I’ve recently been working on installing a Homematic thermostat for my heating system, and I must say, it’s been quite the learning experience! While I’ve managed to install 10 radiators without any issues, two of them have been giving me a bit of trouble. The thermostats in question are Oventrop Uni LD models, and I’m struggling to figure out the right adapter to use. The ones that came with the package didn’t work, and I’m not sure where to look next. 
I’ve tried everything from checking online forums to reaching out to local hardware stores, but nothing seems to be clicking. The worst part is, the heating system is running constantly, which is not only inefficient but also a bit unnerving. I really need to get this sorted out before the colder months set in!
Has anyone else encountered a similar issue with these thermostats? If so, I’d be incredibly grateful for any advice or recommendations on the right adapter to use. I’m hoping there’s a simple solution that I’m just overlooking. Let’s cross my fingers! 
In the meantime, I’ll keep experimenting and document my findings. If I figure it out, I’ll be sure to share the solution here. Until then, any tips or tricks would be a huge help!
