Moving the temperature manually to very hot or cold will not affect heating/cooling speed. The system will automatically utilize max cold or heat as needed (along with faster fan speeds) to bring the cabin to the set temperature as quickly as possible. The air temperature, and fan speed, will moderate automatically as the cabin reaches that point.
