No. The heating curve essentially tells the controller how your property responds to different temperatures. That profile won't change with temperature, but the controller should know how to adjust the boiler according to temperature.
It's a setting which you or the engineer set up, so the system has an idea of how to respond to varying temperature demands. Basically - Your boiler checks the outdoor temperature, indoor temperature, desired temperature, plus the heating curve, to calculate how much heat to generate. Set the figure too high and the boiler will heat the water more than necessary and waste gas, set it too low and it may take too long to hit your desired temperature.
Certainly worth noting the current setting so you can restore back to it and seeing how it works with a lower setting on a cold day.

thank you. I have vsmart which sorts it all out but noticed just lately it has come on at 100% for 30min then off for 1hr until temp drops below set point. It used to just tick over at 30-40% to maintain the temp and I wouldnt get a cold feeling.

It sounds as if it is over reacting, bunging much more heat out than necessary - try entering lower numbers for the heat curve.
What it should do is hit the spot precisely. If you turn the stat up, it should decide exactly how much heat it needs to output, to meet it exactly - no over or undershoot. As it nears the newly set temperature it should wind the output down gradually, then maybe continue burning at a minimum level, just enough to maintain your desired temperature.
Are you saying the Vsmart itself changed the setting, or you changed it?
Thanks, I didn't know it changed the actual numbers - I understood it only trimmed it internally. Must check mine..
[EDIT] You are correct, mine has changed itself too..

– You can use this function to activate an automatic heat-
ing curve.
If you have activated this function using the Yes setting, the
controller automatically adjusts the heating curve. The auto-
matic adjustment of the heating curve is performed in small
steps. Use the Heating curve function to adapt the heating
curve to the building so that the Adaptive heat. curve func-
tion still has to carry out the fine adjustment.
Always worth fiddling and reading up on the theory, to get the best out of it. Installers, even the best informed of them, can only guess how the system will actually perform in your particular environment.
Range setting of what?
