Product review (1 stars): Stay Away From ACU-RITE
Seems to be a nice item, but unless the outside temperature is 158 degrees I'd say it isn't working. Thinking perhaps I needed to program the item, I called the "24/7 Customer Support" line.  1st try.. After 1 hour a recording says "there seems to be an application error, BYE".  So I called back...same thing after 40 minutes.  Three strikes and you're out as I have now been on hold almost 2 HOURS because "all of our representatives are still assisting other customers"....  Had to hang up as the battery in my cordless phone was dying.  BAD company to deal with!
