EUROSTER 1100K – USER MANUAL 1
EUROSTER 1100K
1. APPLICATION
Euroster 1100K is a processor-based electronic temperature controller designed for
controlling the operation of hydronic heating fireplace system.
The unit has two outputs controlling:
1. circulating pump on the fireplace circuit
2. actuated valve or a second circulating pump for efficient operation in combination
with the hydronic heating circuit.
The controller operates the circulating pump on the fireplace circuit and the valve or the
second pump depending on the water temperature.
The digital sensor measures the temperature of water on the fireplace circuit with
optional splitting into two independent circuits.
EUROSTER 1100K 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 1100K 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:

EUROSTER 1100K – USER MANUAL 2
•the controller is fixed directly to the wall or to any other support with two screws
(plastic plugs c/w screws are part of delivery)
•the cables extending from the controller are fixed 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 on the outside of the fireplace circuit
or on the bare outlet pipe from the fireplace (as close to the fireplace as possible)
•secure the sensor on the pipe with the supplied fixing clip
c. connecting of the power supply cable to the 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 valve (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 box
f. 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
exceed 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 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 – temperature setpoint
•red LED on – valve status
•green LED on – pump status
c. setting the temperatures
•setting the temperature for the valve: press the left-hand switch under the display
– the figures will start blinking and the current setpoint will be displayed
•use the right-hand and left-hand switches to increase/ decrease the displayed
temperature setpoint as appropriate

EUROSTER 1100K – USER MANUAL 3
•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.
•setting the temperature for the pump: press the right-hand switch under the
display – the figures will start blinking and the current 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.
d. automatic operation mode
•set the right hand switch () to 0
•the controller will operate the pump and valve according to the temperature
setpoint.
•in the hydronic heating system the pump is switched on when the temperature
measured by the sensor has risen by 2°C above the setpoint and it is switched off
when the temperature has dropped by 3°C below the setpoint.
e. continuous operation mode:
•set the toggle switches (~) and () to position I
•the pump is continuously on irrespective of the selected operating mode (DHW/
heating) temperature setpoint and the current temperature as measured by the
sensor.
