Upon diagnosis of units found that they can not be controlled the way customer would like them to, this unit either controls all 3 indoor units in cooling mode or in heat mode. Can not control 2 heat and 1 cool at same time.
Called tech support to verify findings and they stated that it can not control 2 modes at same time. Also there is a refrigeration leak on LG outdoor syste, which customer is aware because they have to charge system every other year.
