Wireless central heang pump controller
AURATON S03 RT
The AURATON S03 RT controller is tended for wireless control of a central
heang (CH) pump.
Before you start using the controller, please read this instrucon carefully.

APPLICATION
AURATON S03 RT is intended for automacally switching on and o circula-
on pumps depending on the temperature. The controller-pump assembly
forces the water to circulate in the central heang system with a coal-red
boiler or a gas boiler. The controller’s sensor measures the temperature of the
water on the supply side of the CH system. In a CH system with a coal-red
boiler, the controller switches o the circulaon pump aer the ame in the
boiler is exnguished. Pumping of water is not recommended when the ame
is exnguished because the air dra into the chimney causes faster cooling of
the water in the boiler faster than in the radiators. The opmum temperature
can be set on the controller’s scale (most oen 40 °C).
In a CH system with a gas boiler, the temperature set on the controller must
be lower than the temperature set on the CH boiler. If the temperature is set
on the controller above the dew point, it prevents condensaon in the boiler
during the heang of the water in the CH system.
AntyStop system
The AntyStop (AS) system installed in the Auraton S03 RT controller prevents
seizure of the rotor of an unused pump. Also, a built in processor starts the
pump every 14 days for 30 seconds aer the heang season is over. In order
for the system to work aer the heang season, the controller must be
switched on with the AS funcon acve at all mes.

Mounting the controller on a wall
In order to mount the controller on a wall:
1. Take o the enclosure of the controller.
2. Drill two 6 mm diameter holes in the wall.
3. Put two wall plugs in the drilled holes.
4. Fasten the back part of the enclosure to the wall
using the screws provided with the set.
5. Put on the controller’s enclosure.
If the wall is made of wood, there is no need to use wall plugs. Only 2.7 mm
diameter holes (instead of 6 mm) should be drilled and the screws should be
driven directly into the wood.

External temperature
sensor
External
temperature sensor Terminal block
As a standard, aer the baery is put in, the controller without a sensor
connected displays the temperature from the internal temperature sensor.
When the external temperature sensor is connected, the controller automat-
ically reads the values measured by that sensor.
If the external sensor is disconnected or defecve, the control-
ler switches into the emergency mode (dashes are shown as
the temperature value) which results in switching on the relay
and, consequently, the controlled device. In order to leave the
emergency mode, the external temperature sensor must be reconnected or the
controller must be restarted by simultaneously pressing and holding the
and switches for at least 5 seconds. Aer this procedure is completed, the
controller displays the temperature measured by the internal sensor.
Mounting the sensor
Install the sensor on an uncovered outlet pipe connected to the CH boiler
(as close to the boiler as possible). Press the sensor against the tube using
a clamp. It is recommended to wrap the boiler pipe from the boiler to the
sensor with an insulaon material.
If a coal-red boiler and a gas-red boiler work in the same CH system,
the sensor should be installed in a locaon where the two outlets merge
and must be insulated.

Installation of the receiver
CAUTION! The cables delivered in a set together with the controller
are suitable for maximum loads equal to 2.5 A.
If devices with higher power are connected, the cables should be
replaced with ones of appropriate cross-secons.
NOTE: When installing an AURATON RT receiver, make sure that the power
supply is switched o. The receiver should be installed by a profes-
sional.
NOTE: In the permanent system of the building there must be a switch and
an overcurrent protecon.
NOTE: In order to facilitate installaon, the terminals are ed with ex-
tendable clamps. Before cable connecons are made, they can be
disconnected from the controllers. The cables may be routed from
the boom of the receiver by breaking out holes in the mounng
cover or from the back of the receiver if the cables are extended from
the wall. In order to connect the cables from the back, the cover must
be broken out.

Fastening the AURATON RT receiver to a wall
In order to fasten the AURATON RT receiver on a wall:
1. Take o the covers from the front part of the controller
(see chapter “Installaon of the AURATON RT receiver).
2. Mark the locaon of the holes for the fastening screws on
the wall.
3. In the marked locaons, drill holes with diameters appropriate for the
diameters of the enclosed wall plugs (5 mm).
4. Put the wall plugs in the drilled holes.
5. Fasten the AURATON RT receiver to the wall using screws so that the
receiver is well fastened.
Note: If the wall is wooden, there is no need to use wall plugs.
In such a case, drill two holes 2.7 mm in diameter instead
of 5 mm, and screw the screws directly into the wood.

Pairing of the wireless AURATON S03 RT
controller with the AURATON RT receiver
Aer the receiver is connected to the network, the receiver must be switched
on by quickly pressing the power buon ( ). If the device is switched on,
the green power supply diode becomes illuminated and a single sound signal
is emied. In order to switch o the receiver, e.g. outside of the heang
season, press the power buon and hold it for 3 seconds unl a double
sound signal is audible and the green power supply diode is switched o and,
consequently, the heang device is switched o.
NOTE: If the wireless controller AURATON S03 RT is sold together with the
AURATON RT receiver, the two devices are factory-paired. Devices
purchased separately must be paired.
1. Pairing of the AURATON S03 RT controller with the AURATON RT receiver
is iniated by pressing the right pairing buon ( ) – a single sound signal
is emied – on the AURATON RT receiver and by holding it pressed for at
least 3 s unl the LED diode starts blinking with green light (double sound
signal) – then the buon must be released.
The receiver waits for pairing for 120 seconds. Aer this period, it auto-
macally returns to normal operaon.
2. On the receiver, press the buon for 5 seconds unl the transmis-
sion ( ) symbol on the display is illuminated. Release the buon – the
controller emits the pairing signal for 5 seconds.
3. Successful end of pairing is indicated by the LED diode on the receiver
no longer blinking green and the receiver switching to normal operaon.

15
In the event of a pairing error, steps 1 and 2 must be repeated. If more
errors occur, all devices must be unpaired by RESETTING the receiver
(see “RESET - Unpairing all devices paired with the receiver”) and then an
aempt must be made to pair the devices again.
NOTE: Only 1 controller may be assigned to one receiver.
Signaling of operation and receipt
of data packets
Each recepon of radio transmission from a paired device is indicated by
the AURATON RT receiver by a momentary change of the color of the LED
diodes. Aer the relay becomes acvated, the LED diode is red and aer it
is switched o – it is green.
NOTE: When any buon is pressed, a short sound signal is emied.
Unpairing of the controller and the RT receiver
1. Unpairing of the AURATON S03 RT controller from the AURATON RT re-
ceiver is iniated by pressing the le unpairing buon ( ) on the receiver
and holding it for at least 3 seconds unl the LED diode starts blinking
red – then the buon must be released. The sound signal works in the
same way as during pairing, i.e. when a buon is pressed, a short sound
is emied and another short sound signal aer 3 seconds.
The receiver waits for unpairing of the device for 120 seconds. Aer this
period, it automacally returns to normal operaon.

16
2. On the receiver, press the buon for 5 seconds unl the trans-
mission ( ) symbol on the display is illuminated. Release the buon.
3. Successful compleon of unpairing is indicated by the LED diode no longer
blinking red and the repeater switching to normal operaon.
In the event of an unpairing error, steps 1 and 2 must be repeated. If more
errors occur, all devices must be unpaired (see “RESET – Unpairing all
devices paired with the receiver”).
RESET – Unpairing all devices paired with
the AURATON RT receiver
In order to unpair all devices paired with the AURATON RT receiver, simul-
taneously press and hold both the pairing and the unpairing buon ( and
) for at least 5 seconds, unl the LED diode starts blinking green and red
alternately. Then release both buons. Sound signal: when the buon is
pressed, a short sound signal is emied, followed by another short signal
5 seconds later.
Successful compleon of unpairing of all devices is signalized aer about
2 seconds by the diode color changing to green and then switching o for
a short me.
NOTE: If the power supply of the AURATON RT receiver is switched o and
then switched on aer the RESET, the receiver automacally goes into
the “pairing” mode for 120 seconds. A newly purchased (separately
from the controller) AURATON RT receiver acts in the same way if it
has no factory-paired devices.

17
Switching the controller on for the rst time
Aer the baeries are properly installed in
the baery compartment, the LCD display
shows all segments for one second (a dis-
play test) and then it shows the soware
version.
Aer a moment, the current temperature
in the room is displayed. Then the control-
ler is ready for operaon.
Temperature setting
NOTE: The first time any function button is pressed, the illumination
is always switched on first and only then the button’s function
is acvated.
In order to set the temperature in the nor-
mal operaon mode:
1. Press the or buon. The
segment that shows the temperature
goes into the edion mode and starts
blinking.

18
2. Use the and buons to set the desired temperature in the
room with the accuracy of 1 °C.
3. Conrm the selecon by briey pressing the buon.
Setting the “reduction of the programmed
pump shutdown temperature”
The controller has the funconality of reducon of the pump
shutdown temperature. When the seng is e.g. 40 °C and the
reducon is set to 1 °C, the pump shuts down at the tempera-
ture of 39 °C. If the reducon is set to 5 °C,
the pump shuts down at 35 °C.
In order to set the reducon temperature,
press the buon (the factory seng
is 3 °C).
Each me the buon is pressed, the tem-
perature seng changes by 1 °C in a loop
from 1 °C to 5 °C.
Conrm the selecon by pressing the buon.
NOTE: If the buon is not press, the controller returns to the normal
operaon mode aer 10 seconds.

19
Switching the “AntyStop” mode on/off
In order to switch the AntyStop mode on, press
and hold the buon pressed for 3 seconds.
The display shows (the funcon is acve).
The AntyStop mode prevents seizing of the rotor of an unused pump. Also,
a built in processor starts the pump every 14 days for 30 seconds after
the heang season is over. In order for the system to work aer the heat-
ing season, the controller must remain switched on with the AntyStop
funcon acve.
Comments:
• The controller may be switched on or o at any me by briey pressing
the buon.
• The rst me any funcon buon is pressed, the illuminaon is always
switched on rst and only then the buon’s funcon is acvated.
• When programming any funcon, if no buons are pressed for 10 seconds,
this is equivalent to pressing the buon.

20
Additional functions
• Aer baeries are installed, the controller displays the temperature from
the external temperature sensor.
• When the external sensor is connected (the terminal block is located
under the enclosure), the controller automacally takes the readings
from that sensor.
• If the external sensor is disconnected or defecve, the controller goes into
the emergency mode (dashes are shown as the measured temperature),
which results in the CH pump shung down unl the defect is eliminated.
This is intended to protect the heang system from overheang. In order
to leave the emergency mode, connect the external temperature sensor
back or reset the controller by taking out the baery unl the display
switches o. Aer this procedure is completed, the controller displays
the temperature measured by the internal sensor.
