Choosing the right location for AURATON Draco R

The proper operation of the AURATON Draco R is significantly affected by its location. Siting it in a location lacking air circulation or exposed to direct sunlight may result in improper temperature control. The AURATON Draco R should be installed on an interior wall (partition wall), in an environment with free air circulation. Avoid proximity to heat-emitting devices (TV, radiator, refrigerator) or locations exposed to direct sunlight. Proper operation may be impaired by proximity to doors, which may expose the AURATON Draco R to potential vibration.

Battery replacement

The battery compartment is located inside the AURATON Draco R on the front of the housing. To install the batteries, remove the AURATON Draco R housing as shown in the figure below:

NOTE:
We recommend alkaline batteries for powering AURATON controllers. Rechargeable batteries should not be used due to their low rated voltage.
  1. – 1.5V AAA battery slot

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

Mounting the AURATON Draco R – a weekly, wireless temperature controller

To attach AURATON Draco R to the wall:

  1. Remove the cover (as shown in the "Replacing the Battery" section)
  2. Drill two 6 mm diameter holes in the wall (mark the hole spacing using the rear part of the AURATON Draco R housing).
  3. Insert the expansion bolts into the drilled holes.
  4. Screw the rear part of the AURATON Draco R housing to the wall using the screws included in the kit.
  5. Put the casing 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.

    • Pressing the buttonn will switch the editing mode between day and night temperature ( S , T ).
    • After setting the temperatures, confirm everything with the button. (.
    NOTE:
    The night temperature setting must be lower than the day temperature. It is not possible to set the night temperature higher than the day temperature.

    Introduction to programming

    Timeline

    The timeline on the LCD display is divided into 24 sections, each representing one hour of the day.
    Black rectangles above the timeline indicate that the program has set the daytime temperature for that time; their absence indicates that the program has set the nighttime temperature.

    Example:

    The figure above shows that from 6:00 a.m. to 11:00 p.m., the AURATON Draco R will control the heating or air conditioning device to maintain the room at day temperature ( S ). From 11:00 p.m. to 6:00 a.m., the AURATON Draco R will switch to night temperature ( T ).

    Factory programs

    To ensure the AURATON Draco R knows when to switch to the day and night temperatures, you need to set a specific program for each day of the week. To do this, you can use one of three preset programs (from 0 to 2):

    Program No. 0 – Anti-freeze. U
    This factory program cannot be modified. Designed for setting the anti-freeze temperature all day long.

    Program No. 1 – Weekly
    . Non-modifiable factory program. Sets the daily temperature from 5:00 to 8:00 and from 15:00 to 23:00.

    Program No. 2 – Weekend
    . This factory program cannot be modified. It sets the daily temperature from 6:00 a.m. to 11:00 p.m.

    Program No. 3, 4,…, 8 – User
    Programs No. 3 through No. 8 are user programs. They can be freely modified and adapted to your requirements.

    Programming

    Weekly programming

    Programming the AURATON Draco R involves specifying the hours for a given day of the week during which the daytime temperature should be maintained. The nighttime temperature then applies.

    Example AURATON Draco R from Monday to Sunday. Outside the time periods specified below, the AURATON Draco R will maintain a lower night-time temperature.

    DayDaytime temperature
    Monday5:00 – 8:00; 15:00 – 23:00
    Tuesday5:00 – 8:00; 15:00 – 23:00
    Wednesday5:00 – 8:00; 15:00 – 23:00
    Thursday5:00 – 8:00; 15:00 – 23:00
    Friday5:00 – 8:00; 15:00 – 23:00

    4. All 24 black rectangles on the timeline will be lit, each representing one hour. A visible rectangle indicates that the daytime temperature is to be achieved at that hour. The absence of a rectangle above the timeline indicates that the nighttime temperature is scheduled.

      The flashing rectangle indicates where on the timeline we are making changes.

    5. Use the buttonr to select the day temperature (light rectangle) or night temperature (light rectangle). Then, use the knob to select the time interval for the given temperature.

    6. By pressing the buttonr and selecting the time interval, we modify the entire program.

    7. We confirm everything with the button (

    NOTE:
    A modified program for a specific day can be selected and implemented also on another day of the week.

    Manual control

    V

    Option 1:
    If for any reason you wish to interrupt the current program and extend the day or night temperature, you can do so manually, but for no longer than 24 hours. To do this:

    Hold the buttonr for 3 seconds. Then use the knob to select the number of manual operation hours (maximum 24 hours) and confirm the setting by pressing the button( .

    The AURATON Draco R will wait for you to set the desired temperature (day or night). Changes can be made using the buttonr or the knob. Confirm your selection by pressing the button( .

    Option 2:
    If you would like to suspend the program, e.g., due to a prolonged party, and the AURATON Draco R has already started lowering the temperature to the night temperature (the T ), and you would like to maintain the comfortable temperature until the end of the party, proceed as follows:
    Press the buttonr the V and S symbols will appear on the display . The day temperature will then be maintained until the next temperature change implemented by the program.
    To cancel this function, press the button( ; the symbol will disappearr from the display.

    Similarly, if the program is maintaining the day temperature, and you want to immediately enter the night temperature, then:
    Press the buttonr V and T symbols will appear on the display . The night temperature will then be maintained until the next temperature change implemented by the program. To cancel this function, press the button( ; the symbol will disappearr from the display.

    Antifreeze temperature

    U

    In the event of an extended absence, you can activate the anti-freeze temperature mode. This prevents the unpleasant consequences of water freezing in the heating system by automatically setting the temperature to 7°C. To set the anti-freeze program, simply select program 0 on the desired day of the week.

    Evaporation

    AURATON Draco R weekly, wireless temperature controller (transmitter) with AURATON Fornax receiver, controller of a heating or air-conditioning device

    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.

    NOTE:
    The wireless AURATON Draco R (transmitter) sold together with the AURATON Fornax wireless heating or air conditioning controller (receiver) in the AURATON Draco SET is already paired. Devices purchased separately require "pairing."
    1. Pairing the AURATON Draco R (transmitter) with the AURATON Fornax is initiated by pressing the right pairing button ( D ) – a single beep on the AURATON Fornax receiver – and holding it for at least 3 seconds until the LED starts flashing green (double beep), then releasing the button.
      The AURATON Fornax receiver waits 120 seconds for pairing. After this time, it will automatically return to normal operation.
    2. On the AURATON Draco R (transmitter), press the buttonh for 5 seconds until the transmitting symbol (W ) lights up on the display. Release the button – the AURATON Draco R transmits a pairing signal for 5 seconds.
    3. Successful completion of pairing is indicated by the LED on the AURATON Fornax 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. In case of subsequent errors, unpair the device by RESETting the AURATON Fornax receiver, see "RESET - Unpairing the device from the AURATON Fornax - wireless controller of a heating or air-conditioning device (receiver)" and try pairing the devices again.

    NOTE:
    The Auraton Fornax receiver can only be paired with one AURATON Draco R.

    Signaling of operation and receipt of data packets

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

    NOTE:
    Pressing any button is signaled by a short beep.

    Writing off AURATON Draco R – a weekly, wireless temperature controller from AURATON Fornax

    1. Unlinking the AURATON Draco R (transmitter) from the AURATON Fornax receiver is initiated by pressing the left unlink button ( E ) on the receiver and holding it for at least 3 seconds until the LED flashes red, then releasing 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 Fornax receiver waits 120 seconds for the device to be unlinked. After this time, it will automatically return to normal operation.
    2. On the AURATON Draco R (transmitter), press the buttonh for 5 seconds until the transmitting symbol ( W ) lights up on the display. Release the button.
    3. Successful completion of the write-back is indicated by the LED on the AURATON Fornax receiver stopping flashing red, a single sound signal and the receiver switching to normal operation.

    If an error occurs during unsubscribing, repeat steps 1 and 2. In case of subsequent errors, unsubscribe the paired device, see "RESET – Unsubscribing a device paired to AURATON Fornax – wireless controller of a heating or air-conditioning device (receiver)" .

    RESET – Unpairing the device paired with the AURATON Fornax receiver – wireless controller of a heating or air conditioning device (receiver)

    To unpair a paired device (e.g., a controller) from AURATON Fornax, simultaneously press and hold both the pairing and unpairing buttons ( D and 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 produces a short beep – after 5 seconds, a double short beep.
    Successful unpairing of the device is indicated after approximately 2 seconds by the indicator changing to green and then briefly fading.

    NOTE:
    If you disconnect the AURATON Fornax receiver from the power supply after a RESET and then reconnect it, the receiver will automatically enter "pairing" mode for 120 seconds. A newly purchased AURATON Fornax receiver (not included with the AURATON Draco R) that does not have factory-paired devices will behave identically.

    RESET AURATON Draco R

    Reset is performed by removing the battery until the data disappears from the display.

    MASTER RESET AURATON Draco R

    MASTER RESET is performed by pressing and holding the button( while inserting the batteries. This returns the AURATON Draco R to its factory settings.

    NOTE:
    All user programs are deleted!

    Configuration settings

    Configuration settings are made sequentially:

    heating mode/
    air conditioning mode

    hysteresis change

    offset change

    To enter the configuration settings change mode, hold down theh and( for 3 seconds until the settings menu is displayed.

    Heating mode/Air conditioning mode

    AURATON Draco R can operate in two modes:

    Heating mode (factory set) – set it when AURATON Draco R is to cooperate with heating devices.
    Air conditioning mode – set it when AURATON Draco R is to cooperate with air conditioning devices.

    Turn the knob left or right to set the desired mode. Confirm your selection by pressing the button( . AURATON Draco R will move on to the next parameter.

    Hysteresis change

    Hysteresis is designed to prevent the actuator from switching on too frequently due to minor temperature fluctuations.
    For example, for HI 2 hysteresis, with the temperature set to 20°C, the boiler will turn on at 19.8°C and turn off at 20.2°C. For 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.

    The hysteresis change mode is indicated by the flashing HI sign. Turn the knob left or right to set the desired hysteresis.
    HI 2 – ±0.2 °C (factory setting),
    HI 4 – ±0.4 °C.

    Confirm the selection by pressing the button( . AURATON Draco R will move on to changing the next parameter.

    Offset change

    Offset allows you to calibrate temperature readings with a tolerance of ±3°C. For example, the AURATON Draco R indicates that the room temperature is 23°C, while a standard room thermometer hanging next to it reads 24°C. By changing the offset by +1 degree, the AURATON Draco R will display the same temperature as the room thermometer.

    Offset change mode is indicated by the flashing OFFS sign. Turn the knob left or right to set the desired value within the range of -3.0 to 3.0 (factory setting – 0.0). Confirm the selection by pressing the button( . AURATON Draco R returns to normal operation.

    NOTE:
    If you do not press any button for 10 seconds while changing the configuration settings, AURATON Draco R will return to normal operating mode.
    NOTE:
    The first press of any function button always turns on the backlight, and only the next press activates the button function.

    Special situations

    • If we lose three consecutive transmissions (after 15 minutes) from the AURATON Draco R (transmitter), a failure will be signaled on the AURATON Fornax receiver (the LED will continuously flash alternately red and green). Until the problem is resolved, the receiver will revert to the memorized on/off cycle from the last 24 hours.
    • When the signal from AURATON Draco R returns, the error is cleared and the AURATON Fornax receiver switches to normal operation.

    Additional notes

    • AURATON Draco R (transmitter) must be installed at least 1 meter from the receiver (too strong a signal from the transmitter may cause interference).
    • At least 30 seconds must pass between the next switching off and switching on of the relay.
    • Data is transmitted from the AURATON Draco R (transmitter) to the AURATON Fornax receiver whenever the ambient temperature changes by 0.2°C. If the temperature does not change, the AURATON Draco R transmits control data every 5 minutes (this is indicated by a flashing orange LED on the receiver).
    • In the event of a power outage, the AURATON Fornax receiver will turn off. When power is restored, the heating device will automatically turn on, and the AURATON Fornax receiver will wait for a signal from the paired AURATON Draco R (transmitter) for a maximum of 5 minutes after power is restored. Once the signal is received, the AURATON Fornax receiver will resume normal operation.
    • Placing the AURATON Fornax receiver in a metal housing (e.g. mounting box, metal furnace housing) will interfere with the operation of the AURATON Draco R.
    • In AURATON Draco R (transmitter) you can turn the control functions on or off at any time (e.g. after the heating season) by briefly (approx. 5 seconds) holding the button( (AURATON Draco R will only show the current time and room temperature – no "timeline").
    • The first press of any function button always turns on the backlight, and only the next press activates the key's function. When using the knob, each step keeps the backlight on.
    • When programming any function, not pressing any button for 10 seconds is equivalent to pressing the button. (.
