Summarize the following:
Keep your thermostat at a consistent and comfortable temperature. A conventional heating system usually requires you to turn the thermostat down while you sleep or while you're away from your home. By increasing the temperature drastically, you force your heat pump to work harder. It could also make a secondary heating system run and burn more energy. The heat pump will not heat the area faster if you turn up the thermostat. Your heat pump will not have enough power to keep your home at a comfortable temperature. The setting will either say "auxiliary" or "emergency" heat. Your energy efficiency will decrease the more you run an auxiliary unit.
Set your heat pump to "heat" at 68F (20C) for the highest efficiency. Avoid increasing the thermostat more than 2 degrees at a time. Turn on a backup heat unit if outside temperatures are below 35F (2C).
