Installation

The remote A/B needs to be linked from the master to the slave indoor.  Also 1&2 of the interconnecting is ran from the master to the slave (connection 3 is not).

Components

A twin pipe kit is required, though not for the KRT wall mounts.

Note

Models of the same style and capacity must be used together.  They must also be installed in the same space.  One remote is used.
