Honeywell Zone Z311 Flashing Cool

Hi,

I have a multi-zone residential setup using the Honeywell Z311. When I call for the AC from the thermostat, the AC unit outside starts up and then stops after a minute or so. Sometimes shorter, sometimes longer. It's doing it on both zones. There is a flashing cool light on the honeywell z311 when this occurs. "Blinking when 45°F (7°C) DATS low limit mode has been reached." That is right from the manual, DATS. What would the problem be here? I had an AC guy out and he was really clueless as to what was happening. It was like he never saw a zoned system before.

Thanks for your help.

!!
