1. APPLICATION
EUROSTER 12 is a universal controller designed to control a heating system.
It is equipped with three independently operating control outputs (relays). Based on the
measured temperatures or time, the controller switches on and off a relay for each output.
Flexible arrangement enables adaptation of the controller to the needs of the majority of
systems. Each of the controller outputs may be set up to interact with:
central heating circulation pump
domestic hot water tank feeding pump
domestic hot water zone circulation pump
floor heating pump
blower (no speed adjustment)
any device (thermostat mode, time-based operation mode).
All parameters are shown on a readable graphical display and the device is very easy to
control with a knob and a button.

f. Feeding
Setting of the alarm temperature value for the feeding temperature sensor. Upon
exceeding this temperature, an alarm of feeding overheating is generated. CH, DHW,
floor outputs are switched on until the decrease of the feeding temperature below the
preset alarm temperature. Range from 60°C to 110°C.
8. Description of the operation modes
The following diagrams are simplified and do not cover all the elements necessary for the
correct operation of the system.
a. CH MODE – OPERATING THE CENTRAL HEATING CIRCULATION PUMP
Designations:
1. Feeding temperature sensor
2. CH zone pump
3. The zone temperature sensor for
which the CH mode was selected.
Operating conditions:
The CH pump is activated if:
the CH system is switched on;
the current time is selected in the schedule;
the temperature of the feeding sensor reaches the value of the "Switch-on
temperature" setting.
The CH pump is deactivated if the temperature of the feeding sensor drops by the
hysteresis value below the "Switch-on temperature" setting.
The weekly schedule of the CH pump operation enables switching the zone off for the
selected hours in the selected days of the week.
The zone overheating alarm is generated if the temperature of the zone sensor
exceeds the value of the "Alarm temperature" setting. If the alarm temperature is
maintained longer than for one minute, then the zone pump is switched off.
In the case when the hourly schedule for the pump operation is not marked (heating
not needed), the pump operates in cycles, according to the "Operating time" and "Idle
time" settings. If "Operating time" = 0 is set, then the pump is not switched on.
Caution! When setting the alarm temperature, special precautions must be taken in order
not to damage the system or CH boiler.

b. DHW MODE – CONTROL OF THE DOMESTIC HOT WATER TANK FEEDING PUMP
Designations:
1. Feeding temperature sensor
2. DHW tank feeding pump
3. The tank temperature sensor for
which the DHW mode was
selected.
Operating conditions:
The DHW pump is activated if:
the DHW system is switched on;
the current time is selected in the schedule;
the temperature of the DHW sensor drops by the value of the hysteresis below
the DHW preset temperature;
the temperature of the feeding sensor will be higher by the "Excess" parameter
than the tank temperature;
the feeding sensor temperature will be higher than the "DHW start
temperature" setting.
The weekly schedule of the DHW pump operation enables switching the zone off for
the selected hours in the selected days of the week.
The thermal cleansing function consists in heating the tank up to the temperature of
70°C. The time for performance of the thermal cleansing is limited to 4 hours.
Maintaining a low DHW temperature (at the level of 40°C) facilitates the development
of bacterial flora in the system. The proper cleansing consists in heating the DHW tank

EUROSTER 12 – INSTALLATION AND OPERATION MANUAL 7
to the temperature of 70°C and flushing the pipes with hot water.
The “Excess” parameter determines the value by which the temperature of the heat
source must exceed the temperature of the tank. Setting a higher temperature
ensures an adequate heating capacity and compensates the heat loss due to the
imperfect insulation of pipes connecting the boiler and the tank. If the temperature of
the heat source is not sufficiently high, then the DHW tank feeding pump is not
switched on.
The overheating alarm is generated if the temperature of the zone sensor exceeds the
value of the "Alarm temperature" setting and is maintained longer than for one
minute.
Switching on of the "Priority" function means that the controller switches off the CH
circuits for the time of DHW heating in order to achieve the temperature preset for the
tank as fast as possible. In the case when the tank cannot be heated up in a
reasonable time, it is possible to limit the DHW priority. The DHW tank is heated for
the time preset by the “Operation time” parameter (Picon active on the display
screen), then the DHW priority is switched off for the “priority break time”. – the
pumps operate simultaneously (Picon flashing on the display). Subsequently, the
priority is switched on again. Only CH and Floor zones implement the “priority”
function.
The "DHW start temperature" parameter determines the threshold of the DHW pump
activation. If the temperature of the feeding sensor exceeds the DHW start
temperature, the pump is activated.
