Choosing the right location for AURATON Tucana

The correct operation of AURATON Tucana 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 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 to possible vibrations may also cause problems with proper operation of the device.

Connecting the wires to AURATON Tucana

The wire clips are located on the back of AURATON Tucana. It is a typical single-pole double-throw relay. In most cases, the NC clip is not used.

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 – weekly, wired thermostat

To mount AURATON Tucana 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 through the screw head and slide to the right (note the keyhole-like opening on the rear cover of AURATON Tucana).

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.

Deactivating the anti-freeze temperature

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

Factory programs

In order for AURATON Tucana 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

To program AURATON Tucana, set the day temperature intervals for individual days of the week. At other time, night temperature will be set.

Sample AURATON Tucana setting from Monday to Sunday. Outside the intervals programmed, the night temperature will be set.

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

Program selection

To set a program:

1. Press the h button. The program number segment will start flashing.

   

2. Press the l button and then use the bc or l buttons to select the day of the week on which the program is to be executed.

   

3. Press the h button several times and select the desired program number. Programs 0-2 are factory ones, programs 3-9 can be modified by the user.

   

4. Confirm the selection with the i button.
5. Return to step 1 and repeat the procedure for the next day of the week. When each day of the week has been assigned an appropriate program, we can finish the programming.

Modifying user programs

To set a program:

1. Press the h button. The program number segment will start flashing.

   

2. Press the l button and then use the bc or l buttons to select the day of the week on which the program is to 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 ; :) button.

   

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 device, we can use the holiday mode, which makes AURATON Tucana 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 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, you can set the anti-freeze temperature in the range of 0°C to 10°C (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 program 0 on the desired day of the week.

Heating device operating time meter

AURATON Tucana 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 Tucana.

Pressing and holding the : and ; 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 AURATON Tucana functions, press and hold the : and ; buttons again for 5 seconds.

The RESET function of AURATON Tucana

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

The MASTER RESET function of AURATON Tucana

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 will proceed to change the next parameter.

Changes in the delay

The delay prevents too frequent activation of the actuator, e.g. due to temporary drafts (caused by opening the window, etc.).

Offset change

The offset function allows you to calibrate the temperature indications with a tolerance of ± 3°C. For example, AURATON Tucana 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 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 in the form of seconds.

Example 1:
After a week of operation, AURATON Tucana 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 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 cyclically turns on the heating device in order to minimize temperature fluctuations. AURATON Tucana checks temperature rise times and temperature drop times.

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