Install thermostats with a night setback

A night-setback thermostat saves energy by automatically adjusting indoor temperatures.
Generally easier to use than more fully-programmable thermostats, night-setback thermostats curb energy use by cutting back on heating or cooling while occupants are asleep, or the house is unoccupied. Then they normalize temperatures when the house is occupied. Night-setback thermostats save more on heating than on cooling.
