My CT30 has 2 slots, with just 1 z-wave USNAP module at the moment. For the last couple of months, the thermostat stops communicating with Vera about every 5 to 7 days. I am able to unplug and replug in the module and tell Vera to "replace failed", and I am back in business.
I have moved the module to the other slot, but it acts the same. I am close to ordering a replacement module to see if that is the problem. Otherwise, I'll have to probably get a new tstat.
My point is both slots are there to be used by the thermostat. There is even a 1 and a 2 on each side of the radio tower icon, depending on which slot the USNAP module is plugged into. When I move it, it takes time for the empty slot to register and lose the 1 or the 2, and both appear for a while.
Anyone have any suggestions for a rouge CT30?
