For heat pumps it may not be wise to set back very much. If the gap
between "set" and "actual" gets too large it may kick on resistance
heat, depending on the ambient temp and intelligence of the controls.
Resistance heat is much more expensive per unit of heat than the heat
pump. If you're in a cold climate your opportunity to save on heat
may be limited.
