3.6.4 Connection as twin combination
With the twin combination, two indoor units are connected in series.
Withtheslaveunit,terminalSis omitted.Insteadofthat,communication
takes place between he indoor units via terminals X, Y and E.
Key to Fig. 31 and 32:
IDU-M Master unit (indoor unit 1)
IDU-S Slave unit (indoor unit 2)
▶ Connect master unit as described in chapter 3.6.2.
▶ Connect save unit to the master unit via terminals L, N and 2).
▶ Connect master unit and slave unit additionally to terminals X, Y and
E via a communication cable. In doing so, earth the shield.
Thecentral controllerandtwin combinationbothuse the X/Y/Eterminal.
For this reason, a decision must be made in advance if a twin
combination or central controller is installed.
