation time.

14.2 BOILER

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.

 Lack of fuel detection time

Time is counted after fumes temperature drops below the Fuel detection
threshold value. In the grate mode, blow operation is stopped. If the
burner is active, flame test is started. Lack of fuel detection is off for "0"
setting.

 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.

 Boiler hysteresis

If boiler temperature goes below preset temperature by value of boiler
hysteresis, then automatic firing-up of burner takes place.

 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

35

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.

 Temperature shunt pump

activation

The temperature at which the shut pump is activated.

Thermostat select

The following options are available:
Off (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)

Min. boiler temp.

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 temp.

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.

Reserve boiler

Determines pellet boiler temperature below which reserve boiler is

activated (i.e. gas boiler). Setting "0” value causes deactivation of

reserve boiler control and switching joint number 43-44 on alarms
service.

Alarms

Allows for definition of alarm number or group of alarms after which exit
number 46-47 is connected. In order for alarms to connect exit,
parameter RESERVE BOILER must be set for value "0”.

Boiler cooling temp.

Preventive boiler cooling 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 support = floor On.

Parameter A,B,C FL

Parameter is related with automatic power modulation of boiler by
stabilizing the preset boiler temperature. The bigger the value the bigger
increase in power of the boiler. Too big value can cause instability of
sustaining the preset boiler temperature.

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.

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.

14.3 CH and HUW

36

Max. HUW temperature

It requires a HUW sensor to be plugged in. This parameter decides on
which maximum temperature will the HUW container 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.

Increase boiler temp. 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 extension 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 operation time

CH pump working mode

Available options: OFF = no support boiler pump; ON = boiler pump
works normally; shunt pump = boiler pump works as shunt pump; heat
exchanger = boiler pump works continuously in a short circuit boiler ­exchanger.

CH pump standstill time by
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 Off by thermostat = YES

CH pump activation time by
thermostat

Circulation pump starting
temperature

The temperature at which the circulation pump is activated.

14.4 BUFFER

Buffer support

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
stop temperature.

Loading stop temperature

Heat start installation

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.

Mixer support

 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.

14.5 MIXER

37

 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:
Off: (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.)

Min. 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.

Max. 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.

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
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].

Integration time constant

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].

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.

Pump Off by 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 input dead zone

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 input dead zone.

15 ALARM DESCRIPTION

Note: arrangement of
temperature sensor outside the
boiler water jacket (e.g. at the
outlet pipe) is not recommended
because boiler overheating may
be detected with delay.

The function of protection against
flame recession is inoperative if the
feeder sensor is disconnected or

damaged. The function of
protection against flame recession
is inoperative if the regulator is not
powered.

Regulator cannot be used as the
only protection against flame
recession in a boiler. Use
additional protective automatics.

Checking temperature sensors
described in this manual, in
point.12.8.

Checking temperature sensors
described in this manual, in
point.12.8.

15.1 Max. boiler temp. excess

Protection against boiler overheating
comprises two stages. In first instance i.e.
once the Boiler cooling temp. has been
exceeded, the regulator attempts to reduce
the boiler temperature by activation of the
boiler pump, HUW pump and opening the
mixer servo (only in case mixer circuit = CH
ON). Has the temperature dropped - the
regulator returns to normal operation. Is the
temperature still increasing (and has reached
95C), power supply to the fuel feeder and
the fan is off and permanent boiler
overheating alarm with sound signal is
produced. If, during boiler overheating time,
temperature measured by HUW sensor is
higher than Max. HUW temp., HUW pump
goes off. In this manner, users of hot utility
water are protected from burning. The alarm
is reset by switching the regulator off and on.
The alarm can be reset by restarting the
power supply.

15.2 Exceeding max. feeder

temperature

This alarm will occur after the feeder
temperature exceeds the parameter Max.
feeder temp. If the feeder temperature
exceeds this value, the regulator will enable
the feeder for a constant, programmed time
and will activate the poker. The airflow is
disabled and the pumps are enabled. After

„pushing the fuel out”, the regulator disables

the feeder and does not activate it again,
even if the feeder temperature is still high.
This alarm can be cancelled only after the
feeder temperature decreases, by restarting
the regulator.

15.3 Faulty fuel feeding system

This alarm occurs when an electronic control
circuit of the feeder is damaged. In that case
the feeder become controlled by an
electromechanical relay and because of that
feature boiler operation will not stop – which
is especially important during heating
season. The regulator then works in the safe
mode, which is indicated by a prompt

„Feeder control system failure” on the

screen.
In the event of an alarm, stop the

operation of the boiler and repair
immediately regulator.

15.4 Boiler temp. sensor damaged

This alarm occurs in case of boiler
temperature sensor damage and excess of
its measurement range. Upon occurrence of
this alarm, boiler, HUW and mixer pumps
start to possibly cool down the boiler. To
reset the alarm - switch OFF and ON the
regulator. Check the sensor and replace it, if
necessary.

15.5 Feeder temp. sensor damaged

This alarm occurs in case of damage of fuel
feeder temperature sensor and excess of its
measurement range. To reset the alarm ­switch OFF and ON the regulator. Check the
sensor and replace, if necessary.

15.6 Exhaust sensor temp. damaged

This alarm occurs in case of damage of
exhaust temperature sensor and excess of its

40

measurement range. To reset the alarm -

Checking temperature sensors
described in this manual, in
point.12.8.

Attention! Before work
continuation it is required to
check, if in the combustion
chamber there was a large
accumulation of unburned fuel. If
it is the case, than it is required
to remove this excessive fuel.
Firing the boiler with an fuel
overdose can lead to an
explosion of combustible gases!.

switch OFF and ON the regulator. Check the
sensor and replace, if necessary.

15.7 Unsuccessful firing up attempt

This alarm occurs after the third unsuccessful
automatic furnace firing up attempt. The
reason behind this alarm occurrence can be
among other things: malfunctioning igniter
or ventilator, malfunction of fuel feeder
system, incorrect parameter setting,
insufficient fuel quality or lack of fuel in the
container.
The alarm can be reset by restarting the
power supply.

15.10 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.
The alarm can be reset by restarting the
power supply.

15.11 No 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 “CAUTION!!!

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.

15.8 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
unburnt fuel. Check the quality and moisture
of the fuel.
The alarm can be reset by restarting the
power supply.

15.9 Boiler overheating STB, open

contact

This alarm occurs after activation of
independent safety thermostat that secures
the boiler against overheating. The burner
will then be deactivated. After the boiler
temperature will drop down it is required to
unscrew an oval STB lid and then press the
Reset button.

15.12 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.

15.13 No power supply

This alarm occurs after power to the
regulator, in the case of early no power
supply. The regulator returns to the mode of
operation where worked before the power
failure.

15.14 Fan or fan speed sensor

damaged

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

the only anti-freezing protective
measure! Apply other methods
too. Regulator manufacturer is

related damages.

off the fan.

17 REPLACEMENT OF PARTS AND

COMPONENTS

16 ADDITIONAL FUNCTIONS

16.1 Power supply decay

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

16.2 Anti-freezing protection

If the boiler temperature drops below 5C,
the CH pump will be enabled, thus forcing
circulation of the boiler water. This will delay
the process of water freezing, yet in the case
of great frost or shortage of power, it will not
protect the system against freezing.

16.3 Function of protecting pumps

against stagnation

The regulator performs the function of boiler,
HUW and mixer pumps and servo protection
from locking caused by scale deposit. To do
this, these components are periodically
(every 167h) switched on for few seconds. In
this way the pumps are protected from
immobilization caused by scale deposits.
Therefore, during boiler shut-down, power
supply to the regulator should be on, and the
regulator should be in STANSTILL mode.

16.4 Feeder bunker

After connect an additional module B
controller can be used with the sensor low
fuel level in the tank (the fuel supply from
the bunker). Upon activation of the sensor
(opening) at the Additional feeder operation
time controller activates additional feeder in
order to supplement the base fuel tank. This
parameter can be found in:

Service settings → Burner settings

If the parameter Additional feeder operation
time is set to “0” this work additional feeder

is turns off.

17.1 Replacement of mains fuse

Mains fuse is located in the Operating Unit. It
protects the regulator and other equipment.
In case of replacement, use 6.3A.
In order to take out the fuse, raise the fuse
holder using flat-blade screwdriver and take
out the fuse.

17.2 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

17.3 Lambda sensor

Burner efficiency can be increased by
connecting additional Lambda sensor
module. Connect the module according to
electric scheme. Lambda sensor is to be
activated in:

Service settings → Burner settings →
Lambda sensor

If parameter Operation with Lambda sensor
is set on ON then the controller will operate
using Lambda sensor readings. The amount
of air provided to the furnace will be
automatically set in such a way to obtain
preset amount of air in fumes. If this
parameter is set on OFF then Lambda sensor
readings will not have influence on
controller’s operation. Amounts of air for
given burner power are set in:

Boiler settings → Output modulation

Periodical calibration of Lambda sensor
readings can be necessary. To conduct
Lambda sensor calibration it is necessary to
extinguish the boiler. To make a successful
calibration the furnace in boiler must be
completely extinguished. To start up the
calibration use the parameter:

Boiler settings → Lambda calibration

Calibration process lasts approximately 8
minutes.
