You probably just need to replace the battery. The normal way these
things work is that if you manually change the temperature setting (and
don't hit HOLD), it stays that way until the next programmed change. If
you manually change and then press HOLD, it stays that way
indefinitely. Pressing the reset button will reset the programming,
which might be set as a default to something like 60 during week days,
68 in the morning and evenings, 68 on weekend days. And it sounds like
that is what you are living with.

If your battery is dead, it probably forgets everything after 5 or 10
minutes, including your manual change. Since you have been struggling
with this for 4 years (!!), I am guessing that your battery is at least
that old. It's usually just a single AA battery in the thermostat
itself.

Thanks for you help. I changed the batteries a couple months ago, and
they display still lights so they seem ok. But I have never used that
hold button, so that might be the whole problem. You could be right
about those settings, because I dont recall ever setting anything to
60. I went lower than that when I was at work, to save fuel, and
higher when I planned to be home. Yeah, I know I put this off way too
long. I am good at procrastinating with things like that. I didnt
have a manual so it always seemed like too much hassle to screw with.
I almost bought a new thermostat (regular one) not too long ago, but
decided to try to reset mine (which I never did).
I guess I got to be too sick to work outside to make me do these
little jobs in the house....
