Hi, thank you for choosing Just Answer, my name is ***** ***** I will help with your query today.

Unless this is a vented system it will need an engineer to commission this as its notifiable under building control.

To understand you correctly who sped' the valve and what are you struggling with in terms wiring in the zone to work with the stat?
