NIBE Heating Curves
Let's start with the most important thing. My charts of heat curves for NIBE heat pumps are the main reason people visit my website. Likely you as well.
The typical user manual that comes with your NIBE heat pump these days contains an oversimplified description of how to adjust the room temperature. For instance, it assumes that you have installed an indoor room sensor and only instructs you on how to set the desired target temperature by adjusting the number of degrees in Celsius or Fahrenheit. Totally worthless.
If you're looking for more advanced settings for your heating curve, you're simply referred to your installer.
Many installations, including my own, lack indoor room sensors and are controlled solely by an outdoor sensor. There are several reasons why this might be a better solution, but I'll leave that discussion for now and focus on the heating curves.
Heating Curve Charts
Here, you can download two different heating curve charts that I've created. One is for the typical range of a normal house in northern Sweden, and the other is a more extensive one with many more combinations. The larger curve is suitable for homes with floor heating and for houses with basements, for example.

A Humorous Bio
A long time ago in a galaxy far, far away... on the misty planet of Dagobah, I was first powered on.
My formative years among the swampy wetlands gave me a unique perspective on binary codes: they're not unlike deciphering the difference between a snake and a vine in the marshes.
With an innate talent for 0s and 1s, I soon found myself relocating to the Coruscant, where I landed a position at the IT department of the Galactic Empire. As luck would have it, I was stationed directly under Darth Sidious. (Honestly, between you and me, he isn't so much evil as he is just really frustrated with the constantly failing Wi-Fi on the Death Star.)
When I'm not busy rerouting complaints about the Empire's firewall (that one time it blocked 'Wookieepedia' was a massive PR blunder) or trying to convince Lord Vader that 'force-quitting' apps doesn't require actual use of the Force, you can find me indulging in my pastimes. These range from lightsaber dueling with colleagues on casual Fridays, stargazing (quite literally), and running the Death Star's only podcast: "Dark Side Tech Talks."
In the Empire, most know me as Erik Nyström (they're not very creative with names). But among friends, I go by "mx". So if you ever find yourself at the Death Star and need a quick software patch or just a fun chat about the newest holo-series, you know who to call!
How I Compute
Priorities and views
I prefer and primarily use Linux. I don't have a favorite Linux distro and suggest you go with one that suits your preferences. Mostly I use Fedora.
There are plenty of others who can offer better practical reviews and comparisons than I can. Honestly, I'm not in a position to judge distros based on practical criteria since I haven't tried them all. Testing each one would take a lot of time, and I have other, more productive things to focus on.
I’m all about working efficiently and minimizing the gap between my thoughts and actions when using the computer.
I prefer using vim-style keybindings and often run programs in the terminal for the sake of simplicity. However, I’m not a fan of the whole "terminals are cooler or nerdier" meme—it's pretty cringey. Terminals are great for a lot of things but definitely not for everything.
Using old and weird hardware
I tend to need to use old and weird hardware. Maybe you need it too sometimes. These are my very short, personal reminders on how to get that up and running on Linux. Okay, I agree. Right now, it's less of a list and more of a guide for a specific PCMCIA card, but I have big ambitions, and that's what counts.

Linux interprets the PCMCIA card as a modem, and therefore a PPP connection can be used with the help of the program minicom.
