A window handle, equipped with a posion sensor and a transmier, is an oponal
element of the system. This way the handle provides informaon about the state of the
window. The handle also dierenates between 4 widow posions: opened, closed,
pivoted and trickle venlated (micro-venlaon). The handle transmits informaon to the
RT receiver that controls the relay, e.g. switching o a heater in the event of opening the
window or lowering the temperature down to 3°C to conserve energy. One RT receiver
operates with max 25 handles.

Selecting proper location for AURATON 200 RT
temperature controller
Controller location largely
affects its proper operation.
When located in a place
without air circulation 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 locations 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.
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.
NOTE: We recommend using alkaline batteries to supply AURATON controllers.
Rechargeable baeries should not be used because their rated voltage is too low.

7
Fixing the AURATON 200 RT controller to the wall
Alternative xing methods
To x the AURATON 200 RT 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.

NOTE: When installing an AURATON RT receiver,
make sure that the power supply is switched o.
The receiver should be installed by a professional.
cable e
clamp
mounng plug NOTE: In the permanent system of the building
there must be a switch and an overcurrent pro-
tecon.
NOTE: In order to facilitate installaon, the ter-
minals are ed with extendable clamps. Before
cable connecons are made, they can be discon-
nected from the controllers. The cables may be
routed from the boom of the receiver by bre-
aking out holes in the mounng cover or from
the back of the receiver if the cables are exten-
ded from the wall. In order to connect the cables
from the back, the cover must be broken out.
1. Take off the cover of the front part of the
AURATON 200 RT receiver by unscrewing the
screws half way out.
2. Connect the heang device to the terminals of
the control connecon of the AURATON 200 RT
receiver. Follow the service instrucon of the
heang device. The COM (common) and NO
(normally opened) terminals are used the most
oen.
3. Connect the power supply cables to the ter-
minals of the power supply connecon of the
AURATON RT receiver, in observance of safety
rules.
4. After the cables are connected, they must
be fixed with the “cable fastening holder”
and the covers must be screwed back to the
AURATON 200 RT receiver.

9
Fastening the AURATON 200 RT receiver to a wall
In order to fasten the AURATON 200 RT receiver on a wall:
1. Take off 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.
NOTE: The RT receiver cannot be placed in metal containers (e.g. an assembly box,
a metal enclosure of a heater) in order to not to interfere with its operaon.

10
Pairing of the wireless AURATON 200 RT
controller with the AURATON RT receiver
Unpairing of the controller and the 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.
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 AURATON RT receiver (see „RESET - Unpairing
all devices paired with the AURATON RT receiver”) and then an aempt must be made to
pair the devices again.
NOTE: Only 1 temperature controller may be paired with one receiver.
NOTE: If the wireless controller AURATON 200 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 200 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 AURATON RT receiver waits for pairing for 120 seconds. Aer this period, it auto-
macally returns to normal operaon.
2. On the AURATON 200 RT regulator, press and hold the buons or for
6 seconds unl the transmission symbol ( ) appears on the display. Release the
buon - the regulator transmits the pairing signal for 5 seconds.
3. Successful end of pairing is indicated by the LED diode on the AURATON RT receiver
o longer blinking green, emission of a single sound signal, and the receiver switching
to normal operaon.
1. Unpairing of the AURATON 200 RT controller from the AURATON RT receiver 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.

11
RESET – Deregistering all devices paired
with the RT receiver
Signalling operation and reception
of data packet
In order to deregister all devices paired with the RT receiver, simultaneously press both
the pairing and the deregistering buon ( and ) and hold them for at least 5 seconds
unl the LED ashes alternang red and green. Then release both buons.
A properly completed process of deregistering all devices is signalled aer approx.
2 seconds by the LED colour changing to green and then switching it o for a short period
of me.
Each radio transmission received by the AURATON RT receiver from the paired device is
signalled by a temporary change of LED colour to orange. Switching on the relay is signalled
by the LED lit red, whereas switching it o is signalled by the LED lit green.
In the event of an error during the deregistering process, repeat steps 1 and 2. Should more
errors occur, deregister all paired devices (see “RESET – Deregistering all devices paired
with the RT receiver”) and aempt to pair the device again.
NOTE: If aer execung the RESET funcon the RT receiver is disconnected from power
supply and then connected again, the receiver will automacally enter “pairing”
mode for 120 seconds. A newly purchased RT receiver without any factory-paired
devices (i.e. not the one bundled with the regulator) will behave the same way.
NOTE: When any buon is pressed, a short sound signal is emied.
The AURATON RT receiver waits for unpairing of the device for 120 seconds. Aer this
period, it automacally returns to normal operaon.
2. On the AURATON 200 RT regulator, press and hold the buons or for 6 sec-
onds unl the transmission symbol ( ) appears on the display. Release the buon
– the regulator transmits the pairing signal for 5 seconds.
3. A properly completed deregistering process is signalled by the LED on the AURATON
RT receiver no longer ashing red and the receiver reverng back to normal operaon.

Starting the AURATON 200 RT
controller for the rst time
Temperature setting
FrostGuard function
Aer correct installaon on baeries, the LCD will display, for
a second, all segments (display test) followed by the rmware
version number.
Aer a while, the current temperature in the room will be
displayed. The controller is ready to use.
To set the desired temperature in normal operang mode:
1. Press the or key. The segment displaying 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 key to acknowledge selecon.
AURATON 200 RT 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.

13
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 every-
day 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 mode.

14
Changing hysteresis
Hysteresis prevents the device from switching on too often due to insignificant
temperature uctuaon.
E.g. with HI2 hysteresis and temperature seng of 20°C, the boiler switches on at 19.8°C
and switches o at 20.2°C. With HI4 hysteresis and temperature seng of 20°C, the boiler
switches on at 19,6°C and switches o at 20.4°C.
To change hysteresis, press , and simultaneously
and hold for 3 seconds. When hysteresis change mode is
acve, message HI is displayed.
Use and to change hysteresis sengs.
HI 2 – ±0,2°C (factory seng)
HI 4 – ±0,4°C
HI P – PWM mode (see chapter “PWM mode”).
Press to conrm your selecon.
The controller resumes normal operaon.
With these values determined, the controller switches the heang device on and o
in cycles that enable maintaining temperature as close to the setpoint as possible.
CAUTION: In PWM mode, the controller can switch on the heang device even though
the temperature in the room is higher than preset temperature. This is because the PWM
algorithm tries to maintain the preset temperature and stays ahead of the heang system
behaviour.
Pulse-Width Modulation mode (PWM)
When changing hysteresis sengs, you
can enable PWM mode. In PWM mode,
the controller switches on the heang
device in cycles to minimize temperature
uctuaons. The controller monitors the
temperature rise and drop me.

Cooperation of the AURATON RT receiver with
the AURATON 200 RT regulator and/or
the AURATON T-2 thermometer
The operaon of temperature regulaon in the receiver is based on the binary algorithm
(on/o) using one or two sensor elements.
• The AURATON 200 RT regulator allows for seng and/or monitoring
the temperature.
• The AURATON T-2 thermometer provides informaon about the current temperature
only, without the capability of changing it manually.
A) The manual setpoint – pairing the AURATON 200 RT regulator with the RT receiver
allows for seng the temperature manually and controlling it in the locaon of the
fastening of the 200 RT regulator.
B) The remote setpoint – if the T-2 thermometer is addionally paired with the RT receiver,
the AURATON 200 RT regulator retains the capability of temperature seng, however
its control is performed with the paired T-2 thermometer only. This feature allows for
regulang the temperature in a room other than the one where the AURATON 200 RT
regulator is placed.
An example: you want the temperature in the “children’s room” to be always at 22 °C,
however you do not want children to be able to change it - in that room, you install the
T-2 thermometer, and the AURATON 200 RT regulator in e.g. the kitchen. This way the
temperature in the “children’s room” will always be at 22 °C regardless of temperature
uctuaons in the kitchen.
C) The factory setpoint (20 °C) – if the T-2 thermometer is the only device paired with
the RT receiver, it is not possible to set the temperature manually, and the RT receiver
maintains the factory temperature setpoint of 20 °C.
NOTE!
1. The sequence of pairing the AURATON 200 RT regulator and the T-2 thermometer
is very important. If you want to maintain the remote setpoint, you must rst pair the
AURATON 200 RT with the RT receiver, and then the T-2 thermometer. Reversing the
pairing sequence will cause automac deregistering of the previously paired T-2 ther-
mometer and entering the mode of operaon described in item A.
2. The RT receiver can operate with one AURATON 200 RT regulator and/or one T-2 ther-
mometer only. Pairing a new regulator causes deregistering the previously paired reg-
ulator and the T-2 thermometer. Pairing a new T-2 thermometer causes deregistering
the previously paired T-2 thermometer only.
3. The 200 RT regulator and/or the T-2 thermometer can operate with an unlimited num-
ber of receivers, e.g. one regulator can simultaneously control two independent heang
devices.
4. In the case of the AURATON 200 RT regulator with the T-2 thermometer, the opera-
on indicator on the 200 RT controller’s display does not reect the operaon of the
heang device.

17
Cooperation with the AURATON 200 RT regulator
and/or the AURATON T-2 thermometer as well as
the AURATON H-1 handles
By default, the AURATON RT receiver does not have any AURATON H-1 handle or AURATON
W-1 window posion sensor paired, therefore the relay is controlled by the paired
AURATON 200 RT regulator and/or the AURATON T-2 thermometer. When at least one
H-1 handle is paired with the RT receiver, the relay is controlled in the following manner:
A) The window is closed or trickle-venlated (micro-venlaon).
When the H-1 window handles is paired with the receiver, and all windows are closed or
trickle-venlated, the relay sll maintains the setpoint from the paired AURATON 200 RT
regulator and/or the T-2 thermometer.
B) The window is pivoted.
If at least one window is pivoted, the temperature set in the AURATON 200 RT regulator
is lowered in AURATON RT receiver down to 3 °C. This state will be maintained unl
closing. This state will last unl all windows are closed or trickle-venlated.
C) The window is opened.
When you open a window equipped with the H-1 handle paired for longer than 30 sec-
onds, the relay in the AURATON RT receiver is switched o, as is the connected heang
device. If all the assigned windows are again in a state other than “opened”, the RT
receiver returns to normal cooperaon with the AURATON 200 RT regulator and/or the
T-2 thermometer no earlier than 90 seconds aer switching o the relay. The purpose of
this delay is to prevent too rapid transions of the connected heang devices between
the ON and OFF states. However, if the temperature in the room drops below 7 °C, the
relay inside the receiver is switched on regardless of the posions of windows in order
to prevent the room from freezing..
D) The signal is lost.
When the RT receiver has lost the signal from the H-1 handle paired (3 consecuve
transmissions are lost), it changes the status if this window to “closed”. When the
transmission is restored, the H-1 handle is again properly read o by the RT receiver.

18
Special situations
• When 3 consecuve transmissions (aer 15 minutes) from the AURATON 200 RT
regulator and/or the T-2 thermometer are lost, an error is signalled on the RT receiver
(LED ashing connuously red and green). The RT receiver starts execung the ON - OFF
cycle memorised during the last 24 hours of operaon unl the problem is removed.
• When both signals return (from the AURATON 200 RT regulator and the T-2 thermometer),
the error is cancelled and the receiver enters its normal mode of operaon.
• When only the T-2 thermometer signal returns, the receiver uses the last memorised
setpoint value and maintains it while signalling the error.
• When the H-1 handles, the T-2 thermometer and the AURATON 200 RT regulator (the
temperature is measured with the T-2 thermometer) are paired with the receiver, then
maintaining the work cycle from the last 24 hours occurs only aer losing the signal
from the T-2 thermometer. When only the signal from the AURATON 200 RT is missing,
the RT receiver automacally maintains the last memorised setpoint from the AURATON
2025 RT regulator and also signals an error.
• When you have only the H-1 handles and the T-2 thermometer paired with the RT
receiver without the AURATON 200 RT regulator, the RT receiver maintains a constant,
factory-dened temperature of 20 °C. If you pivot any window equipped with the H-1
handle paired with the receiver, a temperature of 17 °C is maintained. If you open any
window equipped with the H-1 handle paired with the RT receiver, the receiver switches
o the heang device, but will switch it back on when the temperature falls below 7 °C.
Unique features of AURATON 200 RT
• Switching the relay is synchronised with the wave of the 230 V mains voltage in order to
ensure that closing and opening contacts of the relay occurs around the zero-crossing
point. This prevents the occurrence of an electric arc, signicantly extending the relay
service me.
• The AURATON RT receiver is equipped with a unique algorithm for analysing the
ON-OFF cycles. The enre heang cycle from the last 24 hours is recorded in the memory
of the RT receiver. In the event of losing communicaon with the AURATON 200 RT
regulator and/or the T-2 thermometer, the RT receiver automacally executes the
ON-OFF cycle memorised during the last 24 hours. This provides me for restoring
transmission (removing interferences) or xing the 200 RT regulator and/or the T-2
thermometer without a signicant deterioraon of thermal comfort condions in the
controlled spaces.
• Cooperaon with oponal devices (the AURATON T-2 thermometer, the AURATON H-1
window handle).

19
Additional information and notes
• The AURATON 200 RT regulator and/or the T-2 thermometer must be installed at least
1 metre from the RT receiver (too strong a signal from the transmiers can cause
interference).
• At least 30 seconds must elapse between switching the relay o and on.
• Data transmission from the AURATON 200 RT regulator to the receiver occurs upon
each change of 0.2 °C of the surrounding temperature. When the temperature is stable,
the regulator sends heart-beat data every 5 minutes (which is signalled with the LED
blinking orange on the RT receiver).
• In the event of a power outage, the RT receiver will switch o. When power is restored,
the heang device is switched on automacally, and the RT receiver awaits a signal from
the paired transmiers (this signal should be received within 5 minutes of restoring
power). Aer receiving the signal, the RT receiver enters the normal mode of operaon.
• The RT receiver cannot be placed in metal containers (e.g. an assembly box, a metal
enclosure of a heater) in order to not to interfere with its operaon.
• The controller can be switched on or o at any me by holding the key pressed for
a while.
• Pressing any funcon key for the rst me always starts the backlight rst, and then
the key funcon is performed.
• While programming any funcon, if no key is pressed for 10 seconds, this
• will be interpreted as pressing the key.
Cleaning and maintenance
• Clean the outside of the device with a dry cloth. Do not use from solvents
(such as benzene, thinner or alcohol).
• Do not touch the device with wet hands. It may cause electric shock or serious
damage to the device.
• Do not expose the device to excessive smoke or dust.
• Do not touch the screen with a sharp object.
• Avoid contact of the device with liquids or moisture.
