CENTRAL HEATING SYSTEM CONTROLLER
MANUFACTURER: P.H.P.U. AS, Polanka 8a/3, 1-131 Poznań, POLAND
1 INTRODUCTION
Carefully study this user manual to learn how to correctly operate the EUROSTER 11W central
heating system controller.
2 FIELD OF APPLICATION
EUROSTER 11W is a modern microprocessor- ased controller used to control central heating
(CH) systems with coal/culm-fired low oilers.
The controller measures the oiler water temperature and depending on its relation to the
preset temperature respectively adjusts flow of the air supplied to the oiler furnace and turns
ON/OFF the CH system circulation pump.
The EUROSTER 11W controller features the ANTY STOP
function that prevents idle pump rotors against seizing. Once
the heating season is over, every 14 days the function
automatically turns ON the pumps for 30 seconds. To that
end the controller must e left powered up.

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 11W 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 else on an unshielded oiler outlet pipe (as close to the oiler as possi le)
using hose clips tighten the sensor to its pipe and cover it 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) Hook up fan 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.
e) Verify the connections:
check up all ca le connections and tighten terminal ox lids.
f) 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.

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 function turns on 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.
EUROSTER 11W USER MANUAL 4
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. Boiler preset temperature
The controller will attempt to maintain this temperature manipulating oiler fan and CH
pump.
2. Fan hysteresis
Temperature range, in which controller linearly adjusts fan power. The narrower the
preset hysteresis, the smaller fluctuations of the CH system temperature will e.
However, a too narrow preset will make the temperature to oscillate – the controller will
alternately heat up and cool down the oiler.
Initially set the maximum allowa le hysteresis, wait until the preset temperature is
reached and check if (in such conditions) the fan operates at a power level etween set
points Błąd: Nie znaleziono źródła odwołania and Błąd: Nie znaleziono źródła odwołania.
If so, the hysteresis may e narrowed down.
3. Minimum fan power
The lowest power at which the fan may operate. Should e selected experimentally as
the power, at which the fan rotor starts to rotate (see fan test function, set point 11).
4. Maximum fan power
The highest power at which the fan should operate. Should e selected experimentally
as the power, at which the actual oiler temperature (maintained y the controller) was
as close to the preset temperature as possi le.
5. Blowdown time
The fan is turned ON for that period if the controller needs to low down the furnace (to
remove com ustion gases out of the oiler). Blowdown time should e long enough to
effectively exhaust the gases via the chimney, ut on the other hand short enough to
prevent oiler temperature rise.
. Gap between successive blowdowns
Time after the last lowdown cycle efore a new cycle may e started. It should e long
enough to prevent oiler temperature rise, ut on the other hand short enough to avoid
explosive com ustion of the oiler gases.
7. CH pump TURN ON temperature
See section 11 for detailed description of conditions in which CH pump is turned
ON/OFF.
8. CH 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 11 elow for details.
EUROSTER 11W USER MANUAL 5
9. 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.
10.Put out temperature
As soon as actual oiler temperature has dropped elow that preset, the controller
turns the oiler OFF (the oiler furnace is most pro a ly put out). A too high put out
temperature preset
may cause the controller to turn the oiler OFF mistakenly.
11.Fan manual operation (test)
Display current fan status commanded y the controller (0…100%). Press the kno and
modify the parameter value to manually control the fan. Press the kno once more or
leave it inactive for 10 seconds to resume automatic mode of control.
12.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.

1) The controller displays values calculated y its algorithm.
9 FIRING UP
During the oiler firing-up phase the pump is disengaged and the fan is operated at its highest
power level in order to speed the process up as far as possi le.
The firing up procedure may be initiated exclusively while the controller is in the put-
out mode – fan is not operating, no flame icon is visible on the display.
To initiate the procedure:
turn the controller kno all the way to the left, then press it and hold down until the fan
is started, or
turn the controller power OFF then ON.
The procedure is terminated when:
the oiler temperature is closer to the preset (Błąd: Nie znaleziono źródła odwołania)
than half of the hysteresis (Błąd: Nie znaleziono źródła odwołania, )or
within 1 hour the oiler has not reached the preset put-out temperature (Błąd: Nie
znaleziono źródła odwołania).
If for any reason (e.g. self firing up) the temperature of a put-out oiler exceeds the preset
put-out temperature (Błąd: Nie znaleziono źródła odwołania), the controller will automatically
EUROSTER 11W USER MANUAL 6
resume normal operation i.e. pumps will not e turned OFF.
10 FUELING
The fan should e turned OFF for the time the oiler furnace is loaded with new fuel. To this
end turn the controller kno all the way to the left while the controller is in its normal
operation mode (flame icon visi le on the display), then press the kno and hold it down until
the flame icon disappears. Fan icon starts to link alternately with a hand icon – it means that
the fan was manually disengaged (all other algorithms are operating normally).
Proceed as a ove to turn the fan ON. Once the fan is ack ON, the controller initiates the firing
up cycle – it turns the pump OFF in order to fire the new atch of fuel up as soon as possi le.
Should the flame to extinct, the controller will automatically turn the fan OFF.
ATTENTION: The controller will not automatically turn the fan OFF if it was earlier
manually turned OFF by the user and not turned back ON.
11 CONTROLLER OPERATION
The controller attempts to maintain oiler temperature adjusting amount of air lown to the
furnace y the fan and turning the CH pump ON/OFF.
Cold oiler may sweat during the firing-up period. Therefore the fan is operating at the highest
power level (preset Błąd: Nie znaleziono źródła odwołania) and the pump is OFF to shorten
that period as far as possi le.
As soon as the oiler temperature has approached the preset (and is within the hysteresis
corridor), the controller starts to smoothly control air flow adjusting the fan power level. Fan
power range is limited y the minimum fan power (Błąd: Nie znaleziono źródła odwołania) and
the maximum fan power (Błąd: Nie znaleziono źródła odwołania) presets.
Should the oiler temperature to exceed the upper threshold, the controller will start the oiler
lowdown cycling. In that mode the fan is used only to remove com ustion gases out of the
furnace. Blowdown cycle parameters should e set so that oiler temperature will drop down
to the level at which the controller will e a le to resume linear control of the fan power.
Should the oiler temperature to exceed the alarm temperature, the fan will e turned OFF for
good. Overheating is signaled y pulsing of the controller display.
Should the oiler temperature to drop down elow the put-out preset (Błąd: Nie znaleziono
źródła odwołania), the fan will e turned OFF. The pumps will e operated normally.
The CH pump is engaged as soon as oiler temperature T oiler exceeds oiler preset
temperature Tpreset y more than half of hysteresis Hpump:
Toiler > Tpreset +Hpump/2
The pump is disengaged as soon as the temperature drops down elow the preset y more
than half of the hysteresis:
Toiler < Tpreset – Hpump/2
12 THE ANTY-STOP FUNCTION
The ANTY-STOP function turns on the pump immediately after the controller is turned on, then
every 14 days. “AS” letters are linking on the controller display while the function is active.
Any alarm generated while the ANTY-STOP function is active (overheating or temperature
sensor failure) a orts the function execution.
13 TROUBLESHOOTING
a) Device is dead
Burnt mains fuse or ROM failure. Replace the fuse or have the controller serviced.
b) Sensor icon on the display blinks, “Sh” or “OP” letters next to the icon
Sensor circuit shorted (Sh) or opened (OP). Check/replace the sensor ca le or ship the
controller (together with the sensor) to service.
EUROSTER 11W USER MANUAL 7
c) Pump or fan does not operate
Turn on the controller and make sure that pump/fan icons are displayed. If so, check
pump/fan connections. Check if the fan was not turned OFF manually, see section 10. Check
presets or restore factory ones (see section Błąd: Nie znaleziono źródła odwołania)
d) Fan is operating continually
Blowdown gap (Błąd: Nie znaleziono źródła odwołania) set to 0 – correct the preset.
e) Boiler is overheating
Blowdown time (5) too long or lowdown gap (6) too short – correct the preset.
