Where can I find a Technical Reference and/or Installation manual?
Go to Tado.com/Start and pretend to be a professional installer. It will download a pdf file.
I was wondering the same thing - you can't get the install instructions until after you've purchased the product, but if you're trying to work out if you can install the product and it it will work with your setup, you're looking for the install instructions to educate you. :-/
tado.com/start gives a 404. And if you want to register as an installer there's far more info you need to add to get past that hurdle and maybe get to the info we want.
I find it troubling that this kind of basic support information is hidden!
Not sure why you cannot get tado.com/start,. The pdf files are there for download without giving any further info.
