1- when you shut down at night to 57, it takes 3 hours or more before
the
temp hits 57 but in the morning when you bring it up, it rewarms pretty

in 15 mins or less.

I'm not getting this, can you explain further?

It takes a certain amount of time to reheat back to your 65 in the
morning. It takes a certain time to drop back to 57 when you cut the heat
back.

Unless we know how long those 2 are, no one can answer your question as it
depends on the insulation and heating efficiency of your home.

The best any can do with what was posted is ask how long it takes to drop
to 57, and how long it takes to heat back to 65.


What difference does it make how long it takes to drop to 57? The furnace is
not working at all at that time. Only when the temp is reset to 65 the next
morning does the furnace come on continuously till the temperature in the
house climbs to 65.
