Upgrading to digital thermostat ?

[Houndog]

I have a unit the works 2 AC and 2 furnaces,, Also has 2 thermisters, one in the Gally area and one in the bedroom to measure temp.. I wish something like this would work for me,, But I can't see how it could,, Am I right or is it possible to convert mine as well ?
Thanks, Ted

Why specifically are you wanting to go to a digital thermostat? Does it get too hot before AC comes on or too cold before Heat comes on? Also let us know what make & model of units you have so we can maybe be of help.
