I believe what is meant by "wired for second AC" means that line voltage (120VAC) is wired to a box located adjacent to the vent opening where the second AC will be installed. The thermostat is indeed a multi-zone thermostat but the second AC would have to be wired all the way back to the original AC's control unit and that is not typically the case.

Those who have had the second AC installed, control that AC unit locally through controls mounted on the AC unit itself. The central thermostat will not control this second AC.

I am sure there are others who will chime in who have added or had a second AC installed in their Montana's.
