AURATON 2YA mount

weekly, wired temperature controller

Remove the cover as shown below.
Screw the rear part of the AURATON 2YA housing to a standard Ø 60 mm electrical box using the screws included in the kit.
Put the casing on.

First start-up

Once the power is connected correctly, all segments will appear on the LED display for one second.

Then the controller will wait for the first start-up or time setting (off mode)

Setting the clock and day of the week

To set the clock, the controller must be in off mode.

Press and hold ( Ê ) for 3-5 seconds. The minutes segment will flash on the display.

the function buttons ( Á Â ) to set the desired minute and confirm with the button ( Ê ).

the function buttons ( Á Â ) to set the correct value in the hour segment and confirm again with the button ( Ê )

The day of the week symbol will flash in the upper left corner of the display. Use the function buttons ( Á Â ) to set the desired day of the week and confirm your selection with the ( Ê ) button.

NOTE:
When programming any functions, not pressing any button for 10 seconds is equivalent to confirming the entered data.

NOTE:
The first press of any function button always displays full information, and only then does the button function start.

Programming

NOTE:
Before starting programming, set one of the three program operation schedules in the controller menu.

Setting the operating schedule of the controller programs: see the Advanced Settings .

The AURATON 2YA can store up to six programs and work in three schedules. This allows for exceptionally precise planning of the building's temperature depending on the time of day.

Schedule 0 (5 + 2 days; factory setting) – allows you to set programs for Monday through Friday and Saturday and Sunday.
Schedule 1 (6 + 1 day) – allows you to set programs for Monday through Saturday and Sunday separately.
Schedule 2 (7 days) – sets six programs for the entire week.

Sample factory programs

Ä 1	incentive	from 6:00	20 °C
Ä 2	away from home	from 8:00	15 °C
Ä 3	returning home	from 11:30	15 °C
Ä 4	away from home	from 1:30 p.m.	15 °C
Ä 5	returning home	from 5:00 p.m.	22 °C
Ä 6	night	from 10:00 p.m.	15 °C

To start programming you need to:

NOTE:
The controller must be turned on

ë button for approximately 5 seconds until the hour segment flashes on the display.

Use the ( Á Â ë ) button again

Use the ( Á Â ) buttons to select the minute of the program start and then move on to the temperature setting by pressing the ( ë ) button.

Use the ( Á Â ) buttons to select the program temperature and then move on to setting the next program by pressing the ( ë ) button.

Set the next programs, up to 6, according to the principle above.
This is how we set the programs for Monday through Friday (5 days). To set the next 6 programs for Saturday and Sunday (2 days), proceed in the same way as for weekdays. The display will show the number 2, indicating Saturday and Sunday.

NOTE:
After completing the program settings, the controller will automatically save the entered settings and resume normal operation.

NOTE:
When setting the 2nd work schedule (2:7 days), you only need to set 6 programs that will be executed every day for the entire week.

Manual control

If for any reason you want to interrupt automatic operation at a given moment and change the maintained temperature, you can do it manually.

Use the ( ë ) button to select manual mode, which is indicated on the display by the ( Ö ) symbol. Then, ÁÂ to select the desired value, which will be automatically saved. To return to the program (automatic operation), use the ( ë Ü ) symbol will then be visible on the display

You can also activate a temporary manual mode that maintains the manual temperature until the next program change.

To activate temporary manual mode, press the ( Á or Â ) button while in automatic mode, then use the same buttons to set the desired value.
To cancel this mode, press the ( ë ) button until the ( Ü ) symbol appears on the display.

Vacation mode

If you'd like to suspend programs for an extended period, you can use vacation mode. While this option is active, the AURATON 2YA only maintains the "vacation temperature."
Vacation mode can be used for a maximum of 30 days.

To activate the holiday mode (controller turned on):

Ê button for approximately 5 seconds until the display shows flashing OFF .

Use the ( Á Â ) buttons to change the text to ON , then confirm with the ( Ê ) button.

Select the appropriate number of days using the ( Á Â Ê ) button.

Then use the ( Á Â ) buttons to set the desired temperature.

Confirm everything with the ( Ê ) button.

While vacation mode is in effect, the ( õ ) symbol will be displayed on the screen.
To end vacation mode more quickly, press the ( Ê ) button for approximately 5 seconds and use the ( Á Â ) buttons to change the text to OFF . Then confirm your selection with the ( Ê ) button.

NOTE:
When programming any functions, not pressing any button for 10 seconds is equivalent to confirming the entered data.

NOTE:
The optimal comfort temperature is 18℃ – 22℃.
