1.1 System Overview
The CooLinkHUB + CoolPlug is a solution for complete integration of Multi-Split and Mini-

indoor unit on one side, and to the CooLinkHUB on the other, via a PBUS Network.
The CooLinkHUB - protocol converter allows integration to any Home Automation system.
1.2 Network Topology
The PBUS is a Cool Automation’s proprietary Bus,
running on a shielded twisted pair cable
(24AWG).
The
PBUS utilizes free network topology (‘star’, ‘daisy-
chain’, etc.) No loops allowed.
Up to 10 CoolPlugs can be connected in a single PBUS network.
1.3 CoolPlug Models
CoolPlug models are HVAC manufacturer specific. The letters on the sticker (DK, DKS, etc.)
indicate the HVAC manufacturer the CoolPlug relates to.
