Thank you scalz,
will start my project in this case.

Hello All,
I am beginner and want to start with heating scheme. I have read many articles here and ready for try (I hope ).
Want to manage my heating system in the house (5 heating circuits with water).
Will buy a collector, room thermostats and actuators for each circuit.
Could you please review my schema and give a feedback if my understanding is wrong?
Thank you.
