Existing Thermostat:

What additional information is needed in order to select an
appropriate programmable thermostat to replace this one?

If you plug "1F56-444" into the White-Rodgers cross reference guide

From the above, it sounds like you have a single stage
heat, single stage cool, conventional fuel system.
Virtually any 24V thermostat will work with that. The
rest depends on the features you want.

I higly recommend the Honeywell VisionPro. They are
more expensive, but the touchscreen display looks great,
very easy to program. It also offers features like
vacation hold, where you can set it to hold the temp
you set for X days, then resume normal operation.
And it has adaptive recovery, which means you just
set it for the temp you want it to be at a certain time
when it resumes from being setback. It then figures
out what time to activate the system based on past
history. For example, you set it back to 60 at night,
want it to be 72 at 7AM. That's how you set it and
the thermostat then figures out what time to fire
the system up, eg 5:30 to get it there.

You can find them on Ebay.
Hi,
I like Honeywell Vision Pro. It can be unplugged from wall plate to
pogram rather than standing there programming it. They call it arm chair
programming. I have two Vision Pro 8000(one at home, one at our
condo downtown) Never had trouble since installed. Just replaced
batteries when display tells us.
