The message
from "Mr Sandman" contains these words:


I have the same problems with my wife. If im away for the day, i come back
to a house with all the TRVs turned up full . She still cant grasp why the
kitchen rad is cool when the living room rad is hot!

Women in general haven't a clue what a thermostat is. But all our TRVs
in this house, have upper and lower limit stops which can be set to
prevent the rad being turned down too low or up too high. Or can be
used to lock the head at any point in its range. Problem solved as far
as the TRVs are concerned. The open windows are another story and I
haven't got the answer to that one. Yet.
