Thank you for purchasing the modern temperature controller based
on an advanced microprocessor.
The Auraton TRA head with the Auraton 200 TRA controller is
a programmable room thermostat.
The Auraton TRA head is intended for installaon on M30x1.5 radiator
inserts and, using a special adapter, on Danfoss RA-N valves (the adapter
is supplied). The Auraton TRA head communicates directly with the
Auraton 200 TRA controller, receiving informaon about the current
temperature in the room and the preset temperature. There can be any
number of radiators with Auraton TRA heads in a room but all must be
paired with the same Auraton 200 TRA controller. If the number of the
Auraton TRA heads is larger, the speed of response of the radiators to
changes of temperature in the room increases, which is very benecial.
FrostGuard funcon
Protects the interior from freezing.
Enables cyclic reducon of set temperature
by 3°C for 6 hours.

Selecting proper location for
temperature controller
Battery installation / replacement
Baery sockets are located inside the controller on both sides of the
display. To install the baeries, remove the controller enclosure as
shown in the gure.
Place two AAA 1.5 V baeries in the baery socket observing the correct
polarity. Then, to improve the operaon, remove the baery cover from
the heads associated with this AURATON 200 TRA for 5 seconds, aer
this me reinstall it back.
NOTE: We recommend using alkaline bateries to supply AURATON
controllers. Rechargeable baeries should not be used because their
rated voltage is too low.
Controller locaon largely aects its proper operaon. When located
in a place without air circulaon or exposed to direct sunlight, the
controller may not control the temperature properly. The controller
should be located on an internal wall of a building (paron wall) in a
place with free air circulaon. Avoid locaons near sources of heat (TV
set, heater, refrigerator) or places exposed to direct sunlight. Locaon
near doors and the resultant vibraon may cause the controller to
funcon improperly.

Fixing the controller to the wall
Alternative xing methods
To x the AURATON 200 TRA controller to the wall:
1. Remove the enclosure (as described on the „Baery installaon/
replacement” secon).
2. Drill 2 holes diameter 6 mm in the wall (use the back of the
controller enclosure to set the right spacing of the holes).
3. Place plasc plugs in the drilled holes.
4. Screw the back of the controller enclosure to the wall with the two
screws provided.
5. Install the baeries and replace the controller enclosure.
NOTE: No expansion bolts are needed for wooden walls. Just drill holes
diameter 2.7 mm (instead of 6 mm) and screw the screws directly into
the wood.
The controller can be mounted to a smooth surface with e.g. two-sided
adhesive tape.
The controller can also be placed in any locaon on an even surface on a
support at the back of the enclosure.

temperature will switch to edit mode and start
blinking.
2. With the and keys, set the desired temperature with
the accuracy of up to 0.2°C.
3. Press the <ok key to acknowledge selecon.
AURATON 200 TRA controller features the special FrostGuard funcon
to protect the room from possible freezing. The funcon is acvated
when the controller is switched o.
With the controller switched o, when the room temperature drops
to 2°C, the Fr ( ) symbols will appear and signal will be sent to the
receiver to start heang. When the temperature raises to 2.2°C, the
display will turn o again and signal will be sent to the receiver to turn
the heang o.
NOTE: When pressing any funcon key for the rst me, the backlight
is turned on and then the key funcon is acvated.

Setting the temporary
temperature decrease mode
Switching off the temporary
temperature decrease
If, for some reasons, you would like to decrease temperature
in the room, everyday and at the same me, by 3°C,
temporary reducon for 6 hours is possible. To do so:
1. Press and hold for 3 seconds both keys.
The moon symbol will be displayed ( ) .
2. The controller is switched to the temporary temperature decrease
mode and everyday at the same me will decrease the set
temperature in a normal mode by 3°C for 6 hours.
NOTE: Aer 6 hours, the controller will return to the main
temperature seng. Instead of the moon symbol ( ) the sun ( )
symbol will be displayed.
NOTE: The temporary temperature decrease mode always starts
when the funcon is turned on. This means that the possible temporary
temperature decrease has to be set at the me you want it to take
place.
Press and hold the keys again to switch o the temporary
temperature decrease mode.
The moon ( ) or sun ( ) symbol will disappear and only the room
temperature will be displayed. The controller returns to the normal
operang.

Method of installation of the TRA head
on a radiator with an M30x1.5 insert
In order to install the Auraton TRA head on a radiator with the most
common insert in the market, i.e. M30x1.5, the following acons must
be performed:
a) Screw the reducon ng A
onto the insert delivered with the
head (all the way).
b) Take o the head baery cover
using a at screwdriver.
c) Install two AAA baeries in the
head, paying aenon to their
polarity. The pin of the head moves
to the fully open posion, which
is necessary for installaon of the
head on the reducon ng.
d) Slide the safety ring into the
“released” posion.
e) Slide the head all the way onto the
reducing ng A.

11
b) Tighten all the way the
reducon ng A on the
installed reducon ng B.
a) Put on the two halves of
the reducon ng B onto
the Danfoss RA-N insert.
f) Turn the safety ring into
the “secured” posion.
g) Pair the head with the
Auraton 200 TRA, unless pairing
has been done earlier.
h) Close the head baery cover.
Installation on the head with
a Danfoss RA-N insert
In order to install the Auraton TRA head
on a radiator with a Danfoss RA-N insert,
perform the following procedure:
c) Perform steps b) through h) in the chapter tled “Method of
installaon of the TRA head on a radiator with an M30x1.5 insert.”

12
Pairing of the Auraton TRA head
with the Auraton 200 TRA controller
Proper operaon of the Auraton TRA head requires pairing it with the
Auraton 200 TRA controller. The pairing process is the following:
1. Reset the Auraton TRA head to the default sengs (see the chapter
“Reseng the Auraton TRA head to the default sengs”).
2. In the Auraton 200 TRA controller simultaneously press the buons
<ad> + <ok>for more than 3 [s].
3. Aer 3 [s], the Auraton 200 TRA controller sends pairing data to the
Auraton TRA head, which the head indicates with three beeps.
4. Aer successful pairing of the Auraton 200 TRA with the head, close
the baery cover (if installed on the radiator).
Resetting the Auraton TRA head to the
default settings
a) take o the head baery cover
b) take out the baery (one of the two or both)
c) press the baery cover closing buon (it is located on the electronics
board between the baeries)
d) install the baeries while holding the buon pressed
e) aer you hear three beeps, release the buon

13
Communication between the head
and the Auraton 200 TRA controller and
error signals
In order to save the baery, the Auraton 200 TRA controller
communicates with the head every 2 minutes. Immediately aer the
Auraton 200 TRA controller logs into the head, the two devices are
synchronized; the process takes about one minute. The synchronizaon
process is not indicated in any way but is necessary for proper operaon
of the set.
Communicaon may be disturbed if the Auraton 200 TRA is reset (for
example in order to replace the baery). The head indicates interrupted
communicaon aer 6 minutes with a LED diode blinking every 8 [s].
Aer a maximum of 4 hours, the head should automacally synchronize
itself with the Auraton 200 TRA controller. This me can be reduced to
2 minutes if, aer the reset of the Auraton 200 TRA controller, the tab is
taken o from the head and reinstalled aer 3 [s].
Even aer communicaon between the head and the
Auraton 200 TRA controller is interrupted, the user should not
experience any deteriorated adjustment of temperature. In such a case,
the head stabilizes the temperature of the radiator on the level that was
required earlier in order to maintain the temperature in the room.
Signaling after startup of the head
Aer the baery is inserted, the head indicates that it is ready for
operaon by way of sound signals and a LED diode. There are two
possible scenarios:
a) a single beep - it means that an Auraton 200 TRA controller has
been paired with the head. In such a case, the head only has to be
installed on the radiator insert and the baery cover must be closed.
Aer about 30 [s], the head starts adjusng the temperature.
b) three beeps - an Auraton 200 TRA controller has not been paired
with the head. Aer the baery cover is closed, the head DOES NOT
perform the temperature adjustment algorithm.
If the head press pin is not in the fully opened posion, the motor starts
and the actuator moves away from the radiator.

Installation tips
Battery operation time and discharged
battery indication
Auraton 200 TRA should be places in the same room with the head
and the radiator. It should not be placed near the radiator, on doors,
or in places exposed to sunlight. The head, on the other hand, should
be installed on the radiator insert not more than 20 cm away from the
radiator. In nearly all cases this requirement is met because radiator
manufacturers integrate inserts with radiators. If the head is located
away from the radiator (the radiator does not heat the head directly),
adjustment of temperature is less dynamic. As a result, temperature
uctuaons in the room may be larger. On the other hand, the
Auraton TRA head may be installed on inserts located at the boom of
the radiator (e.g. in the case popular ladder type bathroom radiators).
The declared me of operaon with one set of AAA alkaline baeries is
one year. Discharged baeries do not aect adjustment of temperature.
The head indicates low baery status by blinking the LED twice every 8
[s]. Also, when the baery becomes even more discharged, the head
starts eming two beeps every 8 minutes. In order to switch o the
beeping for 1 day, press any key on the Auraton 200 TRA controlled
paired with the head or li the head ap for 2 [s] and reinstall it.
Calibration error signals
Aer the head is installed on the radiator and the baery cover is
closed, the head performs calibraon of the mechanical system. If an
error occurs during calibraon, it is indicated with the buzzer sounding
for 1 [s] every 1 [s]. If a calibraon error occurs, the following must be
checked:
a) Is the reducon ng A properly screwed to the radiator insert?
b) Is the reducon ng B (in the case of Danfoss inserts) properly
fastened on the insert and is the reducon ng A properly screwed
into the reducon ng B?
c) Is the safety ring properly set in the “secured” posion?
d) Are the installed baeries not discharged (see the chapter “Method
of installaon of the TRA head on a radiator with an M30x1.5 insert”
items b) and c)).
