It's not that uncommon for a manufacturer to require a certified technician trained for their system if you want a warranty. Otherwise some schmuck can try and do the install themself and then complain because it isn't working right.
Just replaced a delta faucet insert that I was tooooooo lazy to bother with because it had only dribbled out the stem when the faucet was on.
Dumbass contractor put the spring between the seal and the insert instead of putting the seal between the insert and the spring. Can't believe it worked as well as it did.

I replaced a couple of lights in the house. Stuff not hooked up right. Spent a few hours taking every light switch and light apart. Loose screws on half.
