There are also smart thermostats that can be controlled remotely over Wi-Fi. Some thermostats create schedules and automatically adjust to your needs when you're away. To learn more about selecting a programmable thermostat, see Selecting the Right Thermostat for Your Home.
Caution
Follow the manufacturer's instructions for how to change a thermostat safely. Check to see if you need a permit, and observe applicable building and electrical codes. Contact a licensed electrician if you have any doubts or questions about the connections or if your home's wiring doesn't appear compatible with the changes you're making.
