I just bought an additional 4-zone Easy Touch Indoor Control Panel to add to another part of our house. I snapped out the exiting indoor panel, which is working just fine, and snapped the new one in, just to make sure it works OK. But, it lights up and just says "NO COMM", won't communicate with the main controller. Remove, replace with the original unit, and all is OK. The back of the "new" control panel has a software date of 2007, and it's software is 1.050, Boot is 1.010 whereas the working unit is 2.070 and 1.010, respectively.
Is my "new" unit zapped, dead out of the box, hopelessly incompatible, or what? The guy I bought from said it had been sitting in the warehouse for a while, but was still new. I am not so sure. Any Pentair experts have any ideas? Thanks!
