EUROSTER 11B
UTILITY HOT WATER TANK PUMP CONTROLLER
MANUFACTURER: P.H.P.U. AS, Polanka 8a/ , 61-1 1 Poznań, POLAND
1 INTRODUCTION
Carefully study this user manual to learn how to correctly operate the EUROSTER 11B utility
hot water tank pump controller.
2 FIELD OF APPLICATION
EUROSTER 11B is a modern microprocessor- ased controller used to control utility hot water
(UHW) tank pump. It turns the pump ON if tank water temperature drops excessively.
Additionally, it protects the tank against chilling out in case of a low temperature or extinction
of the oiler.
The EUROSTER 11B controller features the ANTY STOP
function that prevents idle pump rotor against seizing. Once
the heating season is over, every 14 days the function
automatically turns ON the pump for 30 seconds. To that end
the controller must e left powered up.
VISIBLE CONTROLLER ELEMENTS

4 INSTALLATION
Hazardous 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.

EUROSTER 11B USER MANUAL 2
The procedure:
a) Mount the controller:
using a pair of supplied nylon nail-it fasteners (anchors) mount the controller ox on a
wall (or any other suita le supporting structure)
using fasteners fix controller ca les to the wall.
b) Install temperature sensors:
do not immerse sensors in liquids nor install them within stream of flue gases
install oiler temperature sensor at the oiler point specially designed for that purpose
or on an unshielded oiler outlet pipe (as close to the oiler as possi le)
install tank temperature sensor at the tank point specially designed for that purpose
using hose clips tighten the sensors to their pipes and cover them with thermal
insulation.
c) Hook up pump power supply cable:
connect yellow (or yellow-green) PE wire with the terminal
connect lue wire with the N terminal
connect rown wire with the L terminal.
d) Verify the connections:
check up all ca le connections and tighten terminal ox lids.
e) Hook up the controller:
make sure controller cables are protected against incidental cut off
plug the controller power supply ca le 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.

EUROSTER 11B USER MANUAL 3
Animated icon that visually presents state of the heat source (boiler) furnace is for
information purposes only, it does not influence operation of the controller in any
way.
Normal operation: <-> supply temperature etween 35ºC and 90ºC
Overheating: <-> supply temperature > 90ºC
Furnace put out: supply temperature < 35ºC
6 TURNING THE CONTROLLER ON
Turn the controller mains switch (5 in section 3) into the “I” position.
Device firmware version No. and compilation date are sequentially displayed for 2 s.
“AS” letters are linking on the display while the ANTY STOP functions turns on the
mixing valve, then the pump.
State of the system is shown on the display.
If the controller is eing turned on for the first time set the desired controller presets
(see section 8 elow).
7 FACTORY (DEFAULT) PRESETS
Proceed as follows to restore factory presets:
Press the kno and while holding it depressed turn the controller off and on.
”Fd” (factory defaults) is displayed.
Release the kno . Digit 0 is displayed.
Select digit 1 and accept the selection.
Check and correct the presets if needed.
8 CONTROLLER PRESETS
Shortly after power supply of the controller is turned on, current state of the system is shown
on the display. Turn the kno to the right to enter the preset rowse/edit mode. General
procedure to edit a preset:
1. Turn the kno to select the desired preset (parameter). The controller displays current
value of the selected parameter (top) and its num er ( ottom).
2. Press the kno . The displayed parameter value starts to link.
3. Set the desired new value and press the kno to accept it
or
Wait 10 seconds until the displayed parameter value stops linking in order to a ort the
edit procedure (to leave the current value intact)
Configuration windows are num ered to facilitate manipulations. User may edit the following
controller parameters (presets):
1. Tank temperature
UHW tank temperature that the controller will attempt to maintain manipulating the
pump.
ATTENTION: Too low tank temperatures ( 5-40ºC) help to grow various
bacteria within the tank, including the Legionella bacteria.

EUROSTER 11B USER MANUAL 4
2. Pump hysteresis
Difference etween the temperature at which the controller turns the pump on and the
temperature at which the controller turns it off. See section 9 elow for details.
. Boiler-tank temperature surplus
Heat source temperature must e higher than UHW tank temperature for two reasons:
(i) to provide good heat transfer efficiency, and (ii) to compensate for heat losses
etween the oiler and the tank. The “Boiler-tank temperature surplus” preset tells how
much the oiler temperature should exceed the tank temperature in order that the
pump might e engaged. See section 9 for detailed conditions in which the pump is
engaged/disengaged.
4. Boiler temperature sensor correction
A constant added to all values measured y oiler temperature (external) sensor to
compensate for differences in respect to water temperature inside the oiler.
5. UHW tank temperature sensor correction
A constant added to all values measured y UWH tank temperature (external) sensor to
compensate for differences in respect to water temperature inside the tank.
6. Pump manual operation (test)
Display current pump status commanded y the controller (0/1 = pump
disengaged/engaged).
Press the kno and modify the parameter value to manually control the pump. Press
the kno once more or leave it inactive for 10 seconds to resume automatic mode of
control.
ATTENTION: Should a (colliding) value making impossible correct operation of the
controller be preset, then the alarm icon will appear on the display, the colliding
presets will be displayed alternatively, and (after a few seconds) the last correct
combination of presets will be automatically restored.
All presets are listed elow.

9 CONTROLLER OPERATION
The controller continuously compares tank temperature with oiler temperature and turns the
pump ON if the former has dropped excessively. Detailed conditions are as follows:
•The pump is engaged if tank temperature has dropped elow the preset minus half of
pump hysteresis Ttank < Tpreset - Hpump/2. The pump is disengaged if the temperature has
exceeded the preset plus half of the hysteresis Ttank > Tpreset + Hpump/2.
•The pump may e disengaged (without a risk of chilling out the tank) provided that the
difference etween the oiler temperature and the tank temperature is at least y 3 ºC
higher than the preset oiler-tank temperature surplus T oiler – Ttank > Tsurplus+3ºC. The
pump should run (to prevent chilling out the tank) until the difference decreases to the
surplus minus 3ºC, T oiler – Ttank < Tsurplus-3ºC.
