Has anyone here replaced the stock thermostat with a digital one?  If so, which one did you purchase and has the replacement been useful for you in terms of controlling heat or air more accurately?  thanks.

A new AC that would pass my draw down test was included when I bought my unit, used.  It was a Carrier 15K unit and included a new digital thermostat.  It was horribly inaccurate (~9-10° to low) until I found a Carrier website that had instructions to adjust the offsets and how to access the programs.  Once the re-set was accomplished it has been very accurate.  I suspect the selling dealer re-set it to make the new AC unit appear to be performing better than it was - I brought my own calibrated digital thermometer to check the draw down rate.  This is probably not much in the way of help, but is my experience.

P.S. Forgot to include, that instructions were also on the site, to adjust the anticipatory circuit too, and that has helped keep the humidity and temp in check.

I wonder if the mechanical thermostat can be adjusted to reduce the swing in temps.  One day I'll have to see if I have an owner's manual on that thing and determine if there is an adjustment.  We like the one we have, but not the temp swing it yields.
