TRVs and single room stat only run the system while that one room is too
cold. Once it heats up, the whole system stops, even if other rooms are
too cold. The whole system only runs or stops at the same times of day.

Timer/stat per room allows each room to have different times as well as
temperatures, runs while any room is too cold and shuts down boiler and
pump when there is no demand.


Do you happen to know of a way to have a timer and stat per room but
adjust centrally the temperatures - or even just adjust them all up or
down by the same amount? I ask as IMLE one advantage of TRVs and a
single room stat is that if the stat is set lower than usual then (with
a reasonably balanced system) the rooms with the TRVs also stabilise at
a lower temperature than the TRVs would maintain. It's useful for
people who have days when they want the house warm and days when they
want to the house very warm.
