Radiator Controller

User manual ver. 1.3
This document collects information on the safety, installation and use of the Auraton Radiator Controller.

Basic information

The Auraton Radiator Controller head, along with the Auraton Heat Monitor, is a programmable, electronic room thermostat. The head is designed for installation on M30x1.5 radiator inserts and, using a special adapter, on Danfoss RA-N valves (adapter included). The head communicates wirelessly with the Auraton Heat Monitor, collecting information about the current room temperature and the setpoint temperature. It is possible to control up to three radiators in a single room with Auraton Radiator Controller heads, but all of them must be paired with the same Auraton Heat Monitor.

Optional system components

The Auraton Radiator Controller head is designed to work with the Auraton Heat Monitor regulator and the Auraton Pulse internet control unit, which allows you to control operating parameters using a phone or tablet application.

Head description

The head is mounted directly on the radiator or on the underfloor heating manifold.

Head assembly

Radiator with M30x1.5 insert

To mount the Auraton Radiator Controller head on a radiator 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, which is necessary 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 Heat Monitor or Auraton Pulse if this procedure has not been performed previously.
8. Close the battery cover (2) of the head.
   

Radiator with Danfoss RA-N insert

To mount the Auraton Radiator Controller 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

Assembly instructions

The Auraton Heat Monitor should be placed in the room where the radiator controller is located. It should not be placed near the radiator, near a door, or in direct sunlight. The controller should be mounted on a radiator insert, no more than 20 cm from the radiator. In almost all cases, this requirement is met, as manufacturers integrate the radiator inserts with the radiators. If the controller is located further away from the radiator (the radiator is not directly heating it), the temperature control will be less dynamic. Larger fluctuations in room temperature may occur. However, mounting the Auraton Radiator Controller controller on inserts located at the bottom of the radiator (common bathroom towel rails) is permitted.

Pairing devices

For the Auraton Radiator Controller to function correctly, it must be paired with the Auraton Heat Monitor or the Auraton Pulse internet control unit. Pairing mode is indicated on the controller by a flashing red LED. A maximum of three Radiator Controllers can be paired with a single Heat Monitor. The pairing process is as follows:

1. Remove the battery cover (preferably with a flat screwdriver).
2. Wait for the engine to finish moving.
3. Press the black battery cover closing button on the electronics board 3 times (quickly).
4. Enable pairing mode on the second device you want to pair (examples described below).
5. Wait for the triple beep, which confirms successful pairing of the devices.
6. Close the battery cover (if already mounted on the radiator).

If the first pairing fails, restore the factory settings , move closer to the control unit and pair again.

Enabling pairing – Heat Monitor controller

On the Auraton Heat Monitor controller, press theb d orc d for 3 seconds until the transmission symbol (W ) lights up on the display. The Auraton Heat Monitor controller waits 30 seconds for pairing. After this time, it will automatically return to normal operation.

Enabling pairing – Auraton Pulse control panel

Pairing in Auraton Pulse is enabled using the Auraton Smart App. After launching the app, press the green plus button in the center of the screen. When the next screen appears, tap the house icon labeled "Devices." On the next screen, name the device you're adding. After entering the name, press the "Add" button. Once successfully paired, you can place the device in any previously added room and add it to your favorites.

Factory reset

Restoring factory settings erases all configuration data from the Auraton Radiator Controller, including all associated devices. The procedure is as follows:

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

Device functions

How does the heating function work?

The Auraton Radiator Controller smoothly controls heating based on its own temperature measurement (less precise control) or an external temperature sensor, such as the Heat Monitor (more precise control). Based on the external temperature measurement (recommended), the algorithm decides the percentage by which a valve, such as a radiator valve, must be opened to achieve the set temperature after taking into account a certain amount of thermal inertia.

Valve descaling function

To prevent scale buildup in the radiator valve, the Radiator Controller head opens it periodically. Once opened, all accumulated scale is flushed out, allowing the head to operate properly. This function is activated once every two weeks. Additionally, a mode is added that partially opens the valve each time the target temperature changes to flush out any minor scale that may have accumulated.

Function to restore the previous software

The purpose of this function is to downgrade the software to the previous version if it malfunctions after an update. The entire process can take up to a minute, and the device must remain powered on during this time. The previous version of the program is always loaded. If the program was previously downgraded from version 1.6 to 1.5, the previous version is 1.6.

1. Remove the head battery cover, preferably with a flat screwdriver.
2. Remove one battery.
3. Press the battery cover close button (located on the electronics board between the batteries).
4. While holding the button down, install the batteries.
5. After hearing the three beeps, do not release the button until the next audio information (four beeps), then release the button.

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. 1. A single beep indicates that the thermostatic head is paired with another device. Simply mount the thermostatic head on the radiator insert and close the battery cover. After approximately 30 seconds, the thermostatic head will begin regulating the temperature.
   2. A triple beep indicates that no device is associated with the head. The head will stabilize its internal temperature at 20 degrees Celsius. This operation is not recommended due to the temperature difference between the head operating near a radiator and the room temperature. Furthermore, a Radiator Controller head operating without an associated Auraton Heat Monitor will draw more current and drain the batteries more quickly.

Calibration error indication

After mounting on the radiator and closing the battery cover, the head calibrates the mechanical system. If an error occurs during calibration, it is signaled audibly by the speaker turning on for 1 second every 1 second. If a calibration error occurs, check the following:

1. 1. 1. Is the A reduction properly screwed to the radiator insert?
      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?

Battery life and low battery indication

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 low battery by flashing the LED twice every 8 seconds. Additionally, when the battery becomes even more depleted, the head will begin to beep twice every 8 minutes. To turn off the audible signal for 1 day, press any button on the Auraton Heat Monitor associated with the head, or lift the head cover for 2 seconds and reinstall it.

Device operating modes

The Auraton Heat Monitor set together with the Auraton Radiator Controller head can operate in two modes:

Mode I (local):
In this mode, the thermostat and radiator head can operate independently without the need for the Auraton Pulse internet control unit. The Auraton Heat Monitor thermostat must be correctly assigned to the Auraton Radiator Controller. Up to three radiator heads can be assigned to a single thermostat.

Mode II (remote):
In remote mode, the Auraton Pulse internet control unit can be used, providing access to the entire system while away from home.
This allows remote heating control, checking battery charge levels, receiving event notifications, creating schedules, and much more.

Cooperation with Auraton Pulse headquarters

The Radiator Controller thermostatic head is paired with the Auraton Pulse control unit just like with other devices (as described in the section on pairing devices). The only difference is that pairing mode is activated on the control unit through the app by pressing the green plus sign at the bottom of the screen and then clicking the "Devices" icon. Details are described in the app's user manual. The image below shows the head's control screen in the app, showing the following parameters: current temperature, target temperature, battery charge percentage, radiator valve opening percentage, device status (on/off), and a position from 0 to 5 (a read-only parameter, showing how far the valve is open compared to a traditional mechanical head). The last two parameters can be changed in separate tabs, which are accessed by pressing the "Status" or "Position" icons.

The Radiator Controller thermostatic head is primarily designed to work with the Heat Monitor regulator and the Heater Controller thermostatic furnace switch. The app allows you to easily link the head to the thermostat by creating two "Group" functions. One function should group the current temperature, and the other the target temperature; then, any changes on each device will be sent to the others. If the system is installed in a home where the furnace is switched on by the Auraton Heater Controller, it is possible to link all installed heads to the furnace using the "Heating" function. This function ensures that if the radiator valve opening of any of the connected heads is above 0%, the furnace is switched on.
