You can regulate the flow on an Mira shower. What are you on about?

We might be talking about different models. She has a single control.
Anti-clockwise is off. Then rotating clockwise slightly turns it on.
Turning
it further adjusts the temperature. It said Mira 415 on the box, but there
might be multiple versions of this mixer.

The 415 has limited flow control. The idea is to get a minimum flow so that
pressure valves can fully open. ON many combi's this is not the case and
just a trickle of water will be enough to fire the burner.
