Unique to Hitachi.
The SPX-DST1 Adapter allows for Group Controlling up to 13 RAC systems from one controller.
The optional distributor is to be used together with the wired remote controller when there is a need to centralize the
control of multiple indoor units using only a single wired remote controller.
A single distributor could be connected further to 3 separate distributors so that up to 13 units of indoor could be controlled
by a single wired remote controller.

1 x SPX-DST1 Group Control Adapter
1 x SPX-DST8M Remote Controller Cable per Indoor Unit
(add more SPX-DST1 for every distribution group in excess of four systems)
2 KEY STEPS
1. Connect Master SPX Hard Wired Controller to the SPX-DST1 Distributor
2. Connect each indoor unit to the SPX-DST1 via the SPX-WDST8M cable
