outdoor reset:

“It changes the supply temperature in response to an ANTICIPATED change in demand indoors. I say "anticipated" because your house shell and insulation introduce a lag in demand.

If your system is digitally controlled it will try to keep calls for heat as long and as infrequent as possible regardless of the temp outside. The more closely your reset curve matches the actual loss, the longer and less frequent the calls for heat.

If your system is proportionally controlled (IE: TRV’s)
it will try to keep flow through the system as consistent as possible by ensuring that the temperature of the circulating water closely matches the heat being lost by the structure.”
