    I have a cathedral ceiling. Do you have any roof models?

      Thanks for the question Mike,

      Lunos does not make any models that can be installed in a roof. They are only made for wall applications at this time. Greater flexibility of installation is coming down the line. So stay tuned for new products, like the Lunos Nexxt.

    When installing the Lunos ego unit are there any special requirements for installation?

      Hello Jimmy, we don’t yet have a video for the eGO yet. But installation is similar to the e2 installation you see above. There are some differences. We recommend you go to the eGO product page and download the instructions for full understanding: https://foursevenfive.com/product/lunos-e-go-room-ventilation/

    Thanks for the video. Question. Other than the gasket, what keeps the tube from falling out the wall – is it anchored to wall in any way?

      Hi Paul, Thanks for the question: yes, you would want some sort support. The units are not heavy, but some sort of blocking needs to be in place. Generally speaking, your sheathing along with a small amount of blocking between studs on the interior, should be all you need to hold it in place and keep it at the slight pitch to the outside that is required.

    Just to clarify, if I’m hooking up 2 pairs of ventilators, I;m going to insert both wires (one for each pair into the correct spots) into each of the little spring loaded terminals in the controller?

    Also, I’ve secured the outer tube, but what’s to keep the fan unit from moving around in the tube? Just friction to keep it there?

    Also, minor point on the video, but it looks like the guy is running 12 ga wire to the transformer. I tried but the 12 ga did not fit in the terminals, so I used 14. Obviously that’s even overkill but it was a momentary confusion. Maybe he had a different model of transformer.

      Hi Jim,

      Sounds like you are on the right track. You are correct that you insert both wires into one port for a 2 pair Lunos system. I’m sorry you had trouble with the 12 ga wire, we haven’t heard that issue before – you may want to give it another go, but if you have 14 ga in there already and it’s working well, you can go with that. You’re also correct about the fan unit: it’s friction fit in the tube. One of several reasons why Lunos can only be installed horizontally in a wall (never vertically). Let us know if there’s anything else we can do to help.

        Thanks for the reply. I tried again with the 12 ga wire and got it in. The trick is to start pushing it in and then turn the screw and that will draw it in.

    Me and my partner recently purchased the LUNOS e2, included was the Smart Comfort controller (type 5/SC-FT). In the installation manual it says that the controller can be installed in a “standard switch box”. I am an Electrician and in my experience there is no way this controller can be installed in anything considered standard. I would like to know what LUNOS recommends to install the controller in.

      Hello Andrew,

      Sorry for the troubles. Most customers use a set of standard US light switches to operate their LUNOS system, and have no problem with double- or triple-gang box. My guess is that the instructions are either referring to installation of those switches, or if you’re using installation instructions specific for the Smart Comfort controller – they are probably referencing a type of German switch box that is not available in the US. Our recommendation would likely be to use a triple-gang box, if you feel that is the appropriate size. Otherwise, please do give us a call at 800-995-6329 and we can go from there to help you with a proper install.

    We have both the e^2 and the eGO. We can wire multiple “sets” of fans he said…does that mean the controller for the e^2 and the eGO are the same? We would like to wire all three together…Is that possible please? I have looked and tried hard to contact Lunos about this.

    Thank you for your time

      The controller of the e2 and the eGo or the same. However, a controller only can be set to either control e2 fans or eGo fans – not both at the same time. So if using both e2 and eGo in a house, you will need at least 2 controllers (but these come included with your e2 and eGo orders).
