General information
The ecoMAX 200 series boiler regulator is an
electronic device intended for solid fuel
boilers. It performs the following functions:
•
Automatic stabilization of a given
temperature of the boiler cycle,
•
Automatic stabilization of a given
temperature of the hot utility water tank.
Combusting regulation is performed using
three selectable methods:
- by linear reduction of the airflow power
when the temperature approaches the preset
boiler temperature (CLASSIC regulation),
- by smooth modulation of the airflow power
(PID regulation without an emission sensor),
- by smooth regulation of the airflow power
(PID regulation with an emission sensor)1.
After equipping the regulator with an
additional emission sensor, it is possible to
quickly detect that the fuel is running out in
any mode of the boiler regulation. This
decreases heat losses related to the fan
operating without any fuel, and extends the
boiler‟s readiness for refuelling. The fuel
needs not be added quickly, as fast detection
of the lack of fuel maintains glow in the
boiler furnace for a longer time.
The fan start is smooth. This decreases the
risk of gas explosion in the boiler chamber,
which is of particular significance in fine coal
boilers.
The device is operated in an easy and
intuitive way.

First start-up of the regulator
Before the first start-up of the regulator, it
should be programmed for the purposes of
cooperation with the given boiler and heating
system, in accordance with point 11.9. It is
recommended that this performed by a
person familiar with heating technology.
7.3

Caution: The combustion regulation
methods
described
below
will
properly regulate the combustion
process, as long as the boiler is
operated
in
accordance
with
recommendations of the boiler
manufacturer. You should pay
special attention to the place of
setting fire during firing up!
The regulator is started by pushing the mains
switch (4) Drawing 1. First, an information
window with the software version appears,
then the regulator displays the main window.
7.4
Firing up – activation of airflow
In order to fire the boiler up, you should put
fire under the fuel, in accordance with the
boiler documentation, close the boiler door
and activate airflow by pushing the START
button. The fan will be activated. Pushing
STOP turns the fan and the regulation
process off.
7.5
Presetting boiler temperature
The boiler temperature can be preset by
pushing the F button in the main menu. A
signalling
arrow
next
to
the
sign
„Temperature setting” is lit, and the boiler
preset temperature value in the upper part of
the thermometer flashes. START and STOP
buttons are used to increase and decrease
the preset boiler temperature respectively.
7.6
Presetting hot utility water
temperature
If the hot utility water temperature
sensor is not connected, it is not
possible to preset the hot utility
water temperature.
The hot utility water temperature can be
preset by pushing the F button in the main
menu twice. A signalling arrow next to the
sign „Temperature setting” is lit, and the hot
utility water preset temperature value in the
upper part of the thermometer flashes.
START and STOP buttons are used to
increase and decrease the preset hot utility
water temperature respectively.

Combustion regulation methods
The regulator features

the combustion
CLASSIC regulation (regulation mode 1)
In order to enable the CLASSIC mode of
boiler regulations, set the boiler regulation
mode
to value 1. In order to do so, press
the F button in the main window until the
arrow is in the boiler regulation mode
position. Use „+” or „-" buttons to set value
Three modes of combustion control
are available: 1 - CLASSIC, 2 - PID,
3 – PID SALINES point 7.7.
The method is based on the T1 boiler
indication, and consists in decreasing of the
airflow power from Maximum revolutions
to Minimum revolutions
while achieving
the preset boiler temperature. Revolutions
start to be reduced at 5°C (service
parameter n7) before the preset boiler
temperature. After achieving the preset
boiler temperature, the SUPERVISION mode
is activated, where blow-offs are performed.
Before enabling this mode for the first time,
it is recommended to program the regulator
in accordance with point 11.9.
PID regulation (regulation mode 2)
After setting the parameter boiler regulation
mode = 2.
This method is based on boiler temperature
indications T1, it consists in constant,
smooth modulation of the fan revolutions in
order
to
stabilize
the
preset
boiler
temperature. The regulator itself selects the
airflow power in such a way that the boiler
generated
minimum
amount
of
heat
necessary to satisfy the heat demand of the
building. Transition to the SUPERVISION
mode is rare and it happens during lack of
heat demand.
Before enabling this mode for the first time,
it is recommended to program the regulator
in accordance with point 11.9.
PID EMISSION regulation (regulation
mode 3) – new!
9
After setting the parameter boiler regulation
mode = 3 (emission sensor must be
connected).
This method is based on emission sensor
indications T3. It consists in constant,
smooth modulation of the fan revolutions in
order to stabilize the preset emission
temperature. As opposed to the boiler
regulation mode = 2, the airflow operation is
more stable, without excessive increasing of
the airflow power, which makes that method
more economical in respect of fuel saving.
After loading the fuel and pushing the START
button, the fan operates with maximum
revolutions
. As the preset emission
temperature is approached, the revolutions
are automatically reduced. When the
emission temperature reaches the preset
temperature for the first time, a slight
adjustment is made.
In the PID EMISSION mode, it is possible to
temporarily increase the emission preset
temperature. This facilitates firing the boiler
up. Thanks to this, the temperature in the
heated rooms will increase faster, without
the necessity of going to the boiler room
later on, in order to decrease the boiler
Setting

temperatures
lower than at about 160°C can

power. To temporarily increase the boiler
power, for e.g. 30 min, enable the fan using
the START button, than push the START
button again and hold it for 2 s. The boiler
symbol at the display starts to flash Drawing

The
preset
emission
temperature
increases „covertly” to value = r7 (service
parameter, by default = 300°C). After time
r8 (service parameter), the preset emission
temperature returns to the set value.
Drawing 3. Temporary power increase in the PID
EMISSION mode
Moreover, after equipping the regulator with
an emission sensor, it is possible to enable
very fast detection of fuel shortage. This
provides additional saving of heat energy
resulting
from
almost
instantaneous
deactivation of the fan when the fuel runs
out. Also, the fuel needs not be added
quickly, as fast detection of the lack of fuel
maintains glow in the boiler furnace for a
longer time.
In order to preset the emission temperature,
press the “F” button until the following
window appears:
Drawing 4. Presetting emission temperature
Use the „+” and „-” buttons to respectively
increase or decrease the preset emission
temperature; please note that the value in
the upper part of the thermometer symbol,
e.g.: 20°C, means 200°C. Unless the boiler
manufacturer specified otherwise, the preset
emission temperature should generally be
between 160 and 300°C. Whereas in order to
achieve higher boiler power, it might be
necessary to set greater values (e.g. during
very frosty weather).
The optimal preset emission temperature
depends on the type of fuel and the boiler
design, and it should be determined
experimentally. When burning wood, the
flame should be blue-yellow, and when
burning coal – yellowish. For example, the
optimal temperature for wood is between
190 and 260°C.
10
If optimal emission temperature causes
excessive heating up of the boiler, it is best
to store the surplus energy in a thermal
buffer. If the central heating system does not
feature a thermal buffer, you such find such
preset emission temperature at which the
temperature of water in the boiler is at the
desired level. If it is too hot in a room,
decrease the preset emission temperature,
and increase it in the opposite case. The
preset boiler temperature is in this method of
secondary importance, it prevents exceeding
undesirable temperature of the boiler. It is
recommended
to
preset
the
boiler
temperature as 10°C higher than the
expected boiler temperature after the
emission temperature settles. After the boiler
reaches
the
preset
temperature,
the
regulator switches to the SUPERVISION
mode.
High emission temperature, even if
the fan rotates slowly, can mean
that the boiler is contaminated – in
such case, it should be cleaned.
Before enabling this mode for the first time,
it is recommended to program the regulator
in accordance with point 11.9
Caution:
the
regulator
will
automatically
switch
from
regulation mode 3 to mode 1, if the
emission sensor is damaged or if
the emission temperature exceeds
the emission sensor measuring
capacity. Therefore, it is important
to set proper parameters for the
regulator to operate in mode 1,
without causing any danger.
7.8
SUPERVISION
The regulator switches to the SUPERVISION
mode in the following circumstances:
a) In the case of CLASSIC and PID
EMISSION modes of regulation – if the
boiler temperature exceeds the preset
boiler temperature,
b) In the case of PID mode of regulation – if
the boiler temperature exceeds the
preset boiler temperature by +10°C.
In the SUPERVISION mode the fan is enabled
cyclically for short periods, in order to
prevent the fire from going out and to
remove accumulated combustible gases from
the boiler furnace chamber. The fan is
enabled for blow-off time at every blow-off
interval. These times must be selected in
such a way that the boiler furnace did not go
out and, at the same time, to prevent the
boiler temperature from increasing.
Incorrect selection of blow-off
parameters
can
cause
boiler
overheating.
7.9
Settings for hot utility water
The device regulates the temperature of the
hot utility water tank, provided that a hot
utility
water
temperature
sensor
is
connected. Using the hot utility water mode
parameter
, the user can:
 set the hot utility water priority (HUW
mode =1) – the central heating pump
is disabled to fill the hot utility water
tank faster
 set simultaneous operation of central
heating and hot utility water pump
(HUW mode = 2),
 enable the SUMMER function (HUW
mode = 3),
 disable tank filling (HUW mode =4),
If the hot utility water sensor is
disconnected, the hot utility water
mode user parameter cannot be
changed.
7.10 Enabling the SUMMER function
In order to enable the SUMMER function,
which allows to fill the hot utility water tank
in the summer without the need of warming
the central heating system, set the
parameter hot utility water mode = 3.
Do not enable the SUMMER function if
the hot utility water pump is
disconnected.
The SUMMER function cannot be
enabled if the hot utility water sensor is
disconnected.
The SUMMER function can be enabled
only after making sure that the boiler will
not overheat. If the SUMMER function is
enabled, the heat consumption is much
lower, because the central heating pump
is inactive. The method of decreasing the
boiler overheating is described in point
11
12.15
Do not enable the SUMMER function
in a hydraulic system with a thermal
buffer
7.11 Operation without airflow
Unless the START button is pressed in the
main display window (right after turning the
regulator on via the mains switch), the
device controls only the pumps.
The central heating pump and the hot utility
water pump operate in accordance with their
algorithm. They are activated if appropriate
conditions are met. The conditions for pump
activation are described in individual sections
of the manual.
If the boiler is cold, the pumps do
not work. The pumps can start
working only after the boiler
exceeds the Central heating pump
activation temperature n0 [by
default 40°C]
In order to use the regulator without
active fan, press the STOP button in
the main display window.

temperature (service parameter n0, by
default n0 = 40°C). The hot utility water
pump
is
activated
when
the
tank
temperature (6) drops below the preset
value. If at this time the preset boiler
temperature is lower than the preset hot
utility water temperature, the regulator
increases the preset boiler temperature in
order to fill the hot utility water tank. After
filling the hot utility water tank, the hot
utility water pump can continue work for a
preset time, in order to collect heat from the
boiler. After the room thermostat (5)
operates, the regulator decreases the preset
boiler
temperature
and/or
temporarily
disables the central heating pump (2). Fitting
an emission temperature sensor (8) in the
boiler flue enables very fast detection of fuel

Brief description of the system functioning:
Due to the risk of explosion or fire, it is
prohibited to operate the regulator in
explosive
gas
and
flammable
dust
atmosphere (e.g. coal dust). In such cases, it
is necessary to apply additional measures
protecting the regulator against penetration
by flammable dusts and gases (tight body),
or to prevent their emergence.
On account of risk of shock, the regulator
has been designed to be used in an

display.
Drawing 10. Conditions of enclosing the regulator
The regulator enclosure must provide degree
of
protection
appropriate
for
the
environmental conditions in which the
regulator will be used. Moreover, it must
prevent the user from accessing dangerous
live parts, e.g. the terminals. The regulator
enclosure does not provide resistance to dust
and water. In order to secure the device
against these factors, the module must be
equipped with appropriate body.
Due to thermal conditions and safety issues,
a safe distance between active parts of the
terminals and the conductive (metal)
elements of the enclosure must be kept –
Drawing 10. Metal elements of the regulator
enclosure must be connected with the
protective wire of the feeding cable Drawing
12.
Connecting wires must be protected against
being torn out, loosened, or they must be
enclosed in a way which prevents any
tensions in relation to the wires.
11.3 IP protection rate
The regulator casing provides various rates
of IP protection in various places. Drawing 10
provides and explanation. After enclosing the
device, in accordance with the drawing from
the face of the regulator, it has protection
rate IP 40. From the side of the terminals,
the regulator has protection rate IP00,
therefore
the
terminals
must
be
unconditionally enclosed, thus preventing
access to this part of the regulator.
11.4 Connecting electrical system
He regulator is designed to be fed with
230V~, 50Hz voltage. The electrical system
should be:

Terminals 9-20 are intended for cooperation
with low voltage devices (below 12 V).
Connecting mains supply 230V~ to
terminals 9-10 will damage the
regulator and creates risk of an
electric shock.

11.10 Connecting room thermostat
To make the boiler more economical, and the
temperature in the heated rooms more
stable, install a room thermostat.
The
regulator
is
compatible
with
a
mechanical or electronic room thermostat,
which disconnects its contact after a preset
temperature
has
been
reached.
The
thermostat
should
be
connected
in
accordance with Drawing 12.
After installing a room thermostat, you must
enable its support. To do so, set the service
parameter
Room
thermostat
(service
parameter n8 = 1).
After
reaching
the
preset
temperature in the room, the room
thermostat disconnects its contacts,
and a symbol appears on the display
(symbol 7, Drawing 2)
When the temperature in the room in which
the room thermostat has been installed
reaches the preset value (the room
thermostat disconnects its contacts), then:
a) the ecoMAX 200 regulator lowers the
preset boiler temperature by the
value Boiler preset temperature
decrease by thermostat (service
parameter r0), which is signalled by
symbol 10, Drawing 2.
b) the ecoMAX 200 regulator will block
the central heating pump for 30 s at
intervals Central heating pump downtime
by
thermostat
(service
parameter n8). If n8 = 0, there is no
central heating pump blockade.
It is not recommended to block
the central heating pump if the
PID
mode
of
regulation
is
selected, in such case it suffices to
lower
the
boiler
preset
temperature. The regulator will
automatically
reduce
its
revolutions.
Central heating pump blockade by
thermostat can be enabled only
after making sure that the boiler
will not overheat.
19
11.11 Connecting
temperature
limiter
STB
In order to prevent the boiler from
overheating
due
to
the
regulator
malfunction, a safety temperature limiter,
appropriate for the given boiler and heating
system, should be fitted.
The limiter can be connected to terminals 12, as specified in Drawing 12 . When the
limiter activate, the fan power supply will be
disconnected.
The temperature limiter must
have nominal operating voltage of
at least ~230V, and it should have
the applicable permits.
The
additional
thermal
protection cannot be used
instead of the mandatory
safety temperature limiter!
11.13 Smooth fan start
During every activation of the fan, the
regulator gradually increases the airflow
power, which decreases the risk of explosion
of gases accumulated in the boiler. This
advantage is of particular significance in the
case of fine coal boilers.
The fan starts smoothly from Minimum
revolutions
to power resulting from the
algorithm within the P5 time (manufacturer‟s
parameter – fan starting time).
If the limiter is not connected to terminals 12, a bridge should be made. The bridge
should be made of wire the section of which
is at least 0,75 mm2, with insulation thick
enough to comply with the boiler safety
requirements.
The current regulations demand
that a safety temperature limiter
is used.
11.12 Connecting
additional
thermal
protection
The ecoMAX 200 regulator can be equipped
with additional thermal protection, type DZT1. This is an optional equipment, available to
special order. It cuts off the fan power
supply. Sensor of the additional thermal
protection, which operates on low safe
voltage,
should
be
placed
in
the
thermometric pipe of the water jacket. You
should provide good thermal contact of the
DZT-1 sensor, and secure it against coming
loose from the measured surface.
If the boiler temperature exceeds the DZT-1
sensor activation temperature (85°C or 90°C
±5 depending on the DZT-1 type), the fan
power supply is cut off. The fan power supply
will be automatically restored after the boiler
temperature drops by 10-20 degrees Celsius.
If a DZT-1 sensor is not connected, an
electric bridge should be made at terminals
11-12.

12.1 Central heating pump activation
temperature n0
The
(n0)
parameter
specifies
the
temperature at which the central heating
pump is activated. After reaching the
temperature equal to the Central heating
pump activation temperature parameter, the
central heating pump is activated. This
protects the boiler against retting caused by
its being cooled down by hot water returning
from the system.
Disabling the central heating pump
on its own does not guarantee
protecting the boiler against retting,
and resulting corrosion of the boiler.
Additional automatics should be
applied, e.g. four-way valve, or
thermostatic three-way valve.
12.2 Boiler hysteresis n1
The
(n1)
parameter
determined
the
temperature at which the boiler returns from
the SUPERVISION mode to the OPERATION
mode. The regulator returns to the
OPERATION mode at the temperature preset
boiler temperature – boiler hysteresis.
12.3 Minimum airflow power n2
When the regulator is turned on for the first
time, it is necessary to set the user-defined
parameter Minimum airflow power. After
setting a value of e.g. 14%, the user will be
able to set airflow power of at least 14%.
The minimum airflow power should be
determined
after
observing
the
fan
behaviour. You must determine minimum
value of revolutions at which the fan can
rotate properly, i.e. freely, without rattling.
Set boiler regulation mode = 1 Maximum
revolutions and Minimum revolutions to the
value of revolutions you want to test. For
most fans, this will be 12 – 15%.
12.4 Minimum boiler temperature n3
This parameter can be used to prevent the
user from setting too low preset boiler
temperature. If the boiler operates at too low
a temperature, it can cause its rapid
damage, corrosion, soiling, etc.
Set the value in accordance with the
boiler
manufacturer‟s
recommendations
12.5 Maximum boiler temperature n4
This parameter can be used to prevent the
user from setting too high preset boiler
temperature.
21
Set the value in accordance with the
boiler
manufacturer‟s
recommendations
12.6 Fuel shortage detection time n5
This is the time after which the regulator will
produce the fuel shortage alarm.
If the regulator produces the “No
fuel” alarm too fast, increase the
value of this parameter.
Recommended settings of the n5 parameter
depending on the method of detecting fuel
shortage:

1 – boiler sensor
2 – emission

Methods of detection are specified in point
12.21.
12.7 Screen brightness n6
Increases or decreases the brightness of
display backlight.
12.8 Fan revolutions’ reduction
temperature n7
This parameter is applicable only if the boiler
regulation mode
= 1 – CLASSIC is
enabled. After the boiler reaches the boiler
preset temperature – n7, the fan starts
reducing its revolutions until the boiler preset
temperature is reached. By default n7 = 5C.
temperature (point 11.10). As a result of
blocking the central heating pump, the
temperature in the heated rooms will drop,
and the boiler will reach the preset
temperature faster and switch to the
SUPERVISION mode. Yet, too long a
blockade of the central heating pump will
cause the system to cool down, which is
disadvantageous for maintaining the room
temperature at constant level. The heating
medium accumulated in the system has high
thermal inertia, and heating it after the
thermostat contacts are shorted can take too
long. Thus, it is not recommended to set
excessively long central heating pump downtimes. After the central heating pump downtime by thermostat (service parameter n8),
the regulator will enable it for a constant,
pre-programmed time of 30 s.
12.10 Fuel shortage detection methods
n9
This parameter determines the method of
detecting fuel shortage. If:
n9 = 1, fuel shortage is detected on the
basis of the boiler temperature readings T1,
point 14.1,
n9 = 2, fuel shortage is detected on the
basis of emission sensor T3 readings. Do not
set n9=2 if emission sensor is disconnected.
12.11 Lowering the preset boiler
temperature r0
Settings of lowering the preset boiler
temperature r0 are described in point 11.10.
12.12 Hot utility water tank hysteresis
r1
This is a drop of temperature below which
the hot utility water pump is restarted in
order to fill the hot utility water tank.
Drawing 14 Fan revolutions‟ reduction with classic

12.9 Central heating pump down-time
by thermostat n8
After setting a low value, the hot
utility water pump will start faster,
yet this is disadvantageous due to
frequent activation of the pump.
This parameter determines the central
heating pump down-time after it is blocked
by disconnected room thermostat, at the

12.13 Boiler preset temperature
increase r2
Boiler preset temperature increase by hot
utility water r2. This parameter specifies by
how many degrees the boiler preset
temperature will be increased in order to fill
the hot utility water tank. Yet, this action will
be performed only when such need arises.
When the boiler temperature is high enough,
the regulator will not change it for the
purposes of filling the hot utility water tank.
Increasing
the
boiler
preset
temperature for the time of filling
the hot utility water tank is signalled
by symbol no. 9 in the main display
window - Drawing 2
12.14 Maximum hot utility water
temperature r3
This parameter specifies the maximum
temperature of the hot utility water tank at
danger levels. The hot utility water tank is
used to drop excessive heat if the boiler
overheats. In order to protect the hot utility
water users against burns, the maximum
temperature of the hot utility water tank
should be limited.
Except for the software safeguard
against too high a temperature of
the hot utility water tank, additional
protective automatics should be
used, e.g. a mechanical
thermostat which disables the hot
utility water pump feeding.
12.15 Extending hot utility water pump
operation r4
After filling the hot utility water tank and
disabling the hot utility water pump, there is
often a problem of boiler overheating. It
occurs if the preset hot utility water
temperature is higher than the preset boiler
temperature. This problem is particularly
common in the SUMMER mode of the hot
utility water pump, when the central heating
pump is disabled. In order to cool the boiler
down, operation of the hot utility water pump
can be extended by the time r4 Extending
hot utility water pump operation.
12.16 Fuel shortage detection –
emission temperature r5
The value of the r5 parameter determines
the temperature of emission below which fuel
shortage detection will be made on the basis
of the T3 sensor readings. If the regulator
causes too high a consumption of fuel, which
makes the furnace go out completely, the r5
temperature should be increased. Act
analogically in the opposite case.

detection – see point 12.10

it
is
recommended to set r6=1.

example, 30 means temperature of 300°C.

This is the time for which the emission preset
temperature is increased to the r7 value,
after holding the START button for 2 seconds
when the regulation mode = 3 PID

12.20 Restoring service settings r9
In order to restore default settings, set the
value of service parameter r9 to “1” and
press the F button.
Default settings of user and service
parameters will be restored.
12.21 Methods of detecting fuel
shortage
23
Fast detection of fuel shortage decreases
losses of heat caused by the fan operating
with no fuel, and it allows to sustain fire for a
longer time, during which the boiler can be
refuelled without the need of firing it up
again.
1-first method – based on the boiler
temperature sensor readings T1 (factory
parameter
S9=1).
After
the
boiler
temperature drops below the n0 parameter
Pump activation time, the fuel shortage
detection time n5 is counted out (see point
12.6). If after that time the boiler
temperature does not rise, the AL1 alarm is
produced and the fan is disabled.
2-second method (recommended) – based
on emission temperature sensor readings
(factory parameter S9=2). This method
allows very fast detection of the fuel
shortage. It can be used only if an emission
sensor T3, placed in the boiler flue, is
connected. After the emission temperature
drops below the factory parameter P8 (Fuel
shortage detection – emission temperature),
the fuel shortage detection time n5 is
counted out (see point 12.6). If after this
time the temperature does not increase, AL1
alarm is produced.
The AL1 alarm will be cancelled after:
- pushing the START button, or after
- disabling and enabling the regulator via
mains switch.

After detecting fuel shortage, the following
message will appear on the display
24
cause stoppage of the boiler.
Before the boiler reaches the P0
temperature, the regulator will
attempt to drop the excessive heat
to the hot utility water tank. If the
hot utility water tank reaches the
maximum temperature permitted
by the r3 parameter, the hot utility
water pump is turned off, and the
AL3 alarm is produced.
Drawing 2 AL1 alarm
No sound signal will be given.
The way and methods of detecting fuel
shortage are described in point 12.21.
Note: placing the temperature
sensor beyond the boiler water
jacket, e.g. on the outlet pipe, is
not recommended, as it can delay
detection of the boiler overheating.
14.2 Boiler temperature sensor damage
AL2
This alarm will be produced in the case of
damage to the boiler sensor, and after
exceeding its measuring range. The alarm
sauces shut-down of the central heating and
hot utility water pumps, in order to cool the
boiler down, if applicable. A sound signal is
also activated.
The alarm is cancelled after returning to the
sensor measurement range, and after
disabling and enabling the regulator via the
mains switch.
In such case, check the sensor, and possibly
replace it.
The method of checking the
temperature sensor is described in
point 11.8
14.3 Exceeding the maximum boiler
temperature AL3
This alarm will occur after the boiler exceeds
temperature determined by the factory
parameter

alarm
temperature P0. By default, this parameter is
set to 90C. In such case, the fan is turned
off, and the central heating and hot utility
water pumps are activated. A sound signal is
also activated. The hot utility water pump
works only until the hot utility water tank
exceeds the maximum temperature r3
(service parameter). This protects the users
against possible scalding.
After the boiler temperature drops, the
regulator resumes normal operation.
It is suggested to set the P0 value
below the safety temperature
limiter actuation threshold. Thanks
to this, a momentary exceeding of
the boiler temperature will not
14.4 Exceeding maximum emission
temperature
The regulator warns the user of a danger of
emission temperature sensor damage if the
emission temperature exceeds 450°C. Such
situation can occur if the wrong regulator
parameters are set, or if the boiler door are
left open.
The alarm is signalled visually, by a warning
triangle symbol, and with a sound – short
warning signals.
15 Replacement of parts and
subassemblies
When ordering parts and subassemblies,
please specify necessary information read off
the rating plate. It is best to give the
regulator serial number. If the serial number
is not known, please specify the model and
type of the regulation, as well as the year of
its production.
15.1 Replacing mains fuse
The mains fuse can be found in the regulator
front panel. It protects the regulator and the
devices fed by it. Please use time-delay
fuses, porcelain, 5x20mm, of nominal
burnout current 3,15A, e.g. 02153.15P made
by LittelFuse.
In order to remove the fuse, push in its
socket with a flat-tip screwdriver and turn it
counter clockwise.

the
heaters are hot and the
boiler overheats
7. the hot utility water
pump is active even
after the hot utility
water tank has been
filled
8. the boiler overheats
despite enabled fan
Check:
 if the main fuse is burnt-out, replace if so,
Check:
 whether the hot utility water tank is filled at the time and the
preset hot utility water temperature is higher than the boiler
preset temperature; if so, the difference of readouts will
disappear after the hot utility water is filled, or after decreasing
the preset hot utility water temperature.
 whether the room thermostat is on – set the service parameter
Decreasing boiler preset temperature by thermostat r0 = 0
Check:
 whether the boiler exceeded the parameter Pump activation
temperature (n0) – wait or decrease this parameter,
 if the room thermostat is not blocking the central heating pump set the parameter central heating pump down-time (n8) to “0”.
 if the hot utility water priority, which blocks the central heating
pump, is enabled – disable the priority by setting the hot utility
water mode = 2 (Without priority),
 whether the central heating pump is not damaged or clogged.
 check the value of the parameter Minimum airflow power (n2)
 check if the safety temperature limiter STB input jumper is on
terminals 1-2 (the jumper should be placed only if no
temperature limiter is connected).
 check if the additional thermal protection sensor input jumper is
on terminals 11-12 (the jumper should be placed only if no DZT01 sensor is connected)
 if the boiler manufacturer equipped it with a temperature limiter
STB with manual return to the initial position, unlock it by
removing the lid and pushing the button, in accordance with the
documentation provided by the boiler manufacturer.
 check the fan and replace it if necessary
 Check if there is good thermal contact between the temperature
sensor and the measured surface,
 whether the sensor lead is not placed too close to the mains
cable,
 If the sensor is connected to the terminal,
 Whether the sensor is not damaged – check it in accordance with
point 11.8
 Increase the parameter Extending hot utility water pump
operation (r4) in order to cool down the boiler
 Set the parameter Extending hot utility water pump operation
(r4= 0)
 The reason can be a constructional defect of the boiler,
consisting in lack of protection against too high chimney draught
(no back shutter in the fan, or damaged shutter), or the boiler is
not tight.
