EUROSTER 1100WB
1. FUNCTION
Euroster 1100WB is a modern controller to be used in the central heating systems where
blowing boiler powered by solid fuel. A basic function of the controller is to optimise the
combustion process by a series of settings and modifications. It has inputs for controlling
a circulating pump and a blower as well as an option for connecting a room regulator.
EUROSTER 1100WB is equipped with ANTI STO system that prevents seizure of
the pump rotor in the idle periods. Throughout the non-heating season the controller
E ROSTER 1100WB automatically cycles the pumps for 30 seconds. For this function to
be operational, the controller must not be switched off at the end of the heating season.

below where the cables are appropriately marked. Namely, neutral cables should
be screwed to terminals N, phase cables to terminals L, and protection cables to
terminals PE.

+10ºC.
g. setting the blower rotations
•press the function key (F) until the diode OBROTY will start blinking. Switches (+)
and (–) change the value of the setting code and set a required value of the
blower rotations. Blinking digits show a code from 0 to 9 which determines the
value of the blower rotations settings in operation. Depending on the needs the
force of blowing is determined with the use of this parameter ranging from 0 to 9,
where 0 means MAXIMAL and 1 - MINIMAL rotations of the blower.
h. blowing time adjustment
•press the function key (F) until the diode PRACA will start blinking and the display
will show a code from 0 to 9 which determines the time value of current setting in
accordance with the table below.
•set the cyclic blowing – right switch (extending) or left switch (shortening)
•wait ca. 5 seconds until the setting has been stored and the display will show the
current temperature will show the current temperature of the central heating
sensor
i. blowing interval adjustment
•press the function key (F) until the diode PRZERWY starts blinking and the display
shows a code from 0 to 9 which determines the time value of current setting in
accordance with the table below.
•set the blowing interval – right switch (extending) or left switch (shortening)
•wait ca. 5 seconds until the setting has been stored and the display will show the

5. O ERATION OF THE CONTROLLER
a. mode: heating and cooling
•E1100WB is equipped with the heating function that is activated by the on/off
mains switch. This function is operational just after switching on the controller.
The controller checks the temperature of water in the boiler and when due to the
heating the temperature of the central heating sensor reaches the preset
temperature for the blower (the value preset for +10°C), the heating function will
be switched off and the controller will start its operation in accordance with the
settings. During the heating mode the controller does not receive information
from the external input (room regulator) and does not activate the pumps,
whereas the blower operates according to the user’s settings. When the
temperature in the boiler does not increase above 30ºC for 60 minutes, then the
controller will switch off the blower and activate the sound alarm for 20 minutes
(the furnace has cooled down). Another increase of temperature will cause the
blower to activate (heating) and operate according the user’s settings.
b. mode: controlling
•After heating up the boiler the controlling mode starts when the controller
operates according to the settings. Central heating pump is activated when the
temperature of the central heating sensor reaches the preset temperature. The
pump will be switched off if the temperature falls below the value set by 5ºC. Due
to activated DHW priority the central heating pump will be operational only when
the DHW pump is switched on.
The blower is activated when the temperature in the boiler decreases below the
preset temperature. In case when the temperature of the sensor reaches the
preset temperature, then the controller reduces its rotations every second until a
compete stop. When the measured temperature is above the preset temperature
then the process of cyclic activation of the blower will start in order to blow the
furnace. When exceeding the temperature of 85ºC the process of furnace blowing
will be inactive and the controller will start the alarm mode, absolutely activate
the central heating pump and start the acoustic signal (buzzer).
c. controlling the DHW pump and operation according to the priority
•Euroster 1100WB has a priority of heating DHW with a function of protecting the
DHW cylinder against cooling. During heating up the cylinder the controller does
not receive information from the room regulator and in this situation it will try to
heat the cylinder as soon as possible. Irrespective of other algorithms the blower
temperature will be automatically increased by 10ºC above the temperature
preset for the DHW pump. The pump is activated if the temperature of the
cylinder sensor is below the setting and the central heating temperature is 10ºC
above the current temperature of the DHW sensor. If the temperature increases
and reaches the preset temperature for the cylinder or when the temperature of
central heating sensor is equal or below the current temperature of the DHW
sensor, then the pump is switched off.

d. weather controlling
•The algorithm of controlling the blower has two separate setting temperatures
(the preset temperature of the blower for the external temperatures of: +10ºC
and -20ºC) which are used by the internal room regulator when determining the
current temperature of the blower in operation. With the use of these two settings
the controller determines the heating curve shown below.
ATTENTION !
In order to switch off the weather regulator, the same values should be set for
both settings.
Dependence of the current temperature of blower operation on the temperature outside.
e. room regulator
•The controller is equipped with an input for a room regulator. If the regulator
requires heat (shorted contacts), it means that the boiler is to operate and heat
up – the central heating pump and the blower operate according to the user’s
settings in order to maintain the preset temperature. Whereas when there is not
need for heat (opened contacts), the controller modifies the settings in order to
maintain the boiler temperature at 40ºC. The algorithm of the ventilator operates
with the preset temperature of 40ºC, cyclic blowings are active and the central
heating pump is activated.
f. operation without the DHW pump
•When a user is not going to use the function of heating the DHW, then in the place
of a DHW temperature sensor resistor at a value of 2,2 kΩ (included in the set)
should be mounted and set the temperature of the DHW pump at the minimal
value (eliminates the DHW priority function).
g. operation during the non-heating season
•In order to switch of the central heating during the non-heating season, the
temperature for the central heating pump should be set at 90ºC (above the
setting for DHW and the blower) and then only the cylinder will be heated. The
temperature set for the blower will be automatically increased by 10ºC above the
preset temperature for the DHW pump so that cylinder will be heated as fast as
possible.
