AURATON Apus

User manual ver. 20201007
This document collects information on the safety, installation and use of the AURATON Apus device.

Electronic radiator head

The AURATON Apus is an electronic radiator valve 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 Apus communicates wirelessly with the AURATON Apus R, collecting information about the current room temperature and the setpoint temperature. A single room can contain any number of radiators with AURATON Apus valves, 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 Apus R.

Description of AURATON Apus

The AURATON Apus head works with the AURATON Apus R 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.

AURATON Apus installation

Radiator with M30x1.5 insert
or underfloor heating distributor

To mount AURATON Apus on a radiator or underfloor heating manifold with an M30x1.5 insert, perform the following steps:

  1. Screw the reduction A (1) included in the AURATON Apus kit onto the insert (as far as it will go).
  2. Remove the battery cover (2) of the AURATON Apus using a flat screwdriver.
  3. Install two AAA batteries into the AURATON Apus, observing polarity. The head pin will move to the fully open position, making it easier to mount the AURATON Apus on the adapter.
  4. Move the locking ring (3) to the “unlocked” position.
  5. Slide the AURATON Apus (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 AURATON Apus R if such procedure has not been performed before.
  8. Close the battery cover (2) of the Auraton Apus.

Radiator with Danfoss RA-N insert

To install AURATON Apus 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

Device pairing

For the AURATON Apus head to work correctly, it must be paired with the AURATON Apus R controller. The pairing process is as follows:

  1. Restore the AURATON Apus to factory settings (see the section "Restoring the head to factory settings")
  2. In AURATON Apus R b d or c d buttons simultaneously for more than 3 seconds.
  3. After a 3-second countdown, AURATON Apus R will send its identifier to AURATON Apus, which will be signaled by the head with a triple beep.
  4. Once the AURATON Apus R has been successfully paired with the AURATON Apus, close the battery cover (if it was already mounted on the radiator).

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

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

AURAON Apus R communication with AURATON Apus and error indication

To conserve battery power, the AURATON Apus R communicates with the AURATON Apus periodically every 2 minutes. Immediately after pairing the AURATON Apus R with the AURATON Apus, 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, e.g. due to a depleted battery in the AURATON Apus R or during its replacement, the AURATON Apus will signal a loss of connection by lighting the LED every 8[s] after 6 minutes. After a maximum of 4 hours, the head should automatically resynchronize with the AURATON Apus R. This time can be shortened to 2 minutes if, after losing synchronization, the cover is removed from the AURATON Apus and reattached.

Even if communication between the AURATON Apus R and the AURATON Apus is disrupted, the user should not experience any deterioration in comfort. The AURATON Apus will automatically stabilize the room temperature at the level it remembered before losing communication with the AURATON Apus R.

Signaling after starting AURATON Apus

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

  1. A single beep means that the AURATON Apus is already paired with the AURATON Apus R. Simply mount the AURATON Apus on the radiator insert or underfloor heating manifold and close the battery cover. After approximately 30 [s], the AURATON Apus will start regulating the temperature.
  2. triple beep – AURATON Apus is not paired with AURATON Apus R. After closing the battery cover, AURATON Apus WILL NOT execute the temperature regulation algorithm. It is necessary to complete the pairing process described in the Pairing Devices section.
NOTE:
If the AURATON Apus 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 the installation of the AURATON Apus.

Calibration error indication

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

  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: "Radiator with M30x1.5 insert or underfloor heating manifold" points 2 and 3)
  5. If the above-mentioned actions do not result in correct calibration, this may indicate incorrect operation of the radiator valve or underfloor heating manifold itself, or incompatibility of AURATON Apus with this valve.

Assembly instructions

The AURATON Apus R should be placed in a room where there is an AURATON Apus with a radiator or in a room to which 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 AURATON Apus 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 signal for 24 hours, press any key on the AURATON Apus R paired with the AURATON Apus, or lift the AURATON Apus cover for 2 seconds and replace it.
After 24 hours, the signal will turn on again, reminding you to replace the batteries. You can then turn the signal off again for another 24 hours, but this process will repeat until the batteries are replaced.

Unique features of AURATON Apus SET

  • Auraton Apus R and Auraton Apus "learn" the room in the first phase of use to control the heating as precisely as possible.
  • Initially, temperature fluctuations may be greater, but will decrease over time.

Cleaning and maintenance

  • Clean the exterior of the device with a dry cloth. Do not use solvents (such as benzene, thinner, or alcohol).
  • Do not touch the device with wet hands. This may cause 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.

RESET – restoring factory settings AURATON Apus

  1. Remove the AURATON Apus 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.
