there is a "zone a lone" switch on the upper right side of the panel. Make sure it is in the "occupied" position. I believe that is up. If that doesn't work reply back.

Hello,Message AC means that there is no 24volt power to the thermostat from the unit/s it controls.Please check all switches & curcit breakers to the unit/s as there is no low voltage power to the thremostat from the transformer in the unit/s.Maybe got turned off by mistake.

Be sure all zones are calling for cooling. Press the purge override and verify air flow on all zones. If one is still not working verify the board is sending voltage to that damper. A meter is a huge help but if all lights are on chances are the damper is stuck. You should be able to free it up but it will just happen again. Either replace damper motor, replace damper or if you can figure out if it is a "spring open" damper, get it open and unhook the wire to that zone. This will keep it open at all times because it can not "power close". Provided that zone CAN stay open all the time. Keep me posted!!
