I'm not real sharp when it comes to LOLcat speak, but didn't the new t-stat come with instructions?

Please be more specific. What model tstat is your old? What model tstat is your new Honeywell? What wire colors and terminals labels are they tied to on the old tstat? What cooling and heating equipment models/manufacturers do you have?
