In larger buildings, as well as many other hydronic heating systems, it’s common practice to start the heating according to the outdoor temperature. At least in Europe.
I would like to add two things, the first is a time delay to turn on heating, or cooling for that matter. The second is a second set point where the thermostat turns on regardless of delay. A nice feature to have would be an integration of temperature deviation and time, like the I portion of a PID regulator, where the thermostat turns on when this reaches a certain value. This is also common in hydronic heating systems, primarily with on/off heat pumps.
