In most applications it saves energy to turn it down. However if you
have a heat pump, and to get the house warmed up again it goes to
emergency heat, then it can cost more. If you can turn off the
emergency heat and wait a long time for the heat pump to catch up, then
you will save energy. The worst case is electric emergency heat, gas
emergency heat may or may not save money depending on the price and
efficiency of the furnace.

The above is the CORRECT answer... congratulations!!

Hi,
Many programmable thermostats are intelligent. It learns when to start
to bring up the temp. to normal setting ahead of time. So by the time
people come back home/ofice after et back period it's at proper temp.
