Restrictions in case of mixture connection with standard indoor units
Outdoor-air processing unit
1. Restrictions of the refrigerant piping system
1) The total capacity of standard indoor units + Outdoor-air processing units should be 50-100% of
Outdoor unit capacity. (In case of using only outdoor-air processing units, it is same.)
2) The capacity of outdoor-air processing units should be less than 30% of the outdoor unit capacity.
2. Restrictions of the control system
1) In case of wiring is mixed with standard indoor units, group control by
remote controller is not available, because the setting temperature
are different.
2) When using the central remote controller, mixture of indoor units & Outdoor-air Processing
units in the same zone is not available, because the setting temperature are different.
