Basic information

The Auraton TRA head, together with the Auraton 200 TRA controller, is a programmable, electronic room thermostat.
The Auraton TRA head is designed for installation on M30x1.5 radiator inserts and, using a special adapter, on Danfoss RA-N valves (adapter included) or on underfloor heating manifolds with a 30x1.5 mm thread. The Auraton TRA head communicates wirelessly with the Auraton 200 TRA controller, collecting information about the current room temperature and the setpoint temperature. A single room can contain any number of radiators with Auraton TRA heads, or an underfloor heating manifold can have any number of circuits for a given room, but all of them must be paired with the same Auraton 200 TRA controller.

Selecting the location of the regulator

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.

NOTE:
We recommend alkaline batteries for powering AURATON controllers. Rechargeable batteries should not be used due to their low rated voltage.

Mounting the regulator to the wall

To attach the AURATON 200 TRA 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.
NOTE:
If you have a wooden wall, there is no need to use expansion bolts. Simply drill 2.7mm holes (instead of 6mm) and drive the screws directly into the wood.
NOTE:
Do not mount the Auraton 200 TRA controller on metal surfaces, as this significantly reduces the range of radio communication.
  1. Holes for mounting screws.

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.

First start-up

Once the batteries are properly inserted, the LCD display will show all segments for a second (display test), followed by the software version number. After a moment, the current temperature will be displayed. The controller is ready for operation.

Temperature setting

NOTE:
The first press of any function key always turns on the backlight, and only the next press activates the key function.
To set the desired (set) temperature in normal operation mode, you should:
  1. Press the b or c . The temperature display segment will enter edit mode and start flashing.
  2. b and c buttons to set the desired (set) temperature with an accuracy of 0.2°C
  3. Confirm your selection by briefly pressing the d

FrostGuard function

AURATON 200 TRA thermostat is equipped with a special "FrostGuard" function that protects the room from possible freezing. This function is activated even 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 start lowering the room temperature by 3°C at the same time each day, you can temporarily reduce it for a period of 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.

NOTE:
After 6 hours, the thermostat will return to the basic temperature setting. Instead of the moon symbol ( T ), the sun symbol ( ) will appear on the screenS .
NOTE:
The "temporary temperature reduction" mode always begins when the function is enabled. This means that the temporary 3°C temperature reduction should be activated exactly when you want the change to begin.
NOTE:
Enabling the temporary 3°C temperature reduction function does not guarantee that such a reduction will occur within 6 hours. This depends on the building's thermal inertia.

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.

Head description

The AURATON TRA head works with the AURATON 200 TRA wireless controller. The head is mounted directly on the radiator or underfloor heating manifold.

  1. – Battery cover closing, pairing and reset button.
  2. – Indicator diode.

Head assembly

Radiator with M30x1.5 insert
or underfloor heating distributor

To mount the Auraton TRA head on a radiator or underfloor heating manifold with the most popular M30x1.5 insert on the market, perform the following steps:

  1. Screw the reduction A (1) included in the head set onto the insert (as far as it will go).
  2. Remove the battery cover (2) from the head using a flat screwdriver.
  3. Install two AAA batteries into the head, observing polarity. The head's stem will move to the fully open position, making it easier to mount the head on the adapter.
  4. Move the locking ring (3) to the “unlocked” position.
  5. Slide the head (4) onto the reduction A (5) as far as it will go.
  6. Turn the locking ring (3) to the “secured” position.
  7. Perform the pairing procedure with the Auraton 200 TRA if this procedure has not been performed before.
  8. Close the battery cover (2) of the head.

Radiator with Danfoss RA-N insert

To mount the Auraton TRA head on a radiator with a Danfoss RA-N insert:

  1. Place 2 halves of the B reduction (1)
  2. On the assembled reduction B (1), tighten the reduction A (2)
  3. Carry out steps 2 to 8 in the Radiator with M30x1.5” insert section

Restoring the head to factory settings

  1. Remove the head battery cover.
  2. Remove the battery (one is enough).
  3. Press the battery cover close button (located on the electronics board between the batteries.)
  4. While holding the button down, install the batteries and wait approximately 4 seconds.
  5. When you hear three beeps, release the button.

Device pairing

For the Auraton TRA head to operate correctly, it must be paired with the Auraton 200 TRA controller. The pairing process is as follows:

  1. Restore the Auraton TRA to factory settings (see the section "Restoring the head to factory settings")
  2. On the Auraton 200 TRA b d or c d buttons simultaneously for more than 3 seconds.
  3. After a 3-second countdown, the Auraton 200 TRA will send its identifier to the Auraton TRA head, which will be signalled by the head with a triple beep.
  4. Once the Auraton 200 TRA and the head have been successfully paired, close the battery cover (if it was already mounted on the heater).

If the first pairing fails, perform a factory reset , move closer to the head and pair again.

NOTE:
The AURATON 200 TRA wireless controller sold with the AURATON TRA head is already paired. Devices purchased separately require pairing.

Head-controller communication and error signaling

To conserve battery power, the Auraton 200 TRA communicates with the head periodically every two minutes. Immediately after pairing the Auraton 200 TRA controller with the TRA head, a synchronization process occurs, lasting approximately one minute. This synchronization is not signaled but is necessary for the set to function properly.

If radio communication is disrupted, for example, due to a depleted battery in the Auraton 200 TRA controller or during battery replacement, the head will signal a loss of communication by flashing the LED every 8 seconds after 6 minutes. After a maximum of 4 hours, the head should automatically resynchronize with the Auraton 200 TRA. This time can be shortened to 2 minutes by removing and reattaching the cover after the synchronization is lost.

Even if communication between the thermostatic head and the Auraton 200 TRA is disrupted, the user should not experience any deterioration in comfort. The thermostatic head will automatically stabilize the room temperature at the level it remembered before losing communication with the Auraton 200 TRA controller.

Signaling after starting the head

After inserting the batteries, the head signals its readiness with an audible signal and an LED. Two scenarios are possible:

  1. A single beep indicates that the Auraton 200 TRA controller is already paired with the TRA head. Simply mount the head on the radiator insert or underfloor heating manifold and close the battery cover. After approximately 30 seconds, the head will begin regulating the temperature.
  2. Triple beep – the Auraton 200 TRA controller is not paired with the head. After closing the battery cover, the head WILL NOT execute the temperature control algorithm. It is necessary to complete the pairing process described in the Pairing Devices section.
NOTE:
If the head pressure pin was not in the fully open position, the motor will also start and the actuator will move to the rear position to facilitate head assembly.

Calibration error indication

After mounting on a radiator or underfloor heating manifold and closing the battery cover, the head calibrates the mechanical system. If an error occurs during calibration, it is signaled audibly by the speaker sounding for 1[s] every 1[s]. If a calibration error occurs, check:

  1. Is the A reduction properly screwed to the radiator insert or underfloor heating manifold?
  2. Is the B reduction (in the case of Danfoss inserts) correctly fastened to the insert and is the A reduction correctly screwed into the B reduction?
  3. Is the locking ring correctly set to the “secured” position?
  4. Are the installed batteries discharged (see chapter: "Method of mounting the TRA head on a radiator with an M30x1.5 insert" points 2 and 3)?
  5. If the above-mentioned activities do not result in correct calibration, this may indicate incorrect operation of the radiator valve or underfloor heating manifold itself, or incompatibility of the head with this valve.

Assembly instructions

The Auraton 200 TRA should be placed in the room where the radiator head is located or in a room to which the appropriate underfloor heating circuits are connected. It should not be placed next to a radiator, near a door, or in direct sunlight.

Battery life

The declared operating time on a single set of AAA alkaline batteries is one year. Discharging the batteries does not affect temperature control. The head signals a low battery by flashing the LED twice every 8 seconds. Additionally, when the battery becomes even more discharged, the head will begin to emit a double beep every 8 minutes. To turn off the audible alarm for 24 hours, press any key on the Auraton 200 TRA paired with this head, or lift the head cover for 2 seconds and reinstall it.
After 24 hours, the alarm will turn on again, reminding you to replace the batteries. You can then turn the alarm off again for another 24 hours, but this process will repeat until the batteries are replaced.
