My current aircon system was installed by Gain City 12 years with a junction box.
Consist of a system 4 (one outdoor compressor) with 5 indoor units.
They added a so-call Junction Box next to outdoor unit.
Gain City told me my master room unit is linked with my Dining area unit.
And the two bedrooms are linked with my Living area unit.
I should not turn on Living and Dining if all 3 bedrooms unit are running and vice versa.
So if we have visitors or guest , we turn on Living and Dining and don't turn on the bedrooms' units.
Is such Junction Box still avail nowadays and what are disadvantages ?
Cos one aircon guy told me such boxes will cause cooling capacity to be reduced.
The brand is Toshiba.
I am not thinking of repairing as already 12years old....planning to change to new ME Starmex.
What GainCity did 12years ago works well for me but many people don't mention such junction box or maybe called a distributor.
-- if I run two units in Living and Dining, I just don't turn on any 3bedrooms units.
-- if I run 3bedrooms, I just don't turn on Living+Dining units.
(the box just direct the cooling to the units been turned on first...)
I don't think I will run all 5 indoors at the same time so no point buying Sys5 or Sys3+2.
Does Mit Elec has such distributor box ? ( that means Sys 4 installed with 5 indoors units)
I will take a photo of the distributor box that is with my 12yr old Toshiba compressor and show you guys tomorrow.
