Lonworks® Interface DMS504C71

 

The Lonworks Interface provides control for all VRV, SkyAir indoor units, and Daikin RA and FTXS indoor units with the use of the KRP928BB2S RA Adapter. It is capable of handling a maximum of 64 indoor unit groups (128 indoor units) connected to a maximum of 10 outdoor units.

The Lonworks Interface can be used in conjunction with the BRC1E71/72 (Navigation Remote Controller), BRC2A71 (Simplified Remote Controller), or the BRC4C82/7E83/7F812/7E818/7E830 (Wireless Remote Controller), DCS601C71 (intelligent Touch Controller (iTC)) with or without the DCS601A72 (iTC DIII-Net Plus Adapter), and the DCM601A71 (intelligent Touch Manager (iTM)), with or without the DCM601A72 (iTM Plus Adapter) to control the same indoor unit group.
