Basic information

The Auraton TRA head with the Auraton 200 TRA controller is a programmable electronic room thermostat.
The Auraton TRA head is designed for mounting on M30x1.5 radiator inserts and, using a special adapter, on Danfoss RA-N valves (adapter included) or on underfloor heating manifolds with 30×1.5 mm thread. The Auraton TRA head communicates wirelessly with the Auraton 200 TRA controller by downloading information about the current room temperature and the set temperature. There can be any number of radiators with Auraton TRA heads in one room or there can be any number of circuits for a given room on the floor heating manifold, but they should all be paired with the same Auraton 200 TRA controller.

Choice of controller location

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 controller to the wall

To fix the AURATON 200 TRA 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. Holes for fixing screws.

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.

First start

Temperature setting

FrostGuard function

AURATON 200 TRA controller features the special FrostGuard function to protect the room from possible freezing. The function is activated even 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 various reasons, we would like to start reducing the room temperature by 3°C every day at the same time, it is possible to reduce it temporarily for a period of 6 hours. 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 andeveryday 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) symbol will disappear and only the room temperature will be displayed. The controller returns to the normal operating.

Head assembly

Heater with insert M30x1,5
or floor heating manifold

In order to mount the Auraton TRA head on a radiator or floor heating manifold with the most popular M30x1.5 insert on the market, perform the following actions:

1. Screw the reduction fitting A (1) onto the insert delivered with the head (all the way).
   
2. Take off the head battery cover (2) using a flat screwdriver.
   
3. Install two AAA batteries in the head, paying attention to their polarity. The pin of the head moves to the fully open position, which makes it easier to mount the head on the reduction fitting.
   
4. Slide the safety ring (3) into the “released” position.
   
5. Slide the head (4) all the way onto the reducing fitting A.
   
6. Turn the safety ring (3) into the “secured” position.
   
7. Pair the head with the Auraton 200 TRA, unless pairing has been done earlier.
8. Close the head
   

Heater with 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:

1. Put on the two halves of the reduction fitting B (1) onto the Danfoss RA-N insert.
   
2. Tighten all the way the reduction fitting A (2) on the installed reduction fitting B (1)
   
3. Perform steps 2 to 8 in chapter Heater with insert M30x1,5

Restore factory settings

1. Take off the head battery cover,
2. Take out the battery (one is enough).
3. Press the battery cover closing button (it is located on the electronics board between the batteries).
4. Hold the button down and install the batteries and wait about 4 seconds.
5. After you hear three beeps, release the button.

Pairing devices

Proper operation 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 settings (see the chapter “Restore factory settings”).
2. In the Auraton 200 TRA controller simultaneously press the buttons b d or c d for more than 3 seconds.
3. After 3 seconds, Auraton 200 TRA will send its ID to the Auraton TRA head, which will be signaled by a triple beep by the head.
4. After successfully pairing the Auratona 200 TRA and the head, close the battery cover (if installed on the radiator).

If the first pairing fails, do Restore factory settings, move closer to the head and perform pairing again.

Communication between the head and the controller and error signals

In order to save the battery, the Auraton 200 TRA controller communicates with the head every 2 minutes. Immediately after pairing the Auraton 200 TRA controller with the TRA head, the synchronization process takes about one minute. The synchronization process is not indicated in any way but is necessary for proper operation of the set.

If the radio communication is disturbed, e.g. due to the battery running out of the Auraton 200 TRA controller or during its replacement, the head will signal no communication, after 6 minutes lighting the LED every 8 [s]. After a maximum of 4 hours, the head should automatically re-synchronize with the Auraton 200 TRA. This time can be shortened to 2 minutes if, after losing synchronization, the flap is removed from the head and reassembled.

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

Signaling after startup of the head

After the battery is inserted, the head indicates that it is ready for operation by way of sound signals and a LED diode. There are two possible scenarios:

1. single beep – means that the Auraton 200 TRA controller is already paired with the TRA head. Just mount the head on the radiator insert or floor heating manifold and close the battery cover. After approx. 30 [s], the head will start 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 implement the temperature control algorithm. The pairing process described in chapter must be carried out Pairing devices.

Calibration error signals

After the head is installed on the radiator or floor heating manifold and the battery cover is closed, the head performs calibration of the mechanical system. If an error occurs during calibration, it is indicated with the buzzer sounding for 1 [s] every 1 [s]. If a calibration error occurs, the following must be checked:

1. Is the reduction fitting A properly screwed to the radiator insert or floor heating manifold?
2. Is the reduction fitting B (in the case of Danfoss inserts) properly fastened on the insert and is the reduction fitting A properly screwed into the reduction fitting B?
3. Is the safety ring properly set in the “secured” position?
4. Are the installed batteries not discharged (see the chapter “Method of installation of the TRA head on a radiator with an M30x1.5 insert” items 2. and 3.)
5. If the above-mentioned actions do not have the effect of correct calibration, this may indicate a malfunction of the radiator valve or floor heating manifold itself, or incompatibility of the head with this valve.

Installation tips

Auraton 200 TRA should be placed in the room where the head with the radiator is located or the room to which the relevant floor heating circuits are connected. It should not be placed next to a radiator, next to a door or in sunny places.

Battery life

The declared working time on one set of AAA alkaline batteries is one year. Discharging the battery does not affect temperature control. The head indicates a low battery level by lighting the LED twice every 8 [s]. In addition, when the battery discharges even more, the head begins to generate a double beep every 8 minutes. To turn off the sound signaling for 24 hours, press any key on the Auraton 200 TRA paired with this head, or raise the head flap for 2 [s] and reinstall it.
After 24 hours, the signaling will turn on again, reminding you to replace it battery. Then again we can turn off the signaling for another 24 hours, but this process will repeat until the batteries are replaced.
