Manually would be fine if you don't mind. I don't think you'd notice the temperature that frequently to need the high stage.
You can get an outdoor thermostat to turn the second stage switch on when the weather gets down to a certain value. Outdoor thermostats are used on electric heat stages of heat pumps and also humidifiers.
