Second RC-80 not communicating

I have two RC-80 thermosats in the house, both connected to the OPII. The connections to the back of the stats and to the OPII are excatly the same as per instructions. RC-80 number 1 works like a champ. However, RC-80 #2 does not communicate with the OPII. I have swapped the units from one base to the other as well as changing the address (from 1 to 2) on the units and every time only the stat with address #1 communicates (no matter which base it sits on). The trobleshooting tells me that the wiring must be right and that none of the stats are defective. Any suggetions?
All setup settings are exactly the same including the "non-progrmable" option wich gives the OPII control of the settings.
 
AnthonyZ,
Yes, they were both listed under the installer setup section. However, the #2 stat had a zwave node value assigned to it. Once removed it worked 4.0.
Thanks for the help.
