3v comm hang up.
I know carrier had an issue a while ago that cause the bypass controller and air source controller to get locked in a conversation that wouldn't allow anything to happen, like going occupied. That was "fixed" through a software upgrade to the bypass. I'm wondering if this is still an issue as I had a unit similarly stuck this week and as soon as I addressed the bypass outside the scanning range of that linkage coordinator, the unit went occupied. Any thing I haven't heard about yet?
As a follow up note, I tried to reload the latest version of software to the plink and got a "checksums do not match error". Waiting to hear from the factory but I think I new to change that controller.
Incidentally, system is operating fine as long as I keep it occupied 24/7.
