Hi Tim ,

Just to let you know that I tried another new sample and it worked fine. The first 2 may have been defective or were dummies as the design engineer suggested. ( the mix-up with trade show dummy units). I am able to enter command mode and am now debugging the rest of the program.

Don't worry about the humidity sensors. If you have problems contact Honeywell support and ask to talk with Gordon, the principal engineer for this product. Insist on a conference call. He will have the answers you need.
