1. INTRODUCTION
In order to ensure proper operation of the controller and of the CH system, please read this
manual carefully.
2. APPLICATION
EUROSTER 11W is a state-of-the-art microprocessor-based controller designed for
interoperation with Central Heating (CH) coal- and pulverized coal-fired boilers in systems
equipped with furnace blowers.
The controller measures the temperature of water in the boiler and adjusts the air flow to the
furnace and controls the operation of the CH circulation pump.
EUROSTER 11W controller is equipped with an ANTI-STOP function that prevents
seizing of an idle pump rotor. It automatically turns the pump on for 30 seconds every
14 days when the heating season is over.
Keep the controller turned on to allow the function operation after the heating season.
3. CONTROLLER FUNCTIONS

temperature of the furnace dropped below the shutdown temperature (setting No. 10).
7. TURNING THE CONTROLLER ON
⚫ Turn the controller power switch (5) into the "I" position.
⚫ A device firmware version number and its compilation date are sequentially displayed
for 2 seconds after turning on.
⚫ The Anti-Stop function turns the pump on for 30 seconds – “AS” letters are blinking on
the display.
⚫ The system status is presented at the display.
⚫ Adjust the controller settings when turning the controller on for the first time (section
9).
8. RESTORING FACTORY SETTINGS / PERMANENT LIGHT-UP OF THE DISPLAY
Proceed as follows to restore factory settings, if needed:
⚫ Keep the knob pressed and turn the controller off and on. "Fd" (Factory defaults) will
be displayed and once the knob is released, 0 will appear.
⚫ Use the knob to select the number (0 or 1) and confirm.
Selecting 0 enables to change screen backlight functions without restoring factory
defaults. Selecting 1 restores factory settings.
⚫ "bl" (Backlight) will be displayed and once the knob is released, 0 will appear.
⚫ Use the knob to select the required number (0 or 1) and confirm. Selecting 0 results in
automatic screen backlight switch off after 1 minute of finishing operating the
controller, and selecting 1 results in permanent backlight of the display.
⚫ Control and possibly correct the remaining controller settings.
In case of lack of confirmation within 5 seconds, the controller resumes operation without
introducing changes.
9. CONTROLLER SETTINGS
After being switched on the controller shows the system status. Turn the knob right to enter
the setting preview and change mode.
The controller configuration is specified below: Turn the knob in order to choose the required
parameter. The controller will show the value (at the top) and number (at the bottom). In
order to change the value of the displayed parameter, push the knob (the parameter value will
start blinking), set the required value and confirm the selection by pressing the knob. If the
current value should not be changed (cancellation of changes), do not push the knob, but wait
EUROSTER 11W – USER MANUAL 5
10 seconds for the setting to stop blinking.
Setting windows are numbered for convenient operation of the controller.
The user can change the following parameters:
1. Boiler target temperature
It is the temperature of the boiler to be maintained by the controller.
2. Hysteresis of the blower operation
This is a temperature range in which the controller linearly adjusts the blower power.
The narrower the temperature range, the smaller the system temperature fluctuations.
However, a too narrow range may result in the temperature oscillation – the controller
will alternately heat up and cool down the boiler.
At the time of installation, set the maximum hysteresis value. Then wait for the system
to reach the preset temperature. If, under such conditions, the blower operates at a
power level between settings No. (3) and (4), the hysteresis may be reduced.
3. Minimum power of the blower
This is the lowest power at which the blower may operate. It should be set at minimum
value at which the blower rotor starts to rotate. This value should be selected
experimentally using the blower test function (setting No. 11).
4. Maximum power of the blower
This is the highest power at which the blower may operate. The value should be
selected experimentally so that the boiler temperature maintained by the controller is
as close to the preset temperature as possible.
5. Blow-through time
This is a period of the blower operation in the blow-through mode. The blower is turned
on in order to remove combustion gases from the boiler. The blow-through time should
be long enough to effectively exhaust the gases via the stack and short enough to
prevent the boiler temperature rise.
6. Time interval between successive blow-throughs
This is the time passing between the end of the blow-through cycle and the start of a
new cycle. It should be set so that to prevent the boiler temperature rise, but on the
other hand to avoid explosive combustion of the gases generated in the boiler.
7. CH pump operation temperature
The conditions of turning the pump on and off are specified in section 12.
8. CH pump hysteresis
This is a differential temperature at which the controller turns the pump on and off.
The conditions of turning the pump on and off are specified in section 12.
9. Temperature readings correction
This is a value added to or subtracted from the measured temperature value. It enables
to compensate for the difference in readings between the sensor placed on the pipe and
the thermometer installed on the boiler.
10. Shutdown temperature
This is a temperature below which the controller turns the boiler off (the boiler furnace
is most probably shut down). A too high shutdown temperature preset may cause the
controller to turn the boiler off by mistake.
11. Blower operation / test
Displays the current status of the blower calculated by the controller (0-100 %).
Press the knob to activate testing of the output. Press the knob again or leave it
inactive for 10 seconds to resume automatic operation.
12. Pump operation / test
Displays the current status of the pump calculated by the controller (0 or 1).
Press the knob to activate testing of the output. Press the knob again or leave it
inactive for 10 seconds to resume automatic operation.
ATTENTION: In case the set values preclude the correct operation of the controller,
the alarm icon will appear on the display, and the colliding settings will be displayed
alternately. After a few seconds the last correct configuration is restored.

10. FIRING-UP
During firing-up in order to heat up the boiler as fast as possible the blower is operated at its
highest power level.
The firing-up procedure may be initiated exclusively when the controller is in the
shutdown mode – the blower is not running and the flame icon is not displayed.
Firing-up can be initiated in two ways:
⚫ turn the controller knob all the way to the left, then press it and hold down until the
blower is started;
⚫ turn the controller power off and on.
Firing-up is terminated if:
⚫ the boiler temperature is lower than the set temperature (1) by at most a half of the
hysteresis value (2);
⚫ within 1 hour the boiler has not reached the set shutdown temperature (setting
No. 10).
If for any reason the temperature of the shutdown boiler exceeds the set shutdown
temperature (setting No. 10), e.g. by self firing-up, then the controller will automatically
resume the normal operation mode, i.e. the pumps will not be turned off.
11. FUELING
Turn the blower off for the time the furnace is loaded with new fuel. For this purpose turn the
knob all the way to the left while the controller is in the operating mode (flame icon displayed),
then press the knob and hold it down until the flame icon disappears. The blower icon and the
hand icon are blinking alternately, which means that the blower was turned off manually; all
other algorithms are operating normally.
Proceed as above to turn the blower on. After turning the blower on again, the controller
initiates the firing-up mode (turns the pump off) in order to fire up the new batch of fuel as
soon as possible. If the fire goes out, the controller will turn the blower off.
EUROSTER 11W – USER MANUAL 7
ATTENTION: The controller will not turn the blower on automatically if it was
previously manually turned off by the user.
12. CONTROLLER OPERATION
The boiler temperature is maintained by adjusting the amount of air blown and by controlling
the CH pump.
In the firing-up mode when the temperature is low and the boiler may sweat, the blower is
operating with its full power (determined by setting No. 4). Thus the firing-up period is as
short as possible.
If the boiler temperature is close to the set temperature, within the hysteresis range, the
controller adjusts the air flow smoothly. The range of the blower power control is limited by
two settings: the minimum blower power (3) and the maximum blower power (4).
Exceeding the boiler temperature results in turning into the blow-through operation. In this
operation mode the blower is started only to remove combustion gases out of the furnace.
Blow-through cycle parameters should be set so that the boiler temperature drops to the level
at which the blower operates with a linear rotational speed adjustment.
If the boiler temperature exceeds the alarm temperature, the blower is turned off
permanently. Display blinking indicates overheating.
The boiler temperature drop below the shutdown temperature setting (setting No. 10) turns
the blower off. The pump operates according to the setting (No. 7).
The CH pump is turned on if the boiler temperature exceeds the preset value by a half of the
set hysteresis T boiler ≥ TCH + HCH /2
The CH pump is turned off if the boiler temperature drops below the preset value by a half of
the preset hysteresis T boiler ≤ TCH - HCH /2
Power Alarm Temperature
In case the temperature measured by the boiler sensor exceeds the alarm temperature
(90 °C), the blow-throughs are turned off, and additionally the thermal protection feature
interrupts the blower power supply until the temperature drops to 60 °C.
Frost protection
The frost protection function is activated when the temperature of the sensor falls to 4 °C. If
the boiler sensor (CH) reaches such temperature, the CH pump is activated and "AF" letters
(Anti-Freeze) are displayed.
13. ANTI-STOP
Each time the controller is turned on, the ANTI-STOP function immediately turns the pump on
for 30 seconds (also after restoring factory defaults or change of the backlight type); later the
operation is repeated every 14 days. "AS" letters are blinking on the display while the function
is active.
Any alarm generated while the ANTI-STOP function is active (overheating or sensor damage)
suspends the function operation until the alarm is over.
14. TROUBLESHOOTING
Device does not work
Burnt fuse or ROM failure – send the device to the service.
