Hi Gary. I have a system expanded to 32 zones. Of which 21 are configured plus 2 masters.
@Ray. Will disabling the zones I am currently not using so that I have only a couple be enough or do I actually need to delete them for the test?
I have the master zones set to Zone 31 and Zone 32 so not ideal to drop it down to 16 for a test as it will require re-wiring.
