1. INTRODUCTION
In order to guarantee correct operation of central heating and hot usable water controller and
installations one should familiarize oneself with the present user manual.
2. INTENDED USE
EUROSTER 11Z is a modern controller that independently controls operation of two pumps:
central heating circulating pump and hot water tank loading pump with the possibility of
prioritizing hot water pump.
The controller switches off central heating pump if temperature of the heating boiler falls below
a predefined value.
If tank temperature falls down, tank loading pump will be switched off. Moreover, the controller
protects the tank against cooling down in case of low temperature of boiler extinction. Hot
water priority function allows for the fastest possible way of heating the tank.
3. CONTROLLER FUNCTION
•prevents boiler sweat
•keep constant temperature in the tank
•switches on the hot water priority function
•blocking function against tank cool down
•anti-stop function to protect pumps against stoppage
•frost protection
•pump operation test
•temperature reading correction
The EUROSTER 11Z controller has been equipped in an ANTY STOP system to prevent seizing
of rotors of unused pumps. After finishing heating season it automatically launches the pumps
for 30 seconds every 14 days. In order for the system to work out of season, the controller
must be left on.

5. CONTROLLER ASSEMBLY
On outlet cables of the controller there is voltage at life hazard level therefore
energy supply should be switched off during installation and only qualified
people should perform assembly. Do not assemble a controller with
mechanical damage.
a) fixing the controller:
•fix the controller on a wall and other support with the use of two screws (rawbolts with
screws come with the regulator),
•attach the cables lead out of the controller to the wall with the use of grips.
b) fixing sensors:
•sensors must not be immersed in liquids and installed on exhaust fume outlets
to the chimney,
•install boiler temperature sensor in an appropriate place on the boiler or in an
uncovered part of central heating pipe (as close to the boiler as possible),
•install temperature sensor of the tank in an appropriate place in the tank,
•press the sensors to the pipe with the use of bands, put thermal insulation on.
c) connecting supply cables to the pumps:
•connect yellow or yellow-green conductor (protective cable) to the clamp ( ),
•connect blue conductor to the clamp (N),
•connect brown conductor to the clamp (L),
d) checking the connection:
•check whether the cables have been connected correctly and turn pump clamp box
covers.
e) connecting the controller:
•after securing cables against accidental rupture, connect power supply cable to
230V/50hz socket with earthing pin.

8. RESTORING FACTORY SETTINGS / PERMANENT SCREEN LIGHT-UP
If it is needed to restore factory settings, the following steps should be taken:
•Keep the knob pressed and turn the controller on and off. "Fd" (Factory defaults) will
appear on the screen, once the knob is released, 0 will appear.
•Use the knob to select 0 or 1 and confirm.
•By selecting 0 you will be able to change screen backlight functions without restoring
factory defaults. By selecting 1 you will restore factory defaults.
•Next, "bl" (Backlight) will appear on the screen, once the knob is released, 0 will
appear.
•Use the knob to select 0 or 1 and confirm. Selecting 0 will result in automatic screen
backlight switch off after 1 minute of finishing controller operation, and selecting 1 will
result in permanent screen backlight.
•control and possibly correct the remaining controller settings.
In case of lack of confirmation within 5s the controller resumes operation as if no changes
have been introduced.
9. CONTROLLER SETTINGS
After being switched on the controller shows system condition. Turning the knob right result in
entering setting overview and change mode.
Controller configuration follows a method specified below: Chose the required parameter by
turning the knob. The controller will show the value (at the top) and number (at the bottom).
In order to change value of the shown parameter, push the knob (parameter value will start
pulsing), set the required value and confirm selection by pressing the knob. If the value should
not be changed (cancellation of changes), do not push the knob, but wait 10 seconds for the
setting to stop pulsing.
Setting windows have been number for convenience.
User can change the following parameters:
1. Central heating circulation temperature
This is medium temperature for central heating pump to switch on.
2. Central heating circulation hysteresis
Temperature difference at which central heating pump is switched on and off.
Conditions for pump switching on and off have been described in detail in chapter 10.
3. Hot water tank temperature
This is tank temperature that the controller is trying to keep.
REMARK: Keeping low tank temperature (about 35-40ºC) facilitates development of
bacteria including Legionella.
4. Tank temperature regulation hysteresis.
Hysteresis is equal to temperature difference at which the controller switches the pump
on and off. Conditions for pump switching on and off have been described in detail in
chapter 10.
5. Temperature difference between heat source and the tank
Heat source should have a higher temperature than the tank for two reasons: First, to
guarantee appropriate heating efficiency and second, to compensate heat losses
resulting from imperfect insulation of pipes connecting the boiler and the tank. If heat
source temperature is not high enough, hot water tank loading pump will not be
switched on.
6. Hot water heating priority
If hot water heating priority is switched on, the controller directs all the available power
for heating the tank. Therefore, till the moment the tank is heated up, central heating
circuit is switched off.
7. Reading correction - heat source temperature
This is the value which is added or deduced from the measured temperature. it allows
for correction of readings between the sensor placed on the pipe and the thermometer
on the boiler.

8. Reading correction - tank temperature
This is the value which is added or deduced from the measured temperature. it allows
for correction of temperature difference between the sensor placed on the pipe and
water temperature.
9. Central heating pump operation / test
it shows current pump condition, calculated by the controller (0 or 1).
Outlet testing function can be switched on by pressing the knob. After 10s of inactivity
or after pressing the knob again, the controller resumes operation according to its
settings.
10.Hot water tank loading pump operation / test

10. CONTROLLER OPERATION
The controller constantly monitors tank and boiler temperatures.
Central heating pump will be switched on, if temperature exceeds settings by half of the set
hysteresis value Tboiler ≥ Tset cent.heat. + H cent.heat./2
Central heating pump will be switched off, if temperature falls below settings by half of the set
hysteresis value Tboiler ≤ Tset cent.heat. - H cent.heat./2
The decision on switching hot water tank pump, on the other hand is taken in two steps:
•Tanks should be heated, if tank temperature is lower than the set value about at least
half of the hysteresis value, Ttank ≤ Thot.water.set. - H hot.water./2 In such a case, if hot water
priority is on, operation of central heating pump is interrupted.
Tank heating can be interrupted, if tank temperature is higher than the set value about
at least half of the hysteresis value, Ttank ≥ Thot.water.set. + H hot.water./2
•The pump can be switched off without risking cooling down, if heat source temperature

EUROSTER 11Z –USER MANUAL 6
is higher than tank temperature by at least the setting Difference (5.) + 3°C, Tboiler –
Ttank≥ Tdifference + 3
The pump cannot be switched off (it will result in cooling down the tank), if heat source
temperature is not higher than tank temperature by at least the setting Difference
(5.) - 3 °C, Tboiler –Ttank≥ Tdifference - 3
Protecting the tank against overheating
If the tank is loaded by another, supplementary heat source and if tank temperature exceeds
85°C, then the central heating loading pump will be switched on until tank temperature falls
below 85°C.
Special attention should be paid when using hot water to avoid burning.
Feeder alarm temperature.
Once alarm temperature (90°C) is reached at heat source sensor, central heating and hot
water pumps will be switched off regardless of priorities. Screen backlight keep pulsating until
the temperature falls down.
Frost protection
Frost protection function gets activated when temperature of a given sensor falls to 4°C. If
boiler sensor (central heating) reaches such a temperature, central heating and hot water
pumps are activated and "AF" (Anti freeze) gets displayed on the screen. In case of tank
sensor (hot water) only hot water pump is being switched on. Protection is switched off, when
the temperature raises above 6°C.
11. ANTY-STOP
Pump anty-stop system switches the pumps on for 30 seconds immediately after each
controller switch on (also after restoring to factory default or change of backlight mode) and
then every 14 days. During its operation, "AS". keeps pulsating on the screen.
If during activity of the ANTY STOP system an emergency situation occurs (overheating or
damage to the sensor), operation of the ANTY STOP system will be interrupted.
12. TYPICAL DAMAGES AND REPAIR METHODS
Device is not working
Burnt fuse or memory software fault - send the device to service.
Screen and sensor symbol blinking, "Sh" or "OP" appears
Short sensor (Short) or open sensor (OPen) - check sensor cable for which a symbol is
pulsating or send the device together with the sensor for service.
