No. As said it’s just ZWave relays connected to valves (these) and ZWave temperature sensors, although you can use any OH compatible device as relays and sensors or even combine them from multiple technologies.
Either way, key is to have a comprehensive concept to properly cooperate with your existing heating controller. Any heating setup is always a pretty individual thing and you need to program your own OH rules.
Check out this post for a software framework.
Anyway, this is getting off-topic. Open a new thread on that if you have questions to the community.
