I have to agree with the posters above who say you don't need it if you're here most of the time. When we're here, we just set it to whatever is comfortable. When we're not here, we set it to 83 deg. in the summer and 55 deg. or so in the winter. No problems ever with mold...and that's after living in Houston for 35 years and in south Florida for 6.
We inherited the programmable thermostat in our condo in So. FL. My husband never learned to set it.
