Zoning exterior with interior room
Zoning exterior with interior room
(OP)
Say I had a split system serving 2 rooms, one being exterior and one being interior space. I understand you should not group these two together on the same zone bc they have different cooling loads. But why can you just not have more air flowing to the exterior room and have the damper in the interior room in more of a 'minimal' position to limits its airflow from overcooling the space?

assuming the exterior wall is west facing...the exterior room will reach peak load at say 5pm, while the interior peak is say 3pm. so if the Tstat is in the exterior room, at 5 pm the indoor unit will be on satisfying the exterior room, while the interior room is being overcooled b/c by 5 pm it is no longer at its peak load.
Im assuming one would have to continuosly adjust the interior damper in order for it to not be overcooled if they were on the same zone?

but careful, you can run into the problem needing reheat due to ventilation requirements. Maybe a dedicated ventilation helps.
