It needs a little bit of experimentation to set the profile the first
time - basically waiting for colder days and seeing if the system still
heats the place comfortably and quickly enough. If it doesn't, then you
just tweak it up to a steeper curve. It also helps if you have
appropriate rad sizes for the rooms, and the system is balanced.

Balanced?

I have always assumed there was no need to balance a system, where TRV's
are installed.

if TRVs can be set to reliably keep a room at, say 20 degrees, then it
doesn't

but if they can't, then it does

I'm about to find out if the first line is true, because it is clear than
my new systems is not balanced.

As it is currently set, the lounge is like a sauna, and the rest of the
house still cool.

I actually don't have a problem with the latter, it's the former that's
the issue

Where is the room stat?

in the hall way

That is the big problem with TRVs, you have to have the system run
whenever any rad wants heat and its difficult to impossible with only one
room stat.

works OK in my current house which is, presumably, balanced properly
