are there any programmable thermostats out there that you can

sometimes leave the house for odd hours at a time and I'd like to be
able to override 2 or 3 settings at a time without having to program
each quarter. I'd like to have one that allows me to override the
custom settings for 5 hours or 8 hours or 2 days if needed.

I like the Honeywell models. Some have a "skip next time
period" (keep it at the current setting) or "go to next time period"
and the hold feature as well. Some do not need battery backups either
unless power is lost for a long time.

The Honeywell LCD touch panel, think they are called VisionPro, have a
feature called vacation hold. It holds the set temp for X days,
which you can set. It also has adaptive recovery, which figures out
how soon to fire up the system for recovery. So, if you want it to
be 70 at 8am, you just set that and it will fire up the system at say
7:10AM. It learns the amount of time needed over a period of time.

I've never seen one with the feature that the OP wants. It would be
similar to the vacation hold on the Honeywell, but would have
increments of hours instead of days.

I'd also suggest the OP check his existing one real close, because he
says it doesn't have a hold feature. He has a programmable one and
I've never seen a prog one that doesn't have a hold.
