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 (partition wall) in a place with free air circulation. Avoid locations near sources of heat (TV set, heater, refrigerator) or places exposed to direct sunlight. Location near doors and the resultant vibration may cause the controller to function improperly.

Battery installation/replacement

Battery sockets are located inside the controller on both sides of the display. To install the batteries, remove the controller enclosure as shown in the figure.

Place two AAA 1.5 V batteries in the battery socket observing the correct polarity.

Fixing the AURATON 200 RT controller to the wall

To fix the AURATON 200 RT controller to the wall:

1. Remove the enclosure (as described on the “Battery installation/replacement” section).
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 plastic plugs in the drilled holes.
4. Screw the back of the controller enclosure to the wall with the two screws provided.
5. Install the batteries and replace the controller enclosure.

1. hole for a mounting screw

Alternative fixing methods

The controller can be mounted to a smooth surface with e.g. two-sided adhesive tape. The controller can also be placed in any location on an even surface on a support at the back of the enclosure.

Installation of the AURATON RT receiver

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 “Installation of the AURATON RT receiver”).
2. Mark the location of the holes for the fastening screws on the wall.
3. In the marked locations, 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.

Pairing of the wireless AURATON 200 RT controller with the AURATON RT receiver

After the receiver is connected to the network, the receiver must be switched on by quickly pressing the power button (F). If the device is switched on, the green power supply diode becomes illuminated and a single sound signal is emitted. In order to switch off the receiver, e.g. outside of the heating season, press the power button and hold it for 3 seconds until a double sound signal is audible and the green power supply diode is switched off and, consequently, the heating device is switched off.

1. Pairing of the AURATON 200 RT controller with the AURATON RT receiver is initiated by pressing the right pairing button (D) a single sound signal is emitted – on the AURATON RT receiver and by holding it pressed for at least 3 s until the LED diode starts blinking with green light (double sound signal) – then the button must be released.
   The AURATON RT receiver waits for pairing for 120 seconds. After this period, it automatically returns to normal operation.
2. On the AURATON 200 RT regulator, press and hold the buttons b d or c d for 6 seconds until the transmission symbol ( W ) appears on the display. Release the button – 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 operation.

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 attempt must be made to pair the devices again.

Unpairing of the controller and the RT receiver

1. Unpairing of the AURATON 200 RT controller from the AURATON RT receiver is initiated by pressing the left unpairing button (E) on the receiver and holding it for at least 3 seconds until the LED diode starts blinking red – then the button must be released. The sound signal works in the same way as during pairing, i.e. when a button is pressed, a short sound is emitted and another short sound signal after 3 seconds.
   The AURATON RT receiver waits for unpairing of the device for 120 seconds. After this period, it automatically returns to normal operation.
2. On the AURATON 200 RT regulator, press and hold the buttons b d or c d for 6 seconds until the transmission symbol ( W ) appears on the display. Release the button – 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 flashing red and the receiver reverting back to normal operation.

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 attempt to pair the device again.

RESET – Deregistering all devices paired with the RT receiver

In order to deregister all devices paired with the RT receiver, simultaneously press both the pairing and the deregistering button (D E) and hold them for at least 5 seconds until the LED flashes alternating red and green. Then release both buttons.

A properly completed process of deregistering all devices is signalled after approx. 2 seconds by the LED colour changing to green and then switching it off for a short period of time.

Signalling operation and reception of data packet

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 off is signalled by the LED lit green.

Starting the AURATON 200 RT controller for the first time

Temperature setting

FrostGuard function

AURATON 200 RT controller features the special FrostGuard function to protect the room from possible freezing. The function is activated when the controller is switched off.

With the controller switched off, when the room temperature drops to 2°C, the Fr (!) symbols will appear and signal will be sent to the receiver to start heating. When the temperature raises to 2.2°C, the display will turn off again and signal will be sent to the receiver to turn the heating off.

Setting the temporary temperature decrease mode

If, for some reasons, you would like to decrease temperature in the room, everyday and at the same time, by 3°C, temporary reduction for 6 hours is possible. To do so:

1. Press and hold for 3 seconds both b c keys. The moon symbol will be displayed (T).
2. The controller is switched to the temporary temperature decrease mode and everyday at the same time will decrease the set temperature in a normal mode by 3°C for 6 hours.

Switching off the temporary temperature decrease

Press and hold the b c keys again to switch off the temporary temperature decrease mode. The moon (T) or sun (S) ymbol will disappear and only the room temperature will be displayed. The controller returns to the normal operating mode.

Changing hysteresis

Hysteresis prevents the device from switching on too often due to insignificant temperature fluctuation.
E.g. with HI 2 hysteresis and temperature setting of 20°C, the boiler switches on at 19.8°C and switches off at 20.2°C. With HI 4 hysteresis and temperature setting of 20°C, the boiler switches on at 19,6°C and switches off at 20.4°C.

Pulse-Width Modulation mode

(PWM)

When changing hysteresis settings, you can enable PWM mode. In PWM mode, the controller switches on the heating device in cycles to minimize temperature fluctuations. The controller monitors the temperature rise and drop time.
With these values determined, the controller switches the heating device on and off in cycles that enable maintaining temperature as close to the setpoint as possible.

Cooperation of the RT receiver with a heating device

AURATON RT simplified connection diagram with heating device

Cooperation of the AURATON RT receiver with the AURATON 200 RT regulator and/or the AURATON T-2 thermometer

The operation of temperature regulation in the receiver is based on the binary algorithm (on/off) using one or two sensor elements.

• The AURATON 200 RT regulator allows for setting and/or monitoring the temperature.
• The AURATON T-2 thermometer provides information about the current temperature only, without the capability of changing it manually.

1. The manual setpoint – pairing the AURATON 200 RT regulator with the RT receiver allows for setting the temperature manually and controlling it in the location of the fastening of the 200 RT regulator.
2. The remote setpoint – if the T-2 thermometer is additionally paired with the RT receiver, the AURATON 200 RT regulator retains the capability of temperature setting, however its control is performed with the paired T-2 thermometer only. This feature allows for regulating 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 fluctuations in the kitchen.
3. 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.

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 position 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:

1. The window is closed or trickle-ventilated (micro-ventilation).
   When the H-1 window handles is paired with the receiver, and all windows are closed or trickle-ventilated, the relay still maintains the setpoint from the paired AURATON 200 RT regulator and/or the T-2 thermometer.
2. 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 until closing. This state will last until all windows are closed or trickle-ventilated.
3. The window is opened.
   When you open a window equipped with the H-1 handle paired for longer than 30 seconds, the relay in the AURATON RT receiver is switched off, as is the connected heating device. If all the assigned windows are again in a state other than “opened”, the RT receiver returns to normal cooperation with the AURATON 200 RT regulator and/or the T-2 thermometer no earlier than 90 seconds after switching off the relay. The purpose of this delay is to prevent too rapid transitions of the connected heating 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 positions of windows in order to prevent the room from freezing.
4. The signal is lost.
   When the RT receiver has lost the signal from the H-1 handle paired (3 consecutive 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 off by the RT receiver.

Special situations

• When 3 consecutive transmissions (after 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 flashing continuously red and green). The RT receiver starts executing the ON – OFF cycle memorised during the last 24 hours of operation until 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 operation.
• 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 after losing the signal from the T-2 thermometer. When only the signal from the AURATON 200 RT is missing, the RT receiver automatically 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-defined 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 off the heating 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, significantly extending the relay service time.
• The AURATON RT receiver is equipped with a unique algorithm for analysing the ON-OFF cycles. The entire heating cycle from the last 24 hours is recorded in the memory of the RT receiver. In the event of losing communication with the AURATON 200 RT regulator and/or the T-2 thermometer, the RT receiver automatically executes the ON-OFF cycle memorised during the last 24 hours. This provides time for restoring transmission (removing interferences) or fixing the 200 RT regulator and/or the T-2 thermometer without a significant deterioration of thermal comfort conditions in the controlled spaces.
• Cooperation with optional devices (the AURATON T-2 thermometer, the AURATON H-1 window handle).

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 transmitters can cause interference).
• At least 30 seconds must elapse between switching the relay off 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 off. When power is restored, the heating device is switched on automatically, and the RT receiver awaits a signal from the paired transmitters (this signal should be received within 5 minutes of restoring power). After receiving the signal, the RT receiver enters the normal mode of operation.
• 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 operation.
• The controller can be switched on or off at any time by holding the d key pressed for a while.
• Pressing any function key for the first time always starts the backlight first, and then the key function is performed.
• While programming any function, if no key is pressed for 10 seconds, this will be interpreted as pressing theu d 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.
