Choosing the right location for AURATON Tucana R

The correct operation of AURATON Tucana R is largely influenced by its location. Using the device in a place with no air circulation or a place with direct sunlight may result in incorrect temperature control. AURATON Tucana R should be installed on the internal wall of a building (a partition wall), in an environment with free air circulation. You should avoid proximity to heat-emitting devices (TV, heaters, refrigerators) or locations exposed to direct sunlight. The vicinity of doors and exposing AURATON Tucana R to possible vibrations may also cause problems with proper operation of the device.

Battery replacement

X

If the low battery symbol (X) appears on the display, it means that the battery level has fallen to the minimum allowable level. Replace the batteries as soon as possible.

Mounting AURATON Tucana R – weekly, wireless thermostat

To mount AURATON Tucana R to the wall:

1. Drill two holes 6 mm in diameter in the wall (mark the hole spacing using the template attached to the manual).
2. Insert the wall plugs (included).
3. Tighten the left screw with a 3 mm clearance.
4. Place AURATON Tucana R through the screw head and slide to the right (note the keyhole-like opening on the rear cover of AURATON Tucana R).

3. Use the bc buttons to set the desired temperature.
4. By pressing the ? button again, toggle between the subsequent types of temperatures to be set (S, T, U).
5. After setting all the 3 temperatures, confirm the settings with the i button.

Introduction to programming

Timeline

The timeline on the LCD display is divided into 24 sections. Each of them symbolizes 1 hour of the day.
Black rectangles above the timeline mean that the day temperature has been programmed for specific hours, and that there is no night temperature.

Example:

The figure above shows that from 6.00 A.M. to 11.00 P.M. Auraton Tucana R will control the heating device in such a way that the room temperature will be day temperature (S). AURATON Tucana R will switch to night temperature (T) from 11.00 P.M. to 6.00 A.M.

Factory programs

In order for AURATON Tucana R to know when to turn on the day and night temperatures, you should be set to an appropriate program for each day of the week. For this purpose, you can use one of the three factory programs (from 0 to 2):

Program no. 0 – anti-freezing U
Unmodifiable factory program. Designed for all-day anti-freezing temperature setting.

Program no. 1 – weekly
Unmodifiable factory program. Sets day temperature from 5:00 to 8:00 A.M. and from 3:00 to 11:00 P.M.

Program no. 2 – weekend
Unmodifiable factory program. Sets day temperature from 6:00 A.M. to 11:00 P.M.

Programs no. 3, 4,…., 9 – user-defined programs
Programs from 3 to 9 are user-defined programs. They can be freely modified and adapted to specific requirements.

Programming

Weekly programming

In order to program the AURATON Tucana R, it is necessary to decide on which day of the week and during what period of time the day temperature should be maintained. During the remaining time, the night temperature will be maintained.

An exemplary mode of operation of the AURATON Tucana R from Monday until Sunday. Besides the defined periods of time, the AURATON Tucana R maintains the lower night temperature.

Day of week	Day temperature
Monday	5:00 – 8:00; 15:00 – 23:00
Tuesday	5:00 – 8:00; 15:00 – 23:00
Wednesday	5:00 – 8:00; 15:00 – 23:00
Thursday	5:00 – 8:00; 15:00 – 23:00
Friday	5:00 – 8:00; 15:00 – 23:00
Saturday	8:00 – 23:00
Sunday	8:00 – 23:00

Selecting a program

In order to select a program:

2. Press the l button. Using the bc buttons or the l button set the day of the week when the program should be executed.

   

3. Pressing the h button several times, select the desired program number. Programs no. 0-2 are factory-defined and programs no. 3-9 can be modified.

   

4. Confirm the setting with the i button.
5. Return to step 1 and repeat the above procedure for the next day of the week. Programming can end when each day of week is assigned an appropriate program.

Modifying user programs

In order to modify a program:

1. Press the h button. The program description field starts flashing.

   

2. 
   Press the l button. Using the bc buttons or the l button, set the day of the week when the program should be executed.
   

   

3. Press the h button several times and select program number 3 to 9 (user modifiable).

   

4. All (24) black rectangles will be lit on the timeline, each symbolising 1 hour. A visible rectangle means that the day temperature is to be achieved during a given hour. No rectangle above the timeline is tantamount to planning the night temperature.

   A flashing rectangle indicates the place where changes are being made on the timeline.

   

5. Press the ; or : button to select the day temperature (a lit rectangle) or the night temperature (no rectangle) on the timeline.

   

6. 
   Use the bc buttons to highlight subsequent hours on the timeline and select the day or night temperature for each hour (we toggle between a lit rectangle and no rectangle with the ; : buttons).
   

   

7. After modifying the whole timeline, save the program with the i button.

Manual control

V

If you want to discontinue the current program operation and extend maintaining the day temperature for any reason, you can do it manually. To do this, you should:

1. Press the : button. The V symbol appears on the display. The comfort temperature will then be maintained until the next change of temperature to be achieved by the program.
2. To deactivate the above-mentioned function, press the i button located under the battery cover – the V symbol will then disappear from the display.

Similarly, if you want to discontinue the current program operation and extend maintaining the night temperature for any reason, you should:

1. Press the ; button. The V symbol appears on the display. The comfort temperature will then be maintained until the next change of temperature to be achieved by the program.
2. Press the i button to deactivate the above-mentioned function.

Holiday mode

We sometimes leave our homes for longer periods. To avoid reprogramming the whole AURATON Tucana R device, we can use the holiday mode, which makes AURATON Tucana R achieve only one temperature during our absence. The holiday mode can last from a minimum of 1 hour and to a maximum of 99 days.

To activate the holiday mode:

If the selection is not confirmed, AURATON Tucana R will automatically switch to the holiday mode set after 10 seconds. Press the i button to exit the holiday mode.

Setting the anti-freeze temperature program

U

In AURATON Tucana R, you can set the anti-freeze temperature in the range of 0 °C to 10 °C but it cannot be deactivated (the factory setting of the anti-freeze temperature is 7 °C).

In the case of a prolonged period of absence, it is possible to activate the anti-freeze temperature mode. It allows to avoid unpleasant consequences of the freezing of water in the heating system by automatically setting the temperature in the range of 0 °C to 10 °C. To set up the anti-freeze program, simply select program 0 on the desired day of the week.

Heating device operating time meter

AURATON Tucana R has a function of measuring the operating time of the heating device. It is activated by pressing and holding the i button for 5 seconds. For 10 seconds, the thermostat display will show the operating time of the heating device since the last reset of the device.

Turning off the relay temporarily

After the heating season, to avoid accidental switching on of the heating device, you can turn off the relay in AURATON Fornax.

Pressing and holding the : i ; buttons simultaneously for 5 seconds will turn off the relay (a minimum temperature of 4 °C will be maintained) and all display elements except the current temperature, time and day of the week will fade out.
To restore all the Tucana AURATON functions, press and hold the : and ; buttons again for 5 seconds.

Pairing

the weekly, wireless thermostat (transmitter) AURATON Tucana R with the wireless heating device controller (receiver) AURATON Fornax.

After connecting to the mains, switch the receiver on by briefly pressing the power button (F). When the device is switched on, the green power diode lights up and there is an audible single sound signal. To switch off the AURATON Fornax e.g. outside the heating season, hold down the power button for 3 seconds until there is an audible double sound signal, and the green power diode switches off, which means that the heating device has also been switched off.

1. To initiate the pairing of AURATON Tucana R (transmitter) with AURATON Fornax, press the right pairing button (D) –– a single sound signal on the AURATON Fornax receiver, and hold it for at least 3 seconds, until the LED diode starts blinking green (double sound signal), then release the button.
   The AURATON Fornax receiver will wait 120 seconds for pairing. After this time elapses, it will automatically return to normal operation.
2. Press the h pbutton on AURATON Tucana R (transmitter) for 5 seconds until the broadcast symbol (=) lights up on the display. Release the button – AURATON Tucana R transmits the pairing signal for 5 seconds.
3. Successful completion of pairing is signalled when the green LED diode on the AURATON Fornax receiver is no longer blinking, a single sound signal is heard, and the receiver returns to normal operation.

If there is a pairing error, please repeat steps 1 and 2. In case of further errors, unpair the device by RESETTING the AURATON Fornax receiver, see “RESET – Unpairing a device paired with AURATON Fornax – wireless heating or air-conditioning device controller (receiver)” and trying to pair the devices again.

Signalling the working status and data package reception

Each reception of radio transmission from a paired device is signalled by the AURATON Fornax receiver by a temporary alternating colour change of the LED diodes. When the relay is turned on, the LED diode is red and when the relay is turned off, the LED diode is green.

Unpairing the weekly, wireless thermostat AURATON Tucana R from AURATON Fornax

1. The unpairing of AURATON Tucana R (the transmitter) from the AURATON Fornax receiver is initiated by pressing the left unpairing button (E) on the receiver and holding it for at least 3 seconds until the LED starts blinking red, then release the button. The sound signalling works in the same way as during pairing, i.e. pressing the button is signalled by a short sound followed by a double short sound signal after 3 seconds.
   The AURATON Fornax receiver will wait for unpairing from the device for 120 seconds. After this period, it will automatically return to its normal operation.
2. Press and hold the h button on the AURATON Tucana R device (transmitter) for 5 seconds until the broadcast symbol (=) appears on the display. Release the button.
3. Successful completion of unpairing is signalled when the red LED diode on the AURATON Fornax receiver is no longer blinking, a single sound signal is heard, and the receiver returns to normal operation.

If there is an unpairing error, please repeat steps 1 and 2. In case of further errors, unpair the paired device, see “RESET – Unpairing a device paired with AURATON Fornax – wireless heating or air-conditioning device controller (receiver)”.

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

In order to unpair a device (e.g. a thermostat) paired with AURATON Fornax, simultaneously press and hold both pairing and unpairing buttons (D and E) for at least 5 seconds, until the LED diode starts to alternate blinking green – red. Then release both buttons. Sound signals: pressing the button, a short sound signal – after 5 seconds, a double short sound signal.
Successful completion of device unpairing is signalled after about 2 seconds, when the signalling changes to green, and then fades out for a short time.

The RESET function of AURATON Tucana R

Pressing the RESET button (.) clears the time and day and restarts AURATON Tucana R.

The MASTER RESET function of AURATON Tucana R

The MASTER RESET function restores factory settings. It is activated by pressing the i and RESET (.) RESET buttons simultaneously.

Configuration settings

Configuration settings are set one after another:

To enter the edit mode of the configuration settings, hold the b and c buttons simultaneously for 5 seconds until the settings menu is displayed.

Changing the backlight colour

Changes in hysteresis

The hysteresis change mode is signaled by a flashing HI. Use the bc buttons to set the desired hysteresis.
HI 2 – ±0.2 °C (preset),
HI 4 – ±0.4 °C,
HI P – PWM operating mode (see chapter “PWM operating mode”).

Confirm your choice by pressing the i AURATON Tucana R will proceed to change the next parameter.

Offset change

The offset function allows you to calibrate the temperature indications with a tolerance of ±3 °C. For example, AURATON Tucana R indicates that the room temperature is 23 °C and a standard wall thermometer hanging next to it indicates 24 °C. Changing the offset by +1 degree will make AURATON Tucana R indicate the same temperatures as the wall thermometer.

Clock calibration

This function is used to correct the clock indications in case of any deviations. If the clock is working incorrectly within a week, the extent of incorrect clock indications should be determined. This value should be entered in AURATON Tucana R in the form of seconds.

Example 1:
After a week of operation, AURATON Tucana R shows time accelerated by 1 minute and 20 seconds (60 + 20 = 80). In this case you should slow down the clock by setting C -80.

Example 2:
After a week of operation, the clock in AURATON Tucana R is 2 minutes slow (2 x 60 = 120). In this case you should speed up the clock by setting C 120.

PWM operating mode

 (Pulse-Width Modulation)

By changing the hysteresis settings (chapter “Configuration settings”), you can turn on the PWM operating mode. In this mode, AURATON Tucana R cyclically turns on the heating device in order to minimize temperature fluctuations. AURATON Tucana R checks temperature rise times and temperature drop times.

Knowing these values makes AURATON Tucana R turn on and off the heating device in appropriate cycles to maintain the temperature to the set value as close as possible.

Special cases

• When 3 consecutive transmissions are lost (after 15 minutes), AURATON Tucana R R (transmitter) will signal a malfunction on the AURATON Fornax receiver (the LED diode will alternate blinking red and green). Until the problem is resolved, the receiver will enter the stored on/off cycle from the last 24 hours.
• When the signal from AURATON Tucana R R returns, the error is cleared and the AURATON Fornax receiver returns to normal operation.

Additional information and comments

• AURATON Tucana R R (transmitter) must be installed at least 1 metre away from the receiver (too strong a signal from the transmitter may cause interference).
• At least 30 seconds must elapse between switching the relay off and on.
• Data from AURATON Tucana R R (transmitter) is transmitted to the AURATON Fornax receiver every time the ambient temperature changes by 0.2 °C. If the temperature does not change, AURATON Tucana R R transmits control data every 5 minutes (this is signalled by a blinking orange diode on the receiver).
• In the event of a power failure, the AURATON Fornax receiver will switch off. After power is restored, the heating device will automatically switch on, and the AURATON Fornax receiver will wait for a signal from the paired AURATON Tucana R R (transmitter) no longer than 5 minutes after power is restored. After receiving the signal, the AURATON Fornax receiver will return to normal operation.
• Placing the AURATON Fornax receiver in a metal housing (e.g. mounting box, metal housing of a furnace) will cause interference with the operation of AURATON Tucana R R.
