A couple of the zones go into and out of protection even though the in wall volume control are turned down or are rated at twice the power of the Architect Amplifier.
In certain situations, when the speaker wire is run through a volume control the amplifier will sense a short. The amp channel that is sensing the short will go into protection for a moment then play fine for a littel while then go back into protection. To check this, remove one speaker wire pair (+ & -) from the amp on the zone that is going into protection. This should relieve the issue and the zone doesn't go into protection. 
To solve this issue, switch the polarity of onlyone speaker wire pair at bothe the amp and at the speaker. Don't change it at the volume control. This will prevent the individual channels from sensing a short while keeping your signal polarity correct.
