1. INTRODUCTION
In order to ensure proper operation of the controller and the CH system, please read this
manual carefully.
2. APPLICATION
Euroster 10M controller is designed to control the heating circuit temperature (e.g., under-
floor heating) using a mixing valve equipped with a 3-point controlled actuator (230 V).
The temperature is controlled using the P.I. (Proportional-Integral) algorithm, which allows
for quick and precise regulation for various loads.
Furthermore, the device activates the CH pump, cooperates with room thermostats and
controls a gas boiler or other heating device.
3. CONTROLLER FUNCTIONS

EUROSTER 10M – INSTALLATION AND OPERATION MANUAL 3
Install the controller in a place where the temperature does not exceed 40°C. Lead all
necessary cables prior to mounting the controller.
Screw the electric cables to the connectors according to the description and drawing. Make
sure to keep the proper designation of the cables. Screw the neutral conductors to N ter-
minals, phase conductors to L terminals and grounding conductors to PE terminals. Use a
cable with a minimum diameter of 0.75mm² for connection.
CAUTION!
When connecting the power cables, pay particular attention to the correct con-
nection of PE conductors.
The temperature sensors are not suitable to be immersed in liquids.
The controller interacts only with actuators equipped with limit switches.
CAUTION!
Euroster 10M controller and a heat emitting device are connected to the “Boiler”
output and must be powered from the same phase of the power system.

EUROSTER 10M – INSTALLATION AND OPERATION MANUAL 4
b) mounting the controller:
•Install the controller in an electric cabinet (width of 6 modules) on a DIN 35 mm
rail,
•use fasteners to fix controller cables to the wall.
c) Connecting a Room Thermostat
The controller can cooperate with any room thermostat with voltage-free, normally open
(NO) output – e.g. any thermostat manufactured by EUROSTER.
Connection of the controller:
•Make sure that the controller is de-energized.
•Remove the jumper from the REG joint
•Lead a cable (minimum 2 x0.5 mm² stranded wire) between the room thermostat
(or the receiver – in case of connecting the wireless version) and the EUROSTER
10M controller and insulate the cables,
•Screw the cables to the joint,
•connect the cables to COM and NO contacts in the room thermostat.
d) Connecting Temperature Sensors:
The controller temperature sensors may be connected in any way, with no need to keep
cable polarity. At installation avoid leading the sensors parallel to live cables. Moreover,
make sure to provide the proper contact with measured surfaces.
•Install the heating source temperature sensor on the heating source/buffer or the
uncovered outlet pipe of the CH boiler (possibly close to the boiler).
•Install the heating zone temperature sensor on the uncovered pipe downstream of
the CH zone pump.
•Use the hose clips to tighten the sensors to the pipe and insulate them.
e) BOILER output
It is used to switch on the heating source, e.g. gas-fired boiler. It has 3 contacts marked
as NO, COM and NC. They are galvanically isolated from the rest of the system. They
withstand a mains voltage of 230 V and a load of 1 A.
Most commonly, boilers are equipped with the normally open connection (a jumper
must be removed from the heating source), in such cases, you need to connect the
10M controller with COM and NO terminals (the controller has the COM and NO termi-
nals).
The BOILER output is disconnected whenever the room thermostat achieves the preset
temperature or the supply temperature alarm occurs.
f) Connecting the mixer actuator
•Connect the neutral cable of the mixer actuator to the N terminal
•Connect the cable responsible for closing the mixer (decreasing the temperature)
to the Lz terminal
•Connect the cable responsible for opening the mixer (increasing the temperature)
to the Lo terminal
g) Connecting the CH pump
•Connect the yellow or yellow-green wire (protective conductor) to the PE terminal
•Connect the blue wire to the (N) terminal
•Connect the brown wire to the (L) terminal.
h) Connecting the controller to 230 V 50 Hz network
Check the wires and sensors for the correct connection. Having secured the cables
against accidental breaking, connect the power cable to the 230 V 50 Hz mains socket
with an earth pin.

•While holding the √ button pressed, momentarily unplug and then reconnect the
plug to the 230 V mains socket
•“Fd” letters (factory defaults) are displayed and 0 appears after releasing the but-
ton,
•Use buttons to select 0 or 1 and confirm with √.
Selecting 0 enables the change of screen backlight functions without restoring fac-
tory defaults. Selecting 1 restores factory settings.
•Then, “bl” (backlight) is displayed and 0 appears after releasing the button.
•Use buttons to select the required number (0 or 1). Selecting 0 results in the
automatic screen backlight switch-off after 1 minute of finishing operating the con-
troller, and selecting 1 results in the display backlight being continuously active.
•Control and correct the remaining controller settings, if necessary.
•In case of failure to confirm the changes within 5 seconds, the controller resumes
operation without introducing changes.
10. CONTROLLER SETTINGS
After being switched on the controller shows the system status. Press to enter preview
and parameter change mode.

EUROSTER 10M – INSTALLATION AND OPERATION MANUAL 7
The controller configuration is specified below: press buttons to select the desired pa-
rameter. The controller will show the value (at the top) and number (at the bottom). In
order to change the value of the displayed parameter, press √ (the parameter value starts
blinking), set the required value using , and confirm the selection by pressing √. If the
current value is to remain unchanged (cancelling changes), do not press the button, but
wait 10 seconds until the setting stops blinking.
To facilitate the operation of the controller, the configuration windows have been numbered.
The user can change the following parameters:
1. Controlled temperature
It is the temperature of the zone that the controller aims to maintain using the
mixer.
2. Temperature adjustment hysteresis
It is the temperature difference for which the controller starts to close and open
the valve. If the temperature of the controlled zone does not differ from the setting
by more than half of the hysteresis value, the controller will not correct the mixer
position. This avoids unnecessary adjustments to the mixer. You can set the hys-
teresis to zero – in that case, the controller will aim to maintain the temperature
exactly at the preset value.
3. Dynamics
This parameter characterizes the dynamics of the control. If you want the controller
to instantly respond to the temperature fluctuations, increase the dynamics. This,
however, may lead to overcorrection.
Examples of controller responses to a sudden drop in temperature, with dynamics
settings that are too high or too low are shown below.
4. Pump activation temperature
It is the temperature above which the CH pump is activated.
5. Pump hysteresis
It indicates the temperature difference at which the controller turns the CH pump
on and off. The conditions for turning the pump on and off are specified in section
11.
6. Alarm temperature of the CH zone.
This setting allows you to establish the temperature at which the alarm procedures
are activated. If the controller is used in a floor heating system, it is recommended
to set it at 45 ºC.
Caution! Alarm temperatures for zones should be selected carefully. Incorrect set-
ting of temperature level may cause improper operation or major failure of the
system components.

EUROSTER 10M – INSTALLATION AND OPERATION MANUAL 8
7. Temperature of Supply Alarm
Exceeding the alarm temperature on the system’s supply triggers the alarm algo-
rithm, which aims to cool down the boiler.
The alarm algorithm heats the zone to a temperature close to the alarm threshold.
It is essential to ensure that the alarm temperature is at a safe level.
8. Read-out Correction – boiler temperature sensor
It is a value added to the measured temperature value. It allows for compensating
the difference in readings between the sensor placed on the pipe and the ther-
mometer installed on the boiler.
9. Read-out Correction –the controlled zone temperature
It is a value added to the measured temperature value. It allows for compensating
the difference in readings between the sensor placed on the pipe and the heating
medium.
10. Mixer operation/test
Allows for manual operation of the actuator. The numbers stand for the following:
1 – closing the mixer (increasing the controlled temperature)
0 – stopping the mixer
1 – opening the mixer (decreasing the controlled temperature).
To operate the mixer manually press the button and change the displayed value.
After 10 seconds of inactivity or pressing the button again, the controller resumes
operation according to the settings.
11. Pump operation/test
Displays the current status of the pump calculated by the controller (0 or 1).
To operate the pump manually press the button and change the displayed value.
After 10 seconds of inactivity or pressing the button again, the controller resumes
operation according to the settings.
ATTENTION: In case the set values preclude the correct operation of the control-
ler, 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 re-
stored.

11. CONTROLLER OPERATION
The controller controls the temperatures of the boiler and the controlled zone. Periodically,
it calculates the difference between the preset and measured temperature.
If the difference between the set and measured temperature exceeds half of the hysteresis,
the position of the mixer is adjusted at a speed determined by the Dynamics (3) parameter.
If the mixer has been activated to operate in the same direction for at least 100 seconds,
the controller permanently turns on the mixer actuator to set it to the extreme position.
After the subsequent 500 s, the mixer actuator will be switched off.
The pump is activated when the boiler temperature exceeds the setting by half of the
hysteresis, Tboiler ≥ Tsetting+ Hpump /2.
The pump is deactivated when the boiler temperature drops below the setting by half of
the hysteresis, Tboiler≤ Tsetting - Hpump /2.
12. ANTI-FREEZE PROTECTION
The anti-freeze protection is activated when the temperature of a given sensor drops to
4°C. If such temperature is detected by a sensor, the pump is activated and “AF” (anti-
freeze) appears on the display. The protection is deactivated when the temperature rises
to 6 °C.
13. OPERATION WITH ROOM THERMOSTAT
Turning off the room thermostat (opening the output) will cause the heating source trans-
mitter to turn off, and the mixing valve to close, followed by switching off the pump.
The connection of a room thermostat was described in point 5c.
14. ANTI-STOP
Each time the controller is connected to a 230 V network (also after restoring factory set-
tings or changing the backlight type), the Anti-Stop function immediately activates the
pump and the mixing valve, later the operation is repeated every 14 days. During its op-
eration, "AT" letters flash at the display.
To avoid the risk of overheating the circuits, the pump is turned off and the mixer is fully
opened. If an alarm situation (overheating or sensor damage) occurs when the Anti-Stop
system is active, the operation of the Anti-Stop system will be ceased.
