Choosing the right location for your temperature controller

The proper operation of the thermostat is largely influenced by its location. Siting it in a location without air circulation or in direct sunlight will result in incorrect temperature control. To ensure proper operation, the thermostat should be mounted on an interior wall (partition wall). Choose a location where you spend most of your time, with free air circulation. Avoid proximity to heat-emitting devices (television, radiator, refrigerator) or locations exposed to direct sunlight. Avoid placing the thermostat directly next to a door to avoid vibration.

Battery installation/replacement

The battery compartments are located inside the controller on both sides of the display. To install the batteries, remove the controller housing as shown in the illustration.

Insert two 1.5V AAA batteries into the battery compartment, paying attention to the correct polarity of the batteries.

Mounting the AURATON 200 RT temperature controller to the wall

To attach the AURATON 200 RT to the wall:

1. Remove the controller housing (as shown in the "Installation/Replacing the Battery" section).
2. Drill two 6 mm diameter holes in the wall (mark the hole spacing using the rear part of the controller housing).
3. Insert the expansion bolts into the drilled holes.
4. Screw the rear part of the controller housing to the wall using the screws included in the kit.
5. Install the batteries and put the regulator housing back on.

1. Hole for mounting screw.

Alternative mounting methods

The controller can be attached to a smooth surface using double-sided tape, for example. The controller can also be placed anywhere on a flat surface using the stand located on the rear of the housing.

How to mount the RT receiver

Mounting the RT receiver to the wall

To attach the AURATON RT receiver to the wall:

1. Remove the cover from the front of the controller (see the section "How to mount the RT receiver") .
2. Mark the position of the mounting screw holes on the wall.
3. In the marked places, drill holes with the diameter of the dowels included in the kit (5 mm).
4. Insert expansion bolts into the drilled holes.
5. Screw the RT receiver to the wall with screws so that they hold the receiver securely.

Pairing the Auraton 200 RT wireless controller with the Auraton RT receiver

After connecting to the mains, turn on the receiver by briefly pressing the power button ( F ). When the device is turned on, the green power LED will light up and you will hear a single beep. To turn off the receiver, e.g., outside the heating season, hold the power button for 3 seconds until you hear a double beep and the green power LED turns off, turning off the heating device.

1. Pairing the 200 RT controller with the RT receiver is initiated by pressing the right pairing button ( D ) on the RT receiver – a single beep – and holding it for at least 3 seconds until the LED starts flashing green (double beep), then releasing the button.
   The AURATON RT receiver waits 120 seconds for pairing. After this time, it will automatically return to normal operation.
2. On the AURATON 200 RT controller, press the b d or c d for 6 seconds until the transmission symbol ( W ) lights up on the display.
3. Successful completion of the pairing is indicated by the LED on the AURATON&RT receiver stopping flashing green, by a single sound signal and by the receiver switching to normal operation.

If an error occurs during pairing, repeat steps 1 and 2. If further errors occur, deregister all devices by RESETting the RT receiver (see "RESET – Deregistering all devices assigned to the RT receiver") and try pairing the devices again.

Deregistering the controller from the RT receiver

1. To deregister the 200 RT controller from the RT receiver, press the left deregistration button ( E ) on the receiver for at least 3 seconds until the LED flashes red, then release the button. The sound signal works in the same way as pairing, i.e., pressing the button is signaled by a short beep, followed by a double short beep after 3 seconds.
   The AURATON RT receiver waits 120 seconds for the device to be deregistered. After this time, it will automatically return to normal operation.
2. On the AURATON 200 RT controller, press the b d or c d for 6 seconds until the transmission symbol ( W ) lights up on the display.
3. Successful completion of deregistration is indicated by the LED on the AURATON RT receiver stopping flashing red, by a single sound signal and by the receiver switching to normal operation.

If an error occurs during deregistration, repeat steps 1 and 2. If further errors occur, deregister all paired devices (see "RESET – Deregistering all devices assigned to the RT receiver").

RESET – Unchecking all devices assigned to the RT receiver

To deregister all paired devices in the RT receiver, simultaneously press and hold both pairing and deregister buttons ( D E ) for at least 5 seconds until the LED indicator changes to alternating green and red flashing. Then release both buttons. Audible signal: pressing the button – a short beep – after 5 seconds – a double short beep.

Successful deregistration of all devices is indicated after approximately 2 seconds by the indicator changing to green and then briefly fading out.

Signaling of operation and receipt of data packets

Each time a radio transmission from a paired device is received, the AURATON RT receiver signals this with a momentary alternating color change of the LEDs. When the relay is on, the LED is red; when the relay is off, the LED is green.

First start-up of the regulator

Temperature setting

FrostGuard function

AURATON 200 RT thermostat is equipped with a special "FrostGuard" function that protects the room from freezing. This function activates when the thermostat is turned off .

When the controller is off and the room temperature drops to 2°C, the symbols Fr (!) and a signal will be sent to the receiver, which will turn on the heating. When the temperature rises to 2.2°C, the display will turn off again and a signal will be sent to the receiver, which will turn off the heating.

Setting the "temporary temperature reduction" mode

If, for various reasons, you'd like to lower the room temperature by 3°C at the same time each day, you can temporarily reduce it for 6 hours. To do this, follow these steps:

1. b and c buttons for 3 seconds T ) will appear on the display
2. The controller switches to the "temporary temperature reduction" mode and every day at the same time it will lower the temperature programmed in the normal mode by 3°C for a period of 6 hours.

Turning off the "temporary temperature reduction" mode

To deactivate the "temporary temperature reduction" mode, press and hold the buttons again for 3 seconds. b cThe moon symbol on the display will go out (T) or sun (S) and only the room temperature will remain displayed. The controller has returned to normal operating mode.

Hysteresis change

Hysteresis is designed to prevent the actuator from switching on too frequently due to minor temperature fluctuations.
For example, for HI 2 HI 4 hysteresis, with the temperature set to 20°C, the boiler will turn on at 19.6°C and turn off at 20.4°C.

PWM operating mode

(Pulse-Width Modulation)

By changing the hysteresis settings (see the "Configuration Settings" section), you can enable PWM operation.
In this mode, the controller periodically turns on the heating device to minimize temperature fluctuations. The controller checks the temperature rise and fall times.
Knowing these values, the controller turns the heating device on and off in cycles to maintain the temperature as close to the setpoint as possible.

Operation of the RT receiver with a heating device

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

The operation of the temperature control in the receiver is based on a two-state algorithm (on/off) using one or two sensor elements.

• The AURATON 200 RT controller allows you to set the temperature and/or control it continuously.
• The AURATON T-2 thermometer only provides information about the current temperature without the possibility of changing it manually.

1. Manual setting – by pairing the AURATON 200 RT regulator with the RT receiver, we can manually set the temperature and control it at the location where the 200 RT regulator is mounted.
2. Remote setting – if you pair a T-2 thermometer with the same RT receiver, the AURATON 200 RT regulator will retain its temperature setting capability, but control will only be performed by the paired T-2 thermometer. This allows you to control the temperature in a room other than the one where the
   AURATON 200 RT regulator is located.
   For example: If you want the "children's room" to always be at 22°C, but you don't want the children to be able to change the temperature, you can install the T-2 thermometer in that room and the AURATON 200 RT regulator, for example, in the kitchen. This solution ensures the "children's room" will always be at 22°C, regardless of temperature fluctuations in the kitchen.
3. Factory setting (20°C) – if only the T-2 thermometer is paired with the RT receiver, it will not be possible to manually set the temperature and the RT receiver will maintain the factory temperature setting of 20°C.

Cooperation with the AURATON 200 RT regulator and/or the AURATONT-2 thermometer and the AURATON H-1 door handles

By default, the AURATON RT receiver does not have any AURATON H-1 handle paired, so the relay is controlled by the paired AURATON 200 RT regulator and/or AURATON T-2 thermometer. When at least one H-1 handle is paired with the RT receiver, the relay will be controlled as follows:

1. Window closed or unsealed (micro-ventilation)
   When we associate H-1 handles with the receiver and all windows are closed or unsealed, the relay still implements the setting from the associated AURATON 200 RT regulator and/or T-2 thermometer.
2. Window tilted
   When even one window is tilted, the AURATON RT receiver will lower the set temperature of the AURATON 200 RT regulator by 3°C. This will last until all windows assigned to the RT receiver are closed or unsealed. Example: The AURATON 200 RT regulator is set to an actual temperature of 21°C. Then we tilt the window with the associated H-1 handle. The RT receiver will maintain a room temperature of 18°C .
3. Window Open:
   When a window with an associated H-1 handle is opened for longer than 30 seconds, the relay in the AURATON RT receiver will be deactivated, and the heating device will also be turned off. If all assigned windows are again in a state other than open, the RT receiver will return to normal operation with the AURATON 200 RT regulator and/or T-2 thermometer no sooner than 90 seconds after the relay is turned off. This is an intentional delay to prevent excessively abrupt on-off transitions of the heating devices. However, if the room temperature were to drop below 7°C, regardless of the window position, the relay in the receiver will activate, turning on the heating device to prevent the room from freezing.
4. Signal Loss
   When the RT receiver loses the signal from the associated H-1 handle (3 consecutive lost transmissions), it changes the status of this window to closed. Once transmission is restored, the H-1 handle is again correctly read 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, a failure will be signalled on the RT receiver (the LED will continuously flash alternately in red and green). Until the problem is eliminated, the RT receiver will switch to the memorised on/off cycle from the last 24 hours.
• When both signals return (from the AURATON 200 RT regulator and the T-2 thermometer), the error is cleared and the receiver switches to normal operation.
• When the T-2 thermometer signal returns, the receiver uses the last saved setting and maintains it, continuing to signal the failure.
• When the H-1 handles, T-2 thermometer, and AURATON 200 RT regulator are paired with the receiver (temperature is measured by the T-2 thermometer), the operating cycle from the last 24 hours will be maintained only after the signal from the T-2 thermometer is lost. When only the signal from the AURATON 200 RT regulator is lost, the RT receiver automatically maintains the last saved setting of the AURATON 200 RT regulator, but also signals a failure.
• When only the H-1 handles and the T-2 thermometer are paired with the RT receiver without the AURATON 200 RT regulator, the RT receiver will maintain a constant factory-set temperature of 20°C. If you tilt any window with the paired H-1 handle, the temperature will be maintained at 17°C. If you open any window with the paired H-1 handle, the RT receiver will turn off the heating device, but will turn it back on if the temperature drops below 7°C.

Unique features of AURATON 200 RT

• The relay's switching is synchronized with the 230V mains supply voltage so that the relay's armature contacts always close and open at the zero crossing of the mains voltage. This prevents arcing and significantly increases the relay's durability.
• The AURATON RT receiver is equipped with a unique on-off cycle analysis algorithm. The entire heating cycle from the last 24 hours is saved in the RT receiver's memory. In the event of a loss of communication with the AURATON 200 RT controller and/or the T-2 thermometer, the RT receiver will automatically perform the memorized on/off cycle from the last 24 hours. This allows time to restore transmission (remove interference) or repair the 200 RT controller and/or the T-2 thermometer without significantly compromising thermal comfort in the controlled facility.
• Cooperation with optional devices (AURATON T-2 thermometer, 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 meter from the RT receiver (too strong a signal from the transmitters may cause interference).
• At least 30 seconds must pass between the next switching of the relay off and on.
• Data is transmitted from the AURATON 200 RT controller to the receiver whenever the ambient temperature changes by 0.2°C. If the temperature remains constant, the controller transmits control data every 5 minutes (this is indicated by the LED on the RT receiver flashing orange).
• In the event of a power outage, the RT receiver will turn off. When power is restored, the heating device will automatically turn on, and the RT receiver will wait for the next signal from the paired transmitters (this signal should arrive no later than 5 minutes after power is restored). Once the signal is received, the RT receiver will resume normal operation.
• Do not place the RT receiver in metal housings (e.g. mounting box, metal furnace housing) so as not to interfere with the operation of the controller.
• The AURATON 200 RT controller can be turned on or off at any time by briefly pressing the d .
• The first press of any function key always turns on the backlight, and only the next press activates the key function.
• When programming any function in the AURATON 200 RT controller, not pressing any button for 10 seconds is equivalent to pressing the d .
