Is it now a reg to fit a room stat with combi boilers

What happens when the boiler shuts down, the trvs open and there's no stat installed to call for more heat? With the boiler shut down there is no flow to kick it back on - unless the pump is spinning wildly against a closed circuit.
My CMZone and CM67 stats are within half a degree and have been for over 2 years.
You have to admit though, it is a s**t idea
Especially when you consider how unreliable trvs are -
and some don't actually turn off completely either.

I think their is a control circuit which pulses the pump on/off periodically to check for flow though I stand to be corrected on that.
Standard wall stats are not very accurate anyway and I am sure a lot of people just turn them up high anyway.
With the flow switch each individual TRV will have control over the boiler interlock and has the added advantage of proportional temperature control over each individual room space temp and not just an on/off as dictated by an inaccurate room stat in some dodgy location adjusted to an even more dodgy setting by the user.
IMO.
