By integrating the Damper Tree you can connect your HVAC System to your Loxone Miniserver. Get a fully-fledged self-learning and easy to use heating and cooling control. It gives you the perfect temperature throughout the day – while keeping the energy bills low.



The installation of this device must be carried out by a qualified individual. When installed, the device must follow building regulations for electrical and fire safety. If the device is not installed according to manufacturer’s guidelines, the warranty of the device may be affected. Install the damper between the ventilation ducts and fix them with a foil tape that is certified to in that kind of installation. Connect SELV and Tree communication to the Damper Tree. Once connected power up the device and configure it using our simple to use Loxone Config.


The Damper Tree performs calibration after being learned into the system.

To commission, the damper tree connects the 24V power (orange/orange-white) and the Tree (green/green-white).

There are also the following outputs for troubleshooting:

  • Online Status
  • Damper stuck


The analog output of the actuator can be linked directly to the out put ‘AQh & ACc’ of the HVAC Room controller block. The HVAC Room controller block is not available in the official release at the moment. Please get in touch with us if you would like to get the beta version of our function block.  ([email protected]).

The Damper can open or close completely for test purposes. To perform this test, right click on the Damper in the Periphery. Here, you can now carry out the device Start Device Test (= fully open Damper),  Stop Device Test (= fully close Damper) and obtain the travel details (Re-calibrate Device).


To ensure that the Damper knows the exact movement they must run a calibration procedure. This is done automatically when you first learn the Damper in so we recommend you learn in and power up your Damper for the first time once installed.
