Been meaning to post this and got busy. Posting what I figured out with above help, research, and trial and error. Now I have place to go if I need a reminder
and hopefully helps others out in the future.
As M&M stated the bottom bottom Vent controls do nothing.
And as DutchmenSport pointed out, the heat pump only work to about 45 degrees.
If I have heat source set on GAS and fan on auto, BOTH the furnace and the heat pump run.
I will use this setting when low temps are 45-55.
If I heat source set on ELECTRIC and fan on auto, BOTH the furnace and the heat pump still run. However, the heat pump is the primary; the furnace only turns on when it is needed due to temperature drop well below set temperature; seems like about 10 degrees.
I will use this setting when low temps are about 55 or higher.
If I heat source set on GAS and fan on off, ONLY the furnace runs.
I will use this setting when low temps are below 45.
