Opening angle stop AVENTOS HF

Which opening angle stops are suitable for use with AVENTOS HF and how are they installed?

Kitchen with Blum AVENTOS HFHave you ever experienced a situation where fronts with an AVENTOS HF lift system touch the ceiling when it is fully open? We offer opening angle stops for just such situations as the front or the ceiling may become damaged when the two touch. However, fronts can also collide with furniture structures above, such as cornices.





For applications in which an opening angle stop is required, we offer two different items. Opening angle stop 20F7051 (dark grey) to limit the opening angle to 104° and 20F7011 (dust grey) to limit the opening angle to 83°.

You can work out if opening angle stops are required, and if so which, during the construction phase. You can use the following formula to help you with this:

This picture shows the calculation chart for the AVENTOS HF opening angle stop

For example, for a front height top (FH) of 360 mm, you will not need an opening angle stop where the space requirement above (Y) is 210 mm. If the space requirement above (Y) is only 150 mm, you will need the 104° opening angle stop.

Note: with the opening angle stop 20F7011, the fronts no longer protrude beyond the cabinet, so the cabinet can be planned up to the ceiling.


How can I install the opening angle stop quickly and easily?

In principle, if you need to limit an opening angle, you should use an opening angle stop for each lift mechanism.

You do not need to disassemble the fronts for this, but removing the cover caps does make assembly easier. Close the fronts by approx. 45° and press the opening angle stop into the now-free opening until it clicks into place.

    Hi Patrick,

    The servo system required a reference run (this is an Avento HF system). I followed the instructions for a reference run (press the reset button), the orange LED started flashing rapidly, I closed the door manually and pressed the bottom of the door (by hand) so that the system can start the reference run. However, after waiting for about two minutes, the reference run did not start.
    I can see that the orange light flashes (but not rapidly) at around 1s intervals…
    I pressed again the Reset button (the one above the orange LED), kept pressed for 30s, still the behaviour (orange light flashes at 1s intervals). I repeated the above but kept the Reset switch for 60s -> same behaviour.
    I turned off the fuse that goes to the power supply of the Avento transformer, left it off for about 1hr -> when turning the fuse back On, I got the same behaviour (ie, the orange LED flashes continuously at 1s intervals).
    I am out of options now; I did search on line (and this blog) but cannot find anything. Can you please help?

      Hi Edmond,
      the continuous flashing of the orange LED is a sign that you have successfully reset the “motion” of AVENTOS and accordingly, a new reference run is required.
      As AVENTOS does NOT start the reference run after pushing on the front I suspect that the wireless switches are not synchronised with the AVENTOS SERVO-DRIVE unit.
      Perhaps it is best to push the “reset wireless” for a couple of seconds until the green LED flashes. Then follow the instructions in the following video (after min. 3:18) to synchronise the switches with the SERVO-DRIVE unit:

      As soon as the switches have been synced successfully, close the front, and after pushing it one more time, the reference run (2x opening and closing motion) will start.

      Kind regards

        Hi Matthias,

        I have done that as well: unfortunately I get the same behaviour (there are two wireless switches, one of each side of the cupboard, so that I had to follow the Reset procedure for each switch). What I haven’t done is to run the “Reset” procedure for just one switch, than to try the “reference run” and than to do the second switch (but I don’t think that will help). The LED flashes Orange (at 1s intervals) for 5 days now, and the servo doesn’t work. Help!

          Hi Edmond,
          I still suspect that the wireless switches and the SERVO-DRIVE unit are not connected, which is why the reference run won’t start upon pushing on the closed front.
          Another reason could be a weak battery in the switches.
          However, think it will be best if one of our local customer service representatives will contact you by phone to guide you through all the configuration steps.
          I’ll make sure somebody will get back to you ASAP.
          Greetings from Austria
