First job was set lock shield valves, better but not right, next was turn down all the TRV then back up bit at a time until room some where near, on an over cast day not bad, but clear sky was a problem the bay windows down stairs catch the sun, up-stairs near enough, but down stairs was a nightmare, so started a string of attempts to get the two rooms some where near, the pair of eTRV's helped.
However your comments about putting a thermostat outside even if in error did go through my mind, after some experiments I realised TRV's gradually open and close and in turn by what ever method control the boiler. But it was the turning off the boiler when no longer needed which is the problem, in hind sight I should have gone for EvoHome, however now I have the hub and two Energenie eTRV's not inclined to bin them and start again.
So I have tried a compromise with standard TRV and wall thermostat both in hall, and it does to an extent work. However if I can understand how the boiler works, maybe then I can better work out how to control boiler? What is left to sort out is how to drop temperature at night and raise it again during the day.
