.. formulated the question :
"Set the 'cool' temp to something like 85 degrees)".
"Push the switch to the "heat" position"

Which one should I do or should I do both?

Since you are too stupid to have a name how could we expect you to R T
F M.

Please try and understand your own problem before asking stupid
questions.

If you do not know, RTFM means READ THE Fantastic (F******) Manual :-Z
