1. Refrigerant and water pipe size
(1) Refrigerant pipe between heat source unit and HBC controller (Part A, A1, A2, and A3)
(2) Water pipe between HBC controller and indoor units (Sections a, b, c, d, e, and g)
*Water Pipe size between HBC controller and joint is also 20A.
(3) Water pipe between HBC controller and Sub-HBC
(4) Refrigerant pipe between HBC controller and HBC controller
2. Connecting the HBC controller

(G) Up to three units for 1 branch hole; total capacity: below 80 (but same in cooling/heating mode)
Note:
1) To connect multiple indoor units to a port
• Maximum total capacity of connected indoor units: P80 or below
• Maximum number of connectable indoor units: 3 units
• Branch joints are field-supplied.
All the indoor units that are connected to the same port must be in the same group and Thermo-ON/OFF
operation simultaneously. For all the indoor units in the group, the room temperature needs to be monitored
via the connected remote controller.
