ELECTRIC DEVICE UNDER VOLTAGE!

Before any action related to the power supply (cables
connection, device installation etc.) check if the regulator is not
connected to the mains!

Installation should be done by a person with appropriate
electrical qualifications. Improper cables connection could
result in the regulator damage.

The regulator cannot be used in steam condensation
conditions and cannot be exposed to water.

PRINCIPLES INDIVIDUAL FUZZY LOGIC:

 The regulator must be programmed individually for the given

type of boiler and fuel!

 It is inadmissible to change the type of gear-motor, fan, and

to make other changes in the boiler fittings which can
influence the burning process. The fittings should correspond
to the components installed by the manufacturer!

 It is recommended to operate boiler with maximally-opened

fan flap.

 Activation of the fuzzy logic mode does not eliminate the

necessity of regulating the SUPERVISION parameters.

 In some cases, the fuzzy logic mode may require additional

adjustment.

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.

 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 regulator is intended for boiler

manufacturers. Before applying the
regulator, a boiler manufacturer should

check if the regulator’s mating with the

given boiler type is proper, and whether
it can cause danger.

 The regulator is not an intrinsically safe

device, which means that in the case of
malfunction it can be the source of a
spark or high temperature, which in the
presence of flammable dusts or liquids
can cause fire or explosion. Thus, the
regulator should be separated from
flammable dusts and gases, e.g. by
means of an appropriate body.

 The regulator must be installed by a

boiler manufacturer in accordance with
the applicable safety standards.

 The programmed parameters should only

be altered by a person familiarized with
this manual.

 The device should only be used in heating

systems in accordance with the
applicable regulations.

 The electric system in which the regulator

operates must be protected by means of
a fuse, selected appropriately to the
applied loads.

 The regulator cannot be used if its casing

is damaged.

 In no circumstances can the design of the

regulator be modified.

 In the regulator there is applied

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

 Keep the regulator out of reach of

children.

2. General information

Boiler regulator ecoMAX860P 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 ecoSTER200 and ecoSTER TOUCH
situated in living quarters and module for the
web WiFi ecoNET300.
It can be used in a household and similar
facilities, as well as in lightly industrialized
facilities.

3. Information about documentation

The regulator manual is a supplement for the
boiler manual. In particular, except for this
manual, the boiler manual should also be
observed. The regulator manual is divided into
two parts: for user and fitter. Yet, both parts
contain important information, significant for
safety issues, hence the user should read both
parts of the manual.

We are not responsible for any damages caused
by failure to observe these instructions.

4. Storage of documentation

This assembly and operation manual, as well as
any other applicable documentation, should be
stored diligently, so that it was available at any
time. In the case of removal or sale of the
device, the attached documentation should be
handed over to the new user / owner.

5. Applied symbols

In this manual the following graphic symbols are
used:

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 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 speed 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
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).

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.

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

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.

Parameters should be so selected
that the boiler temperature in this

Power levels

11

mode gradually drops. Incorrect
settings may lead to boiler
overheating.

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.

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.

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 Settings HUW preset temperature

The device controls temperature of the
domestic how water - HUW container,
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:
HUW settings → HUW pump mode allows
the user to:
 disable filling of the HUW container,

parameter Off,

 set HUW priority, using the Priority

parameter - in this case, the CH pump is

deactivated to speed up filling of the HUW
container.

 set simultaneous operation of the CH and

HUW pump, using parameter No priority.

8.11 Disinfection of the 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 function is activated in the menu:

HUW settings → HUW disinfection

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

The regulator increases the HUW container
temperature once a week, at 2:00 a.m.
Monday. After 10 minutes of maintaining the
temperature at 70°C, the HUW pump is
switched off and the boiler returns to normal
operation. Do not activate the disinfection
function when the HUW support is off.

8.12 Setting HUW preset temperaturę

Preset HUW temperature is defined by
parameter:

HUW settings → HUW preset temp.

HUW container hysteresis
When the temperature drops below the HUW
set temperature – HUW container hysteresis,
the HUW pump will start in order to supply the
HUW container.

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

8.13 HUW circulation pump

The settings are located in:

HUW settings → Circulation pump night
time decrease

and

Service settings→ CH and HUW settings

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 operation time
between every Circulation pump standstill
time.

8.14 Enabling the SUMMER function

12

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

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

If the weather sensor is connected, switching
between SUMMER and WINTER mode may
occur automatically.

8.15 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
ecoSTER200/ecoSTER TOUCH. Upon
activation of the thermostat, the preset mixer
circuit temperature will be decreased, which,
if proper decrease value is selected, will stop
growth of temperature in the heated room.

Settings for mixer with weather sensor
without room thermostat
ecoSTER200/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.

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 ecoSTER200/ecoSTER
TOUCH.
Set parameter Weather contr.mixer to on.
Select weather curve. The
ecoSTER200/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. 8.16
it may be necessary to fine-tune the heating
curve translation.
In this setup, the ecoSTER200/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. 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,

13

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!.

8.16 Weather control

Depending on the temperature measured
outside the building, both preset boiler
temperature and temperatures of mixer
circuits can be controlled automatically. If
proper heating curve is selected, the
temperature of the circuits is calculated
automatically, depending on the outdoor
temperature. Thus, if the selected heating
curve is appropriate for the given building, the
room temperature stays more or less the
same, regardless of the temperature outside.
Note: during trial and error selection of
appropriate heating curve, it is necessary to
exclude influence of the room thermostat on
regulator operation (regardless of whether the
room thermostat is connected or not), by
setting the parameter:
Mixer 1 settings → Room therm. = Off
If a room panel ecoSTER200/ecoSTER TOUCH
is connected, it is also necessary to set the
parameter Room temp. factor to “0”.
Guidelines for proper setting of the heating
curve:

- floor heating 0,2 -0,6

- radiator heating 1,0 - 1,6

- boiler 1,8 - 4

Guidelines for selection of appropriate heating
curve:

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

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

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

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

8.17 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.
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.

14

Night time decrease may be set for working
days, Saturdays and Sundays.
The example of night time decrease of preset
temperature from 22:00 to 06:00 next day
and from 09:00 to 15:00 is given below.

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

In the given example, the regulator will set
the decrease of preset temperature by 3°C
from 00:00 to 06:00, and will keep the preset
value (without the decrease) from 06:00 to
09:00. Then, it will set the decrease by 5°C
from 09:00 to 15:00, and will keep the preset
value (without the decrease) again from
15:00 to 22:00; and again will set the
decrease by 3°C from 22:00 to 23:59.

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

Decrease of preset boiler
temperature in selected time
intervals is indicated by the symbol:

on the main screen

8.18 Grate

The regulator is able to work with a Grate,
where the fuel is loaded manually. The feeder
is switched off, but the fan is operational. You
can switch between Burner and Grate modes
in:

Boiler settings → Heat source

Fan speeds are regulated in:

Boiler settings → Output modulation

Fan speed settings are different for the grate
than for the burner. Other parameters are set
in the service settings.

Changing modes between grate and
burner can be done via the ecoNET
internet module, but only after all
the manually loaded fuel is burned
off. In order to change modes, turn

the regulator off and on by clicking

“Work mode” in the “Current
information” tab.

8.19 Manual control

Regulator offers possibility to manual start of
working equipment such as pump, feeder
motor or fan. This feature enables checking
whether the given equipment is fault-free and
properly connected.

Note: Access to manual control
menu is possible only 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.

8.20 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%
Tip: the fuel level can be viewed in the room
panel ecoSTER200 and ecoSTER TOUCH.

Operation of fuel level indicator.
Each time when fuel silo is filled to required
level it is necessary to press and keep the
knob in main window. Following info will
appear:

Once YES has been selected and confirmed,
fuel level is set at 100%. 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%
and confirm achieved 100% level by keeping
the knob pressed for a while!.

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

Set fuel level at
100%?

YES NO

15

calibration. No additional fuel level sensors
are required.

Calibration.
To perform calibration - fill the fuel tank to the
level corresponding to its full load and set the
parameter:

Boiler settings → Fuel Level → Fuel level
calibration → Fuel Level 100%

The indicator in the main window will be set
to 100%. On-going calibration process is
signalled by flashing fuel level gauge. The
gauge will flash until the time of marking the
point corresponding to minimal fuel level. One
must systematically control the decreasing
level of fuel in the bin. When the level reaches
the requested minimum, set the value of the
parameter:

Boiler settings → Fuel Level → Fuel level
calibration → Fuel Level 0%

Calibration process can be skipped if done
properly will set the parameters Feeder
efficiency and Tank capacity, which can be
found in:

Service Settings → Boiler settings.

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

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 stand­alone 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.

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 free-standing
device.

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

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

22

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,
which was being correctly taken out from the clamp
box.

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.

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 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).

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.

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.

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).

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

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.

Protection lead of the power supply cable and
protection leads of connected devices should
be connected to the grounding strip placed

Insulated clamp sleeve, 6mm lenght.

23

inside the casing of the regulator marked with

.
Before making any connections remove the
cover from the casing of the regulator as
shown below.

 cables secured from splitting should be

connected to screw terminals of the (6)
connector.

 cables should be put through cable outlets

in the casing (1) and secured from ripping
or loosening by a holdfast (5 – break it out
from the casing).

 cables insulation should be stripped by the

minimum possible, max. 60mm. If there is
a necessity to strip cable insulation more
than 60mm, cable leads should be fasten
together or with other leads near the
connector – in order to prevent contact
with unsafe parts in the case of falling out
the lead from the connector.

 it is not allowed to coil excess of the cable

and to leave not connected leads inside
the casing of the regulator.

1 – cable outlets, 2 – holdfasts placing (should be
broken out for the casing), 3 – improper cable
connection (it is not allowed to coil excess of the
cable inside the device and to leave cables with
stripped insulation), 4 – proper cable connection, 5
– holdfast of the cable, 6 – connector.

Electrical cables should be isolated
from hot parts of the boiler,
especially from flues.

 When the cables connection is done the

cover of the connectors has to be put in
place.

The connectors cover should be
always screwed on to the casing of
the regulator. Apart from providing
safety for the user, the connectors
cover also protects the interior of
the regulator from hazardous
environmental conditions providing
a proper level of the IP protection.

12.6 Temperature sensors connection

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.

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

Sensor must be protected from
getting loose from the surfaces to
which they are connected.

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.

12.7 Weather sensors connection

The 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.

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.

27

Connecting emission sensor: 1 – exhaust temp.
sensor type CT2S, 2 – sensor lead, 3 – flue.

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 boiler room

thermostat

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.

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

.

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

28

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.

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

12.11 Connection of mixer’s 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 1-5 settings  Room thermostat

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.

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.

Model diagram of layout for connecting a reserve
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
GZT80 RELPOL.

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

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

Set the temperatures of reserve boiler switch
on/off:

Service settings  Boiler settings 
Reserve boiler  Reserve boiler­deactivation 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  H output = 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 the value set
in the parameter of Reserve boiler
deactivation temperature, the regulator stops
to supply voltage to the output H, and the
reserve boiler switches on.

Entry of the regulator to “Boiler
switch off” conditions causes the
reserve boiler switches on.

12.13 Connection of alarm 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

12.14 Connection of mixer servo

When connecting electric servo of
the mixer take 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 the work so that
you may ensure heat collection
from the boiler at any time it is
required.

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 80 to 255 s may be used.
Description of mixer servo connection:

- connect mixer temperature sensor,

- switch on the regulator and select proper
Mixer support in service menu:

Service settings  Mixer settings 
Mixer support, e.g. CH ON.

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

- disconnect power supply of the regulator,

- determine direction of servo closing/
opening. For this purpose, set the selector
located on the housing of electric servo at
manual control and find the positions of the
valve 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). Write down these

positions.

- connect mixer pump,

- wire mixer servo with the regulator,

- connect power supply to the regulator,

- check whether wires to mixer closing and
opening are not interchanged. To do this,
enter menu: Manual Control and open the
mixer by selection of Mix1 open = ON. When
opening, temperature on mixer sensor should
increase. In other case, disconnect power
supply to the regulator and interchange the
wires (Note: other reason of this fault may be
incorrect mechanical connection of the valve!
– refer to the documentation of valve
manufacturer and check whether the valve is
properly connected),

- calibrate % factor of mixer valve opening.

To do this, disconnect power supply of the
regulator and set the selector on housing of
electric servo at manual control. Turn the
valve head to fully closed position, and set the
selector on the housing of electric servo at
AUTO again. Connect power supply to the
regulator. Now, % factor of mixer valve
opening has been calibrated. Note: Calibration
in mixers no. 2,3,4,5 starts automatically
upon connection of power supply. In case of
these mixers - wait until a % factor of the
mixer valve opening has been calibrated.
During the calibration, servo is closed for the
time set in Valve opening time. Running
calibration is indicated by "CAL" in the menu:
Information, tab "Mixer-Info",

- set other parameters of the mixer.

12.15 STB temperature limiter

Version with temperature limiter
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.

Version without temperature limiter
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.

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

Warning: 1-2 terminals are under
dangerous voltage.

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

31

disconnection of the fan and the feeder power
supply. DS connector is under safe voltage.

12.17 Connection of room control panel

The ecoSTER200/ecoSTER TOUCH room
control panel may be installed. Main functions
of the panel are following:

- room thermostat (3 thermostat units),

- boiler control,

- alarm annunciator,

- fuel level indication.

4-wire connection:
 The room panel ecoSTER TOUCH should be

connected to the G3 connector of the
regulator, according to the electric
scheme.

 The version 2 of the room panel

ecoSTER200 should be connected as
shown in the picture below, together with
room sensors CT7 of a thermostat 2,3.

2-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.

12.18 Software update

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

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

ecoMAX860P

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.

14. SERVICE SETTINGS

14.1 BURNER

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.

 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.

36

 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.

14.2 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 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.

37

 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 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.

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.

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 Off by 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)

14.3 CH and HUW

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.

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 operation time by
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 container be heated during

38

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

Heat 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)

14.4 BUFFER

Buffer settings

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.

14.5 MIXER

Mixer 1-5 settings

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

39

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:
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.

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
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 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

40

or higher than the set temperature by a value exceeding the Mixer input
dead zone.

15. ALARM DESCRIPTION

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 pressing the
encoder “TOUCH and PLAY” knob or restarting
the power supply.

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.

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 pressing
the encoder “TOUCH and PLAY” knob or by
restarting the regulator.

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.

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.

The alarm can be reset by pressing the
encoder “TOUCH and PLAY” knob or restarting
the power supply.
It is also possible to continue operation in
emergency mode. Before continuing
operation, 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!

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).

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.

Checking temperature sensors
described in this manual, in

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.

Checking temperature sensors
described in this manual, in
point.12.9.

15.6 Exhaust sensor temp. damaged

This alarm occurs in case of damage of
exhaust 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.

Checking temperature sensors
described in this manual, in
point.12.9.

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 pressing the
encoder “TOUCH and PLAY” knob or restarting
the power supply.

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!.

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 pressing the
encoder “TOUCH and PLAY” knob or 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.

15.10 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 pressing the
encoder “TOUCH and PLAY” knob or 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.

15.12 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

43

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 off the fan.

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.

Note: This function must not be
the only anti-freezing protective
measure! Apply other methods
too. Regulator manufacturer is
not liable for anti-freezing related
damages.

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. REPLACEMENT OF PARTS AND

COMPONENTS

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.
