Lunos SC-FT control integration

Hey folks,

Has anyone managed to integrate the fan control system using the SC-FT or SC-RF? I’ve seen some posts about the UNI-FT (i.e. in combination with the eGO fans), but not about the SC-FT. I have both (UNI-FT in my bathroom with one eGO fan, and a couple of fans with the SC-FT for the rest of my apartment). I know that some folks managed to integrate the UNI-FT with a 0-10V board but it seems that this does not work with the SC-FT (or does it)?

I do not want to invest in yet another system by getting the Homee stuff (Brain Cube and EnOcean Cube). I already have Zigbee, WiFi, Thread enabled on my Home Assistant.

Hi

I’m the Tech Lead for the Norwegian distributor for Lunos and thought I’m might be able to help with some of your questions.
There are two ways to integrate Lunos with Home Assistant (and other systems);

  1. Via the Universal Controller (UNI-FT or UNI-RF) with a 2ch relay for example Fibaro Smart Implant
  2. Via Smart Comfort (SC-FT or SC-RF) with a 0-10V controller, for example Qubino Flush Dimmer 0-10V

Option 1 - With UNI-FT/UNI-RF you’ll need to connect the three wires (black, red and grey) to the relay. Black is common and red should be connected to channel 1 and grey to channel 2 on the relay. NB the channels can not have any voltage, they’re purely binary inputs.
When correctly connected you’ll have 4 different fan levels available. These levels are decided by turning the “wheel” on the controller to the number that indicates the different m3/h air exchange you want.
Ch 1 and 2 OFF = level 0 (off or lowest level depending on the position of the “wheel” on the controller)
Ch 1 ON and ch 2 OFF = level 1
Ch 1 OFF and ch 2 ON = level 2
Ch 1 and 2 ON = level 3

Grå=grey
Rød=red
Sort=black

Option 2; via SC-FT/SC-RF you’ll connect a 0-10V controller to the 0-10V input on the smart comfort. The wheel should NOT be in the position that says 0-10V, but rather the correct type of fan you want to control.
Connection should look like the picture in the following post (can only embed 1 picture pr post)

Then we get to programming. You can find the correct input values from the 0-10V controller to smart comfort in the picture below. As you can see the values are close to each other so I recommend measuring the voltage on the output from the 0-10V controller as there can be 0,1-0,2V (maybe even more) difference between input and output.
100% =10V, 50%=5V and so forth.

The values on the left side are with heat recovery while the right side are without heat recovery.

NB; you need to program the 0-10V controller with set values, non-dimmable.

Hope this helps

The SC-FT is the controller that usually a bunch of fans are connected to (while often the UNI-FT is used with the eGO in a bathroom and thus only one fan is connected to the UNI-FT). Does this change anything in your description?

The setup is exactly the same. Just remember to set the coding switch to the correct fan/ventilator :slight_smile:

Hi everyone,

Sorry to reopen the topic again.

In my house i got these combinations of
Lunos 5/SC-FT and Smart Control Panel.

Where can i find the 0-10v Pin which was mentioned before ?

Thanks in advance !

I’ve written an integration for Lunos fan control via 0-10V using the Monarco HAT with a Raspberry Pi 4B.
