Ahoj, hello z čech.
I am using thermostatic valves from another manufacturer, with the same asks.
You can read my post here
I found the same thing with those switches.
The first is BOOST, it increases the heating for about 5 minutes.
The second is LOCK and locks the warhead.
I don’t know what the third one is for.
I don’t know what the binary input is for either.
But after integrating 5 warheads via ZHA into HA, there are some intricacies.
All 5 heads work fine, but the switches only work for me on the last integrated head.
First I integrated 2 heads. The switches worked on the other one. Then I added 3 more heads, and those switches only work on the last fifth one.
