When connecting up to four single indoor units only one multi controller is required, if more single
indoor units are needed then two multi controllers must be used. When connecting a twin indoor
arrangement to one multi controller branch the capacity code will be the sum of both indoor unit
codes.

The total capacity codes for the example above are within the maximum permitted for a 10hp
(MAR-F101HTM8-E) outdoor unit therefore the use of a twin arrangement is acceptable.
NOTE :
The maximum duty from the system cannot exceed the maximum capacity of the outdoor
unit, it is possible to use indoor uits with a total capacity of 135% of the outdoor unit capacity.
