No no guys, it's way easier. You have thermostat now that is a bimettalic one with a knob. The old style. Just replace it with a new one that is a digital set back thermostat made for line voltage. I did this replacement in my kid's room and they work great. No relays, or wiring anything in series, no seperate timers, no new wiring. Just need to replace the old cheapo stat with a modern technology stat. Modern stats such as this can do just about anything you want them to and are available at regular hardware stores, I bought mine at a chain called McLendons.
