Note: 1

To connect multiple indoor units to a port

Maximum total capacity of connected indoor units: WP80 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.

When connecting a WP71 through 125 model of indoor unit to an HBC controller, the pipes connecting the unit to

the same set of HBC controller ports cannot be branched out to connect additional units.

When connecting multiple indoor units including a WP63 unit to the same set of HBC ports, use a size 32A pipe in

the section indicated as "b' and c" and connect the WP63 unit to the pipe indicated as "c" in the figure.

(See page 38.)

Note: 2

Connecting WP100 or 125 indoor units to an HBC controller

When connecting WP100 or 125 indoor units to an HBC controller, connect each unit to two sets of two ports on the

HBC controller, using two Junction pipes (Y-joints). (See Fig. 11-2-1A.)

Connect an increaser (20A-to-32A) to the merged side of each junction pipe. (See Fig. 11-2-1A.)

When connecting junction pipes to HBC ports, the branched sides of the junction pipes cannot be connected to

combinations of ports "4 and 5," "8 and 9," or "12 and 13." (See Fig. 11-2-1B.)

When connecting a WP100 or a 125 model of indoor unit to an HBC controller, the pipes connecting the unit to the

same set of HBC controller ports cannot be branched out to connect additional units.

Note: 3

Maximum connectable capacity of indoor units to HBC

HBC has two pumps. Each pump can accommodate the capacity of indoor units equivalent to P175.

Make sure that the total capacity of the indoor units connected to "ports 1 through 4 and 9 through 12" or "5 through

8 and 13 through 16" will not exceed P175. (See Fig. 11-2-1B.)
