EUROSTER 1100W – USER MANUAL 1
EUROSTER 1100W
1. APPLICATION
Euroster 1100W is a processor-based electronic temperature controller designed for
installation on heating systems incorporating coal/ pulverised coal-fired boilers equipped
with combustion blowers.
In the associated hydronic heating systems the controller will operate the circulating
pump and combustion blower installed under the fire bo .
The digital controller measures the temperature of water in the boiler and operates the
pump and blower accordingly. The operating parameters include cyclic blowing time,
cyclic blowing intervals and fan speed.
EUROSTER 1100W is equipped with ANTISTOP system to prevent seizure of
pump rotor in idle periods. Throughout the non-heating season every fortnight the
integral processor of EUROSTER 1100W will automatically cycle the pump for 30 seconds.
For this function to be operational, the thermostatic controller must NOT be switched off
at the end of the heating season.

2. INSTALLATION
DANGER! Dangerous voltage is present both inside the enclosure and on
the outgoing cables. Prior to installation by a qualified electrician make
sure that the unit has been disconnected from power supply to avoid the
risk of electric shock. Units with mechanical damage should not be
installed.
a. mounting of the controller:
•the controller is fi ed directly to the wall or to any other support with two screws
(plastic plugs c/w screws are part of delivery)

•the cables e tending from the controller are fi ed to the wall with cable clips
b. mounting of the temperature sensor:
•the sensor is NOT intended for immersion in liquids and installation on
breechings (flues between the boiler and chimney)
•install the heating water temperature sensor at the special place on the boiler or
on the bare outlet pipe (as close to the boiler as possible)
•secure the sensor on the pipe by tightening the supplied fi ing clip
c. connecting of the power supply cable to the circulating pump:
•connect the yellow or yellow/green wire (protective conductor) to terminal ( )
•connect the blue wire to terminal (N)
•connect the brown wire to terminal (L)
d. connecting of the power supply cable to the combustion blower (marked with
a blue sleeve):
•connect the yellow or yellow/green wire (protective conductor) to terminal ( )
•connect the blue wire to terminal (N)
•connect the brown wire to terminal (L)
e. check-up of connections:
•make sure the connections have been made as indicated and secure the cover of
the pump motor terminal bo
e. connection of the controller:
•upon securing the cables against accidental pullout, connect the power supply
cable to a 230V/50Hz grounding socket.
IMPORTANT: At the mounting location of the controller ambient temperature should not
e ceed 40ºC.
3. OPERATION
After switching on the controller allow ca. 30 sec. for the controller to become
fully operational
a. start up:
•set the left-hand toggle switch (~) to position I
•upon energising all the segments of the display light up for ca. 2 seconds
•the current temperature, as measured by the sensor is displayed and the
controller operates according to the factory settings (temperature limits of 50°C).
b. description of display functions
•display continuously on – current temperature, as measured by the sensor
•blinking display – settings
•red LED on – blower status
•green LED on – pump status
c. setting the temperatures
•setting the temperature for the blower: press the left-hand switch under the
display – the figures will start blinking and the current DHW temperature setpoint
will be displayed
•use the right-hand and left-hand switches to increase/ decrease the displayed
temperature setpoint, as appropriate
•after ca. 4 sec. the display will stop blinking - this indicates that the preset
temperature has been stored. The display will return to displaying the current
temperature, as measured by the sensor on the heating circuit.

EUROSTER 1100W – USER MANUAL 3
•setting the temperature for the heating water circulating pump: press the right-
hand switch under the display – the figures will start blinking and the current
DHW temperature setpoint will be displayed
•use the right-hand and left-hand switches to increase/ decrease the displayed
temperature setpoint, as appropriate
•after ca. 4 sec. the display will stop blinking - this indicates that the preset
temperature has been stored. The display will return to displaying the current
temperature, as measured by the sensor on the heating circuit.
d. blowing time adjustment
•press and hold the right-hand switch until the figure to the right starts blinking.
The blinking value from 0 to 9 defines the blowing time, as per the table below.
•use the right-hand and left-hand switches to e tend/ shorten the blowing time, as
appropriate
•after ca. 4 sec. the display will stop blinking - this indicates that the setpoint has
been stored. The display will return to displaying the current temperature, as
measured by the sensor on the heating circuit.
e. blowing interval adjustment
•press and hold the left-hand switch until the figure to the left starts blinking. The
blinking value from 0 to 9 defines the blowing interval, as per the table below.
•use the right-hand and left-hand switches to e tend/ shorten the blowing interval,
as appropriate,
•after ca. 4 sec. the display will stop blinking - this indicates that the setpoint has
been stored. The display will return to displaying the current temperature, as
measured by the sensor on the heating circuit.

f. fan speed adjustment
•simultaneously press the two switches under the display until double zero “00”
symbol appears on the display (initially set to ma imum speed). Use the toggle
switches to change the code. During setting codes from 00 to 09 will appear on
the display, which correspond to the blower speed settings for the operating
status (blower is on). The flow rate is set with parameter, where 00 is the
MAXIMUM and 01 is the MINIMUM fan speed.
•use the right-hand and left-hand switches to set the desired fan speed,
•after ca. 4 sec. the display will stop blinking - this indicates that the setpoint has
been stored. The display will return to displaying the current temperature, as
measured by the sensor on the heating circuit.
g. automatic operation mode
•set the right hand switch () to 0
•circulating pump - the controller will switch on the pump when the temperature
measured on the sensor has e ceeded the setpoint by 2°C and switch it off when
the temperature has dropped by 3°C below the setpoint
•combustion blower – the controller features “initial burning” function activated
with the power switch. Upon each switching on the controller will check the
temperature of water in the boiler. If within an hour the temperature has not risen
above 30C the controller will switch off the blower (flame e tinction). If the
boiler temperature has risen up to the setpoint for the blower the “initial burning”
mode will be switched off and the user defined settings will be applied.

EUROSTER 1100W – USER MANUAL 4
The blower is switched on when the temperature has dropped by 3°C below the setpoint.
Then the temperature measured by the sensor has e ceeded the setpoint the switching
off procedure will be initiated. The fan speed will be reduced gradually, in three steps,
finished in step No. 4 when the speed is reduced to zero. When the temperature
measured by the sensor has e ceeded the setpoint the blower will be operated according
to blowing cycles. When the measured temperature has e ceeded 90°C firebo blowing
will be discontinued. When the temperature has dropped below 30°C as a result of flame
e tinction the blower will be switched off. When the temperature has risen again the
blower will be restarted (initial burning phase).
h. continuous operation mode:
•set the toggle switches (~) and () to position I,
•the pump is continuously on, irrespective of the temperature setpoint and the
current temperature, as measured by the sensor.
