Hi Larry,
Advent Air has been having issues with compatibility recently so I would recommend going with a Furrion unit instead to ensure it would work. You'll also need to remove the cover of your air distribution box and see if the controller is mounted to it or if it's built into the rooftop unit. If it's built into the rooftop unit you can see if you can mount it to the air distribution box, otherwise you'll unfortunately need to replace the whole system.
For just the rooftop unit you'll want the Furrion Chill HE # FR42PV. For the entire system you'll want part # FR92PR if you want the controls built into the air distribution box or the # FR55PV if you want a wall-mounted thermostat.
