T-stat question: ACONT802 vs ACONT803 - which is more appropriate for my setup?

[shaum76]

My contractor hasn't mentioned which
7-Day Programmable thermo-stat he was going to use...
I'm trying to find out which would be more appropriate.

vs

ACONT803 (7-Day Digitial Programmable 2 Heat / 2 Cool with humidity sensor)
