Note for Heat Pump Owners 
When a heat pump is in its heating mode, setting back a conventional heat pump thermostat can cause the unit to operate inefficiently, thereby canceling out any savings achieved by lowering the temperature setting.  Maintaining a moderate setting is the most cost-effective practice.  Recently, however, some companies have begun selling specially designed setback thermostats for heat pumps, which make setting back the thermostat cost effective.  In its cooling mode, the heat pump operates like an air conditioner; therefore, manually turning up the thermostat will save you money.
