Can you see the flow at the manifold after all...?
Yes, the OP should check that. The flow must go to zero when the RTR is turned off or to minimum at 22 or 23 degrees in the room (you can hear the quiet clicking when turning the dial if the switching threshold is undershot).
If that doesn't happen, there is something wrong electrically and the flow temperature doesn't matter for the time being. The heating cannot be properly adjusted anyway if not all heating circuits can be operated correctly. So definitely open the manifold first and test all RTRs one by one.
