EUROSTER 11/11C
CENTRAL HEATING PUMP CONTROLLER
MANUFACTURER: P.H.P.U. AS, Polanka 8a/3, 61-131 Po nań, POLAND
1. INTRODUCTION
Carefully study this user manual to learn how to correctly operate the EUROSTER 11/11C
central heating (CH pump controller.
2. FIELD OF APPLICATION
EUROSTER 11/11C is an electronic controller used to automatically turn ON/OFF CH system
circulation pump depending on CH system water temperature. The pump may circulate water
through a system heated by a coal- or gas-fired boiler. Water temperature is sensed by a
sensor located at the CH system inlet.
The controller will also turn the pump OFF as soon as coal-fired boiler flame is put out. Water
should not be circulated unless it is heated by the boiler since chimney air draft cools down the
boiler water much faster than the radiator water.
Controller is equipped with a knob used to preset optimum CH system water temperature
(most often around 40ºC . If the controller cooperates with a gas-fired boiler, its set
point MUST BE LOWER than the boiler thermostat set point. Set the controller set
point higher than the dew point in order to prevent boiler sweat during the process
of heating the water up.
The EUROSTER 11/11C controller features the ANTY STOP
function that prevents idle pump rotors and valves against
seizing. Once the heating season is over, every 14 days the
function automatically turns ON the pumps and the valves for
30 seconds. To that end the controller must be left powered up.

4. INSTALLATION
Ha ardous voltages may be present inside the controller and on its cables.
Therefore it is expressly forbidden to install the device prior to disconnecting
its mains power supply. Only qualified technicians may install the controller.
Do not install any devices showing signs of any mechanical damage.
The procedure:
a) Mount the controller:
using a pair of supplied nylon nail-it fasteners (anchors mount the controller box on a
wall (or any other suitable supporting structure
using fasteners fix controller cables to the wall.
b) Install temperature sensor:
do not immerse sensor in liquids nor install it within stream of flue gases
install the CH system inlet temperature sensor at the boiler point specially designed for
that purpose or on an unshielded boiler outlet pipe (as close to the boiler as possible
using hose clips tighten the sensor to the pipe.
c) Hook up pump power supply cable:
connect yellow (or yellow-green PE wire with the terminal
connect blue wire with the N terminal
connect brown wire with the L terminal.
d) Verify the connections:
check up all cable connections and tighten terminal box lids.
e) Hook up the controller:
make sure controller cables are protected against incidental cut off
plug the controller power supply cable into a 230V/50Hz mains socket equipped with a
grounding pin.
The controller must not be installed in a place where the ambient
temperature may exceed 40ºC.
5. TURNING THE CONTROLLER ON
Turn the controller mains switch (1 in section 3 into the “I” position.
Green LED (6 in section 3 goes ON
In case of the E11C controller model its ANTY STOP function turns the pump on for
about 30 seconds (red LED goes ON
Using the knob set the desired temperature.
6. AUTOMATIC OPERATION
The EUROSTER E11/11C controller engages/disengages CH system circulation pump
depending on sensor temperature in relation to the knob-preset temperature set point. The
pump is turned ON as soon as sensor temperature exceeds the set point, and is turned OFF as
soon as it drops below the set point.
7. MANUAL OPERATION
Manual pump switch of the EUROSTER E11/11C controller may be useful e.g. to help de-
aerate the system or in case of a failure of the temperature sensor.
1. Turn the continuous operation switch (8 in section 3 into the “I” position (red LED goes ON .
2. The pump will be engaged regardless of the actual sensor temperature in relation to the
controller set point.
8. TROUBLESHOOTING
a) Device is dead (green LED does not go ON)
Burnt mains fuse or ROM failure. Replace the fuse or have the controller serviced.

b) Pump does not operate
Use manual operation switch (8 to turn the pump ON. If the red LED (7 goes ON but the
pump does not operate, check if pump operates when connected directly to a mains socket. If
so, have the controller serviced.
Turn the knob all the way towards minimum temperature and heat temperature sensor. If the
red LED (7 does not go ON, have the controller serviced.
c) Pump continuously engaged
Make sure that manual operation switch (8. is not turned ON.
Turn the knob all the way towards maximum temperature. If the red LED (7 is still ON, have
the controller serviced. Otherwsie (the LED goes OFF but the pump does not stop check the
connections.
9. COMPATIBILITY WITH STANDARDS/CERTIFICATES
The EUROSTER 11/11C controller meets all requirements of the EMC and the LVD EU
Directives. The CE Conformity Declaration is available on the http://www.euroster.com.pl
Internet webpage.

ELECTRONIC WASTE MANAGEMENT INFORMATION
We made every effort to get as a long controller lifetime as possible.
However, the device is subject to natural tear and wear. We ask you to have
a controller that will not meet your requirements any more brought in to an
electronic waste management facility. Electronic waste is collected free of
charge by local distributors of electronic equipment.
Inappropriate management of electronic waste may lead to an unnecessary
environment pollution.
Cardboard boxes should be disposed of at a paper recycling facility.
