Smart AC - What is "Auto"?

I recently bought the Smart AC Controller V3+ and everything seems to be working just fine. However I can't figure one thing out - the Auto mode. In the Heat and Cool mode I can set the desired temperature but I can't find that setting in Auto. So, what does this setting do?

    Hello Blue_Suede,

    This depends on the AC's Auto mode behavior, is not controlled by us.

    Best regards,


  • Ah, OK. I will just have to experiment a little and see what happens.

    Thank you for your answer, Germán!
  • I saw a comment on this board, and my testing confirms the same, that setting the mode to Auto makes it heat to 25 degrees. I don't know if it would cool to 25 degrees if the starting temperature was higher.

    This isn't working as the "Auto" mode built into the air conditioning unit, which keeps keeps the unit heating or cooling to the specified temperature.

    It would be helpful to know from Tado if the 25 degrees functionality is the currently implemented functionality and working as intended.

    Any update on this? In my auto mode (Fujitsu ac unit) you can set the temperature when in "Auto" mode and the unit will then either cool or heat to the desired temperature.

    As has been said I currently cannot set a temperature in "Auto" mode just as you would in cool or heat mode.

    "Auto" mode is the most efficient of modes i.e. only cools or heats when needed so please Tado support this by adding the ability to set the temperature (and fan speed) for this mode just as you've done for cooling and heating.
