Just fitted TRV's to rads and wondering what is the correct procedure for
setting up. Do I open up TRV's and balance usuing valves on other end?? Any
help please. Thanks

Yep, that's it, if you don't balance the system the rads on the easier paths
will steal all the flow until their demand temperature is satisfied. Follow the
balancing procedure in the DIY faq with TRVs fully open, then set the
TRVs to your desired comfort setting and all will be well.
