Best Practice: Heating Control via KNX – Part 1 — 4 Comments

  1. A 20 A Switch Actuator is not the best way to control valve drives on/off. The klick/klack of the relays is for the user very disturbing. Therefore we propose, even in the case of simple on/off-functionality, an electronic switch actuator or a valve drive actuator.

  2. Hi Dieter,

    Thank you for your comment, I agree the electronic switch actuator or valve drive actuator are best for controlling valve drives. But as I have not specified what type of load these would be switching in the article I was using the 20 A switching actuator as an example of switching a large load the electronic actuator would not be rated to handle. As for the klick/klack sound this can not be avoided when switching a large current, best practice is to locate this device away from occupied areas.

  3. Hello,

    I am doing a project on climate control with KNX, it was. Very useful for, although, I read on that before quite a lot!

    I have a question: when do we need to use a heating actuator and can we connect a temperature controller directly to the drive (if it s supplied by KNX e.g.)?

    Thank you. Hope to get a reply, cause soon I should solve this problem with heating actuator!;)
